Planting & Care

Choose a location receiving full sun with well-drained soil amended with compost. Dig a planting hole twice the width of the root ball, position the plant so the crown sits at soil level, and water generously to settle the soil. Throughout the growing season, maintain evenly moist soil with approximately one inch of water weekly, reducing frequency during cooler months. Apply a balanced slow-release fertilizer in early spring and supplement with liquid fertilizer every four to six weeks during active growth. In late winter or early spring, prune away dead or weak wood and thin crowded stems to encourage an open structure and maximize flowering.
