When you wish to grow a beautiful Japanese maple tree in your yard or garden, a question might arise in your mind: do deer eat maple trees?
Yes, it’s a matter of concern as no one wants their precious tree to be damaged anyway, right?
Since these trees are sometimes sold, said to be deer resistant, it makes people curious to learn the truth from a trusted source.
I have a few varieties of Japanese maple in my backyard, so I have had experience with these trees for a long time.
Therefore, I can help you learn the answer to the question: are Japanese maples deer resistant or edible?
Now, without any further ado, let’s find the answer.
Do Deer Eat Japanese Maples Or Not?
As soon as the spring season starts, Japanese maples turn into an excellent source of food for many animals.
But what about deer!
Among the hundreds of species, deer appear to love the forage of Sugar and Red maples the most. But, the thin branches and changing burgundy leaves of Japanese maples don’t seem to be a deer’s favorite.
Wait, wait, there’s a twist!
Deer aren’t picky eaters. Especially during winter, when foods are rare than in any other season, they eat any plant, including Japanese maple, if they can’t find anything better.
Generally, deer prefer those trees that bear fruits and nuts.
They mostly eat the moss, leaves, and branches during spring and summer, but they eat the bark or the fallen seeds in the fall and winter seasons.
Yet, experts couldn’t identify an exact pattern between favorites as it varies from season to season. They may love a tree in summer but hate it in winter.
Now, the question is, by any chance, can the Japanese maple be deer resistant.
Let’s know the answer in the next segment.
So, Can Japanese Maples Be Resistant to Deer?
No, not exactly. Even if the tree is sold as deer-resistant, there’s a chance that deer will damage your maple.
Deer-resistant plants are those that deer won’t choose to eat if there is a better option available.
Remember that Japanese maples aren’t deer’s first priority.
However, newly planted and young Japanese maples are the most vulnerable to deer predation, especially by curious fawns that are looking for new food sources. They love the heavily fertilized young shoots.
Deer will chew the fresh leaves, which is enough for a young tree to defoliate. Also, they will try to get their hooves on your precious maple tree’s lowest tender branches.
I have both young and established maples in my yard, and only the young ones were the target of deer once. The older ones were left unharmed by them.
So, I can say that they are mostly after the young maples.
But, recently, I came to know the fact that deer can damage older maple trees too but not by eating them down. They love the shade of the maple trees and sometimes spend time rubbing their antlers and forehead against the tree trunk.
This act can also cause significant damage to the tree, which could eventually kill it.
By the way, since there are different types of Japanese maples, from dwarf to tall ones, you may wonder if there are any deer-resistant varieties available.
Therefore I have arranged a segment below to describe whether they are resistant or not, depending on different species.
Different Varieties of Maple Trees And Their Resistance Ability to Deer
First, I will explain whether deer eat dwarf Japanese maple, a popular species that gardeners choose to grow.
1. Dwarf Japanese Maples
Native to Japan, Acer palmatum (dwarf Japanese maple) aren’t a favorite meal of deer. It’s not common to see deer eating these maples, but it can happen.
The size of the dwarf maple, which is also known as Wilson’s Pink Dwarf, can be appealing to deer as they can easily access these trees. They only grow 2 to 4 feet tall, and that’s why deer won’t even need to jump or struggle to reach their branches or higher young branches.
In short, dwarf Japanese maples can be damaged by deer more than any other maple variety because of their reachable size.
2. Autumn Blaze Maple
Okay, be prepared to read the whole thing cause I am gonna share some important information.
First of all, autumn blaze maple is sold, saying that they are resistant to deer.
And it’s mostly true!
These trees attract bees but not deer. Also, their leaves are toxic if eaten.
Here comes the exception. Suppose a deer is excessively hungry and there is no other food option around, as well as it doesn’t know that these trees aren’t for eating; it may end up damaging your young autumn blaze maple tree, not the grown one.
But it’s pretty rare to happen. And once the deers learn that these trees aren’t edible for them, they will never attack them again.
3. Crimson Queen Japanese Maple
Crimson Queen is a low-branching dwarf tree that has a delicate and weeping form. Because of their low height, deer can easily access the shoots.
So, yes, there is a high possibility that your local deer will eat the maple’s buds during the winter season.
4. Aconitifolium (Full Moon Maple)
Earlier, I mentioned that the deer attacked my maple trees only once.
So, here it is. A deer ate a couple of branches from my newly planted Aconitifolium. After buying this tree, I grew it in a pot for the first year.
And then I planted it late last winter. Shortly thereafter, a deer came and took some bites from this tree.
However, they haven’t bothered my Japanese maples since then. Hence, I guess that deer was looking for food in the cold winter and ended up damaging my tree without knowing its taste.
Shortly, Acontifolium is deer-resistant but not proof. And when any of the maple trees are young, you have to take care of them.
Therefore, I will guide you on how to keep deer away from your maple trees.
Learn How to Protect Japanese Maple from Deer
There are several ways of protecting your plant from deer. And the very first one is installing a fence.
1. Install Fence Around The Plant Area
Setting up a fence is one of the most reliable ways to keep deer away from your tree. Usually, deer won’t go through much trouble just to get their food unless needed.
You may not consider it an aesthetic solution, but it’s definitely the most effective one.
You can get a chicken or heavy wire fence around but far away from the tree. This obstacle will make them struggle and search for food somewhere else.
Remember that your fence should be at least 8 feet tall and not have gaps bigger than 6×6 inches.
Moreover, fencing around your Japanese maple tree will also protect your tree from deer rubbing.
2. Protective Netting
Another way of plant protection from deer is using plastic or mesh netting around the young maple tree. The wire netting you will use must be strong enough to prevent deer from pushing on it.
You can also consider using chicken wire cages. However, make sure to keep enough space for your maples to grow so that you don’t have to change them now and then.
3. Planting Plants at The Outer Part of the Garden That Deer Dislike
You may plant things that deer don’t like to eat on the outer side of your garden. This method will reduce the chances of the deer entering inside.
Generally, deer don’t like toxic, highly fragrant, or prickly plants. Trees like rosemary, large lavenders, and fragrant herbs effectively discourage deer from entering your garden.
You may plant a deer resistant viburnum, such as arrowwood viburnum, which deer don’t like at all.
Aside from growing fragrant plants, it’s also a good idea to choose ones that are a little taller to decrease visibility into your garden, which may contain more appealing plants.
I have several Thuja Green Giant, which is a fast growing deer resistant tree. As they grow pretty tall and provide almost no visibility inside, you can also choose to plant these on the outer part of your garden.
On the contrary, it’s always best to plant anything they may like to eat near your house since your day-to-day activities will somewhat limit their access to the garden.
4. Deer Repellent
Odor deterrents can keep deer away from the gardens. There are several options available in the market, but I will suggest you buy those that don’t contain too many chemicals.
After all, we don’t want to harm the innocent animal or our tree, right?
Well, you can also try a homemade repellent such as garlic or rotten fish heads, fabric softener, etc.
However, these kinds of solutions need constant usage as the effect will last only a few days. Studies show that the most effective deer repellents work only for about 10 to 12 weeks before the deer become accustomed to the smell and continue their normal feeding habits.
So, I recommend that you purchase at least two different types of deer repellents that can be used alternating throughout the year to lower the chances of the deer becoming acclimatized to the scent.
You may consider buying “Deer Out” and “Plantskydd,” as they are made from various types of ingredients and have a distinct scent.
5. Mechanical Repellent
Mechanical repellents also come in a range of many forms, such as ultrasonic devices and motion-activated sprinkler systems. Another device that is also effective is called predator eyes, which mimic the appearance of a predator’s eyes at night.
The motion-activated sprinkler is the most efficient one among all of these devices. But, just like the chemical repellents, deer can become habituated to these systems too.
Therefore, you need to regularly move the sprinklers’ position and occasionally turn them on and off to ensure that the deer don’t become accustomed to their presence.
6. Frightening Sounds
Deer can be easily scared by sounds. You can use an object with high-pitched sounds like whistles, wind chimes, radios, or electric wires.
So far, you have come to know some methods of how to keep deer away from trees. But, what are you gonna do if a deer already ate or damaged your Japanese maple trees?
Don’t worry. I will also provide a guideline on this matter.
Take a look at the following segment.
Direction on What to Do If Deer Ate Or Damaged Your Japanese Maple
First of all, don’t be too concerned about your Japanese maples. They are quite resistant to deer, and even when damaged, they make it through and survive most of the time.
Still, if you suspect that deer have harmed your tree, follow the below methods to identify and take the necessary steps.
1. Evaluate The Damage
The first thing you’ve to do is to examine the damage. Sometimes, the damage is caused by an insect or an illness rather than by deer. So, inspect the leaves.
If a deer eats your tree, the leaves will most likely be chewed whole or in halves, and the stems will be left untouched. On the other hand, most insects will eat only the corners of the leaves or make holes in them.
After being assured that deer cause the damage, the next phase will be determined by how badly the leaves, bark, or roots have been harmed.
Trees will most likely recover from any harm, but they may require some assistance.
2. Remove Them
You shouldn’t be concerned if the deer left some buds behind.
Remove the chewed areas of the leaves. They will turn brown and die anyway and eventually recover naturally. Trim damaged branches if you see any and let nature do the rest of the job.
3. Protect from Further Damage
After you have taken care of the damage, you should protect your Japanese maple with a fence, chemicals, or homemade remedies, whatever protection method you prefer that I have already mentioned before.
Now besides eating, deer can also cause damage by rubbing themselves against the tree.
Male deer replace their old antlers with new velvet-coated antlers as the warm seasons begin.
This coat will dry out and begin to itch by fall. So deer will need to scrape it off, which they will most likely do by rubbing against tree bark. And the damage to some trunks can be irreversible.
If the damage is not severe, it may take a few years, but the tree will survive and recover from its wounds.
But, sometimes, the tree will die or become so fragile that it eventually will break off.
By the way, deer aren’t the only threat to your Japanese maple trees. And I think you should know about which other animal causes harm to this beautiful tree.
Other Animals That Eat Japanese Maples
Actually, the cute deers aren’t the main villain that attacks the maple trees. As you know, they are less likely to harm these trees.
You should be concerned more about mice, rabbits, and voles that eat the bark and can be pretty destructive. Squirrels enjoy chewing or pruning Japanese maples with their teeth, and they often break the branches off to mark their territory.
Insects are another threat. And one of the renowned pests is the Japanese beetle which is a culprit in creating problems for maples and cherry trees.
There is a shiny green beetle that loves to eat Acer platinum. These bugs come in the summer and can be a nightmare since they consume large groupings of leaves, leaving only the skeleton behind. They also nibble at the tree roots, decreasing water flow.
Do Deer Eat Regular Maple Trees? (Not Japanese Ones}
Yes, there are some maple species that are loved by deer.
Silver maple, sugar maple, and red maple are the top favorite meals for deer among all the maple tree varieties.
And the Japanese varieties are something that deer choose when there is a lack of food.
Okay, as I am at the edge of my writing, it’s time to say goodbye.
Now tell me, are Japanese maples deer resistant?
Hopefully, you got your desired answer with some other necessary information.
In short, the taste of Japanese maples isn’t preferred by deer. Only the exception will occur based on the population of the deer and their extreme hunger during the dry season.
A hungry deer might quickly develop a liking for a tree that previously appeared to be resistant.
As I again make the fact clear, now I will sign off from this topic.
