Powdery Mildew on SquashI am not really very experienced, but I got a lot of powdery mildew on all my squash plants this year. We live in the Denver, Colorado area. I just let the leaves die off, then picked them and cleared them out of the garden. By then there were a lot of fresh new leaves that took over. I think it helped to get the sun in there from picking the dying leaves. My plants did great after that. The fruit was good and all. I just harvested a 55 lb pumpkin, and have had many other varieties that did great too. The mildew did not return. I guess I was just lucky.
