How to prune sweet potatoes? How to prune sweet potato vines

Sweet potato pruning time

Sweet potatoes can be pruned 2-3 times during their growth period, mainly during the peak growth period. It is best to prune on sunny days and try not to do it on rainy days. Disinfection is required after pruning. Timely pruning can inhibit wild growth, accumulate nutrients to supply sweet potatoes, and also serve as a ventilation function.

Sweet potato pruning method

1. If the sweet potato vines do not grow wildly, you don't need to cut them. If they grow wildly or have some dry branches, you can cut them off. Cut off the side branches among the living branches to avoid wild growth and reduce nutrient consumption. You also need to observe the growth carefully and cut off the dense parts to increase ventilation and light transmittance.

2. Sweet potatoes grow relatively fast. If diseased and insect-infested leaves appear inside the plant, they need to be cut off in time and sprayed with pesticides for prevention and control. Otherwise, if the whole plant is diseased, it will affect the normal growth of the sweet potato and lead to reduced production.

3. In addition, after the sweet potato blooms, it will consume more nutrients, which is not conducive to the growth of its underground tubers. Therefore, as long as the sweet potato enters the flowering period, you can cut off the flowers on it to reduce nutrient waste and promote the growth of tubers.
