Suitable time for sowing Chinese milk vetch

Astragalus membranaceus is a biennial plant of the Leguminosae family. It mainly reproduces and spreads through seeds. It will bloom about two months after sowing. The flowering period is from February to June of the same year, which varies according to the planting time.

Chinese alfalfa is suitable for sowing in mid-March and mid-September in autumn every year. Among them, sowing in spring is the best time. At this time, after the seeds germinate, as the seedlings grow, the temperature and precipitation will gradually increase, and the growth rate will become faster and faster. It will mature after a few months.

Milk vetch sowing method

1. Land preparation and soil cultivation

Before planting sweet clover, the soil must be loosened first to prevent soil compaction that affects the growth of seedlings. Then a certain amount of peat soil can be mixed into the soil to improve air permeability.

2. Plant and water

Next, plant the sweet clover seeds in the treated soil, and then use a small amount of water to irrigate it to keep the soil in a relatively moist environment, making it easier for the seeds to germinate.

Key points and techniques for planting Chinese milk vetch

1. Lighting

After the sweet vetch seedlings emerge from the soil, this is the time when the plants are most vulnerable. If the light intensity is too high, shading should be carried out in time to avoid plant burns.

2. Moisture

During the cultivation process of astragalus, once the seeds germinate, they will use their roots to obtain nutrients. At this time, the amount of soil water must be strictly controlled. Excessive watering can easily cause the roots and stems of the plant to be unable to breathe normally.
