Dividing peonies, need suggestion..
I know the conventional wisdom is to divide peonies in September. However should I divide them this fall if I plan to dig them up again and pot them for sale next spring? (I sell at a local plant sale). I'm not sure if it's a good idea to disturb them twice. They have been in place since 1994 and have always bloomed very well so I believe they are in good health. Thanks for any advice!
