Echeveria vs Sempervivum: Propagation
Propagating Echeveria and Sempervivum is an easy and rewarding process. Both succulent types can be propagated through stem or leaf cuttings. For stem cuttings, take a healthy stem from the mother plant and let it dry out for a day or two to callus over before planting it in well-draining soil. For leaf cuttings, remove a healthy leaf from the mother plant and let it dry out for a day or two before placing it on top of the soil mix. After a few weeks, roots will start to grow from the base of the leaf and a new rosette will emerge.

Sempervivum, being monocarpic, produce offsets or “chicks” from the mother plant that can be gently pulled apart and replanted in separate pots. These offsets grow into new plants that will eventually flower and produce their own chicks. Echeveria, on the other hand, are not monocarpic and will continue to produce rosettes indefinitely, making them an excellent choice for propagation through division. Simply divide a healthy rosette from the mother plant and replant it in well-draining soil.
