Sempervivums are known as alpine succulents, as they are native to the mountains of the Mediterranean and Europe. They grow in an array of sizes and colors and require little care once established. Like their desert-grown counterparts, most of these succulents require a sunny growing area to produce their most brilliant color and are ideal for inclusion in a rock garden. Sempervivums are monocarpic plants; they will die after flowering.
Grow the sempervivum in sandy soil. Use equal parts of soil and sand. This will provide the drainage necessary to keep the plant's roots from remaining too moist.
Water the sempervivum only when the soil is completely dry. Do not water at all during the winter.
Fertilize the sempervivum monthly from April through September. Use a fertilizer formulated for succulents and apply it at the rate suggested by the manufacturer. Always water the plant before fertilizing.
Remove dead plants and fill the area with sand if you will not be planting a replacement.
