Leaf propagation shows how resilient many succulents can be. A healthy leaf, even a small one, may produce roots and a new rosette when conditions are stable.
Choose firm leaves, remove them cleanly, and let the wound dry before placing them in a bright, airy location. Avoid burying or soaking the leaf. The parent leaf stores water while roots and new growth begin.
Not every leaf will succeed, so treat it as a patient experiment. Good light, airflow, and restraint with water make the process much more reliable.
