Is My Crepe Myrtle Tree Diseased?
Crepe Myrtle Disease Trunk
To determine if your crepe myrtle is diseased, you can look for certain signs and symptoms that may indicate a problem. Here are some common indicators to watch for:
Leaf Discoloration: Check for unusual discoloration on the leaves, such as yellowing, browning, or spotting. This can be a sign of various diseases affecting crepe myrtles.
Leaf Spotting: Look for the presence of spots or lesions on the leaves. Fungal diseases like Cercospora leaf spot or powdery mildew can cause characteristic spots or powdery patches on the foliage.
Leaf Deformities: Examine the leaves for deformities or abnormalities like curling, cupping, or distortion. Certain pests or diseases can cause these changes in the leaf structure.
Powdery Coating: A powdery white or grayish substance on the leaves, stems, or buds may indicate powdery mildew, a common fungal infection affecting crepe myrtles.
Bark Issues: Inspect the bark for any signs of cracking, splitting, peeling, or discoloration. These symptoms may indicate a disease or physical damage to the tree.
Twig Dieback: Look for branches or twigs that appear dead, with no leaves or signs of new growth. This can be a result of disease or environmental stress.
Abnormal Growth Patterns: Observe the overall growth pattern of the tree. If you notice stunted growth, excessive wilting, or lack of vigor compared to other crepe myrtles in the vicinity, it could be a sign of an underlying issue.
It's important to note that some symptoms, like leaf discoloration, can also be caused by factors such as inadequate watering, nutrient deficiencies, or environmental stress. If you suspect that your crepe myrtle is diseased, it's recommended to consult with a certified arborist, horticulturist, or local extension service for a proper diagnosis and guidance on appropriate treatment options. They can provide specific recommendations based on the particular disease affecting your crepe myrtle and suggest the best course of action to restore its health.

How do I care for my crepe myrtle tree?
Proper planting
First and foremost, ensuring soil pH is slightly acidic and well draining will give you the best results. Not sure what type of soil you have? Local certified arborists can take a soil sample from the area you would like to plant to give you an inside look on what you may need to supplement with. Plant your crepe myrtle in full sun (6 hours or more per day) to get the best blooms!
Fertilization
We recommend having a tree care specialist apply a fertilizer to your soil to keep your crepe myrtle healthy and thriving.

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.
