Primary propagation for bontia includes stem cuttings and seeds. Key factors for propagation success are bright indirect light, consistent warmth, and well-draining soil. Special considerations involve maintaining high humidity for cuttings and preventing seedlings' soil from becoming waterlogged. Propagation can be moderately challenging due to these requirements. To propagate, take a 4-6 inch cutting, remove lower leaves, dip in rooting hormone, plant in a moist potting mix, cover to retain humidity, and place in warm, indirect light. For seeds, sow in a light seed-starting mix, lightly cover, keep moist, and provide warmth and light until germination.
