Albizia sassa (Willd.) Chiov. var. chirindensis (Swynn. ex Baker f.) Baker f., also known as the Chirinda albizia, is a tropical tree with a narrow crown that can reach up to 40 meters in height. It is endemic to Zimbabwe and Mozambique but can be grown in other parts of the world with similar climates. Propagation of the Chirinda albizia can be done through both sexual and asexual methods.
Propagation by Seeds
Propagation of Albizia sassa var. chirindensis can be done through seeds. The Chirinda albizia produces large, woody pods which house the seeds. To propagate through seeds, the seeds should be collected and soaked in water for about 24 hours and then sown into seed trays or directly in the field. It is important to not bury the seeds deeply but rather just press them lightly into the soil. Germination usually takes place within two to three weeks and the seedlings are usually ready for transplanting after 6 months.
Propagation by Cuttings
Propagation through cuttings is another viable method for Albizia sassa var. chirindensis. Softwood cuttings of 10-15 cm in length can be taken from the tree during the rainy season. The cuttings should be dipped into rooting hormone powder and inserted into a rooting medium. A mixture of sand, compost, and peat moss can be used as the rooting medium. The cuttings should be kept in a shaded area and watered frequently. Roots should start developing after about 4-6 weeks.
Propagation by Air Layering
Air layering is another method through which Albizia sassa var. chirindensis can be propagated. This method is best used if it is not feasible to take cuttings, or if the tree is too valuable to be damaged by cutting. This method involves girdling a branch, applying rooting hormone, and covering the area with moist soil. Roots should start growing within 4-8 weeks, and the rooted branch can then be cut from the parent plant and planted into the desired location.
Propagation of Albizia sassa var. chirindensis can be done successfully through any of these methods if the necessary precautions are taken, ensuring a beautiful and healthy tropical tree for any desired location.
