Dahlia Problem: Powdery Mildew
Powdery Mildew (PM) is a problem for some varieties of Dahlias. There should be no negative affects outside of the aesthetics on Dhalias; however, if vegetables susceptible to PM are nearby, it is advisable to treat all plants to help minimize spread. Planting Dahlias in Direct Sunlight with ample space for good air circulation between plants will help limit PM. PM is not caused by overhead watering. Fungicides will also work if you're not concerned with organic requirements.
