Do sweet potatoes need to be pruned? Will sweet potatoes grow again after the sweet potato vines are pruned?

Sweet potato vines are particularly easy to grow, especially in the rainy season when the soil is moist and the air temperature is suitable, which makes it easy for the vines to grow wildly. If you let them grow without taking care of them, only vines will grow but no sweet potatoes. We can control the vines by pruning, reduce the consumption of excessive nutrients, and allow nutrients to be supplied to the tubers, making the sweet potatoes grow better .

Sweet potato pruning time

Sweet potatoes need to be pruned several times. Generally, they need to be pruned during the first sweet potato swelling period, and the second time is two months after planting, when they will enter a high temperature and high humidity environment.

The vines grow vigorously and need to be pruned in time to control the absorption of nutrients. The third time is after ninety days, which is the second expansion period of the sweet potatoes. This is a critical period of sweet potato development and special attention should be paid.

Sweet potato pruning method

Sweet potato pruning is very simple. You only need to pinch off the tender yellow tips of the sweet potato seedlings, about six leaves. Do not water or fertilize after pinching off the tender leaves. The next thing to do is to sprinkle wood ash on the sweet potato seedlings. You don't need to use a lot of it, just enough for the wood ash to touch the wounds on the sweet potato seedlings.

After the wood ash comes into contact with the wound, it can accelerate the growth of a thin film on the wound of the sweet potato seedlings to prevent the wound from being infected by bacteria. Some particularly long branches can also be cut off.
