I recieved 4 large tree peonies today from a friend who does landscaping. He had to dig them out and asked me if I wanted them. I know it's probably not the best time to transplant, but I had to take them when they became available. They are all finished blooming, and have mature seed pods on them. I am thinking it's best to remove the seed pods, but should I cut them back? A small amount, a lot or not at all? I've never had these before. Thanks in advance for your help.
