White Dust on Peony Leaves
I have had the bush in my yard for about 7-8 years and the last two seasons they have had white dust on the leaves. They still bloom as usual, but lately not as much as they used to. I dont add these leaves to the compost as I am afraid it will damage what I have, and I dont want to dig them up if not necessary. I may have a picture and can post, but if someone knows what this is, please tell me how to cure and what to do!
