Propagation of Crassula barbata Thunb. subsp. barbata
Crassula barbata Thunb. subsp. barbata can be propagated by various methods such as:
Leaf Cutting Propagation
The most common and successful way to propagate Crassula barbata Thunb. subsp. barbata is through leaf cuttings. Cut a healthy leaf with a sharp, sterilized knife from the mother plant. Let the cut end dry for a day or two until it has calloused or hardened to prevent infections. Then place it on top of a well-draining soil mixture and keep it in bright, indirect light. Water the soil occasionally to keep it slightly moist until roots and new leaves have grown.
Stem Cutting Propagation
Another propagation method is through stem cuttings. Cut a stem about 3-4 inches long from the mother plant with a sterilized knife. Let the cut end dry for a day or two until it has calloused or hardened to prevent infections. Then plant it in well-draining soil mixture and keep it in bright, indirect light. Water the soil occasionally to keep it slightly moist.
Offsets Propagation
Crassula barbata Thunb. subsp. barbata also naturally produces new shoots or offsets, which can be separated from the mother plant and be planted in a new container. Use a sharp, sterilized knife to carefully remove the offset. Allow it to air dry for a couple of days, until the cut callouses over, and then plant it in a well-draining soil mixture.
Propagation of Crassula barbata Thunb. subsp. barbata can be done anytime in the growing season, which is typically from spring to early summer. With proper care and attention, the plant can grow quickly from cuttings or offsets, and can flower within a year.
Disease and Pest Management for Crassula barbata Thunb. subsp. barbata

To prevent root rot, ensure that the soil is well-draining and do not overwater the plant. If the plant is already affected by root rot, remove it from the soil and cut off the affected roots before repotting it in fresh and well-draining soil.
Another disease that may affect Crassula barbata Thunb. subsp. barbata is powdery mildew. This fungal disease appears as a white powdery substance on the leaves, and it can cause them to become distorted and die. To prevent powdery mildew, ensure that the plant has good air circulation, and avoid wetting the leaves during watering. In case the plant is already affected, remove the infected parts of the plant and dispose of them properly. Also, you can use fungicides to eliminate powdery mildew.
Common Pests
While Crassula barbata Thunb. subsp. barbata is generally resistant to pests, it can be affected by some of them. One of the most common pests that may affect this plant is mealybugs. These pests appear as small, white, fluffy insects on the leaves of the plant and can cause significant damage.
