Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. After the first killing frost, cut stems back to an inch or two above soil line. Divide plants every 3 to 4 years as new growth begins in the spring, lifting plants and dividing them into clumps.

There are numerous types of sedum, all of which have fleshy, succulent leaves. Low-growing varieties hug the ground and may reach just 2 inches in height, while tall varieties top out at 2 feet or more. Use the low-growing types as ground covers and in rock gardens; tall varieties command attention in the perennial border with their dense foliage and large flower heads. Flower colors include red, pink, gold, yellow, and white, and plants bloom in summer to fall, depending on the species. Well-drained soil is essential to ward off fungal diseases, especially during wet summers.
