Seed preparation: before planting sweet beans, you should first choose good seeds, and use full seeds that are not eaten by insects. In order to ensure better germination, the seeds bitten by insects should be selected before planting. If the quality of seeds is poor, the germination rate will be obviously reduced, so it is very important to choose seeds with better quality.

Soil preparation: before planting, dig deep into the land and apply some decomposed organic fertilizer. The location of land selection is also better, and it is best to choose a place with good transparency, so that the color of sweet beans will be brighter, otherwise the growth period will not see the sun for a long time, and the yield will also be affected.

Sowing: At the beginning of planting, generally put 2-3 seeds in each hole, and the distance between each hole should not be too close, about 13- 15cm. If the planted land is particularly dry, it needs to be watered and planted as needed. After the seeds are buried, cover them with 2-3 cm of soil.
