Propagation through stem cuttings:
You can also propagate Rinorea kemoensis A.Chev. through stem cuttings. Follow these steps:
- Take a healthy stem cutting from the parent plant. The cutting should be 10-15 cm long and have at least two sets of leaves.
- Remove the lower leaves and cut the stem at a 45-degree angle.
- Dip the cut end of the stem in rooting hormone powder.
- Prepare a pot with well-draining soil and make a hole in the center.
- Place the stem cutting in the hole so that at least one set of leaves is above the soil level.
- Water the soil and cover the pot with a plastic bag to create a humid environment.
- Place the pot in a shaded area with indirect sunlight.
- Remove the plastic bag when you see new growth, which usually takes 4-6 weeks.
- Once the plant grows to a considerable size, you can transplant it to the garden.
