I just transplanted Bart. Boy was that tough to get out of the ground. It was in competition with a hydrangea that was much smaller when they were planted several feet from each other. I ended up getting three separate plants out of it. One larger and two smaller ones. It's actually A lot easier to go in at that 45+ degree angle as compared to straight down because you would end up digging a huge hole ! Even after a trim of roots. Dividing peonies, not a favorite pastime of mine.
