Then take it out, wrap it with gauze, put it in the environment of 15 ℃ to promote germination, and sow it when the seeds begin to show white

2. Seedling raising: the sand bed planted must be loose and have good drainage effect. Its seeds are very small. Some seeds are often bonded together, which is difficult to separate, and it is difficult to sow evenly. Therefore, it can be mixed with some fine sand, mixed and then sown. It is covered with a thin layer of soil, and the thickness cannot exceed 1cm

3. Close planting: early September is a good time for planting. Close planting can be carried out reasonably to ensure a good temperature, preferably around 15-20 ℃

2、 Seedling raising time

In the north, it is best to choose spring and autumn. Sowing is very suitable, and July is the most suitable. At this time, the temperature is high, which is conducive to germination. In addition, the humidity content in the air is high
