Planting sweet potatoes is mostly carried out in the spring in April and May, and low temperatures in the northern regions will be delayed until mid-May. When planting, you should first organize the plot to ensure that the soil is deep, loose and fertile. The seed plots can be planted in after treatment. Sweet potatoes have a strong sprouting ability and will soon grow seedlings. When the seedling grows to 5 inches high intercept the leaves, directly transferred to the soil, soon can grow small white roots, and then transplanting on the line.

A, planting time

Sweet potato leaves are usually harvested in the fall. Planting time is mostly in the spring, specifically between April and May. The low temperature of the north is mostly in the middle of May. Suitable for sweet potato seed sprouting temperature is between 15 degrees to 25 degrees, the temperature is suitable for sprouting speed will be faster.

Two, planting method

1, organize the plot: planting sweet potato to choose the soil layer is relatively deep plot, and to facilitate drainage, loose, fertile, so that the plot is conducive to the late growth, management is also convenient. Therefore, it is recommended that before planting deep turning treatment, but also apply the right amount of fertilizer, improve soil fertility.

2, sowing and leaf-cutting: the treatment of the plot can be sown. Directly the seed can be planted quickly. The temperature is suitable, and the seedlings will soon emerge. When the seedlings grow to 5 inches, you can cut the leaves. Cut directly at the fork of the seedlings. There is no need to fertilize later and new ones will soon sprout. The cut off part is then inserted into the soil with enough nutrients can soon continue to sprout and grow.

3, timely transplantation: planted sweet potato leaves if the top sprouting small white roots can continue to transplant planting. Note that after planting to give sufficient light, fertilizer, so that more vigorous growth.
