How to Grow Polygonum multiflorum (He Shou Wu) Well? Latest Cultivation Techniques Explained
Polygonum multiflorum (He Shou Wu) is a medicinal herb with high medicinal value and nutrition. Currently, cultivating Polygonum multiflorum is also one of the choices of many rural friends, so how should it be grown to achieve a relatively high yield? Qinnong Network will explain here how to achieve high quality and high yield.
1. Seed breeding
When preparing Polygonum multiflorum seeds, many rural friends choose to sun-dry them and then store them in order to dry them quickly. In fact, the best method is to sun-dry them until about half-dry and then air-dry them, as the seed survival rate will be much higher this way. Second, the storage bag is best made of breathable and water-absorbent cloth, which helps preserve seed vitality. Only then can they grow quickly and well when sown.

Polygonum multiflorum heavily consumes soil fertility, so before sowing, the soil must be well nourished, and sandy soil is best. First, at the end of December, carry out the first soil preparation, evenly spread farmyard manure, and then let it absorb the fertility over time. Around early February, apply additional fertilizer, that is, the second application of farmyard manure. After this application is finished, begin turning the soil in early March to prepare for sowing. After two rounds of fertility supplementation, the soil fertility will be extremely sufficient.
3. Fertilization
Sow within 2-3 days after turning the soil, at a sowing depth of about 2 cm. In the few days before sowing, more water needs to be supplied; water once a day before germination, once every 3 days after germination, and stop after one month. At about 2 months, it is about to enter the rapid growth period of the root tubers, and at this time some compound fertilizer needs to be applied to avoid insufficient nutrition, basically once every half month. Stop 1 month before harvest. When fertilizing, everyone must pay attention: Polygonum multiflorum that shows yellowing indicates too much fertility.
4. Management
Field management is a very important matter. When there is too much water, drainage should be carried out. If Polygonum multiflorum grows too densely in some places, it should be transplanted in time to avoid poor nutrition in that area. Of course, weeding is also an unavoidable task. If your planting area is too dense, the editor recommends that you use stakes to free up more space so that each Polygonum multiflorum plant can enjoy a sufficient sunbath.
Polygonum multiflorum still has great economic prospects, and everyone must be careful when planting it. More planting insights are all on Qinnong Network. You can follow us more, as selected planting techniques are updated every day!
