Storing Potatoes For Winter Use
For maximum harvest and good keeping quality, potatoes need time to fully mature. Potatoes should be dug 2 to 3 weeks after the tops die down. This will give the skins time to toughen up and become thick enough to protect them during storage. Once dug, potatoes need time to cure before storage. Don't wash them, but gently brush the excess dirt off, then allow them to cure for about 2 weeks at temperatures of about 45F, with good air circulation. Then you can store them all winter in a cool, dark location, with plenty of air circulation.
