1, when planting yam, ensure the temperature. It can grow on the ground above 10 degrees Celsius, so it is not appropriate to choose the time to ensure the temperature, either too high or too low.

2. The planting time is determined according to the local climate. If you choose warm places such as the south, there is no severe cold weather in these places, so the planting time is not fixed, and there are not too many restrictions.1-May can be used. For example, the Yangtze River basin can be selected in March, and the Huaihe River region can be slightly postponed from late March to early April. However, planting in northern areas is usually in March-April in spring, and in northern China, it is ok to choose in March. In northeast China, because of the cold, the time can be postponed and chosen around April.

3. Precautions: If you choose to plant in a greenhouse, there is not so much time limit. The surface temperature here is relatively high, so you can plant it around New Year's Day, and the harvesting time will be much earlier, just in time to stagger the centralized listing, which is more advantageous in price. The specific planting time can be selected according to your personal situation.
