Vitex agelaeifolia, commonly known as white horse chestnut, is a native tree species of East Africa that belongs to the family Lamiaceae. It is grown for its medicinal properties as well as for ornamental purposes. The plant can be propagated through various methods such as seeds, cuttings, and layering.
Propagation by Seeds
The easiest way to propagate Vitex agelaeifolia is through seeds. The plant produces seeds in large quantities which can be collected during the fruiting season. The seeds can be sown directly in the ground or in seed trays filled with a well-draining potting mix. The optimum temperature for germination is around 20-25°C, and the seeds usually germinate within 2-4 weeks. Once the seedlings have grown to a suitable size, they can be transplanted to their permanent locations.
Propagation by Cuttings
Vitex agelaeifolia can also be propagated by cuttings. The best time to take cuttings is during the growing season when the plant is actively producing new shoots. Select healthy stems, about 10-15 cm long, and remove the leaves from the lower part of the stem. Dip the cut end into a rooting hormone and plant in a well-draining potting mix. Place the cuttings in a warm and humid environment, preferably under a misting system or in a greenhouse. Rooting may take up to 2-3 months. Once the cuttings have developed roots, they can be transplanted to their permanent locations.
Propagation by Layering
Vitex agelaeifolia can also be propagated by layering. This method involves selecting a low-growing branch and removing the leaves from a section of the stem that is in contact with the soil. The branch is then anchored to the ground using a wire or peg and left to develop roots. Once the roots have formed, the branch can be separated from the parent plant and transplanted to its permanent location.
