5. Separate planting: Acorus calamus should clean up the dead branches and leaves before overwintering, burn or rett fertilizer centrally, renew open field cultivation for 2 ~ 3 years, force ramet when planting is too crowded for a long time, replant after changing soil, and change pot planting once every 2 years.
