When is the best time to grow sweet potatoes?

Sweet potatoes are best planted in April and May.

At this time, the temperature is stable and the rain is abundant, which is very suitable for planting sweet potatoes and can promote their healthy growth. After planting, the sweet potato should be watered once in time, and the seedlings should be checked and replenished in time until new roots and tubers grow, ensuring the whole seedling, intertillating once every 10- 15 days, and spraying some new high-fat films.

Method for planting sweet potato

1, seed selection: The sowing method of sweet potato is very simple. First, choose seeds to ensure that the seeds are strong and disease-free, and choose ones with large volume and many buds, so that the germination grows quickly. In addition, the seeds should be soaked in carbendazim solution for disinfection before planting, which is about 10 minute.

2. Soil: Sweet potato is suitable for growing in deep soil with good drainage. You can choose fields with open terrain, sunny ventilation and convenient irrigation and drainage as planting sites, dig deep into the fields to dry, and then spray organic liquid fertilizer on the fields to improve soil fertility.

3. Sowing: it can be planted after soaking and disinfection, directly placed in the dug ditch, and then covered with soil in time. Pay attention to heat preservation treatment in the later stage. If the temperature can't reach, cover it with plastic film and uncover it when the seedlings grow to 30-40 cm. In the later stage of cutting propagation, the roots of seedlings should be covered with soil.

3. Watering: The water consumption in the early stage of sweet potato planting is large, so it needs to be watered frequently. Usually water it once a day. Over time, as long as the amount of watering is reduced in the later period, watering once a week will meet the demand.
