I know it is late, but I finally moved the last peony to the new spot ... made just for them. No overhanging trees branches to make them unhappy. The last one I will move this year. The root system was enormous and there was a whole world of little living things living right there in the system. Big worms, rolly pollies, many spiders ... all scrambling in their world to be safe. I moved most of them out of the way. But it is really amazing to see. Now if all the peonies I moved this fall will survive. Keeping my fingers crossed.
