Plant sempervivum in well-drained soil, such as rocky or gravelly soil or a porous potting soil. Sempervivum grow best in full sun, although they will tolerate partial shade.
Water sempervivum about once a month, letting the soil dry out between watering. Provide more water in the summer than winter, but don't over water or plants may develop rust or crown rot.
Fertilize sempervivum very lightly during the growing months. Use about 1/4 of the amount recommended on a houseplant fertilizer label and fertilize no more than three or four times a year.
