| My monarda has powdery mildew. Although I thinned the monarda in the spring and it's not at all crowded, the hot humid weather we're having right now seems to have gotten to it anyhow.
I have a couple questions:
1) What do I do? Do I just cut it all down and hope that contains the infection? I don't have to remove the plants entirely, do I?
2) I have some garden phlox ('David') nearby. (What I was thinking when I put two powdery mildew susceptible plants side by side I'll never know.) Will the powdery mildew spread to the phlox? It looks so pretty right now I'd hate to see that happen. How can I prevent it from spreading?
Any advice is welcome. This is the first year I've ever had powdery mildew. |
