--Mercy Otis Warren--The bee balm in our flower bed gets powdery mildew so easily... if the flower wasn't so pretty I think I would pull it up and plant something else. I tried to wash the leaves off and that didn't work so I sprayed neem oil... I just hate putting any spray out there... any ideas from the gardeners on 365?
Beautiful capture of this pretty blossom. It has such a nice vibrant red. Neem oil is the main thing I know of. My plant source says limit nitrogen fertilizer also.
