1. Seeds: select suitable seeds, and then soak them in cold water for about 24 hours six hours before sowing, and then wash them slowly and replace with fresh water. Then scoop it out and wrap it with gauze, put it in the environment of 15 ℃ to speed up sprouting, wait until the seeds start to show white, then you can sow.
2. Seedling raising: the sand bed to be planted must be loose and have good drainage effect. Its seed is very small, often some seeds stick together, it is difficult to separate, sowing is very difficult to be even, so you can mix some fine sand, mix it and then sow it, cover it with a thin layer of soil, the thickness cannot exceed 1cm.
3. Close planting: in the first ten days of September, it's a good time to plant. It can be planted reasonably to ensure a good temperature, preferably around 15-20 ℃.
Its adaptability is very strong, there are not too many restrictions on the time of seedling. It can be planted all year round in the south, but try to avoid summer. The best choice in the north is in spring and autumn, sowing is very suitable, July is the most appropriate, at this time the temperature is higher, conducive to germination, plus the air humidity content is higher
