I have some powdery looking leaves on my astilbe and it seems to be spreading to anything that is close to it in the bed. Does anyone know what it is and how to "fix" it?

There's quite a bit of powdery mildew on plants now. The rain and humidity are the reasons. We even have some of the fungus on native trees. Cornmeal juive and garlic sprays will work but the new Plant Wash product is probably the best solution. If you are in North Texas, astilbe is not the easiest plant to grow.
