Potatoes are tubers that survive best in a humid location because they are 80 percent water. A common mistake that many people make when storing potatoes is not keeping them in an area that is particularly humid. If too much cool air gets to the potatoes, they can begin to rot quickly. When you purchase potatoes are your local grocery store, they come in plastic bags with tiny holes. These holes offer ventilation for the potatoes to be stored in warm areas of households. It's important that after you harvest that you store your potatoes in the same way.
Leave your potatoes out in the sunlight for at least two hours after you harvest them. This will give your potatoes time to dry off from being in moist soil and help the potato skin to harden.
Brush off any soil that remains on the potatoes. Inspect the potatoes carefully to see if any have been infected by pests for best potato care. Use any potatoes that you suspect of infection immediately to avoid storing such potatoes.
Place the potatoes in a sack that has holes that are 1/4 inch in diameter. Never wash the potatoes before placing them in the sack. You can use an old potato sack from a store or use a large plastic bag.
Store potatoes in a location in your kitchen or pantry where no direct sunlight reaches. If the potatoes become exposed to light for a long period of time, they can start to turn green.
Continue storing the potatoes for up to a month or use them at anytime during the storage period. Take your potatoes out and inspect them again. You can now prepare you potatoes for use by washing them well and piercing them all around with a fork before baking or boiling.
