In Sichuan region, the whole plant is dug up in September to October, the underground stems are cut off, and then divided into individual plants to be used as seedlings. After preparing the soil, a raised bed 1.3m wide is built, well-rotted compost is applied and mixed with the soil. Holes are dug at a spacing of about 16cm between rows and plants, about 10cm deep. The seedlings are planted as the holes are dug, with the soil covering just over the growing point, pressed firmly, and then covered again until level with the bed surface. The plants are small, so we need to pay attention to weeding. Weeding is usually done by hand to avoid damaging the underground rhizomes and affecting growth. About 10 days after planting, pig manure water can be applied for overwintering. In the second year, when new leaves sprout in spring and grow vigorously in summer, pig manure water is applied again, and well-rotted compost is spread in winter. For disease and pest control: pests such as slugs and snails can be controlled by sprinkling fresh lime powder in the morning.
