Propagation of Crassula sarcocaulis Eckl. & Zeyh. var. scaberula Harv.
Propagation of Crassula sarcocaulis Eckl. & Zeyh. var. scaberula Harv. can be accomplished through various methods:
Stem Cuttings
Stem cuttings are the easiest and most common method of propagating Crassula sarcocaulis Eckl. & Zeyh. var. scaberula Harv. Cut a stem from the main plant and let it dry in the shade for a couple of days. Once it has calloused, plant the stem in well-draining soil in a container. Water every 4-5 days and keep the container in a sunny place. Roots will start to develop within a few weeks.
Leaf Cuttings
Leaf cuttings can also be used to propagate Crassula sarcocaulis Eckl. & Zeyh. var. scaberula Harv. Choose a healthy leaf and gently remove it from the plant. Allow it to dry in a shaded place for a couple of days until a callus forms. Plant the cutting in well-draining soil and keep it in a spot with indirect sunlight. Water it lightly every 4-5 days and be patient. You should soon see roots emerge from the base of the cutting, followed by the growth of a new plant.
Offsets
Offsets, or plantlets, can be produced by the mother plant and subsequently propagated. These small plants grow alongside the base of the parent plant and can be gently removed, being careful not to damage the roots. They can be potted in well-draining soil and placed in a warm, sunny location where they can flourish.
