Why Is My Japanese Maple Tree Dying?

If you have a Japanese maple tree that is showing signs of dying, then this blog post will help. We are going to talk about some of the most common causes for tree death in these trees and how to prevent them. Let’s get started!

Why Is My Japanese Maple Tree Dying?

Your Japanese maple tree is dying because it is not receiving the care it needs. This usually involves being planted too deeply, receiving too much water, and suffering from a fungal infection.

Japanese maple trees can be finicky when growing in certain conditions, so that is one reason why you might have a dying tree. If your tree was planted too deep or the roots were damaged during planting, this could cause problems for the tree later on, which will make them die out after several years.

You should always ensure that you plant these trees at an appropriate depth and make sure they do get hurt during the process. This will give your tree the best chance of a long life!

I will now take an in-depth look at the different potential causes for Japanese maple tree death…

Fungal infection

This is quite common in maple trees, so take a closer look to see if your tree has some black spots on its leaves. This could be a sign that you need to treat for fungal infection and this will save your Japanese maple tree from dying!

If you see these types of symptoms start appearing, then do not hesitate by purchasing an anti-fungal solution to stop any more damage. The sooner you get started with treating fungus, the better chance that your Japanese maple tree will survive!

Too much water

It is also important that when planting new trees into your landscape, they should receive enough water, but NEVER too much water.

When the soil around these trees becomes soggy and waterlogged, it can cause root rot to develop in your Japanese maple tree.

This root rot is bad news for maple trees, especially when it happens at a young age, so make sure these trees are well-drained and do not stand in too much water.

Too little light

If your Japanese maple tree has been placed into an area that does not get any sunlight, then it might start dying out and dying.

You see, the tree needs sunlight to produce food and sugars through photosynthesis so it can grow properly. If there is not enough sunlight, then the tree will quickly weaken over time because of this issue.

If you see your Japanese maple tree starting to die out after being planted in an area that does not receive any light, then move them into a sunny location ASAP! This should help save these trees from dying!

If the light is the problem, you should move your tree into a sunnier area and see if that helps. You can also purchase artificial lighting to help give it more light than before, which should work just fine!

The tree has been planted too deep

Planting your Japanese maple tree too deeply will mean that water and other nutrients can’t be absorbed by your tree. As such, make sure only one inch of soil is on the stem of the tree. This is a mistake many new tree owners make, so be mindful when planting your new Japanese maple.


Will too much water cause my Japanese maple tree to die?

Yes, if you give your tree too much water, then it can cause root rot and this will kill the roots of your maple tree. This is a common problem that many people have when planting new trees in their landscape!

How do I treat fungal infections on my Japanese maple tree?

To treat fungal infection, you need to purchase some sort of fungicide spray or dust that goes onto the leaves as well as into the soil around where your trees are planted at. This treatment needs to be done throughout all stages of growth with these types of trees during any season they have new growth coming out!

How do I get my Japanese maple tree to be more drought tolerant?

To make them more drought-tolerant, you need to water it less often and only when the topsoil feels dry. This will help your tree become accustomed to not receiving too much water all at once which will prevent root rot from developing!

Can a dying maple tree be saved?

If you notice that your tree is dying, then it might be time to invest in a new one! If the problem has not set in too far yet and there are still leaves on the branches growing out, then maybe all it needs is some fertilizer or fungicide sprayed onto its roots which should help save it from certain death.

Is my Japanese maple tree planted too deep?

The root ball of a Japanese maple tree should be a few inches above the grade. The stem of the tree should also only be an inch or so deep. I like to create a mound of soil around the root ball, which allows water to flow away from the tree.

Why are Japanese maple tree leaves turning brown?

Brown and crispy leaves go hand in hand with a plant that hasn’t received enough water. If the leaves are brown, but wet, then you have a maple tree with root rot. Follow the tips above to fix these issues.


In conclusion, you have learned about some of the most common causes for Japanese maples trees to die out. If you take care of your tree properly, then it should last a lifetime!
