Planting & Care

Select a location receiving at least six hours of direct sunlight and prepare a planting hole twice as wide as the root ball. Position the plant so the top of the root ball sits level with the soil surface, then backfill and water thoroughly. During establishment, maintain consistent moisture, then transition to supplemental watering only during extended dry periods. In early spring, apply a balanced slow-release fertilizer to encourage blooming, and prune lightly in late winter to remove dead wood and shape as desired.
