Question From: S. Payne - Trenton, Ohio, United States
Q: I have gray scale on both a flowering crabapple tree and a rose of sharon tree. What can I do to treat these before losing them?
Spray for apple scab when the leaves are emerging and repeat in 7 days. One the tree has leafed out it's too late. Bayer Advanced Disease Control for Roses, Flowers and Shrubs is one of the products recommend. Clean up all dead leaves and twigs around the tree and dispose of them in the trash. The same treatment works for the rose of sharon. Best And Happy Yardening, Nancy
