Propagation of isodon typically involves seed sowing, stem cuttings, or division. Key factors for success include providing well-draining soil, maintaining consistent moisture without waterlogging, and ensuring adequate light and warmth. Special considerations for isodon may require stratification of seeds to improve germination rates. The difficulty level is generally moderate, though some steps like seed stratification could challenge beginners. To propagate by cuttings: (1) Snip a healthy stem segment, (2) Dip the cut end into rooting hormone, (3) Plant into a soil mix, (4) Keep the soil moist and in warm, indirect light, and (5) Wait for root development before transplanting.
