How to Propagate Sedum clavatum
It’s very easy to propagate Sedum clavatum from leaves, cuttings, or seed.
You can easily propagate the leaves of Sedums by choosing a firm, healthy leaf. Remove it from the main plant by gently twisting the leaf from the stem. Be sure not to leave any of the leaf on the stem (if you take a bit of the stem with the leaf, that’s fine, too!).
Allow the leaf to callous over for several days, and then lay on well-draining soil. Water whenever the soil has dried completely. After roots and a rosette have appeared, and the mother leaf has withered away, plant the new growth.
To take a cutting of a Sedum clavatum, use a sharp, sterile knife or pair of scissors. Cut the stem away from the Sedum cluster, and allow the cut to callous over for a few days before planting in well-draining soil.
If propagating from seed, sow in a well-draining soil in the fall. You can grow Sedum seeds outdoors if you live in an zone above 9a. If you live in a cooler area, you can begin sowing indoors under a grow light.
