The key to storing potatoes for a long time is to store the potatoes in a cool, dark and dry place.
Potatoes need airflow to prevent the accumulation of moisture, which can lead to spoilage.
The best way to allow free circulation of air is to store them in an open bowl or paper bag.
Do not store them in a sealed container without ventilation, such as a zipped plastic bag or lidded glassware.
The key is to store potatoes in a cool dry place, like in the cabinet of a pantry, in a paper bag or cardboard box.
It's important to keep potatoes at the cool, ideal temperature (but not, surprisingly, the fridge) to prevent them from turning green, getting soft spots, or pre-maturely sprouting.
Potatoes are good for up to 5 weeks although they may last a bit longer depending on how you store them.
When potatoes are stored in a cool dark place the potatoes will last longer.
If the potatoes start going bad you can cut the bad parts of the potatoes off and eat the rest.
The shelf life of potatoes is 5 weeks and after 5 weeks the potatoes will go bad and start to smell bad.
If you want to keep the potatoes longer store the potatoes in a cool dark place or in the refrigerator.
The potatoes will keep in the refrigerator for 4 months before they spoil and start to smell.
If you want to keep the potatoes longer than 4 months you can freeze them but they will become soggy once you freeze the whole potatoes.
I will sometimes freeze extra potatoes whole and use them in soups and stews where the sogginess of the potatoes when thawed is not a problem.
For fresh potatoes it's best to buy them fresh and then eat them within the month.
Or cut the potatoes up to make fries and then blanch the cut up potatoes and freeze them so they will always be available and ready to deep fry.
