I have white mildew looking powder on one of my Beuford holley bushes. What is this and how can I get rid of it before it spreads. |
Alice, Hollies are not normally prone to powdery mildew. It could be residue from minerals in irrigation water. I suggest you take some leaves to your County Extension Office for them to examine and diagnose. Then they can make suggestions for dealing with the problem. Thanks for the question. Please stop in again soon! |
