My bee balm was thriving and enjoying all the rain for awhile. But now the combination of way too much rain and chronically high humidity have resulted in it having a bad case of powdery mildew. Bee balm is susceptible to it anyway, but the conditions haven't helped.
I think it's too advanced for any treatments I am willing to use in my garden to help it. What do you think about just cutting it all down to ground level? I would do that in the fall anyway.
