Hello Susan,
Typically, peonies are cut back after a hard freeze (late October to November). The stems can be cut down to within a couple inches of the ground. Sometimes, powdery mildew attacks the foliage of peonies. When this happens, the stems turn brown or black earlier. You can cut them back and dispose of the plant material before a hard freeze.
Hope this helps.
Many many thanks! I've had 3 plants, and they have all grown up under something else, so this year, I decided to move them. And the stalks have turned black. So, I think I'll cut them back soon.
Hi Susan,
I did a quick check and you are well within the time window when peony transplanting should be successful. There is no additional winter care necessary.
Happy gardening!
