Propagation of Hibiscus bequaertii De Wild.
Hibiscus bequaertii De Wild. can be propagated through seeds, cuttings, and layering.
Seed Propagation
Seeds should be collected from the dried capsules of the plant. Sow the seeds in a well-draining mix of sand, soil, and organic matter in equal parts. Cover the seeds with a thin layer of soil and keep them moist. Germination can take up to a month. Once the seedlings are about 3 inches tall, they can be transplanted into individual pots or to the final planting spot.
Cuttings
Cuttings can be taken from the stem tips of the plant during the growing season. The cuttings should be about 6 inches long and should have at least two leaf nodes. Remove the lower leaves and dip the cut end in a rooting hormone. Plant the cutting in a well-draining mix of sand and perlite in equal parts. Water the cutting and keep it in a shaded area with high humidity. Roots should develop within 4-6 weeks. Once the roots have developed, the cutting can be transplanted to a larger pot or to the final planting spot.
Layering
Layering can be done in the early spring or late fall. Choose a low branch of the plant and bend it down to the ground. Dig a small trench and bury a section of the branch under the soil. Put a stone on the buried branch to keep it in place. Water the area regularly. After a few months, roots should have developed from the buried section. Cut the branch from the mother plant and transplant it to a new pot or to the final planting spot.
