Propagation of Crassula diaphana Drège ex Harv.
There are several methods of propagating Crassula diaphana Drège ex Harv. for cultivators who want to propagate the plant and reproduce it.
Propagation by Leaf Cuttings
Crassula diaphana can be propagated from leaf cuttings. Leaves or part of the leaf can be cut out with a sharp and clean blade. The cutting should be left to dry in the shade for a few days until a callus forms at the base of the cutting. The cutting can then be planted in a suitable substrate and kept in a humid, warm and bright location. Within a few weeks, new plants will emerge.
Propagation by Stem Cuttings
The plant can also be propagated from stem cuttings. The process is similar to that used for leaf cuttings, but stem cuttings will usually grow into a new plant faster. The best time to take stem cuttings is in hot seasons like summer or spring.
Propagation by Offsets
Crassula diaphana can also propagate by dividing the plants into offsets. The plant will produce offsets or small baby plants which are attached to the mother plant by short stolons. The offsets can be detached by gently pulling and planted in a new location to grow the new plant.
Propagation by Seeds
Propagation by seeds can also be done, but it may take longer. The seeds must be collected from the mature plant and planted in a suitable substrate and kept in a suitable location. Germination usually takes place within a couple of weeks in warm and humid conditions.
