I planted a nice 'Canary Brilliants' peony at my daughter's house in Utah 3 years ago in the fall. It's been growing and blooming beautifully and is very happy.
But . . . I know, I shouldn't complain - it's taking over the whole bed! This year it is 5ft. tall and 5ft wide according to my daughter (I'm in Florida, going to visit next week).
Can we divide the clump in the fall or next spring? How and when? Am I just messing with success here? Just prune it back after it's finished blooming?
Pictured last May when it was just starting to bloom, and it almost doubled in size this year according to my daughter.
