text: When planting tree peonies it is recommended that you plant the graft union (where tree peony is grafted on to nurse root) a good 10 to 12 inched below the soil line so that the nurse root will not send out shoots, but will in fact, help the tree peony establish it's own root system and then the nurse root will die off and the tree peonies own root will take over and sustain the plant.
