Propagation of Vitex ferruginea Schumach. & Thonn. var. amboniensis
Vitex ferruginea Schumach. & Thonn. var. amboniensis can be propagated through different methods. Here are some common propagation methods:
Seed propagation
One easy way to propagate Vitex ferruginea Schumach. & Thonn. var. amboniensis is through seed propagation. The seeds can be collected from mature fruit capsules. It is important to note that the seeds have low viability, and germination rates can be improved by soaking the seeds in water for 24 hours before sowing. The seeds should be sown in well-draining soil in a warm and sheltered spot, and watered regularly.
Cuttings propagation
Another method of propagating Vitex ferruginea Schumach. & Thonn. var. amboniensis is through cuttings. Softwood cuttings should be taken during the growing season from the current year's growth. Cuttings should be taken from a healthy parent plant and should be about 15 cm long with at least three leaf nodes. Cut the bottom of the cutting at a 45-degree angle and dip it in a rooting hormone before inserting it into well-draining potting soil. Keep the cutting in a warm and sheltered spot with high humidity until new growth appears.
Air layering propagation
Air layering is a method of propagation that is commonly used for woody plants like Vitex ferruginea Schumach. & Thonn. var. amboniensis. In this method, a stem of the parent plant is wounded and then covered with a rooting hormone and sphagnum moss. The wound and the moss are then covered with plastic wrap, and the roots will develop in the moss. After the roots have developed, the new plant can be cut from the parent plant and planted in well-draining soil.
