Propagation of gnidia can be achieved through seed sowing, cuttings, or division. Key factors for success include ensuring adequate light exposure, maintaining appropriate temperature, and using well-draining soil. Specific considerations may involve treating seeds prior to sowing or providing a rooting hormone for cuttings. Propagation can present a moderate difficulty level due to these species-specific requirements. To propagate by cuttings: 1) Take healthy cuttings during the growing season, 2) Dip the base in rooting hormone, 3) Plant in a well-draining soil mix, 4) Keep the soil consistently moist, 5) Place in a warm spot with indirect light, and 6) Wait for roots to establish before transplanting.
