Sedum is a large genus of flowering succulent plants in various sizes from low ground covers to small shrubs. According to the USDA Plant Database there are 52 known species and many cultivars. Like many succulents, sedum can be divided vegetatively and the divisions can be planted to root into new identical individual plants. The rose-shaped and symmetrical plantlets that sedums develop readily make attractive new plants. The University of Missouri recommends harvesting and rooting sedum rosettes in the spring or summer for optimal results.
Snap or cut the sedum rosette off of the parent plant, leaving roughly 1 or 2 inches of stem attached below the rosette.
Wet the cut end of the stem with water and dip into rooting hormone powder to help encourage fast root development.
Fill a nursery pot four-fifths of the way up with a sterile, lightweight and slightly alkaline potting medium, firming it gently. Create a hole in the soil with a pencil to accept the stem cutting.
Slide the hormone-covered stem cutting into the soil and firm the soil around the stem. Water in gently to make the surrounding soil evenly moist but not soaking wet. Keep the soil evenly moist until the sedum is well rooted in the pot.
