Before sprouting in spring, dig out the rhizomes and divide them into several plants based on the size of the old rhizomes. Plant them with a spacing of about 30cm x 30cm between rows.2. Propagation by seeds: In April to May, create shallow furrows about 30cm apart on the seedbed, evenly scatter the seeds into the furrows, cover with soil about 0.5cm deep, keep the soil moist, and after germination, pay attention to weeding, loosening the soil, and thinning out seedlings in overcrowded areas.
