Title: Small oak tree with powdery mildew in San Antonio, TX.
Answered by: Jimmy Mills


I have a small oak tree with powdery mildew. Is there anything I can do about? Will it kill the tree?

Ohio State University

Colorado State University

Although the powdery mildew is unsightly, it probably won’t kill your oak tree.
