Site Selection

Ninebark grows best in acidic, well-drained soil in full sun to partial shade, but is adaptable to many soil conditions.

Planting Instructions

Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the pot the plant is in. Carefully remove the plant from its container and place it in the hole so the top of the root ball is level with the soil surface. Carefully fill in around the root ball and firm the soil gently. Water thoroughly.

Care

Water regularly until established. After it's established, ninebark is drought-tolerant. You can propagate from hardwood cuttings. Established shrubs require annual pruning to maintain their shape. Prune early each spring by removing some of the oldest branches by cutting them off at the base. Do not ingest this plant, as all parts of the ninebark are known to be poisonous.
