Why are branches dying on my Japanese maple?

Why are branches dying on my Japanese maple?

Japanese maples hate “wet feet,” so a combination of poor drainage and rain like we had in May can encourage a soil-borne fungal disease called phytophthora. This disease can kill trees branch by branch.

Why does my maple tree have dead branches?

The dying branches could be caused by a girdling root. Work with an arborist to use an air spade to remove the soil around the base of the tree to look for a girdling root. Another potential cause of dying branches: phytophthora root rot. This widespread soil pathogen causes problems among landscape plants.

How do you know when a Japanese maple is dying?

Cut a small sliver of bark from the individual limb that appears dead with a knife, or from the trunk of the tree if the whole tree is in decline. If the wood under the bark is tinged green, the tissue is still alive and will likely recover. If the wood is tan or dry, that part of the tree is dead.

Why are some of my tree branches dying?

It could be that the tree isn’t getting enough sunlight due to thickness, so it will thin itself out for that reason. Other times, it won’t get enough water so it self thins to preserve the healthiest branches. In other cases, a fungus or disease can cause a tree to self thin, according to Science Direct.

What causes dead branches on a tree?

EAB causes trees to decline because they feed on the vascular tissue and restrict water movement in the tree. Damage to the vascular system causes wilting and branch dieback in the tops of the trees or at branch tips inward. The inner branches of all trees will decline and die as the tree matures.

Should you remove dead branches from trees?

Diseased, dead and broken branches should be removed right away. Pruning for shape isn’t necessary until the first winter after planting. Regular pruning throughout the life of a tree reduces the amount of work necessary and the stress on the tree.
