Crepe Myrtle Has White Cotton Substance On Leaves And Has Not Bloomed For Two Years

Question From: Mesquite, Texas, United States
Q: Hi Nancy, My Black Diamond Crepe Myrtle (Red Crimsom) has white snow fungus and white cotton substance on a few leaves. It has not bloomed for 2 years now. I noticed the leaves are blooming well on most branches but a few branches are dry. It is very small but it is trying to overcome. What should I use to help it thrive and grow and bloom beautifully again? Need your advice...Thank You. Sincerely, Yolanda

A: Your crepe myrtle has fungus called powdery mildew. Poor circulation around the tree, lack of water = drought stress and excessive fertilizing are all causes. Thining out side branches over time and regular watering will help. They do not need fertilizing after the first year. Visit your local garden center for a fungicide will work on this shrub. Best And Happy Yardening, Nancy
