Seeds from the Ochna mechowiana O.Hoffm. can be used for propagation. The seeds from the plant are small and black and need to be collected from the mature fruits that have turned red. Once you collect the seeds, they must be sown in seedbeds filled with well-drained soil. Cover the seeds with a layer of soil and water lightly. The seedbeds should then be placed in a shaded area and should be watered regularly. Germination usually occurs within 2-4 weeks.
Propagation from Cuttings
Propagation from cuttings is the more preferred method of propogation for Ochna mechowiana O.Hoffm. You need to collect hardwood cuttings from healthy and mature plants during the dormancy phase. The cuttings should be around 15-20cm in length and should have at least two buds. Remove all the leaves except for two at the top and insert the cutting into a well-draining soil mixture. Water the soil until it's moist and cover with a plastic bag to retain moisture. The cuttings should root in around six weeks time.
Propagation from Layering
Propagation from layering is another method used for propagating Ochna mechowiana O.Hoffm. You can select a low-growing branch on the parent plant and peel off a small strip of bark from the underside of the stem without breaking off the branch. Apply rooting hormone powder to the wounded part of the stem and then twist the stem to create a small wound. Peg the section into a separate container with well-draining soil and water it lightly. Once the roots have developed, the new plant can be separated from the parent plant and potted individually.
