The following are the methods used to propagate Vitex bequaertii De Wild.
Seed propagation
Propagation of Vitex bequaertii De Wild. can be done through seed or vegetative propagation. The seeds are obtained from mature fruits that turn black when ripe. The seeds must be soaked in water for 24 hours before sowing to enhance germination. Sow the seeds in well-draining soil and maintain a temperature of 22°C to 25°C.

Vegetative propagation
Vegetative propagation is a faster and more reliable method of propagating Vitex bequaertii De Wild. It is usually done using stem cuttings or layering.
Stem cuttings
Take stem cuttings of about 10 cm in length from a mature, healthy plant and dip them in rooting hormone. Place the cuttings in a rooting medium that is well-draining, such as sand or vermiculite. Maintain high humidity around the cuttings and keep the medium moist. Roots should develop in about 3-4 weeks, and the new plant can be transplanted to its permanent location.
Layering
Layering involves bending a low-hanging branch to the ground and burying a section of it in the soil while leaving the tip exposed. The buried section will produce roots, and when they are well established, the branch can be separated from the parent plant and transplanted.
