Grow Your Business with Tree Journey

Spanish moss, an epiphyte, a flowering air plant; whatever you know, this plant is a common plant to see growing on oak trees. The signature wispy tendrils and hanging vines make this plant easy to recognize. 

Spanish moss is an epiphyte which means that it is an air plant and does not rely on its host for nutrients. Instead, Spanish moss gets its nutrients from the water and other particles in the air around it. Spanish moss is generally fine to leave on your oak tree unless it’s weighing down branches.

Is Spanish moss a good thing or a bad one? Should it be removed or left alone to flourish? Truthfully, it depends on your tree and your own situation. Spanish moss is not intrinsically harmful to oak trees, but there are some factors to be aware of. 

Should You Remove Spanish Moss From Oak Trees?

To keep it short and sweet: no. It is not necessary for you to remove Spanish moss from any oak trees. Unless you simply prefer the look of a tree without it, you do not have to worry about Spanish moss negatively impacting your oak tree.

Spanish moss uses its long stems to wrap around an oak tree and, to the naked eye, could look menacing. You might fear that this plant is taking nutrients from your beloved tree, and that is not something most people view fondly. 

However, this is not the goal of Spanish moss. In fact, the University of Florida IFAS Extension tells us that Spanish moss is not moss at all. Instead, Spanish moss is a bromeliad which is a plant more akin to popular houseplants and is even related to pineapple!

You may be reading because you were concerned that this plant was going to destroy your oak, but you also may just be curious to learn more about how Spanish moss works and what you can expect from it. 

So, without further adieu, let’s talk Spanish moss.

What Are Some Benefits Of Spanish Moss?

Spanish moss is really the opposite of a parasite in the sense that it helps the organisms near it. 

The only occasion where Spanish moss might not be great for a tree is if the tree is already dying or declining, in which case the harmless flowering plant may weigh down the brittle branches a bit too much.

However, the pros actually do outweigh the cons, in a funny change of pace from what we usually expect when we hear about a foreign entity growing on our oak trees. 

Animals Use Spanish Moss For Protection

Animals tend to take cover in the thick growth of Spanish moss because it helps protect them from elements such as rain, wind, and cold temperatures. 

Birds like to use Spanish moss to build up their nests due to the soft yet clumpy material that pairs quite well with other nest-making resources. 

Spanish Moss Can Withstand Droughts

The way that this plant works is that it can hold on to the water for long periods of time, thanks to the lack of roots or connection to the soil.

The tissues of the Spanish moss can hold more water than the plant needs at a given time, which allows it to store up some extra resources in the same way that squirrels hoard acorns or deciduous trees lose their leaves in order to retain water. 

Spanish Moss Adds Color To A Tree

When all else fails, you can count on Spanish moss to add a pop of deep green to your space. Unless there has been an extremely dry period and the water is used up, which turns the plant to a grayish hue, you can expect Spanish moss to be a beautiful shade of green.

Does Spanish Moss Hurt Oak Trees?

There is really not much that Spanish moss can do to hurt an oak tree. The only potential difficulty Spanish moss may pose is to a tree whose limbs are fragile for whatever reason. Since this plant uses an oak tree for support, too much of it may work to weigh down weak branches. 

In fact, trees that are already dying or declining usually see the weakening of branches and the thinning of leaves. Once the canopy is more sparse, the environment for Spanish moss to grow is even better as more light is let in through the remaining leaves.

So, the older a tree gets, the more of a potential issue Spanish moss may become.

If you know if your oak tree is weakened, take a look at our guide on what may be wrong with your oak tree.

If you think about it, Spanish moss could hypothetically grow at a rapid rate and create shade that would inhibit leaves and new branches from growing on an oak tree. That’s the hypothetical viewpoint.

Realistically, and based on what usually happens, healthy oak trees grow much faster than this air plant and are much too large to feel an extremely negative impact of Spanish moss.

If you want to have Spanish moss removed, we recommend that you find a trained arborist near you to ensure that you do not damage your tree in the process.

Why Does Spanish Moss Grow On Live Oaks?

It’s plain and simple, really.

Spanish moss grows on live oak trees because they provide a stable environment for the air plant to survive and flourish. Oaks are tall, sturdy, and adaptable trees – the perfect conditions for Spanish moss to hang and grow.

We mean that both figuratively and literally, by the way. Don’t forget that Spanish moss hangs from the branches of oak trees. 

The way that Spanish moss hangs allows it to pick up moisture and nutrients from the air around it. This plant prefers a moist environment; though, as we’ve discussed, they can also keep up with the best of ‘em in a drought.

Even though Spanish moss is pretty adaptable itself, it prefers a host that is also going to be a safe bet. The longevity of an oak tree means that it survives natural disasters frequently, and most live lives that span from hundreds to a thousand (or more, in some cases) years. Talk about resilience!

If you’re not sure about what type of moss is on your oak tree, take a peak at our oak oak tree moss identification guide here.

How Quickly Does Spanish Moss Grow?

Spanish moss grows at a rather acceptable rate.

Spanish moss, like most other air plants, can grow about 4 to 8 inches per year. That may sound like nothing at all, but keep in mind that this is a relatively small, wispy plant that hangs from the branches of trees.

On the other hand, in comparison to a tree, that is nothing. So, when we say that an oak tree is going to grow much more quickly than Spanish moss and that an infestation is highly unlikely to slow down the growth of the oak, that is what we mean.

Does Spanish Moss Act As A Parasite?

You may be thinking this because of mistletoe and how it can take away nutrients from a tree over time.

In truth, Spanish moss is actually considered an air plant which means that it gets its nutrients from the air and not the organism it is living on, like your oak tree, for example. Spanish moss is not parasitic to trees.

Spanish moss tends to live on trees because they are tall and can eventually offer a good boost to get water, fog, debris, dust, pollen, and other airborne sustenance. 

If there is no water in the atmosphere and not enough rain, Spanish moss will fail to sustain itself. Even in cases like this, it would be unable to take on parasitic qualities if it tried (which it doesn’t.)

Light and moisture themselves seem to be much less important than what nutrients the Spanish moss can accumulate from the air around it.

It’s all well and good that Spanish moss isn’t going to damage my oak tree, but what is it actually used for? Are there any ways I can utilize this plant?

Glad you asked, yes! There are some pretty cool ways that Spanish moss is utilized once it is removed from an oak tree.

What Can You Do With Spanish Moss?

Spanish moss can be used for a wide array of things, from industrial materials to decorative placements.

If you have Spanish moss growing on your tree, it can be utilized for many things. If this becomes a factor in an area where you have many trees, the moss could be harvested for use on a larger scale. 

Luckily, we won’t leave you hanging around like Spanish moss. We’re going to give you some examples of the way that this moss can be used in everyday life.

Spanish Moss Can Be Used As Stuffing And Packing Material

Some years ago, Spanish moss used to be a big name in the stuffing materials field.

Thanks to the University of Florida’s IFAS Extension, we know that Spanish moss was commonly chosen to produce the stuffing for the seats in cars, cushions on couches and other furniture, and even mattresses. 

Imagine you get home from a long day at work; you’re driving in your car and looking forward to sitting on the sofa to watch some TV before bed. At one point in time, all of those seats and places of rest alike could have been stuffed with the same thing: good ol’ Spanish moss. 

Now, in a more modern era, Spanish moss is more commonly used as stuffing or packing material that does not necessarily relate to furniture and or other places you’re likely to sit or lie down on.

Surely that’s not all that Spanish moss has been used for, right? 

Right!

Spanish Moss For Insulation And Bousillage

Before the age of using Spanish moss as a packing material more than furniture stuffing, there was another household use.

The National Center for Preservation Technology and Training can teach us a thing or two about the way that Spanish moss was used as insulation. Bousillage is the name of a type of construction method local to Lousiana, one of the hot spots for Spanish moss to reside. 

Blending multiple cultural traditions, both French and Native American, much like the culture of the state, resulted in a technique that combines Spanish moss and clay to create a mixture that fills in cracks and crevices of buildings. 

This is quite an old technique and one that takes time, patience, and some skill, but it is a wonderfully historical process to learn about. 

Spanish Moss As Decorations

Nowadays, if we’re honest, Spanish moss really only has two popular uses. One of which, decoration, might be less practical, but it has its merits. 

Products like this Super Moss Spanish Moss, which is both dried and has enough practical uses of its own, can be found online and in local craft stores.

It can be simply added to floral arrangements for an extra bit of ‘oomph,’ or you can style an event or another piece of decor with this plant. Really, it’s whatever your heart desires.

Spanish moss is good for special events decor, like when you are sticking a name card into a vase and needing some extra ‘filler’ to hold the card up. Perhaps you’d use this to dress up some of your indoor succulents or to provide a backdrop for some other windowsill decor.

Let your crafty side fly free and know that whatever you opt for is going to be a good use for Spanish moss!

Spanish Moss Can Be Used As Mulch

Spanish moss has been known to be used in mulch, which is the other popular current-day use of the product.

Spanish moss helps hold moisture and retain soil, so what better addition to this year’s pile of mulch? 

Not only is it a pretty addition to all kinds of decor, or a relatively harmless hanging plant, it also can help support new plants as they begin to grow and flourish.

Mulch is used similar to fertilizer as nutrients for an oak tree. If you’d like, you can read more about the best fertilizers for oak trees here.

That’s Moss-tly It For Now!

Okay, ignore the bad pun but we’re trying over here!

Now that we have learned a little more about Spanish moss, its pros and cons, and even how to remove it if you still prefer that path of action, it’s clear that this air plant is versatile, pliant, and pretty darn cool.

Remember that Spanish moss is not a parasite. It just likes to hang out and take some water and nutrients from the air.

We hope that this article helped you understand the ways in which Spanish moss operates. 

Until next time… thanks for reading!

We all love our beautiful oak trees, and we want to always make sure they are in good health. With an ample amount of sun, water, and nutrients – oak trees flourish. The truth is – sometimes we don’t even have to intervene, as an oak tree is self-sufficient and can take care of itself.

Young oak trees under five years old should be watered. Your oak tree may need water if its branches are brittle, easy to break, and leaves prematurely falling. When watering your oak tree, deeply soak the surrounding soil to about 1-2 feet downwards to ensure the water reaches the roots.

But not all oak trees need water, and today, we have some simple tips that you should know before you go and water your oak trees – and to be honest, these tips can even save your oak tree’s life! I know there is a lot of pressure here.

Does My Oak Tree Need To Be Watered?

Before you pick up the hose and water your oak tree – this is the question you need answered. Does your oak tree actually need to be watered? Right off the bat – the answer is – most likely not. But there are three questions you need to consider before you start to water:

● How old is your oak tree?

● Is your oak tree in good health?

● Are you in a drought?

These three questions are all you need in determining if your healthy oak tree needs water – and they all require different solutions. But let’s talk about the tips, and we will get back to this later on.

10 Simple Tips for Watering Your Oak Tree

So – let’s get to it! If you think your oak tree is in need of water, it’s essential to water it the right way. Under-watering or overwatering can do harm to your oak tree, so it’s best to keep balance – and we’re going to tell you how.

Add 1-2 Feet Of Water Around the Base Of The Oak Tree

First things first, if you have determined your oak tree is in need of water, a good rule of thumb is to add water in a 1-2 feet diameter around the tree.

Creating a bit of distance rather than just hitting the trunk with the hose and adding a little water is going to be way more beneficial to the oak tree and will allow it to actually get the water it needs.

We often think we are watering our oak trees and other plants enough by simply just spraying some water on them.

You have to imagine how big the oak tree’s roots are, and then with that mindset, try to visualize the amount of water it needs.

Deeply Water The Oak Tree And Fully Soak The Soil

As simple as it sounds, really saturated the water in the soil here.

We use the term deep here because you have to add water that will be deep enough for the oak tree’s roots. Again, with the same 1-2 feet in mind, although it may be hard to tell from the surface, the goal is to fully soak the soil so that it remains wet from the surface to 2 feet below.

Just wetting the surface of the oak tree isn’t going to do anything because all that does is wet the soil. An oak tree’s roots are underground, which means you have to add enough water so that the water can surpass layers of soil.

To do this, it’s best to leave a hose or sprinkler system or, if you are using drip irrigation, on anywhere from a half-hour to an hour to soak up the soil around the tree. But there is a tip with sprinklers that you have to consider as well.

Don’t Put The Sprinkler Right On The Trunk Of An Oak Tree

The whole goal of using a sprinkler system is to wet the soil around and under the tree – not by soaking up the trunk!

Having the water from a sprinkler constantly hitting the trunk for a delayed period of time can cause harm to the trunk, especially if the sprinkler has high water pressure. The oak tree’s trunk can start to peel, or the water itself at high pressures can harm the bark and will wound the tree.

A wounded tree means it needs extra care because it can obtain diseases and insects will be attracted to the wounded spots, and the oak tree can become infected.

Don’t Overwater The Oak Tree

What we just spoke about definitely consists of a lot of water, but it all leads back to if your oak tree even needs water in the first place – which we will talk more about later. However, if you have come to the determination that it does – do not overwater your oak tree.

Some signs of overwatering of an oak tree are yellow leaves on the lower branches of the oak tree or within the canopy or brittle leaves. Another way to check is to simply dig into the soil. If you dig about 8 inches down, the soil should be cool and damp – not wet or not puddling.

Plants and trees can only suck in so much water at a given time. If the oak tree is overwatered, the roots won’t be able to take in air because they will be drowning from the water.

Overwatering can actually kill an oak tree or lead it on a downward spiral of health.

Don’t Water Oak Trees In The Winter

In the winter, oak trees are dormant, and oak trees do not need water because they do not need as much as they would in the warmer months.

In the winter, leave your oak tree alone and let it take in any natural precipitation that occurs. With colder temperatures, there is less evaporation and more water on the ground, and sometimes, it’s even frozen water.

If you’re wondering just how the heck oak trees make it in the cold, check out our piece on how oak trees survive winter here.

Mature Oak Trees Shouldn’t Be Watered

The biggest takeaway here is that if you have matured oak trees – they don’t need to be watered unless there are significant signs that it isn’t getting water.

Mature oak trees have been doing their thing, so to speak, for a long time, and they know how to get nutrients, and they know how to be self-sufficient. At around five years old, your oak tree will be in a great spot to take care of itself.

Oak trees aren’t mature until about 20-40 years, so you may still water your young oak once or twice a month until then.

Mature oak trees get their water from the soil and are considered such easy-to-grow plants because when they become mature, they really don’t need any intervention from us.

Fun Fact: Oak trees produce acorns around 20 years old!

If Your Oak Tree Is Young, It Needs Water

On the contrary, if your oak tree is young – it is going to need a lot of water!

There is a whole watering plan for young oak trees that we will talk about later in this article!

The rule of thumb is to start off watering your young, newly planted oak tree at least 3 times a week, to 1 time a week, to every other week, to every month, to every few months – and beyond. Young oak trees are going through a lot of initial shock since they are being ripped from their environments and planted into new ones.

During that process, they learn how to function and maintain a steady routine.

The biggest factor here is that a young oak tree or newly planted oak tree hasn’t developed deep roots yet, and the roots may not be able to reach the water that is in the ground.

Because of this, your young oak trees may not be getting any water at first, so it’s essential to provide ample amounts of water at a time.

While oak trees need a good deal of water, they also need sunlight. You can read more about how much sunlight your oak tree needs here.

If There’s A Drought, You Can Water During Winter

Even more on the contrary – if there is a drought, you can water during the winter months – but only if the temperature is right.

If the temperature is above 40 degrees and there hasn’t been much precipitation, then depending on the age of the tree, your oak tree may need some watering. If there are warm winter days, it can actually awaken the roots, and the problem that occurs then is that there is no water during a drought available for the roots to drink.

If the ground is frozen, you should not be watering your oak tree. Water will not be able to seep through the ground, and it will do nothing for your oak trees. Plus, if the ground is frozen, the roots remain dormant.

Adding water can actually cause harm to your oak tree if the ground is frozen because it can warm up the frozen ground, the water will not seep through enough for the roots to take a drink and can actually evoke the roots to come out of dormancy, and if they do, there won’t be any water supply for them.

Keep Fallen Leaves Under Oak Tree

A nice little tip to helping your oak trees get enough water, especially in the Autumn months when they are going to start to go dormant, is to keep the fallen leaves on the ground where they fell!

These oak trees’ leaves will act as a natural mulch and will create a layer that locks in moisture and will eventually decompose and provide a ton of nutrients to your trees.

All parts of the tree are beneficial – so letting it do its own thing, and keeping its leaves on the ground, will only benefit it in the long run.

Refrain From Planting Under An Oak Tree

One last tip – although it doesn’t directly apply to watering, it is something you should know is that you should never plant under your oak tree.

Your oak tree will be in a constant war with any plants near the base of the oak tree for water and air, and because the plant’s roots will be closer to the surface, the plants will be seeping up the water more quickly leaving the oak tree without water.

So, while those flowers might look beautiful, plant them somewhere else!

Does Your Oak Tree Need Water?

Now that you know some tips for watering – before you do, it’s important to consider these things below. So, let’s revisit those three questions from early on.

Young Oak Trees Need Water

If your oak tree is brand new to this world, and you just planted the oak tree – you should water the tree three times a week for the first three weeks it’s planted. Aiming for a total of about 15-20 gallons in the weeks’ time – will help keep your tree hydrated.

After about three weeks, you can water your oak tree again. But it will only need to be watered once a week. Aim for about 10 gallons of water per week until the oak tree has been planted for two months.

Once your oak tree has been planted for two months, for the next four months, water your oak tree every other week – anywhere from 10-15 gallons of water.

Continue like this, watering the oak tree every other week for about a year, but if it rains a lot one week – the oak tree does not need to be watered, as the rain took the watering spot.

After the first year – your oak tree can be watered once a month; however, if it rains, it will not need to be watered.

Going up to five years of age, continue to water your oak tree once a month, only if needed.

Mature, Healthy Oak Trees Don’t Need water

Checking to make sure your oak tree is in good health is key in determining if it needs water or not.

First, inspect the soil around your tree – if it is really dry, there is a good chance it needs water. If the soil is moist, it doesn’t need water!

After the soil test, give your tree an overall scan from the top of the canopy to the base of the trunk. If the trunk looks in good condition, and the leaves are green and full of life – you won’t need to water it.

If you think that your oak tree may not be healthy, check out our guide on what may be wrong with your oak tree.

All Oak Trees Benefit From Water During A Drought

Being in a drought changes things. It’s like your plants, and oak trees are in a state of emergency, and the normal water supply that they have from the ground is just not cutting it!

If you are in a drought, definitely water your oak tree. You can do this by putting a hose at the base of your tree and allowing it to stay there for 1-2 days, but at a very low pressure – almost dripping.

If you are in a drought and it’s during the winter months, you can water your oak tree once a month, depending on the climate. But – do this with caution because the ground cannot be frozen if you decide to water your trees.

How To Tell If Your Oak Tree Needs Water

Besides these three questions, there are visual signs to tell if your oak tree needs water because although those questions help to decide when a healthy oak tree needs water, there sometimes are expectations.

Below is a list of something to look out for to see if your oak tree needs water:

● Dry soil underground.

● If your oak tree has wilted leaves.

● If the leaves of the oak tree are turning brown at the tips.

● Undersized leaves.

● Spotty canopies, where leaves are missing in chunks.

● Scorched leaves.

● Yellow Leaves.

If you come across any of these signs, the first thing you should do is water your oak tree. If things do not get better, your oak tree may be unhealthy.

If you start to notice a quick decline in your oak tree’s health and appearance, it may be lacking in nutrients, and water may not be the issue.

Fertilizing Your Oak Tree

Sometimes, if your oak tree isn’t looking too good – it may have nothing to do with water at all. It may be lacking in some nutrients, and if that’s the case, you may need to fertilize it.

Fertilizing oak trees is relatively easy, but fertilizing needs to be done correctly to ensure the health of your tree. Fertilizing oak trees usually consists of a 12-4-8 ratio of Nitrogen, Phosphorus, and Potassium.

To fertilize your oak tree, always make sure to lay the fertilizer at least a foot away from the trunk so that the tree can get the nutrients.

If the fertilizer is close to the trunk, just like if water is too close to the trunk, it will not do much for the tree and can actually damage the trunk and bark itself.

Whether it’s by laying the fertilizer around the oak tree trunk or by taking a more proactive approach and digging quarter size holes that go about 18 inches down around the tree, and then filling those holes with fertilizer, if your oak tree is lacking in nutrients and is looking unhealthy, the fertilizer will help it.

You can read our full guide on how to fertilize your oak tree here.

That’s A Wrap!

Oak trees don’t always need as much care as you may think. They are relatively easy-to-grow trees, and once mature, they are self-sufficient and can flourish on their own accord.

However, sometimes our oak trees need water, and especially at a young age, they need a lot of care and water.

If you sense your oak tree needs water, definitely lookout for some signs and take these tips to help your oak tree. If you realize water isn’t the issue, then we advise calling a professional to see if your tree has a disease or is unhealthy.

Oak trees are one of the most common species of deciduous tree, not to mention that they top the list of most well-known trees. Their signature fruit, the acorn, provides food for wildlife while their leaves spread to offer cover from the weather of any sort. 

Oak trees grow more efficiently in direct sunlight. Oak trees are intermediately tolerant to shade, meaning that they can still grow effectively in the shade and don’t always need direct sunlight. However, oak trees will grow best with 4-6 hours of direct sunlight per day.

So, do oak trees need a certain amount of sunlight to survive? Do they adapt to areas that are not very sunny on a day-to-day basis? Truthfully, like many other organisms, oak trees just need a healthy balance. A mixture of sunlight and shade will go a long way to this tree’s long life. 

Do Oak Trees Need Direct Sunlight?

There’s no question about how oak trees do with lots of sunlight. With a canopy that can both protect from too much sun while also bouncing around the light into patterns at different times of day, oaks are a wonder.

Their signature lobed leaves, varying in shape and texture but always fanning out in a spectacular array, are just a single factor of many that characterize this marvel of nature. 

While most varieties of oak prefer as much sunlight as they can get, this is not a necessary condition to promote growth. 

You may be imagining a space with no other trees, just access to direct sunlight, good soil, and a healthy amount of water… and that’s great. However, most oak trees can thrive in locations that allow them to get only a little sun each day, even if the majority of the time, they don’t receive much direct access to the light. The forecast can still be cloudy with a chance of oak trees!

You are, most likely, reading this because you are worried that your oak tree will not thrive without constant sunlight.

Well, we have some answers to your questions, so keep on reading and let’s get into it!

Can Oak Trees Grow in Shade?

Can oak trees grow in shade is one of the most frequently asked questions that prospective owners of these trees ask, and for good reason. 

It is important to be knowledgeable about the plants that you are opting to take care of, especially when it’s new to you. Whether the species is a different one than you’ve looked after, or you’ve never planted a tree yourself, or even if you’ve just found some new curiosity about that which has been in your yard for years, seeking information is always a great step.

Thanks to the University of Tennessee Extension, we know that oaks tend to fall on the scale of intermediately tolerant to shade through intolerant to shade. 

What does this mean, exactly? 

Trees that have a high tolerance to shade can grow in areas where little light is available. Relatively, there is not a huge impact that occurs when light levels are lower. 

Shade intolerant trees, however, are a different story. These types of trees don’t grow well in low-light-level areas, but they thrive indirect and more consistent sunlight. 

Somewhere in the middle of this spectrum is a tolerance known simply as ‘intermediate.’ 

If trees that are very shade tolerant are planted in full sunlight, this can cause stress on them as they are receiving much more light than they need. Inversely, those that are very intolerant to shade face a similar struggle when planted too close to other trees or areas that are shaded for whatever reason. 

This is why it is important to have a good understanding of the basic needs of your species of tree. 

Oak trees, falling on the range of shade-intolerant to intermediately tolerant, do well at the edge of forests, near peaks that provide a brief respite from the sun, or in any other area that allows for a combination of sun and shade. 

Since oak trees flower, they fall into the category of trees that simply needs enough sunlight to foster the bloom and eventual fruit-bearing of the tree itself. 

Flowering trees, like oaks, need anywhere from 4-6 hours of sunlight a day. 

Of course, if there is a little more or a little less shade in your area, it will not be the end of the world or your tree. 

What Else Do Oak Trees Need Besides Sunlight?

On the same page, there are other factors that go into growing an oak tree to maturity. Sunlight is great, and it is important to keep this major factor in mind, but things such as soil, water levels, and average temperatures also play a large part in successful oak tree development. 

Oak trees are adaptable in the sense that they can thrive in differing soil conditions. Almost opposite from the way that they thrive best in certain light levels, they are more readily flexible when it comes to their soil. 

Similarly, some species do very well with excess water, like the kind that occurs during a flood, while some are more able to adapt when there is an impending drought. Of course, a happy medium is always the goal, but these trees do not easily give up when conditions are less than perfect. 

These statements are also all dependent on which species of oak is in question when it comes down to it. 

For example, a Water Oak is well-adapted to a swampy, wet area but can tolerate a climate that is a bit more well-drained. The Blue Japanese oak, on the other hand, prefers a space that is well-drained and has better access to direct sunlight. 

Both of these oaks could do well enough to swap environments, but they just might not thrive in the same way they could in their favorable conditions.

How Long Does an Oak Tree Take to Grow?

If we are talking about from seed all the way through to maturity, it takes an oak tree an average of 30-40 years to grow.

Of course, this is not the end of an oak’s life span. Once the tree is mature, it depends on biology, external forces, and even a little luck to determine how old the tree can actually get.

Remember, plant your oak tree in a spot where it can get proper sunlight.

If you’re interested in learning more about the lifespan of oak trees, check out our oak tree lifespan guide here.

What is The Best Fertilizer for Oak Trees?

If an oak tree is located in an optimal environment, healthy, and faces other good external conditions, it should not need any supplemental fertilization. 

The best fertilizer for an oak tree is natural matter containing nitrogen. This can come in the form of fallen leaves, animal excrement, or other composted materials.

However, this is the ideal situation- not the most common one. A little extra nutrition never hurt anyone, right? 

In areas where organic matter is not present (like when leaves are raked away from a tree in the fall), an oak might require extra fertilization.

While there’s a little more to it, you can read more about using the best oak tree fertilizers here.

What we’ll describe below works well; you should check out the article above for the best fertilizer ratio.

Using Natural Compost for Oak Trees

This can still be done naturally, using composted materials from your daily life. 

If you have the space on your property, create a compost pile that you designate for your leftover produce. This is a quick way to up-cycle food scraps, save money, and avoid quickly overfilling your trash bins.

In areas that are a bit more urban, invest in a compost bin. This helps you to avoid the necessity of space, where you can pile lots of scraps in the back corner of your yard. 

Compost bins also keep bugs out, the smell in, and as a bonus, they look neat and tidy!

The VIVOSUN Tumbling Composter Dual Rotating Batch Compost Bin offers everything you need to start composting safely, correctly, and beneficially. 

You can add this composted matter, which turns into soil, around the base of your tree for a natural, easy method.

When Should You Plant An Oak Tree?

Oak trees should be planted any time that the ground is not frozen. The latest they should be planted is in the late summer or early fall period. This allows the ground to still be rich from the summer months without being frozen by the winter temperatures. 

Spring is a prime time for planting because the ground has just thawed, and the roots will have a couple of seasons to fully establish themselves before the ground freezes again.

4 Tips for Planting an Oak Tree (& Getting Proper Sunlight)

Oak trees are wonderful, with so many beautiful species to choose from. If you want to continue to see oaks all around and benefit from their air cleaning and wildlife supporting qualities, you can plant an oak of your own!

If you already have oak trees on your property and don’t necessarily want more, that’s okay! However, planting an oak from a seed or a sapling is easier than you might think. 

Lucky for you, we have 4 simple tips that you can refer back to when it comes time to plant your very own oak tree. There are a few considerations that will might your life easier, allow your tree to flourish, and help maintain the balance of your particular regional ecosystem. 

Curious yet? Keep reading!

1. Choose a Location Filled With Sunlight

Location, location, location. 

It always comes back to location. Whether we are considering the balance of direct sunlight to partial and total shade, the soil quality and type, the average temperature of a region, or even the wildlife around, where you decide to plant your tree is a big decision.

Take the time to do your research about the best growing conditions for anything you are deciding to plant, but especially for a tree that will grow so large and last so long.

MAKE SURE your oak will get adequate sunlight where you put it.

To learn more, check out our guide that will help you decide on the best places to plant an oak tree.

Of course, it’s VERY important to plant your oak tree in the right location. Take a look at our guide on the best places to plant an oak tree here.

2. Protect Your Young Oak From Wildlife

If you are concerned that wildlife may cause a detrimental impact to your sapling or even a tree that has been growing for some time but is nowhere near mature, this section is for you.

Using fencing around your trees, at least around the base, is a good way to protect them not only from animals but also from things like overzealous lawn mowing. 

Something like this Voglund Nursery Mesh Tree Bark Protector offers a good amount of protection while managing to not do too much in the way of obscuring your tree itself. 

The mesh tree bark protector is also great for trees of different sizes with different needs, thanks to the offering of mesh from 12 inches tall up to 48 inches tall. 

3. Select The Right Soil

Remember how we talked a little bit about different oak species thriving in different types of soil? 

Well, this is where some personal research comes in. You’ll want to check which species of oak it is that you are planting and then decide if you are in an area with the right soil. 

Hold on a minute… does that seem backward?

Unless you have a very specific preference for oak trees for whatever reason, learning more about your natural environment should be your ultimate first step. 

If you have soil that is moist but well-drained, you might opt for white oak. You want to give this species a little extra space to really develop, but it is most commonly used in lawns or as a shade tree. 

Additionally, the white oak is particularly versatile, meaning that it can also manage to hang with the best of ’em during a drought or an unusually rainy season. 

A pin oak, on the other hand, does best in soil that is acidic yet rich and moist but well-drained. This would be an important thing to know before buying and planting this species and then going on down the road to wonder why it isn’t thriving in a semi-arid climate. 

4. Properly Size The Oak Tree Planting Hole

Roots are meant to grow, expand, and provide an increasing amount of nutrients to a maturing tree. So, digging a hole that seems a bit small off the bat is not going to be a good way to start your relationship with your oak tree.

Instead, try to create enough space that you can easily sit your sapling in and then fill it back in with soil from there.

Breaking up the soil and then filling it back in is going to be a much more sustainable and fruitful method than trying to squeeze the base of your tree into a space that is too small. 

Think about house plants, for example. As a plant grows (whether it be morning lily, basil, tomato, other herbs, or any other sort of domestically-based potted plant), it often requires repotting at regular intervals. 

Have you ever considered why this is? Well, the roots grow in a way that each little piece gets larger, but the root system as a whole also expands outward, downward, even upward. If the plant was left in a pot far too small to facilitate this growth, it would be stifled and stop having opportunities to thrive. 

It is for the same reason that a sapling, or even a seed itself, needs some space to breathe as it grows and develops. If the soil is not maintained or a hole is not quite large enough, or any other number of factors combine in the right way, your oak tree will begin to struggle and likely miss important benchmarks for growth.

If you’re interested, you can read more about the best oak trees to plant here.

That’s a Wrap!

To tell you about how much light oak trees need, some best practices for growing and planting, and getting into some of the details about oaks that aren’t always as commonly known. 

Now that we have learned more about growing an oak tree from the planting stage in the soil to the growing stage in the sun, it’s clear that these trees are a good kind to keep around.

Oaks tend to be adaptable, strong, steadfast, and beautiful trees that can thrive in so many different environments. 

Keep those few tips in mind, and you’ll be able to watch your oak mature before your eyes!

We all love those tall, mighty oak trees. They truly are a sight to see, and they are not only beautiful but bountiful and do so much for our environment. But the truth is – we’re not the only living thing that loves them. Caterpillars absolutely adore oak trees, along with wildlife and insects – but our oak trees don’t adore them back.

Caterpillars eat the foliage of oak trees and their webs inhibit tree growth. To get rid caterpillars on your oak, you should have the oak tree cared for by a professional to remove the caterpillars. You should also attract natural caterpillar predators, such as birds, to flock near your oak tree.

Today, we’re going to discuss why caterpillars are on your oak tree and what you can do to get rid of them! Keep on reading to find out more.

Why Are Caterpillars on My Oak Tree?

During the spring and summer, you may see thousands of caterpillars on your oak trees. Yup, thousands. An oak tree is a host plant to many species of caterpillar, and when the weather starts to heat up – it is caterpillar season.

Caterpillars tend to migrate towards oak because of all the benefits oaks have to offer. Oak trees offer shade, they offer shelter, and they offer an endless amount of food that will regenerate as long as it doesn’t get destroyed by a caterpillar infestation.

Caterpillars typically appear from the spring to the fall to feed on leaves. Once they literally stuff themselves with leaves and grow plumper, they then hang from the tree, spin their cocoons, and will be dormant from late fall to early spring – where they then emerge as butterflies. 

I mean, the truth of the matter is – oak tree leaves are part of a caterpillar’s life cycle, and they will find safety in your oak trees so that they can cocoon.

So – why would we need to get rid of caterpillars?

Caterpillars Are Bad for The Health of Your Oak Tree

I know; I feel bad for the caterpillars too. They are small, vulnerable little creatures that only are looking to feed and feel safe. I mean, technically, that’s what every animal wants, right? Okay, sorry to get all philosophical here, but it’s the truth!

And the other thing is – we’ve all grown up with the “caterpillars turning into butterfly metaphors” as part of our life – but the truth of the matter is – as beautiful as they become, caterpillars can do a lot of ugly to our oak trees.

Since both caterpillars emerge and oak trees come out of their dormant stage in the spring, the caterpillars can be detrimental to the health of the tree, especially if they are eating all the leaves and buds right when it’s waking up.

The problem with caterpillars is that it can lead to tree-wide destruction and make the oak tree lose all its leaves. The webs of caterpillars can be wound so tightly around branches that the oak tree loses the necessary air and sun needed to survive.

At face value, caterpillars are not so bad, and the tree can generally recover – however, the problems start to occur when there is an infestation, and the best way to avoid that is by prevention.

If your not sure if it’s caterpillars in your oak tree, you can view our checklist for what may be wrong with your oak tree here.

Simple Tips to Get Rid of Caterpillars in Your Oak Tree

There are a lot of things that you can do right now to protect your oak trees from caterpillar damage and pests in general. There are also ways to get rid of them – if they already became a problem. Either way, you should act quickly to avoid any unnecessary damage to your tree.

9. Remove Caterpillar Webs Off The Oak Tree

If you start to notice a lot of webbing around your oak tree – there is a good chance it’s caterpillars and not spiders! This is one that you can call a professional removal service for (to reach those high up branches), but removing the caterpillar webs from your oak trees may be something that needs to be done.

If you see a few caterpillar webs, there is a good chance your oak tree will be okay; however, if you start seeing more webs, and more webs, and more webs – it’s time to take some action because you will have an infestation on your hands soon.

Removing the caterpillar webs should be done in the winter when the caterpillars are dormant. Removing the webs can be done by pruning the branches of the oak tree that the webs are on. Further, if you see any larvae on trees, it may be a good idea to prune those branches as well.

Cutting off any leaves that have webbing on them is also a good way to prevent an infestation and get rid of your caterpillar problem.

8. Spray Your Oak Tree With Neem Oil

If you rather go an even more natural route – you can spray the oak tree with neem oil to get rid of the caterpillars. Neem oil needs to be diluted and should be mixed with water and something like dish soap – as an emulsifier and then can be sprayed onto the infected areas of the oak tree.

Neem oil is a natural product that can be found organic. Depending on the type of neem oil used, it can also be utilized as an indoor pesticide.

If you are looking for a high quality neem oil, check out Organic Neem Bliss 100% Pure Cold Pressed Neem Seed Oil.

7. Use a Non-Toxic Pesticide On The Oak Tree

Using a pesticide such as Bacillus thuringiensis can help with your caterpillar problem but will not be harmful to the tree and will not be harmful to any other insects unless specifically listed on the bottle.

Bacillus thuringiensis is a naturally occurring bacteria in many soils. So it is typically natural and will not harm your tree.

Using a trigger spray bottle or pressure tank sprayer, mixing Bacillus thuringiensis with water and applying it to the affected areas of the oak tree will help control, prevent, and get rid of any caterpillars.

If you are looking for Bacillus thuringiensis, you can try out this product, Monterey LG6332 Bacillus Thuringiensis Worm & Caterpillar Insecticide.

6. Remove The Caterpillars Off Your Oak Tree

One of the first things you can try to get rid of caterpillars is to pick them off. I know, chills. But, If you are noticing more than usual, it may be time to take some action, and if you’re really not sure what to do first – this may be just the thing.

Now, before we get into it, we reccomend contacting a professional to inspect (and remove) the oak tree for the specific type of caterpillar on your tree. At the end of this article we review some of the common types that you may have on your oak tree.

Either with a pair of gloves and your hand, or even if you need to use a stick or branch to lift the caterpillars, move the caterpillars off the branch and tree and place them far away from your oak tree.

You may need a ladder to reach high up spots as well. However, this will ultimately help your issue, plus it will protect the caterpillars if done carefully.

Another way to do this would be to cut the branches you see the caterpillar is on and then place the branch away from the tree. There is a good chance the caterpillars will stay on the branch and will not need the tree.

5. Spray The Oak Tree With Dish Soap and Water

Another alternative method that you can try rather than using the two sprays above is by mixing just dish soap and water into a bottle and spraying it onto the affected area.

Dish soap will not kill the caterpillars, but it will make the leaves and tree too slippery for the caterpillar to stay attached and feed on. Dish soap and water are a great preventative to deter caterpillars away from your oak trees.

Whether you already have a caterpillar problem, or you are trying to prevent one from happening – spraying dish soap along the bottom trunks of your trees and on the branches can help solve the caterpillar problem before it even starts.

4. Make a Garlic and Hot Pepper Caterpillar Insecticide

Another natural way to deter caterpillars is by making your own garlic and hot pepper insecticide and spraying it around your oak trees.

A mixture of garlic and hot pepper (cayenne pepper or hot sauce), oil, dish soap, and water can be mixed together and sprayed onto your oak trees. This mix will deter caterpillars and other insects because it is strong smelling and will overwhelm the senses of the insects, making it an unsafe spot for them to feed and cocoon.

This mix will not kill any caterpillars but make your oak trees a no trespassing zone for caterpillars and other pests.

3. Plant Caterpillar Repellent Plants Near Your Oak Tree

A way to prevent caterpillars altogether is to get ahead of the problem – and plant caterpillar repellent plants nearby your oak trees.

Especially if you have newly planted or young trees, a great way to prevent a caterpillar infestation is to protect your trees from caterpillars altogether. Planting plants like Mugwort, Sage, Lavender, Mint, and Wormwood around your trees – can really help stop caterpillars in their tracks!

All of these plants are natural insect repellents and pest repellents and will not only help your caterpillar problem but other pest problems in general.

When planting these plants, just make sure to create a wide barrier around your trees, but far enough away so that your oak tree isn’t competing with these plants for nutrients. If the oak tree is young, it is important to maintain good health for the tree by allowing it to have the ample amount of water, air, and nutrients it needs to survive.

2. Add Duct Tape to The Trunk of Your Oak Tree

Another great way to prevent caterpillars from even getting up into your oak tree business is by wrapping portions of your oak trees with duct tape and the branches.

Duct tape will make the branches and trunks of the oak trees slippery – which will be a complete no, no for caterpillars and for butterflies and moths to lay their eggs on.

Although this may not be full-proof, duct tape can definitely help slow down any caterpillar infestation and will definitely help with prevention.

Just make sure not to duct tape where leaves are forming – as that will cut the air supply and can do more harm to your tree than good. 

1. Attract Natural Predators Like Birds to Your Oak Tree

Okay, this may seem out of sorts – but it actually can be a very effective way to get rid of your caterpillar problem.

Birds love to eat caterpillars, and as sad as it may be to see the caterpillars go, you will be feeding the wildlife and will be saving your tree so that it can stay strong and tall for wildlife to live in.

Attracting birds to your oak trees can be as easy as hanging a bird feeder from one or two of the branches. If there is anything a bird loves more than seeds – it’s caterpillars. So attracting them to the affected trees can be a way to get rid of the caterpillars altogether.

This is actually my favorite method because genuinely, you can install a birdhouse on or near your oak tree and boom. Over time it will work and you get to attract beautiful bird to your home.

What Types of Caterpillars Live on Oak Trees?

There are four common types of caterpillars that may be living on your oak trees, and all of the methods above, or a combination of a few, may be used to get rid of these types of caterpillars.

Pink-Striped Oakworm Caterpillars

Pin-Striped Oakworm Caterpillars are hairless, with a bigger head and smaller yellow to green body. When this caterpillar matures – it starts to turn black.

Pink-Striped Oakworm Caterpillars love to feed on oak tree leaves, especially the newly sprouted ones. They will eat the leaves until the veins and will eventually consume the entirety of the foliage.

Oakworm Caterpillars can damage entire oak tree canopies – so if you notice these bugs, it’s good to get rid of them as soon as possible.

Above is an image of what the Pink-Striped Oakworm Moth will turn into. Unfortunately, the females will continue to lay more offspring in the moth stage, most likely in your oak tree.

Yellow-Necked Caterpillar

The most easily recognizable caterpillar to its name, the Yellow-Necked Caterpillar, is yellow with black stripes.

This late summer and early fall, emerging Yellow-Necked Caterpillars will eat the leaves down to its veins. They will eat until they are nice and plump, and ready to cocoon. The caterpillars will chomp at each section of an oak tree’s leaves and will continue with this eating pattern until they eat the entire canopy!

If you start to notice branches’ leaves disappear – there’s a good possibility that you have a Yellow-Necked Caterpillar infestation – and it’s time to act fast.

Tent Caterpillar

A hairy caterpillar with a reddish-brown body, and smaller head, Tent Caterpillars are known for making tent-like webs.

Tent Caterpillars show up early in the spring and will create spooky, silky, spider-like webs that almost mimic a tent or large cocoon. Their webs are made to protect the caterpillars and to keep them from falling off high branches in your oak trees.

If you happen to see a web and want it removed, make sure to call a professional – as the webs can house hundreds of caterpillars.

Leafroller Caterpillar

The Leafroller is a smaller caterpillar with a darker-colored head and a green or brown body. These caterpillars also make silky webs like Tent Caterpillars, but the difference is – they roll leaves into their webs!

Leafroller Caterpillars will form large webs around large sections of oak tree leaves so that they can feed on them safely within their web. If these webs get out of hand, they can defoliate the entirety of the oak tree canopy.

That’s a Wrap!

Although cute from a distance, caterpillars can be one of the most harmful pests to your oak trees. They love to eat the oak tree’s foliage and can eat the entirety of the canopy if given a chance to.

When the leaves of the tree are eaten, the lack of leaves can actually stunt the growth of the oak tree and can, in turn, make your oak tree unhealthy or eventually kill it.

Oak trees need leaves, as well as all trees because it is their main source of making food. Without their leaves, oak trees may not survive.

To get rid of the caterpillars, there are many simple things that you can try that will not harm you or the trees, and the best way to avoid a caterpillar infestation – is to prevent it from happening in the first place.

With an endless supply available from healthy oak trees, acorns symbolize prosperity and youthfulness – and it’s no wonder why they’ve become a go-to symbol of fall days to come. Acorns may be the first step in growing a 100-foot oak tree, but that’s not all you can use them for! 

In truth, fallen acorns are incredibly versatile. You can use acorns in arts and crafts, animal feeders, decorations, tablescapes, and even in recipes! You can grow an oak tree from an acorn, donate them to zoos and wildlife preserves, or use them in recipes as flour, coffee, or just plain roasted.

So without further adieu – grab those fall acorns, and let’s get going, because today, we are going to talk about 10 amazing fallen acorn uses and what to do with them! 

What Are Acorns?

Oak nuts, or commonly referred to as acorns, are the fruit of an oak tree. These little acorns are actually called fruits because they contain seeds and develop from the flower. 

Oak trees contain both female and male flowers, and when the flowers reproduce – they create an acorn. Oak trees can produce up to 1,000 acorns in a month’s time and 1,000,000 in a lifetime (sometimes even 10,000,000 for rare oak trees.) 

All oak trees make acorns, but it takes them at least 20 years to be able to develop them. It takes a Red Oak Tree two full years to make an acorn and a White Oak Tree one year to make an acorn. 

These fascinating little acorns provide nutrition to wildlife, and even today and in ancient times, to humans! An acorn itself is considered a superfood, especially for our wildlife. An acorn produces carbohydrates, fats, and proteins – all of which can provide nutrients to our wildlife.

Acorns also come in varieties. The acorns of a White Oak Tree are actually sweet, and the acorns of a Red Oak Tree are bitter.

Most animals prefer the White Oak Tree acorn’s taste when given a choice, but Red Oak Tree acorns become a necessary means of survival, as even though they may not taste so good to some animals – they are nutrient-dense. When food is scarce, both white and red acorns can keep animals alive. 

But let’s be real for a second here, when acorns are fallen in a forest, there really isn’t much you need to do – but when acorns are falling all over your property, they can be a hassle. 

Throwing out acorns can be disheartening, especially when you know how much it takes for one little acorn to come to life – so next time you find yourself cleaning up acorns, skip the trash can because there are a ton of things you can do with acorns instead! 

9 Amazing Fallen Acorn Uses

From crafting, to planting, to cooking, to donating – acorns have so many uses. Being that the prime acorn falling season is from early to late Fall, the time is now to grab those acorns and do something amazing with them! 

Use Acorns in Arts and Crafts

One of the best ways to give homage to acorns is to craft with them. Little kids love acorns, and whether you want to make some after-school crafts, or even if you’re a teacher and want some free crafting supplies if you just want to make something special for yourself – acorns are a great crafting material.

Small enough and with abundance, you can glue acorns to wooden frames, paint the acorns itself and add string to make little ornaments for the holidays, or for now, or you can string them together to make acorn garland, or you can even take the caps of acorns and fill them with candle wax and a wick to make little acorn tea-light candles! 

The thing with crafting with acorns is that the ideas are limitless, and the more creative you are with your acorn crafts, the better. Acorns can be added to almost any fall craft! 

Grow an Oak Tree From an Acorn 

Besides just using them to create something else, you can also use acorns for one of their intended purposes – to grow an oak tree.

To grow an oak tree from an acorn, there are a few steps to take: 

1. Collect your acorns – preferably in the Fall.
   
2. Remove the Cap of the Acorn – the cap is like a protective covering to the seed inside the shell. 
   
3. Do a Float Test – place your collected acorns in water, and if the acorn floats, it’s a quick way to tell that it is no good! It’s important to understand that not all acorns grow into an oak tree. Also, get rid of any soft-to-the-touch acorns. 
   
4. Refrigerate the Acorns – after picking out the good ones, put them all into a plastic bag, and make them hibernate. The cool air will mimic the naturally cold conditions that occur outside – which will help them germinate. 
   
5. Once you see them germinate, or after 40-45 days, plant the acorn in a pot! 
   
6. Once you start to see a sapling – it’s time to plant your acorn into the location you want to grow an oak tree.
   
7. Make sure to water your new oak seedling!

Use Acorns in Animal Feeders 

If you have an abundance of acorns, a great way to use them would be to collect them and use them in animal feeders!

Squirrels, birds, turkeys, rabbits, and almost 100 other varieties of wildlife love acorns, and acorns are a staple part of their diet. If you have acorns that you need to pick up and get rid of (rather than throwing them in the trash), fill your animal feeders and help supply our wildlife with something to eat! 

Filling animal feeders with acorns can help you and your outdoor spaces in a few ways.

If you are having any sort of animal issue in your outdoor space, a quick way to direct the animals elsewhere would be to have a feeder – this way; they aren’t scurrying through your gardens and plants to find food.  

A feeder can also keep animals in trees and branches and away from your lawns or too close to the house. 

Donate Acorns to Zoos and Wildlife Preserves

If feeders aren’t for you and you are getting rid of your acorns, consider donating them to a zoo or wildlife preservation center. 

Acorns are free food for so many animals – and they really do love them! Before you get rid of the acorns, consider bringing them to a zoo or wildlife preservation so the animals can be fed an extra-special acorn treat!

On the plus side, even if the zoo does not decide to feed the acorns to the animals, they can also use them in community classes. Think arts and crafts, educational purposes, etc.

Donate Acorns to Organizations 

For crafts and educational purposes – donating acorns to organizations like Girl Scouts or Boy Scouts, Parks and Recreation groups, or even schools or other educational services can be a great way to use those fallen acorns.

Especially in the month of October and November, acorns are plentiful, and since they are great free materials for arts and crafts, you can try donating them to an organization or educational program! 

If you’re a teacher yourself or know a teacher – ask them if they’d like the extra acorns for a class project! It’s nice to put some of nature’s finest attributes to good use! 

Sell Acorns Online or at Farmers Markets

Believe it or not, you can actually sell your acorns on online shopping platforms.

There is actually an acorn selling market out there – and people will buy them if they need them.

Although oak trees are common in many parts of the USA, not everyone has an oak tree, and if they do, not everyone has an oak tree that is mature enough to make acorns. People actually use acorns for cooking, crafting, or even, if they want to grow an oak tree themselves, and will buy them!

Many hunters actually use acorns as bait – and will buy acorns in bulk for that specific reason. 

Use Acorns as Decorations

Another great way to use acorns is to decorate your house with them and use acorns as decorations!

If you have some decorative vases around your home, or even glass votives and candle holders, filling your home decor with acorns can be the perfect touch for Fall! It is an easy and free way to add those authentic-fall small touches around your home to welcome the chilly season!

Fall is an amazing season, and we love to make our homes feel cozy for it. Sometimes, all it takes to welcome the cozy weather into your home is to bring the outside in – and add real and natural touches to your indoor spaces. 

Make a Fall Acorn Tablescape

Continuing with the decorating tips – you can use acorns for your tablescapes this Fall.

Whether you’re hosting Thanksgiving or have your dining room tables decorated for Fall, using acorns almost like confetti laid out on your tables – can help make the perfect fall tablescape. 

A lot of times, you may have a table runner on your table, and it seems to be missing that extra touch – adding some acorns into the mix can be just the thing you need! 

Roast Fallen Oak Acorns 

Acorns can never be eaten raw; however, roasting them is a whole other story. The first step to using acorns in cooking is to first leach them. 

The leaching process consists of first shelling the acorns and then placing the seeds in boiling water. Once the water gets brown, drain out the water and add new water. Keep repeating the process until the water is completely clear. When the water is clear – then you know they are ready to be used in cooking! 

How to Clean Up Acorns Outdoors 

Now that we’ve shared all the amazing ways you can use fallen acorns – the most important thing that we have to discuss is how to collect acorns in the first place!

Depending on the number of acorns you need to clean up will decide the best tool. Of course, you can always go in with your hands to collect a few – but if you have more than one matured oak tree, there’s a good chance you can have upwards of one thousand acorns, and in this case, it’s probably easier to use a tool meant to pick up acorns! 

If you have a few acorn-making oak trees on your property, you can try the Garden Weasel, which is a tool that rolls and requires no bending whatsoever! The tool will suck the acorns up and any other small objects just by simply rolling them. 

If you have a ton of acorns and have a lot of mature oak trees around, you may opt for something more commercial like the Bag-A-Nut 12 inch Small Acorn Harvester.

That’s a Wrap! 

Acorns are one of the world’s most amazing and tiniest creations. All the things that have to go right to make one single acorn, and all the time that is needed, is absolutely amazing to think about. 

The fact that we often just get rid of acorns can be disheartening since they do so much for our wildlife and can even be used by us in many ways as well! 

Whether you are a crafter, want to take care of wildlife, want to cook, or even if you want to make some extra money – fallen acorns have so many amazing uses that we hope you try! 

Did you know that acorns aren’t the only tree that produces unusual fruits? You can read more about the trees that have acorns and what to do with them here.

The mighty oak tree is one of the most well-known and sought-after trees for the yard. They provide shade for backyard barbecues, shelter, and food for woodland critters, and some turn beautiful colors in the fall. But what about the downsides of an oak tree? In what different ways can oak trees cause damage?

Some of the ways oak trees can cause damage include cracking foundations and sidewalks, causing damage to powerlines, attracting lightning, and causing damage to roofing. Mature oak trees over 20 years old are likely to cause the most damage due to their height and the length of their root systems.

Read on to find out all the different ways that oak trees can cause damage. We’ll also talk about some ways you can prevent or mitigate this damage so you can enjoy your stately oak tree for years to come!

Ways That Oak Trees Can Cause Damage

Let’s jump right into it! Oak trees can be wonderful to have in your yard. They’re often pretty to look at, tall, and the perfect centerpiece for your landscaping.

But sometimes, oak trees can cause damage to your home, and you won’t even know it until it’s too late. You don’t actually have to have an oak tree in your yard for it to cause damage.

If you live in an urban environment and your neighbor or the park nearby has an oak tree, there could be trouble lurking below. 

Let’s take a look at the different ways oak trees can cause damage.

Damage To Sidewalks and Foundations

If you’ve ever walked down the sidewalk in a neighborhood or city, you’ve probably noticed some cracks and flaws in the sidewalk.

There are many reasons that a sidewalk might crack: the soil might simply settle and cause cracks, water may erode the concrete, or the sidewalk may have been put over the wrong type of soil (clay or sand, for example).

Another reason that sidewalks crack? Roots. Roots are an essential part of the tree, but because you can’t see them, they’re often forgotten about.

Most tree root systems are located 6-18 inches beneath the surface. This is just deep enough to remain unseen but shallow enough to cause problems above.

As the tree grows, so does its root system. The roots will continue to push outward in the soil, searching for nutrients and water sources to supply the rest of the tree. As the roots reach out to new soil, they can sometimes push into sidewalks and foundations.

How to Prevent Oak Tree Damage to Sidewalks and Foundations

To prevent roots from damaging sidewalks or foundations, you can purchase something like DeepRoot Tree Root Barriers. These come in a variety of sizes to fit any size tree. This product encourages roots to grow downward instead of outward, decreasing the chance of them damaging sidewalks and foundations.

A quick side note, while oak trees do cause damage, they are also great for the planet. You can read more about how oak trees are amazing for the environment here.

Falling Trees Can Damage Homes & Power Lines

This one may seem obvious. Of course, falling trees can damage homes and power lines, right? The problem with oak trees is that they are large trees compared to some other species, and they are susceptible to certain diseases that can cause them to topple over prematurely.

Some oak trees like the Laurel Oak, Red Oak, and Water Oak can grow up to 100’ at full maturity. That’s a big tree! 

As you can imagine, it would take a heck of a storm to knock such a massive tree over. But storms aren’t all you need to be worried about with toppling trees. Just like people, trees can become sick too. Pathogens and disease can affect oak trees, making the trunk and branches weak. 

Oak wilt, for example, will start on one branch of an oak tree but quickly spreads to the rest of the tree. Eventually, this disease will cause the tree to die, making its branches (or even the whole tree) more susceptible to falling.

One study from Environmental Management found that in a single county, the cost of removing oak trees affected by oak wilt was estimated to be in the wheelhouse of $18-$60 million over a decade-long period!

One of the biggest problems with oak tree diseases is that they can actually spread to other trees. When oaks are establishing their roots, if they are growing next to the same type of tree, they may graft their roots together for better survival chances.

If you’re interested, you can read about the most common oak tree diseases here.

The merging of these roots means that as soon as one tree is sick, the other is likely to contract the same illness. Some insects and other pests can also spread these pathogens. 

An oak tree cannot choose where and when it falls, and sometimes rooftops and powerlines happen to be in the path.

How to Prevent Oak Trees From Damaging Home & Power Lines

If you are planting an oak tree or building a house near an oak tree, be sure to give yourself enough space and try to realize its eventual mature height—at least 20 feet. Pruning is usually not necessary for oak trees, but if you notice any wilting or damaged leaves, try to prune them to contain any sicknesses. 

If you’re sure the tree is dead or dying, don’t wait to remove it! Get it done as soon as possible to prevent further damage from falling limbs.

Oak Tree Shade Can Prevent Other Plant Growth

Oak trees are known for providing tons of shade. In some instances, such as coastal live oaks, the trees may grow wider than they are tall, providing a wide area of shade.

Unfortunately for sun-loving plants, thriving next to an oak tree can be nearly impossible. If the grass isn’t already established under an oak tree, it can be tough to try to establish growth. And forget about planting any full-sun annuals at the base of an oak tree!

How to Encourage Plant Growth Near Oak Trees

If you’ve got a green thumb and you’re crafty with landscaping, you may be thinking of planting pretty flowers in some mulch at the base of your oak tree. Or maybe your oak tree throws some shade over your beautiful flowerbed.

No need to fret! There’s plenty of shade annuals you can plant that are still colorful and attractive, even without the sunshine! Many types of impatiens and begonias thrive in partial- to full-shade and come in a variety of colors.

If you’re having trouble establishing grass beneath your oak tree, try planting some shade-tolerant grass-like Scotts Turf Builder Grass Seed Dense Shade Mix. This particular mix can grow in as little as 3 hours of sun per day. 

Be sure to pick the seed that’s right for your growing zone. This mix will only grow in transition zones.

Oak Trees Can Attract Lightning Strikes

Have you ever been told never to stand under a tree during a lightning storm? It’s for a good reason! Lightning tends to strike the tallest thing in the area, and, as we said before, oak trees can grow pretty tall.

If you’re inside your house and far away from any oak trees, you may be safe from the lightning, but your water pipes and electrical control boxes are not.

Remember how we mentioned before that oak tree roots grow to try to find as many nutrients and water as possible? Occasionally, roots will find their way into the water line or sewer system.

This can be a problem, especially when oak trees are the most popular tree for lightning strikes, according to Iowa State University. In fact, oak trees were struck by lightning about 200 more times than the next most popular lightning rod tree, the poplar tree.

Besides the damage from falling debris and possible fires that are caused by lightning striking trees, we have to consider where all that energy goes after it strikes the tree: Into the roots.

If a tree’s root system is touching or wrapped around a water line, the escaping energy can cause the water line to burst. Additionally, the electricity may ride along the water line until it reaches a control box and damages those too.

Trees touching or wrapped around sewer lines can cause similar problems that often require costly repairs and can leave homes without water for extended periods.

All in all, NOT the best situation to be in.

What to Do If Your Oak Tree Is Struck by Lightning

If your oak tree has been struck by lightning, assess the damage. If the damage is only to one side, the chances of the tree recovering are pretty good. You can prune the good side of the tree to help balance the tree out, but it’s a good idea to wait a few weeks to make sure the tree will recover.

Sometimes a tree that is struck by lightning will not show any outward damage aboveground. However, below the surface, the roots may have been damaged. If you notice leaves are beginning to die off and fall off the tree, watch the progress closely. The tree may recover, but if no new leaves form in the spring, the tree is probably not recoverable.

Our last tip is to help your tree recover faster by watering it and using fertilizer. This will help reduce the stress on the tree to find nutrients and recover from its wound. Healthy oaks do not need watering or fertilizer, but it’s a good practice for injured oaks.

Additionally, if you’re finding your tree roots are causing a mess underneath the ground, you can actually use vinegar to remove the tree roots.

Oaks Cause Yard Litter

Oak trees grow from acorns, and when the trees mature enough, they begin producing their own acorns.

The number of acorns produced from a single oak tree can vary widely from year to year. Some years there can be thousands of acorns in your yard from a single tree; other times, only a few. 

Nonetheless, acorns and fallen twigs and branches can damage your lawn by covering the grass and creating unpleasant aesthetics.

This one may not bother you as much, especially if you enjoy watching little critters scurrying around your yard. But, if you live in a homeowner’s association, keeping up with the yard litter can be trying.

Preventing Oak Tree Yard Litter

Unfortunately, it’s hard to prevent trees from dropping their acorns! You can prevent some of the smaller twigs that are cut by squirrels by deterring those pesky critters before they make your oak tree their home.

Are Oak Trees Bad For Houses?

Now that all the downsides of an oak tree are laid out, you may be having second thoughts about planting one in your yard. 

So, are oak trees bad for the home?

Oak trees are not bad for houses. All trees come with their own pros and cons. Ash and poplar trees are often cited as causing damage to home foundations, just like the mighty oak. Similarly, willow and elm trees are often susceptible to lightning strikes.

It’s all about what you want in a tree. If you’re looking for a large shade tree that’s going to be around for decades or centuries, the oak tree is a great choice! But there’s nothing wrong with a maple tree, with its distinctive leaves and helicopter-like fruits that float through the air each spring.

How far Away From A House Should An Oak Tree Be?

Oak trees in the yard provide several benefits to the homeowner. They improve the scenery, are constant yet ever-changing throughout each season, and most importantly, they provide shade, shelter, and privacy to the homeowner.

The placement of the oak tree in relation to the home is important. 

To provide the best shade and maximize its use, planting a tree in the southwest corner of the house is the best location, according to the University of Missouri.

In terms of distance from the house, large trees should be planted at least 20 feet from your home and no less than 5 feet from any sidewalk. You should also make sure that the tree does not hang over your house or any often-used walkways.

Additionally, we wrote a guide on if whether or not you should plant an oak tree in your backyard.

Are Oak Trees Bad For Grass?

Oak trees are known for providing tons of shade on a hot summer day, but not all grasses are okay with growing in the shade. Will an oak tree kill your grass?

It can be difficult to establish grass beneath an oak tree if it is fully mature. Many natural types of grass need at least partial sun to grow properly and photosynthesize. However, not all grasses need tons of sunlight.

As we mentioned before, there is grass seed out there that can work with as little as 3 hours of sun per day. 

If grass is already established beneath your oak tree, try lifting your mower deck a little higher when cutting the grass within the tree’s spread (shade). Leaving the grass a little higher will help it reach any available sunlight.

Another problem with grass and oak trees is the competition for nutrients. When an oak is first growing, grass can sometimes out-compete the tiny tree for nutrients. But when a mighty oak is established, the tables will turn, and the grass can find itself scrambling to get enough nutrients.

It’s not a great idea to try to fertilize the grass as this can actually hurt an established oak tree. The best solution is to keep the grass a little higher than normal and let it thrive on its own. If it doesn’t seem to be working, try using a shade-tolerant grass seed instead.

Wrapping Things Up

Having oak trees in your yard and landscape can have tons of benefits for your home. It can frame your house, provide shade to lower utility bills, raise the value of your property, and be a nice-looking piece in your yard.

But oak trees can also create problems for your home. To recap, some of the ways that oak trees can cause damage include:

• Cracking the foundation of your home
• Cracking sidewalks 
• Falling branches and trees can damage roofs 
• Falling branches and trees can damage power lines nearby
• Oak trees can prevent sun-loving plants from growing
• Damage to waterlines via roots or lightning strikes
• Fire damage due to lightning strikes
• Sewer line damage due to roots or lightning strikes
• Yard litter from acorns and snipped branches

You can prevent or minimize the damage done by oak trees by knowing all the different ways they can cause damage and being prepared for each one.

Hopefully, after reading this article, you have a better understanding of all the different ways oak trees can cause damage, and how to prevent it so you can enjoy these lovely trees for years to come.
