September is the best time to move your peonies to a new location or to divide established plants.
The most common way to establish trees in the home landscape is to purchase balled and burlapped or container-grown plants at local garden centers and nurseries. Balled and burlapped (B&B) trees are dug with balls of soil around their roots. The rootballs are wrapped in burlap and held in place with twine or nails. Large trees are placed in wire baskets for additional support. Balled and burlapped trees can be successfully planted from spring to fall.
