Planting & Care

Select a location receiving at least six to eight hours of direct sunlight daily with well-drained soil. Dig a hole sized to your plant's root ball and backfill with quality soil, pressing gently to eliminate air pockets. For container planting, choose a pot approximately twice the width of your shipped container. Water consistently one to two times weekly during the growing season, reducing frequency once the plant establishes itself. Minimal pruning is needed—simply remove dead or crossing branches in early spring to maintain shape.
