Q.Mold on Pine Bushes
Last summer/fall I struggled with powdery mildew on my pine bushes. I did treat them with a fungicide. It is only the middle of March and it looks like the powdery mildew survived the winter and is still a problem. I live in Eastern PA. Is that possible? Should I treat them again now?

Yes, treat the now to help stop it before it really sets in. I would also consider if it would be possible to do a little pruning to open up the plant just a bit to improve air circulation and help keep the mildew away.
