Potatoes are not perishable. However, storing it improperly in the winter can be troublesome. Potatoes do not like excessive moisture, high temperatures and react badly to cold.

All of the above makes storing a vegetable not so easy. Therefore, you need to know some of the nuances of how to properly store potatoes and which varieties are suitable for long-term storage.

This article describes in detail how to properly store potatoes and what to meet the requirements for long-term preservation of the vegetable.

Primary requirements

The main requirement is a dark and cool place. To keep potatoes longer, remember to ventilate and dry the room.

Vegetable growers advise to whitewash the walls and ceiling where the vegetable is stored. This is done to prevent mold from forming. Also check the room for holes and crevices, if there are any, be sure to seal them up.

Optimum content temperature

At what temperature are potatoes stored? Make sure that the temperature in the room does not exceed 4 degrees. But doing it below this mark is not worth it, since the potatoes will lose their taste. The maximum allowable temperature is 7 degrees. At 0 degrees and below, the vegetable freezes up, becomes sweet and unusable, and soon rots.


Humidity must be kept around 85%. Low or too high humidity can damage the potatoes. If the air is very dry, place containers with water, moisture will evaporate from them.


The tubers are stored in the dark. Be sure to hide the vegetable from direct sunlight.

How to increase the term?

The shelf life depends on many factors. This includes the variety of the potato itself, a properly selected and equipped storage space, compliance with all the rules. If you want your tubers to last longer in winter, consider this when planting the vegetable. For example, potatoes that grew in sandy soil will last longer than those that grew in loamy low-lying soil.

Late blight of plants also affects storage. Therefore, before digging out the tubers, the diseased tops are removed so that the infection does not get on the potatoes. If you follow all the instructions for the selection of storage space and strictly control the temperature, humidity and illumination, the shelf life of the vegetable will increase.

Will the potatoes last until spring?

You can store the vegetable for a long time. If you do this in a closed dark room, cellar or pantry, then it can lie until spring.

However, potatoes that have lay for more than three months are not recommended by experienced vegetable growers, at least without proper examination of their appearance.

Can you keep on sale until spring?

It all depends on the type of potato and the conditions in which it was grown and stored. Most varieties remain in good, marketable condition until spring. But it is better to sort out the potatoes before selling them in order to exclude damaged tubers from getting into the total mass.

What are the best varieties?

Almost any variety of vegetable is subject to storage, but it all depends on how much you plan to keep it in the pantry or cellar. If you decide to keep the tubers until spring, then choose mid-late and late-ripening varieties:

  • Zhuravinka.
  • Gull.
  • Yavir.
  • Gingerbread man.
  • Slav.
  • Atlant.
  • Asterix.
  • Saturn.

What is acceptable to store?

A vegetable is stored in bulk in cases where the harvest was small, because this method has a big drawback. If there are multiple foci of decay, you will lose most of the potatoes. Most people prefer to store in pallets or boxes, as it is convenient and spacious.

The container will provide ventilation and thus prevent rotting, disease and other storage problems. The boxes are easy to move and rearrange as needed. You can use bags, but made from natural materials. They are just as breathable as boxes.
