Propagation methods for Triainolepis africana Hook.f. subsp. africana
Triainolepis africana Hook.f. subsp. africana is a perennial plant that can be propagated both sexually and asexually. Here are some of the most common propagation methods:
Seed propagation
The seeds of Triainolepis africana Hook.f. subsp. africana can be collected from mature fruits. The fruits should be harvested when they turn brown and start to split open.

Cuttings
The plant can be propagated by stem cuttings taken in spring or summer. Use a clean and sharp knife to cut a stem of about 10-15 cm from the parent plant. Remove the lower leaves and dip the cut end of the stem in rooting hormone. Plant the stem in a well-draining potting mix, and keep it moist and warm. The cutting should root in about 4-6 weeks, and can be transplanted into the garden once it has established roots.
