The seeds are mixed with the plant ash and evenly distributed in the ditch. The depth of covering soil is about 0.5cm. Finally, the grass is covered to keep the seedbed moist. After sprouting, the grass cover can be removed, and the seedlings can be raised for 1-2 years. After the seedlings are about 1 meter high, they can be planted.

Each hole is planted with a seedling. The soil is covered tightly, the root water is poured, and the bottom fertilizer is applied.
When transplanting, one plant can be divided into 2-3 plants for transplanting. The reasonable distance should be controlled. Generally, the plant spacing is 1 meter, and the row spacing is 2 meters.
