Unlike many other fungal diseases, powdery mildew thrives in warm, dry climates, though it does require fairly high relative humidity (i.e., humidity around the plant) to spread.In cooler, rainy areas, it does not spread as well. In some cases, if the infection is severe enough, powdery mildew can kill your plants.
Powdery Mildew is most problematic in shady, humid, areas with poor air circulation, so give your plants good air circulation (provide support for climbing varieties is important). Remove infected leaves to reduce the spread. The fungal spores overwinter on plant debris, so clean up the beds in fall. Also make sure the plants are well fed and ...
