1. Planting time: Generally, white sweet potatoes are planted in April and May. Early-ripening white sweet potatoes can usually be dug out and eaten in May or June, and medium-ripening ones can usually be planted in August or September. , which is the most common variety that appears in autumn. Of course, there is also the latest variety that can only be eaten in October or November. Therefore, the planting time is always April or May, but the maturity time is also different due to different regions.

2. Planting method: Land selection and soil preparation: White sweet potatoes are suitable for planting in land with loose soil, good ventilation and drainage functions. Planting in land with heavy clay that is not conducive to drainage will cause white sweet potatoes to mature during their maturity. The white sweet potatoes you see are probably only as big as your little finger. Directly sow 3 or 4 seeds at certain intervals (25-50 cm) in the dug soil, cover with film or spread a layer of moss to cover the seeds. The second method is to directly press the seeds. Sow seeds in rows in a crawling manner. Do not scatter too many seeds in each row, and cover the seeds in the same way.

Field management: After the white sweet potato germinates, if thinning is found, it is necessary to replenish the seedlings in time. Fertilize for the second time when the seedlings grow to 5-10 cm. If there are weeds in the field, weeding should be done while fertilizing. , because the white sweet potato vines grow in different directions, so we need to guide them to grow in one direction so that they can find the source when harvesting. Moreover, the white sweet potato vine must be topped and flowered in time to prevent it from growing too long and consuming nutrients, so that the white sweet potatoes will be large and fresh.
