1、 Preparation of matrix

For sowing and reproduction, the selection of substrate is also very important. The texture is as fine as possible. It not only has drainage, but also has water retention, which can promote seed germination. The flowerpot can be made of earthenware or pottery. The material should be breathable, which can ensure the permeability and drainage. It doesn't need to be too high. The bottom of the flowerpot is padded with large-grained volcanic rock as the bottom, which can increase the drainage. The substrate mixed with nutrient soil and coarse sand can ensure good nutrition and air permeability

2、 Select seed

The seeds should be plump and full as much as possible without shrinkage, diseases and insect pests, otherwise it will affect the subsequent growth and can be purchased directly from the seed store

3、 Sowing

The best choice is in spring, when the climatic conditions are also suitable. Fill the selected soil into the flower pot and sow seeds on the surface. The seeds are covered with a thin layer of soil, which does not need to be too thick, otherwise it will affect germination and growth. The flower pot is covered with a layer of fresh-keeping film, which can increase the temperature and ensure the humidity, and promote the germination of seeds as soon as possible

4、 Subsequent maintenance

After sowing, add appropriate water. Dip the pot and put it in the bright sun
