Propagation of Ochna sapinii De Wild.
Ochna sapinii De Wild. can be propagated through seeds, cuttings, and air layering.
Propagation through Seeds
Seeds of Ochna sapinii De Wild. can be collected and sown directly in the soil or in seed trays containing a well-draining soil mix. The seeds should be covered with a thin layer of soil and kept moist. Germination can take up to 1-2 months, and the seedlings can be transplanted to their permanent location after they become established.
Propagation through Cuttings
Ochna sapinii De Wild. can be propagated through softwood or semi-hardwood cuttings. Softwood cuttings can be taken in the spring, while semi-hardwood cuttings can be taken in the summer. Cuttings should be taken from healthy and disease-free plants and should be 5-10 cm long. The cuttings should be dipped in a rooting hormone and then inserted into a well-draining soil mix. The soil should be kept moist, and the cuttings should be placed in a shaded area until roots develop.
Propagation through Air Layering
Air layering is a propagation method in which a section of a stem is stimulated to produce roots while still attached to the parent plant. For Ochna sapinii De Wild., the stem to be air layered should be selected in the spring and should be 1-2 cm in diameter. A section of bark should be removed from the stem, and rooting hormone should be applied to the exposed area. The area should then be wrapped in damp sphagnum moss and covered in plastic. After a few weeks, roots should begin to form. Once a strong root system has developed, the air layer can be removed from the parent plant and potted in a well-draining soil mix.
