Plant Rock 'N Grow® Superstar Stonecrop in well-drained soil with full sun exposure. Space plants about 18-24 inches apart. Water regularly during the first growing season to establish a deep root system, then reduce frequency as the plant is drought-tolerant. Fertilize in early spring with a balanced, slow-release fertilizer. Prune spent flowers to encourage new blooms and maintain shape. Divide clumps every few years in early spring to promote vigorous growth.
