Question From: La Grange, Texas, United States
Q: My Texas Mountain Laurel has a white powdery substance over most of the leaves, plus some totally white places on some leaves. ?
A: Your tree has powdery mildew and needs to be treated with a fungicide. If this is a large tree enlist the services of a certified arborist. To find one in your area go to www.tcia.org. Be sure to clean of any fallen debris around the tree. Best And Happy Yardening, Nancy
