Seed Propagation
The easiest and most common method of propagation for Oligomeris dipetala var. spathulata is through seed. The plant produces seed pods that contain numerous seeds, and these can be collected once the pods have turned brown and dry. The seeds can be sown in pots or directly in the garden bed during spring or fall. It is essential to ensure that the soil is well-draining and that the seeds are covered with no more than 1-2mm of soil. Moistening the soil regularly will help with germination. Seedlings may take up to three weeks to emerge, and they can be transplanted to their permanent location once they have grown four to six true leaves.
Division Propagation
The next most common method of propagating Oligomeris dipetala var. spathulata is division. The division is best done in spring when the plant is actively growing. Carefully dig up the clump and gently tease the roots apart. Each division should have at least a few roots and shoots. Replant the divisions at the same depth as they were in the original clump, and water them well. Avoid disturbing the plant for several weeks to give it time to adjust to its new location.
Cuttings Propagation
Oligomeris dipetala var. spathulata can also be propagated from cuttings. Take stem cuttings that are 5-10cm long from the parent plant during the growing season. Ensure the cutting has at least two leaves and no flowers. Dip the cut end of the stem in rooting hormone, and plant in well-draining soil, ensuring the soil stays moist. Grow the cutting in a warm and bright location, and it should root in about 4-6 weeks. Afterward, it can be transplanted to its permanent location.
With these methods, one can propagate Oligomeris dipetala var. spathulata easily and successfully, ensuring an abundant and beautiful display of this plant in gardens and landscapes.
