Burlap bags, wicker baskets and paper grocery bags are great ways to store potatoes long term. If kept in a dry dark place, potatoes can last two to three months from harvest.
Potatoes should be stored away from light, moisture and heat. Any of these conditions can cause potatoes to begin sprouting or rotting. RealSimple.com advises against storing potatoes in the refrigerator because temperatures below 50 F cause the starch to turn to sugar. Also, do not store onions with or near potatoes. Off-putting gases from onions can accelerate potato rot. Alternative methods to store large quantities of potatoes include freezing, canning and dehydrating cooked potatoes.
