Cover the seeds about ¼ inch deep and keep them in a shaded area. Within a few weeks, the seedlings should appear.
Stem Cutting Propagation
Stem cuttings can be taken from a mature plant during the early growth period. The length of the cutting should be around 6 inches, and it should have at least one node. Remove the leaves from the lower half of the stem and dip it in rooting hormone before planting. The soil mix for the stem cutting should be well-draining and moist. Plant the cutting in the soil and keep it in a shaded area. Keep the soil moist, and within a few weeks, the plant should start to root and grow.
