powdery mildew - causes/control
So I've never experience powdery mildew on my cukes, zukes, and squash until this year. I don't even understand HOW I got it considering we've had a VERY LONG dry spell here in NJ this summer. Explanations?
Yesterday I decided to cut off the really badly affected leaves. I mean a lot of them. Did I effectively kill those crops or will they recover? I figured I had nothing to lose at this point and I wasn't about to spray anything (milk solutions, store products, etc) on the leaves this late into the season.
