Yes, sweet potatoes should be stored in a cool, dark, and well-ventilated place to prevent them from sprouting and to prolong their shelf life.
Sweet potatoes are best stored in conditions that mimic their natural growing environment. Exposure to light triggers sprouting, which depletes the sweet potato's nutrients and makes it less palatable. A dark environment, such as a pantry or root cellar, helps to prevent this. Furthermore, a cool temperature (around 55-60°F or 13-16°C) slows down the metabolic processes that lead to spoilage. Good ventilation is also crucial to prevent the buildup of moisture, which can encourage mold growth and rotting. Avoid storing sweet potatoes in the refrigerator, as the cold temperatures can negatively affect their flavor and texture, causing them to become hard and develop a bitter taste. Instead, find a cool, dark, and dry place where they can breathe.
Don't store sweet potatoes near apples or bananas. These fruits release ethylene gas, which can accelerate the ripening and spoilage of sweet potatoes.
