Planting & Care

Select a location receiving at least partial sunlight, though this shrub adapts equally well to shaded spots. Dig a planting hole twice the width and depth of the root ball, position the plant at the same soil level it was growing in, and backfill with native soil before watering thoroughly. Apply a 2–3 inch mulch layer to conserve soil moisture and regulate temperature. Water regularly during the first growing season to establish a strong root system. Once established, maintain moderate watering during growing periods and increase frequency during heat waves or drought. Apply balanced slow-release fertilizer in early spring if desired, and prune immediately after flowering finishes to remove dead wood or reshape the plant as needed.
