Expert Response
It's ok to burn garden waste affected by powdery mildew if burning is allowed in your locale. Otherwise, dispose of it at a municipal yard waste disposal site. Do not compost at home.
According to authorities at Colorado State University, powdery mildew fungi overwinter on plant debris, not hard surfaces.
