Storing potatoes properly can extend their shelf life up to three months, saving you money and reducing waste. Expert advice includes choosing a cool, dark, and well-ventilated place, such as a basement or root cellar. Maintain a temperature of 7-10 degrees Celsius and humidity around 90% to prevent drying out and sprouting. Store potatoes in wooden crates, sacks, or perforated plastic bags to protect them from light. Keep them away from onions to avoid gas exposure that accelerates sprouting. Following these tips will ensure your potatoes stay edible and fresh for longer.
