Leaves. If the leaves on the Japanese maple tree dry, curl or look scorched around the edges, it may not mean the tree is dying. It could indicate that the tree is not getting enough water. If the dead leaves drop from the tree, the tree could still be healthy.

People also ask, what would cause a Japanese maple to die?

Most plant problems give you at least some warning, but Japanese maples (and to some degree other maples) can die pretty quickly from a wilt disease called Verticillium. That would be my first guess based on your description. The fungus that causes the disease can get in the soil.

One may also ask, how often do you water a Japanese maple tree? Water every 2-3 days for the first month. After that, a good watering once a week should be sufficient, but monitor it often as windy days can dry out soil quickly. If the tree is fall planted, water once a week when no rain or snow cover is provided. Tip 2 Always provide a layer of mulch around Japanese maple trees.

In this way, why is my Japanese maple turning brown?

Usually brown spots appear because the leaves got wet when the sun was out and that can cause a small burn on a leaf with a droplet of water on the leaf. Brown edges can be a sign of a tree that de-hydrated. Now if all of the leaves on your Japanese maple are turning brown and falling off, you have a serious problem.

How do you revive a dying Japanese maple tree?

Check the soil drainage around the Japanese maple. Dig a 6-inch deep hole 2 feet from the trunk. Pour a few cups of water into the hole. If water is still standing in the hole 15 minutes later, the tree may be dying from root rot.

Severe cold in late spring, after plant tissues have swollen, can cause bark to crack, split and fall away.

Prune away all damaged branches and stems, and continue routine tree care through the growing season.
