Spent 2 years fighting powdery mildew in my squash patch, then figured out the dumbest fix
Same spot every summer, same white coating on the leaves. Tried neem oil, baking soda sprays, copper fungicide, all the internet tricks. Nothing stuck. Last month I just moved my squash to a new bed that gets morning sun instead of afternoon sun. Haven't seen a speck of mildew since. Been 6 weeks now. Who knew it was just about where the dang sun hits? Anyone else find a simple solution after years of overcomplicating something?
The old books were right about a lot of things, hard to beat experience like that. Morning sun dries the dew off fast and that's usually the whole trick with mildew.
