Planting & Care

Plant in full sun with well-draining soil in a location that receives at least 6–8 hours of daily sunlight. For in-ground planting, dig a hole matching the size of the root ball; for containers, choose a pot roughly twice the width of the shipped container. Water young plants once or twice weekly, checking soil moisture 2–3 inches deep. Each spring, apply a balanced fertilizer to encourage vigorous growth and blooming. Pruning is optional—only prune to maintain a specific shape for hedging or to manage overall height.
