Sedum is a versatile, remarkable plant that can grow in the toughest of circumstances, including thin, rocky soil and punishing hot, dry weather. In spite of its toughness, sedum is an attractive plant that includes varieties for every situation, including indoors or outdoors, in the ground or in containers. Planting a leaf cutting is the easiest and most reliable way of propagating sedum.
Fill a 3- to 4-inch container with a mixture of three-quarters coarse sand and one-quarter commercial potting soil. Dampen the mixture ahead of time, using distilled water. The potting medium should be just barely moist, as sedum, like all succulent plants, will rot in excessive moisture.
Use a clean, sharp knife or a new razor blade to cut a leaf from a healthy sedum plant. Take the cutting from high on the plant, and avoid leaves at the plant's base. Set the leaf aside for four or five days, or until the broken end dries and forms a callus.
Dip the broken end of the sedum leaf in powdered rooting hormone. Set the leaf aside for four or five days, or just until the broken end scabs over and forms a callus. Don't leave the leaf so long that it begins to wilt.
Plant the leaf into the potting medium. Plant the leaf just deeply enough that the leaf stands upright.
Set the container in a warm, well-ventilated place where the leaf will be exposed to bright, indirect sunlight for at least eight hours every day.
Water the leaf cutting lightly using distilled water whenever the soil feels dry to the touch. Allow the water to run through the drainage hole and never allow the container to stand in water.
Transplant the new sedum plant when the roots are well-established, which will take several weeks. At this time, the leaf will show new growth and the original leaf will shrivel. Plant the sedum in a container filled with commercial potting soil for cactus or succulents. Be sure the container has bottom drainage.
