Japanese Maple Diseases
Japanese maple trees are a highly favored variety among homeowners for many different reasons.
They are fairly easy to grow and maintain, if they are planted properly and on a sufficient watering schedule.
They come in many different varieties of heights and colors.
They can adapt to smaller spaces where other specimen might fall short.
Usually any issues that arise are due to maintenance, as they are pretty disease resistant.
However, no tree is completely disease free and are susceptible to certain types of pests. We’ve listed a few of the most common pests and diseases that typically attack Japanese Maple trees.
Verticillium Wilt
This is a soil born fungi that is usually brought on by environmental stressors such as drought, frost or wet soil. The most common symptom of verticillium wilt is branch die back. We recommend regular maintenance pruning of all trees, but especially if dead limbs are present. Other treatment options might be available to you by a local tree arborist.
Anthracnose
Anthracnose is another type of fungal disease that not only attacks Japanese Maple trees, but a large variety of other trees and shrubs as well. This is most commonly seen during rainy seasons or areas with high humidity. Symptoms of anthracnose on Japanese Maple trees are spots or scorch on the leaves. Performing regular tree trimming and removing all infected leaves are good practices to avoid and treat this disease.
Phytophthora Root Rot
Japanese maple trees have never adapted well to over watering. They are highly susceptible to root rot because they have a low tolerance to soil that does not drain well. Proper planting and maintaining a watering regimen specific to Japanese Maple tree is the best treatment.
Japanese Maple Scale
Scale insects such as the armored scale favor the Japanese Maple tree under stress. If your Japanese Maple tree is not getting enough water, has suffered an injury or is under any other type of environmental stress, this can be an open invitation to scale insects to attack. These insects are usually seen on the bark and sometimes can be manually removed with soapy water. We recommend consulting a local certified arborist if you notice any pests on your trees.
