How Deep Are Tree Peony Roots

The most critical aspect of planting peonies is correct planting depth. Grafted tree peonies should be planted so that the graft union is approximately 4-6 inches below soil level. This may leave very little of the woody stem showing above ground and the roots may need to be trimmed to fit in the pot.

How deep are peony roots?

In order to set their flower buds, peony roots should be planted relatively close to the soil surface—only about 2-to 3-inches deep.

How much space does a tree peony need?

Tree Peonies do best in a sunny to partly shady site, holding their flower colour longer if planted when morning sun provides most of the light, in average, well-drained, evenly moist garden soil high in organic matter. Space plants 3-feet apart for a hedge.
