Propagation of Vitex buchananii Gürke
Vitex buchananii Gürke, commonly known as the Buchanan's sage, is a tree that belongs to the family Lamiaceae. It is native to East and Central Africa, where it grows in rocky areas and woodland margins. The tree is valued for its ornamental features, including its attractive flowers, foliage, and bark. It can be propagated through various methods, including seeds, cuttings, and air layering.
Seed Propagation
Seed propagation is one of the most common methods used to propagate Vitex buchananii. The seeds are collected from mature fruits and cleaned of any debris. They should then be sown in seed trays filled with a well-draining medium, such as perlite or sand. The trays should be placed in a warm and bright location, and the soil kept moist. Germination usually occurs within four weeks. The seedlings should be transplanted into individual pots once they have two to three leaves and are strong enough to handle.
Cutting Propagation
Cutting propagation involves taking stem cuttings from an established Vitex buchananii tree and planting them in a rooting medium. Ideal cuttings should be around 10-15cm in length and should include at least two nodes. The leaves on the bottom half should be removed to reduce moisture loss. The cuttings should be dipped in rooting hormone before planting in a sterile potting mix. The pot should then be covered with a plastic bag to maintain humidity. The cuttings should be kept in a warm, bright location, and the soil kept moist. Roots typically develop in around six weeks, after which the cuttings can be transplanted into individual pots.
Air Layering
Air layering involves creating a small wound on a low branch of an established tree, wrapping it in damp sphagnum moss, and covering it with plastic wrap. Over time, the wound will grow roots into the damp moss, allowing you to separate the new plant from the parent tree. This method is effective, but it can take several months for the new plant to form roots.
