Question From: C. Demler - Weidman, Michigan, United States
Q: Nancy, my wisteria vine, trumphet vines and one climbing rose bush all have a white powdery mold on them. The leaves are all falling off the wisteria and the leaves on the trumpet vine and rose bush are deformed and curling up looking like they are dying. Can you tell me what this maybe and how to get rid of it?
A: Your plants have powdery mildew. It's a fungal disease. Be sure to clean up the area around the plants this fall. You will probably need to treat the plants in late spring, I prefer a product called Actinovate. Follow the package directions. It is not a silver bullet and you will probably have to spray every two weeks. Best And Happy Yardening, Nancy
