Propagation Methods of Crotalaria tsavoana Polhill
Crotalaria tsavoana Polhill is a plant that belongs to the family Fabaceae. Its common name is Tsavo rattlepod and it is an endemic plant species found in Kenya. It is a perennial shrub that is often propagated through seeds or cuttings. Here are the propagation methods for Crotalaria tsavoana Polhill:
Seed Propagation
The easiest way to propagate Crotalaria tsavoana Polhill is through seeds. The seeds should be collected when they are mature and have turned dark in color. They can then be scarified using sandpaper to break their hard seed coats. Soaking the seeds in warm water for 24 hours can also help in breaking the seed coat. After scarification, the seeds should be planted in a well-drained potting soil. The soil should be kept moist but not waterlogged, and the seeds should germinate in about 7-10 days.
Cutting Propagation
Crotalaria tsavoana Polhill can also be propagated through cuttings. Cuttings should be taken from the top of the plant and should be about 6-8 inches long. The leaves at the bottom of the cutting should be removed, leaving only 2-4 leaves at the top. The cutting should then be dipped in rooting hormone powder and planted in a well-draining soil mix. The soil should be kept moist but not waterlogged, and the cutting should sprout new roots in about 2-4 weeks.
Division Propagation
Crotalaria tsavoana Polhill can also be propagated through division. This method involves dividing the plant into smaller sections and replanting them. To propagate through division, the plant should be dug out of the ground and its root system should be carefully separated. Each section should have some healthy roots and leaves. The sections should be replanted in well-draining soil mix and kept moist until they establish new roots.
Propagation of Crotalaria tsavoana Polhill is relatively easy as it can be propagated through seeds, cuttings or division. By utilizing the propagation methods described above, this plant can be propagated and cultivated with ease.
