My pulmonaria has developed a powdery mildew. Any suggestions on treatment or prevention?
pulmonaria problem
Good air circulation helps, after the powdery mildew is eradicated.
cut it way back and it will come again ...
I agree about cutting it back. This often happens if the area is too densely planted or it could be just dryness at the roots. Cut off the affected leaves and it will sprout again.
just read that this powdery mildew may be caused by too dry soil. That may be my problem.
thanks for your input.
