Leaves On Salvia Are Turning Whitish Grey

Question From: C. Ringenberg - Hillsdale, Michigan, United States
Q: The leaves on my salvia are turning a whitish gray. What is going on with them?

A: I believe your salvia has powdery mildew. Treat it with a fungicide. I prefer ACTINOVATE, an OMRI listed organic fungicide that is kind to the environment. Best And Happy Yardening, Nancy
