Propagation by stem cuttings
Stem cuttings are another popular way to propagate Eberlanzia horrescens var. densa. To propagate using this method, take a stem cutting that is at least 3 inches long, and let it dry out for several days. Dip the cut end in rooting hormone and plant it in a container with well-draining soil, like cactus and succulent mix. Place the container in a bright location with indirect sunlight. The soil needs to be moist, so water it sparingly. The new plant will root in 4 to 6 weeks, after which it can be transplanted to its permanent location.
Whether you choose to propagate Eberlanzia horrescens var. densa by seed or stem cuttings, both methods are relatively simple and can be successful with proper care and attention.
