Bridelia grandis Pierre ex Hutch. subsp. puberula J.Léonard can be propagated through seeds or cuttings.
Propagation through Seeds
Seeds should be collected from mature fruit capsules that have turned brown. The seeds should be cleaned and stored in a dry and cool place until planting. Before planting, the seeds should be soaked in warm water for about 24 hours. This helps to enhance germination rates. The seeds can then be planted in well-draining soil in seedling trays. They should be covered with a thin layer of soil and watered gently. The trays should be kept in a warm and shaded area until the seeds germinate. Once the seedlings have developed true leaves, they can be transplanted into individual containers.
Propagation through Cuttings
Softwood cuttings can be taken from Bridelia grandis Pierre ex Hutch. subsp. puberula J.Léonard during the growing season. Cuttings should be about 10-15 cm long and should have at least 2-3 nodes. The leaves on the lower half of each cutting should be removed, while the leaves on the upper half should be trimmed to reduce water loss. The cuttings should be dipped in rooting hormone and planted in well-draining soil. They should then be covered with a plastic bag to increase humidity and placed in a partially shaded area. After rooting, the cuttings can be transplanted into individual containers.
