Could someone please tell me what to do with the foliage of peonies after flowering. They look tattier as the year progresses and as far as I can see people just leave them until late winter to cut back before the new shoots come up. What is the reason for this? Are they left for winter protection? Would it be detrimental to the plant to cut them off in Autumn?
