Propagation of Drypetes gerrardii Hutch. var. grandifolia Radcl.-Sm.
Drypetes gerrardii Hutch. var. grandifolia Radcl.-Sm. can be propagated by seeds, cuttings, and air layering.
Propagation by Seeds
The seeds of Drypetes gerrardii Hutch. var. grandifolia Radcl.-Sm. can be obtained from mature fruits. The fruits should be harvested when they are fully ripe. The outer layer of the fruit should be removed, and the seeds should be washed under running water to remove any remaining pulp. The seeds can then be sown in a well-draining seedling mix and covered with a thin layer of the same mix. The seedling container should be kept moist, but not waterlogged. The seeds will germinate in 3 to 6 weeks.
Propagation by Cuttings
Cuttings can be taken from the semi-hardwood of Drypetes gerrardii Hutch. var. grandifolia Radcl.-Sm. during late spring to summer. The cutting should be about 8 to 10 cm long with at least two leaves. The lower leaves should be removed, and the cutting should be dipped into rooting hormone powder. The cutting should be planted in a container filled with well-draining soil mix and watered. The container should be covered with a plastic bag, and the cutting should be kept in indirect sunlight. The cutting will root in 3 to 4 weeks.
Propagation by Air Layering
Air layering can be done during late spring to summer. A stem of Drypetes gerrardii Hutch. var. grandifolia Radcl.-Sm. should be selected, and a ring of bark should be removed from the stem. The cut area should be dusted with rooting hormone powder, and it should be wrapped with moist sphagnum moss. The moss should be wrapped with a plastic bag and tied at the top and bottom. The moss should be kept moist and checked periodically for root growth. When the roots have developed, the new plant should be separated from the mother plant and planted in the desired container.
