To prevent powdery mildew, plant disease-resistant varieties and make sure there is good air circulation around your plants. Water early in the day so leaves don’t remain wet overnight.
Once it’s established there’s not much you can do, but if you spray the leaves at the first sign of any mildew, you can slow it down.
