leaf wilt - fungicide?
One of the three peonies I put in last fall has over the last few (very wet rainy) weeks had leaves wilt. There are usually one or two lower leaves wilting on the plant every day or two when I check it. I cut off the affected leaves and discard them. The other two plants within 10 foot of this one don't show this problem. Is this due to the overly wet conditions? What can I do? Do I needa a fungicide if so which one?
