Is this powdery mildew on my Monarda Mohawk? If so is it harmful?
It hasn't done very well the last few years so I seperated the plants into smaller pots. Only one has flowered.
Thanks for info.
Def. powdery mildew, but I slightly disagree with Verdun, in that although it is unsightly, it has never caused any long term problems on my Monardas.
