The ideal storage temperature for potatoes is 40ºF, which is on the warm end of most home refrigerators, and they don’t like light, which can cause them to turn green. Basements or cellars usually provide perfect potato-storage conditions that will keep them from rotting for between 2 and 4 months. Keep them away from onions and apples, wherever you store them, as both emit gases that speed up the ripening process.
Bonus tip: Sweet potatoes don’t last very long in storage, so eat those within a week of purchase.
