Propagation of Cassia kirkii Oliv. var. guineensis Steyaert
Cassia kirkii Oliv. var. guineensis Steyaert is a perennial plant that belongs to the Fabaceae family. It is native to West Africa, specifically Guinea, Ivory Coast and Liberia. The plant can grow up to 6m tall and produces yellow flowers. Propagation of the plant can be done through the following methods:
Seed Propagation
Seeds are the common methods of propagating the plant. The seeds should be collected when the pods start to dry out. Ensure the seeds are dry and intact and then sow them in seed trays or pots with well-draining soil. Place the trays or pots in a warm and bright location with moderate moisture. Germination generally takes place from 7 to 14 days. Once the seedlings have grown to a substantial size, they should be transferred to larger pots or containers and later transplanted into the garden when they are strong enough.
Cuttings Propagation
Cassia kirkii Oliv. var. guineensis Steyaert can be propagated through cuttings. Cuttings should be collected from mature plants with woody stems. The cuttings should be about 10 to 15 cm long and ensure that there are at least two leaves on the cutting. Remove the lower leaves and plant the cutting in pots or trays with well-draining soil. Cover the pot or tray with a plastic sheet to increase humidity and place it in a warm bright area. Once the cutting has started to develop roots and new growth, it can be transplanted to a larger pot or garden.
Air Layering Propagation
Propagation through air layering involves making a small cut in a branch of the plant and then encouraging roots to develop in that area. This method is commonly used for plants with a woody stem. Choose a branch without flowers and use a sharp knife to make a small 2-3cm cut around the stem. Apply rooting hormone into the cut and pack the area with moist sphagnum moss. Cover the moss with plastic or cling wrap and tie the wrap above and below the moss with string. Ensure that the moss stays moist and remove it after 4 to 6 weeks when roots have developed. Plant the new plant in a pot or larger garden bed.
