The Q&A Archives: How do I control powdery mildew on my dogwood?
Question: I have a recently planted, young pink dogwood tree that has a case of powdery mildew. I followed advice I found online, planting it in full sun, making sure the branches were aerated, etc., but the problem seems to be worsening. What fungicide should I use, and when is the best time to apply? I know the fungu won't kill the tree, but it is an ornamental, and I want it to look its best!
