This plant also has a special need to pay attention to, and other plants are different, they like to live in a weak alkaline environment, the best is sandy soil.
This kind of herbal medicine needs a large amount of water, so it's best to choose a place close to the water source, preferably a low-lying one. Loose and fertile soil is more suitable for it. If possible, it is better to choose sandy soil with good drainage. Before sowing, it is necessary to treat the soil to a certain extent. It is better to plough deeply for 20 to 30 cm, and add proper amount of fertilizer inside, but do not use chemical fertilizer, otherwise it will destroy their original ecological feeling. All sides should make good drainage measures, so that the amount of water is too large.

Weeding must be done in time. When you see the grass, you can pull it out. When the seedlings grow to 67 cm, you can loosen the soil. At this time, loosening the soil will not hurt the seedlings, and the seedlings will not be pulled off the ground because they are too small. When the parts on the ground are closed to each other, there is no need to loosen the soil. When the roots leak out, we should cultivate the soil in time.
