1. Cut the germinated potato into pieces. If the potatoes stored at home germinate, they can be cut into small pieces, and each piece should have buds. In addition, some plant ash is smeared on the cut surface of the potato block, which has a certain bactericidal effect, prevents the incision from rotting and reduces the survival rate of new species.

2. To prepare the soil, potatoes have high requirements for the soil. The soil with deep topsoil, loose soil, good drainage and air permeability and rich organic matter is most suitable for planting potatoes. Humus soil can be mixed with a small amount of river sand, which can strengthen the gap of soil and is beneficial to root respiration, so appropriate base fertilizer should be applied.

3. The next step is planting, that is, the sprouted part of the potato should be placed in the soil upward, and then covered with fine soil with a thickness of 1-2 cm. After planting, spray a proper amount of water with a watering can. It is found that after the soil is dried, it is beneficial to the growth and development of potatoes to replenish water in time and keep the soil moist.

At the same time, do a good job of shading, don't let it accept direct light, and give it a suitable temperature environment. The optimum temperature is about 20℃. If it is higher than 25℃, the tuber may stop growing. The whole growth period of potato is about 90 days. During this period, the light, temperature and humidity should be controlled.
