Primary propagation for diosma is through cuttings or seeds, with cuttings being the most common due to the plant's slow seed germination process. For successful propagation, ensure use of a well-draining soil mix and maintain moderate temperatures, as diosma is sensitive to extreme conditions. Semi-hardwood cuttings should be taken in late summer. Rooting hormone can enhance success rates, which are generally moderate with proper care. Monitor light, providing bright, indirect light to encourage growth. Steps include selecting healthy mother plants, preparing cuttings of 4-6 inches, dipping in hormone, planting in soil, watering, and waiting for root development before transplanting.
