Germination usually takes between 2-4 weeks.
Cutting Propagation
Another way to propagate Cryptolepis angolensis is through stem cuttings. Take a stem cutting 3-4 inches in length, and make sure it has a few leaves attached at the top. Plant the cutting in a pot filled with moist soil and place it in a warm, shaded area. Keep the soil moist and in a few weeks, the cutting will start to develop roots and new growth.
Division Propagation
Propagation of the Cryptolepis angolensis can also be done by division. Established plants can be dug up and carefully divided into smaller sections, each with their own roots. Replant the divisions into moist soil, and place them in a shaded area with high humidity to promote root growth.
Overall, Cryptolepis angolensis is an easy-to-propagate plant, and any of these methods should provide you with successful propagation. It is important to keep the soil moist and provide a humid environment to promote growth.
