Sweet potato is suitable for growing in fertile sandy loam. When planting sweet potatoes, we should first apply decomposed organic fertilizer and cake fertilizer to the soil, then bury the sweet potatoes in the soil and cover them with plastic film. After about half a month, the sweet potato will sprout. At this time, the plastic film should be uncovered.

Sweet potato is a fertilizer-loving plant, and it needs sufficient nutrients during its growth. When cultivating sweet potatoes, it is necessary to apply dilute manure water once after the plants emerge to speed up their growth, while in the season when sweet potatoes grow vigorously, it is necessary to apply phosphate fertilizer and potash fertilizer two or three times to improve their yield.

Matters needing attention in sweet potato planting

1. Before planting, sweet potatoes must be planned and arranged according to their growth habits. Sweet potato planting should be carried out in the season when the temperature is relatively stable, usually in spring and summer. At the same time, pay attention to the depth and distance of sweet potato. Generally speaking, the spacing between sweet potato plants should be kept at a certain distance, so that the growth of sweet potato can be unimpeded. In addition, pest control should be carried out to avoid the harm of pests and diseases to sweet potatoes.

2. It is very important to choose the soil suitable for sweet potato growth. Sweet potatoes need plenty of sunshine and well-drained land, and the soil should be easily ventilated and rich in organic matter. In order to ensure the fertility of the land, fertilization should be done once a year. These methods can improve the fertility and water storage capacity of the land, thus improving the yield and quality of sweet potatoes.
