Remove dried or dead leaves immediately to prevent pests and other issues.
Propagation of Cotyledon Sulphurea Toelken
Cotyledon sulphurea Toelken can be propagated through several methods, including leaf cuttings, stem cuttings, and seeds.
Propagation through leaf cuttings:
Leaf cuttings are a simple and effective way to propagate Cotyledon sulphurea Toelken. Select healthy and mature leaves from the parent plant and cut them cleanly near the base. Place the cuttings on a dry surface and let them dry for a few days. Once the cuttings have formed a callus, plant them in well-draining soil and water sparingly until new growth appears.
Propagation through stem cuttings:
Stem cuttings can also be used to propagate Cotyledon sulphurea Toelken. Cut a healthy stem from the parent plant and let it dry for a few days. Dip the cut end of the stem in rooting hormone and plant it in well-draining soil. Water the cutting sparingly until new growth appears.
Propagation through seeds:
Cotyledon sulphurea Toelken can also be propagated through seeds. Sow the seeds in well-draining soil and cover lightly with soil. Keep the soil moist until the seeds germinate, which can take up to two weeks. Once the seeds have germinated, water the seedlings sparingly until they are established.
Regardless of the propagation method used, it is important to keep the new plants in a warm and well-lit area while they establish roots and begin to grow.
