The invention discloses a polygonum multiflorum planting method which includes that soil is preferably deep, fertile, loose and good in water discharge and is better faintly acid and neutral sandy soil, the required PH value range is 6-7.5, and a plough layer is larger than 30cm. Soil preparation, base fertilizer application, furrow preparation and transplanting are conducted. Planting is conducted in sunny days after raining or in cloudy days in March or April each year, fixed planting is conducted on the furrow surface with the distance between plants in rows and between the rows being 20-30cm, and 9000 seedlings are planted each acre. After planting is finished, watering is conducted to fix the roots if it is dry or the soil is dry. Healthy cutting seedlings free of pest diseases and multiple in white roots are selected as planted seedlings. Intertillage weeding, top application and pruning are conducted. After the transplanted seedlings survive, harvesting is conducted when the tender stem is 20-50cm in length, the length of polygonum multiflorum vegetable is preferably 10-20cm, the length of polygonum multiflorum tea is preferably 2-3cm, and harvesting is conducted 2-3 times every month. The roots of the polygonum multiflorum can be harvested in autumn or winter of the third year or in spring of the second year after the seedlings are planted. By means of the method, the yield can be improved, and quality is stable.
