Ensure to cut the stems just below the node, which should be sterilized with a fungicide to prevent fungal infection. The cuttings should be dipped in rooting hormone and planted in a sterile rooting medium, such as sand or peat moss. The rooting medium should be kept moist, but not waterlogged.
Propagation through division: Another method of propagation is by division. Clumps of well-established plants can be divided into smaller sections with a sharp knife. Each section should have at least one viable shoot and root system. Plant each section in a well-draining soil mixture, water it regularly, and place it in a location with bright, indirect light.
Propagation through seeds: Although not commonly used, Swertia petitiana A.Rich can also be propagated through seeds. Seeds should be collected from mature plants, and the outer seed coat should be removed by soaking in warm water for one hour before planting. The seeds can be sown in a sterile potting mix in a well-draining container, and the soil kept moist but not waterlogged. The seedlings should be transplanted to individual containers once they are about 5 cm tall.
