Plant Sapphire Tuffet SunSparkler® Sedum in well-drained soil with full sun exposure. Space plants about 12-18 inches apart. Water regularly during the first growing season to establish a deep, extensive root system. Once established, reduce watering as the plant is drought-tolerant. Fertilize lightly in spring with a balanced, slow-release fertilizer. Prune in early spring to remove dead stems and encourage new growth.
