What are the latest propagation methods for kudzu?

Kudzu can be eaten raw, made into kudzu powder, and also used as medicine. It is a crop with extremely high economic value and is grown in most parts of our country. Besides sowing, there are several other propagation methods. Let's take a look together below.

1. Propagation by sowing

Every year in September-October, when the pods mature, harvest the pods, dry them in the sun and thresh them, remove impurities, and keep the seeds in storage for later use. In the following spring, when the temperature rises, choose a suitable time to prepare for sowing. First select a sandy loam site with deep soil and good drainage, apply base fertilizer while preparing the land, and then sow. Sowing can be done in holes or in rows. Pay attention to sowing density when sowing, and thin the seedlings in time after they emerge. Combine with cultivation and weeding, and when the seedlings have grown to a certain extent, transplant them at the right time.

2. Propagation by cuttings

For propagation by cuttings, select thick and strong kudzu vines that have grown for 1-2 years on the mother plant, cut each 2-3 stem nodes into a section, and insert them into loose, moist soil or fine sand. Using their regenerative ability, they will root in about one month, and soon form new plants. Because cuttings are in short supply, this method is not suitable for propagating seedlings on a large scale, and its disease resistance is relatively weak, making it very easy to accumulate a large number of viruses, causing the kudzu variety to degenerate and reducing yield and quality.

3. Propagation by root heads

Root head propagation, as the name suggests, uses the underground rhizomes of kudzu for propagation. When harvesting by digging in winter, cut off about 10 cm of the robust root head and plant it directly into the production site. After the following spring, new seedlings can grow, and when the seedlings have grown to a certain extent, transplant them to the planting site in time.

4. Propagation by layering

Layering propagation is somewhat similar to cutting propagation and is generally carried out in summer. When the plants grow luxuriantly in summer, select thick, strong, disease-free kudzu vines, and at every 1-2 nodes, loosen the soil under the nodes, pile soil over the nodes, and press the nodes into the soil. The stem nodes buried in the soil can be cut with a knife in several places. Water during drought to help them root as much as possible. After rooting, apply thin fertilizer water in time and remove weeds. After the following spring when shoots sprout, cut them off to become individual plants, then lift the seedlings and transplant them.
