Planting & Care

Choose a location with full to partial sun and dig a planting hole twice as wide as the root ball but equally deep. Backfill with well-draining soil, water thoroughly to settle, and apply mulch around the base to retain moisture. Water only during extended dry periods—check soil moisture 3 inches down before watering. Light pruning in winter removes dead wood; additional pruning is optional for shaping. Balanced fertilizer in early spring supports young trees, but fertilizing becomes unnecessary once fruit production begins.
