Site SelectionSelect a site with full sun and moist, well-drained soil.
Planting InstructionsPlant in spring or fall, spacing plants 5 to 10 feet apart, depending on the variety. 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 rootball is level with the soil surface. Carefully fill in around the rootball and firm the soil gently. Water thoroughly.
CareApply a thin layer of compost each spring, followed by a 2- to 4-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. Flowers are produced on new wood, so prune back old growth almost to the ground early each spring before any new growth emerges.
