Can anyone throw me some ideas of using cs around outdoor plants? We live in Southwest Washington State. Many of my annuals and perinials end up with powdery mildew mid to late season. I'm curious if cs might help prevent, and if they should be watered with it or spritzed onto the plant. I thought it might help kill the moss/mildew that has grown on the deck over the winter, but so far no luck. Maybe as a preventative once the deck is cleaned, and then sprayed to let cs dry. Lin
