Seed propagation
The plant produces seeds that can be collected when they are mature and sown immediately in a well-draining potting mix. The seeds need to be planted at a depth of about 2 cm and watered regularly. Germination usually occurs within 2-3 weeks. Seed propagation is an easy and viable method of propagation.
Cuttings propagation
Cyphostemma hispidiflorum can also be propagated by stem cuttings. Select healthy stems that are about 10-15 cm long and free from diseases and pests. Remove the leaves from the bottom half of the stem and dip the cut end in a rooting hormone. Plant the cutting in a well-draining potting mix and water it. Keep the soil moist and place the pot in a warm and shaded area. Rooting usually occurs within a few weeks.
Air-layering propagation
Air-layering is another propagation technique that can be used for Cyphostemma hispidiflorum. Select a healthy stem and strip off a ring of bark about 3-5 cm wide from the middle of the stem.
