Ninebark is part of the rose family. It is a multi-stemmed deciduous shrub that grows 6 to 10 feet tall. Ninebark has medium-green leaf color that turns yellow to bronze during fall. The flowers are whitish pink and bloom in May to June. The reddish fruit matures in September to October. Ninebark’s reddish-brown bark is subject to excessive peeling. Shrubs thrive in full sun to partial shade. It is best to transplant a ninebark shrub when it is dormant in the early spring.
Remove weeds and large rocks from the planting area. Clean up any other debris laying on the soil.
Dig the hole 18 to 24 inches wide and as deep as the ninebark's rootball. Do not plant ninebark shrubs with any of the roots exposed aboveground.
Remove the container. Tilt the shrub on its side and gently pull it out. If it does not come out of the container easily, cut the plant pot away with a sharp knife. Remove all wires, string and twine from the branches.
Place the ninebark shrub in the hole and fill the hole halfway with soil. Pour 2 gallons of water in the hole around the roots.
Fill the hole the rest of the way with soil, then gently firm the soil around the ninebark shrub. Spread 4 to 6 inches of mulch like wood chips or sawdust around the ninebark to help keep the area weed free.
