Planting & Care

Select a spot with partial to full shade and acidic, well-draining soil. Dig a planting hole twice the width of the root ball and set the plant so the top of the root ball is level with the ground. Backfill with soil, water thoroughly, and apply mulch to conserve moisture and protect shallow roots. Keep the soil consistently moist during the first growing season and during dry periods. Fertilize in early spring with an acid-loving plant fertilizer, and deadhead spent flowers after blooming to encourage next year's flower production. Light shaping in late spring will maintain the plant's attractive form.
