How do you turn sweet potato vines during cultivation? Should it be done during the rainy season or during drought? We ask experienced gardeners to help explain.


Because sweet potato is a vine-like herbaceous plant, the vines grow prostrate along the ground, and secondary roots form at the stem nodes in the soil. Therefore, the yield of sweet potatoes is related to the tubers; the larger the tubers, the higher the yield. Moreover, the size of the tubers is not only related to fertilizer and water, but also to whether the vines are turned, and how much they are turned. Therefore, Zhongdiwang has compiled the circumstances under which sweet potato vines need to be turned and when they do not need to be turned, listed in detail below for gardeners to reference.

  1. When there is sufficient moisture, sweet potato vines need to be turned:
Because secondary roots form at the stem nodes of the sweet potato, these secondary roots can absorb large amounts of nutrients and water, making vegetative growth vigorous and causing the vines to grow excessively, while inhibiting the reproductive growth of the tubers, which leads to slow tuber growth.

       At the same time, when there is sufficient moisture, the secondary roots of the sweet potato will also produce small tubers, causing insufficient nutrients and resulting in the phenomenon of too many tubers being formed and the tubers not being large, thus leading to low sweet potato yield. In this situation, the sweet potato vines should be turned frequently to control the formation of secondary roots, inhibit excessive vine growth, and thereby provide more nutrients for reproductive growth, so that the tubers grow quickly.

  2. When there is drought and a lack of water, sweet potato vines should be turned less or not at all:
The sweet potato vines should be turned less or not at all, so that secondary roots can form at the stem nodes, providing more water and nutrients for the growth of the sweet potato, which is beneficial to the growth and survival of the plant. Otherwise, it is not beneficial to the growth and survival of the plant, and the sweet potato yield will decrease.
