For Angelica sinensis sown directly in winter, combine with topdressing before winter, cover the seedlings with manure or add about 1 cm of fine soil over the seedlings to protect them from frost damage; for Angelica sinensis raised in seedbeds and then transplanted, storage of seedlings should be done well in winter; for Angelica sinensis grown for seed, in order to improve seed yield and quality, before harvest it is necessary to select robust and uniform plants growing on high mountains or mid-slope land for seed production. After that, cut off the aboveground part of the seed plants, remove all weeds, let them overwinter naturally, and keep watch frequently to prevent livestock from entering and trampling them, which would cause missing plants. In the following spring, if weeds are seen growing, they can be pulled out by hand; at this time the root system is spread throughout the soil surface, so hoeing for weed control and fertilization should not be used, to avoid cutting the root system and hindering plant growth.
