Hi all. My very, very old clumps of peonies are blooming less and less, especially one. All three are large clumps and all get full sun. I would like to dig up, divide and transplant the non-blooming one to see if it will bloom again. The buds are just coming up. Is it too late; should I wait until fall? Also, will it be apparent when I dig it up how to divide it? I read that they should be planted 2" deep. Any advice will be appreciated.
