DIVISION OF A PEONY PLANT
In September, dig your peony carefully, taking care of keeping all the roots. Cut all the foliage keeping only 4 inches of stem. Wash the peony roots with a soft water jet. This will ensure that all the eyes and the crown will be clearly visible. Be careful not to damage eyes on the crown.
Put your plant on a stable work table, well cleaned. Watch carefully the whole plant. Eliminate all the damaged or rotted parts. Each peony division should have at least 3 to 5 eyes on the crown. Determine how many divisions you will be able to do in counting the number of eyes and how the roots crown system is organized. Keeping this standard division with 3 to 5 eyes will greatly help the survival of your plant even if one or two eyes are damaged by frost or manipulation during the plantation. For the general gardener, bigger divisions could be made i.e. with dozen of eyes. That's even better!
