Pruning Sweet Potato Plants
Avoid Excessive Pruning: Sweet potatoes store energy in their vines, and excessive pruning may reduce the yield of tubers. It’s generally best to allow the vines to grow freely, focusing more on managing their spread rather than actively pruning.
However, there are a few tips related to managing the vines and foliage:

Remove Excessive Growth: If the sweet potato vines become overly vigorous and start to take over your garden space, you can trim or gently remove some of the excess growth. This can help maintain a more manageable and tidy garden.
Harvesting Greens: While not exactly pruning, you can harvest sweet potato leaves for consumption. The young leaves are edible and nutritious. Harvesting them won’t negatively impact tuber development, and it can be a way to enjoy fresh greens from your garden.
Controlled Growth in Containers: If you’re growing sweet potatoes in containers and want to control their size, you can trim the vines periodically. This is more about managing the plant’s size in limited space rather than traditional pruning.
Remove Yellow or Diseased Leaves: Regularly inspect your sweet potato plants for any yellow or diseased leaves. Removing these leaves can help prevent the spread of diseases and maintain the overall health of the plant.
Remember that sweet potatoes thrive with ample foliage, as it contributes to the plant’s ability to capture sunlight and produce energy for tuber development. If you do decide to trim or remove some foliage, do so sparingly and avoid heavy pruning that could significantly impact the plant’s overall growth and productivity.
