Has anyone used this for indoor begonias? I thought I read somewhere that someone used it successfully for PM on their indoor begonia, but the bottle says not to use for potted plants.

I had a black magic that got a bad case of powdery mildew. It was a lost cause and I trashed it because even the props developed it. Now I desperately want to protect other cane begonias!

Any advice is appreciated.
