Cut down the whole grass, then expose it to the sun, and take out the seeds in the plant, which can be saved for sowing in the next spring

2、 Select soil

The requirements for soil are not strict and there are not many restrictions. If you plant it on the ground, you can choose a sunny place, which can be met in a normal countryside. If the potted loam is well prepared, it can ensure sufficient permeability and drainage

3、 Sowing
