The cuttings should be dipped in a rooting hormone and planted in well-draining soil. The soil should be kept moist, and the cuttings should be placed in a shaded area to prevent wilting.
The cuttings typically take around 3-4 weeks to develop roots and can then be transplanted into larger containers or directly into the garden.
Whether propagated by seeds or cuttings, Bonamia lebrunii Petit ex Evrard requires specific growing conditions to thrive. These conditions include well-draining, nutrient-rich soil with a pH of between 5.5 and 6.5, and a consistent source of moisture. The plant also requires bright, indirect sunlight and protection from strong winds.
