Planting & Care

Plant within four weeks of arrival in a location receiving full sun or partial shade with well-draining soil. Dig a hole twice as wide as the root ball and plant at the same depth as in its container. Water deeply during the first year to establish a strong root system, then reduce watering as the plant becomes drought-tolerant. In late fall or early spring, cut foliage back to ground level to promote vigorous new growth. This plant rarely needs fertilizer, but you may apply a slow-release formula in early spring if desired.
