Cangzhu Planting Method: Key Points for Root Division Propagation and Field Management

Cangzhu (sometimes written as Cangzhu, generally referring to the Chinese medicinal herb Atractylodes lancea) is a relatively uncommon companion plant whose rhizome can be used as medicine and has very high medicinal value. It generally grows in hilly areas surrounded by gullies, at higher altitudes, and in places with fresh air, preferring a cool and partially shaded environment. To grow Cangzhu well, first understand its "temperament," then focus on the two key links of propagation and field management.

Spring Root Division, Propagation and Planting

Cangzhu is mostly propagated by root division, preferably in April in spring. The specific method is: dig out the old plants with their roots, shake off the soil, and use a knife to cut the roots into several small sections, each of which must carry 1 to 3 root buds - this is the key to ensuring survival. Plant the cut root sections into prepared plots according to the propagation and planting method, with the buds facing upward and the soil pressed firm after planting. Keep the soil moist after planting to encourage rooting and sprouting.

Weed Frequently During the Seedling Stage, and Do Not Relax Management After Planting

Cangzhu grows slowly during the seedling stage and is most afraid of weeds competing for light and nutrients, so weeding must be done frequently. After planting and survival, management also cannot be relaxed. Intertillage, weeding, and hilling should be carried out in time, which both loosens the soil and increases aeration, and also prevents lodging. As for topdressing, apply dilute manure 1 to 2 times in combination with intertillage. Only when fertilizer and water keep up will the rhizome grow plump and yields be guaranteed.

High Medicinal Value, Worth Growing with Care

Cangzhu has a long history of medicinal use. It can treat dampness excess troubling the spleen, fatigue and somnolence, vomiting and diarrhea, and abdominal distension and pain. It has a certain therapeutic effect on gastrointestinal diseases such as poor appetite and dysentery, and also has certain efficacy for seasonal colds, foot weakness, wind-cold-damp bi syndrome, and night blindness. With wide uses and stable demand, if you grow quality, you naturally will not worry about sales.

Finally, a reminder: climate and soil conditions vary from place to place, so planting time and water and fertilizer measures should be adapted to local conditions. After harvest, the rhizomes should be placed in a ventilated and dry place to dry and store. As long as you firmly grasp the two passes of root division propagation and daily management, growing Cangzhu well is not difficult.
