Answer #1 · John Heider's Answer · Hi Sherry-This substance you are seeing is most likely powdery mildew. Below is a link to an article by a Cooperative extension service that will show you a picture of this mildew. It will also give you some help on treating this fungal disease and preventative measures you can take. I have an older variety of crape myrtle that is very susceptible to this disease. I treat the tree using neem oil as it is safe to use in the garden not hurting my pets and beneficial insects. Just click on the link below to go directly to the article.

Please ask if you have any other questions.
