Propagation of Cassia falcinella Oliv. var. longifolia Ghesq.
Cassia falcinella Oliv. var. longifolia Ghesq. is a species of plant that belongs to the Fabaceae family. It is commonly known as the sword-leaved cassia. The plant is native to East Africa and is becoming increasingly popular in other parts of the world because of its ornamental value. Propagation of this plant can be achieved through various methods, including:
Seed Propagation
The sword-leaved cassia can be propagated from seeds. The best time to plant the seeds is during the rainy season. Before planting, soak the seeds in water for a few hours to soften the seed coat and improve germination. Sow the seeds in well-drained soil and cover them lightly with soil. Keep the soil moist but not waterlogged. The seeds should germinate within two to three weeks.
Cuttings Propagation
Propagation of sword-leaved cassia can also be achieved through stem cuttings. Cuttings should be taken from the plant during the growing season, preferably from the softwood. The cuttings should be about six inches long and should have at least two nodes. Remove the leaves from the bottom node and dip the cut end in rooting hormone before planting the cutting in well-drained soil. Keep the soil moist and place the cutting in a bright but shaded area. Roots should develop within two to three weeks.
Division Propagation
Division of the sword-leaved cassia is another method of propagation. This method is ideal for mature plants that have formed clumps. Dig up the plant and gently separate the clumps, ensuring that each piece has a good root system. Repot the clumps in well-drained soil and water well. The plant should be kept in a shaded area until it has recovered from the transplant shock.
