Preparing the Soil

Tree peony and herbaceous peony like loamy and loose soil with good drainage content to a depth of at least 2 feet. Best avoide uncultivated or clay or saline earth and poor drainage. The bad soil should be improved to good soil. The nicer potted soil is also loose, fertile, well-aerated and well-drained. They grow best in soil with a PH of 6.5 to 7.5.

Planting Tree Peony

Space your peony plants at least 120cm (about 4 feet) apart. Tree peony roots grow 100cm to 150cm (about 3 to 5 feet) into the ground. When planting, the hole should be large and deep with ample room to accommodate all the peony roots. In general, the depth of the hole should be about 45cm (18 inches) deep and the opening 45cm (18 inches) in diameter. Build a soil cone to support the peony roots and make sure that the roots are fully extended. With one hand holding the plant and the other fill the hole little by little using prepared soil, hand-pressing to remove any air pockets and to stabilize the peony plant. The correct planting depth is with the root collar the same level as or slightly below the earth surface. Firm the ground gently and water it thoroughly after filling the hole. It is very important to keep the ground warm. So the new peony roots can develop even in late fall or in winter. In a warm climate, mulch your new plant with leaves, pine straw, or such type of material. In cold climate, the whole plant needs to be covered for winter. The material needs to be 15cm (about 6 inches) over the top of the plant.
