When planting a Tree Peony, be sure to bury the graft union (appearing as a bulge on the main stem) 1.5 inches below the soil surface to protect it from freezing/thawing cycles. This will help to maintain a healthy, reliably blooming plant. In northern regions, the graft should be planted even deeper. An annual topping of compost is recommended each Fall. Though peonies may be slow to establish, you can be assured that they are developing a deep, substantial root system which will help to produce flowers that are well worth the wait. Once established, Peonies can live 50 years or more.
