The primary propagation method for kumara is vegetative, typically through tubers or cuttings, as it rarely produces seeds. Key factors include warm temperatures, well-draining soil, and sufficient sunlight. Special technique considerations might involve curing cuttings before planting to reduce rot. Propagation is generally considered easy, although careful handling of tubers to prevent damage is crucial. The steps are as follows: 1) Choose healthy tubers or cuttings, 2) Allow cut surfaces to callous over, 3) Plant in well-draining soil, 4) Keep soil consistently moist and warm, 5) Provide ample sunlight, 6) Wait for sprouts to develop, then 7) Transplant established seedlings.
