How to store onions

Asking the question of how to store onions, you first need to find out at what temperature and humidity this vegetable retains its properties. The optimum storage temperature for fresh onions is about 0 degrees. Air humidity can vary from 65% to 75%. But sometimes it is more convenient to freeze the onions and then add them to dishes as needed.

When storing onions indoors, you need to remember that they begin to sprout in late February – early March, and their taste deteriorates slightly during this period. Therefore, it is advisable to avoid high humidity and high temperatures, and place the onion crop in a cellar, basement, or refrigerator. Unlike some other vegetables, frozen onions are also suitable for cooking.

As for containers for storing onions, there are no restrictions here. Well suited for placement:

  • Shelves and shelves, inside which you can lay paper, straw;
  • Wooden boxes;
  • Perforated cardboard boxes;
  • Linen bags;
  • Nylon stockings;
  • Egg containers if not many onions have been purchased, etc.

  • In this case, a temperature of -3 to 0 degrees is created. It is believed that it is in such conditions that onions are stored for the maximum period.
  • In this case, vegetables are left at a room temperature of +18 +22 degrees and air humidity of about 60-70%.
  • This method involves the alternate storage of the harvested onion, first at room temperature, then – with the transition of winter – in low temperatures, and, when the thaw begins, again in a warm room.

The choice of onion storage depends on the type of onion. But in any case, the room must remain dry and well ventilated. And there should be no heating source or other vegetables next to the vegetables. If a box or box is chosen as a container, then its height should not be more than 30 cm.

Do not forget that throughout the entire storage period, onions are subject to periodic inspection and rejection of spoiled products. It is not recommended to close the boxes of onions, as this increases the level of humidity. And in such conditions, plants can begin to rot.

Storage of onions in different rooms: requirements and features

How to store onions in an apartment – this question is asked by housewives after harvesting a large harvest of vegetables or buying food on the market. Vegetables can be placed in the basement or cellar in any way you choose:

  • Hanging special nets with bows or bundles from the ceiling;
  • In wooden crates, pallets or in bulk in one layer.

Onions will be able to stay all winter long without losing their properties, even if the temperature drops slightly below zero. Red, or Yalta, onions are well kept hanging, but slightly shorter in time compared to onions.

However, it is important that there is ventilation in the basement or cellar to allow air to flow in and out. It is also important to take care of thermal insulation. If this cannot be done, then during severe frosts, you can cover the vegetable with a blanket or straw. On average, onion storage in a basement or cellar is 4-5 months.

If there is no room for onions, a refrigerator is well suited for storage. In it, the vegetable will retain its appearance, taste and benefits for a month. And then, under the influence of humidity and low temperatures, the product acquires an unpleasant aroma. It may also develop dark spots, mold or decay marks. Do not leave onions in a plastic bag for a long time, as this vegetable must breathe. Storing onions next to potatoes is also unacceptable: the latter releases moisture, which negatively affects the condition of the bulbs. Conversely, chives keep well in a plastic bag in the refrigerator.

In the process of creating dishes, it is often necessary to store the peeled onion, and therefore it is important to know how long to store the onion without the husk. An excellent option would be to place the onion in a plastic container – with a cut towards the bottom. In such a container, the onion itself will retain its freshness and at the same time will not saturate other products stored in the refrigerator with its sharp specific aroma. You can add salt to the container to extend the shelf life of the peeled and cut onions. If you need to keep finely chopped onions, it is best to place them in a plastic or paper bag, and then in the freezer. After thawing, the product can also be added to salads, appetizers, soups and main courses. But you need to remember that onions cannot be stored in the refrigerator for longer than 12-24 hours. Otherwise, after that, it will lose its properties, and its taste will become less pronounced.

The pantry in the house is another place for storing onions. In such a room, vegetables can be placed in wooden boxes or boxes. If there is no pantry, which is quite possible when a person lives in an apartment, then you can place the bow on the balcony. But only until the first frost. You also need to remember that sudden changes in temperature negatively affect the condition of the bulbs. It is better to observe the optimum temperature – + 7 + 10 degrees. Alternatively, store the onions at room temperature, but not peeled.

Or, due to the loss of moisture, the onions become dry and shriveled and do not keep well, compared to specimens harvested on time. You also need to ensure that the onions are not damaged by pathogenic fungi and bacteria.

The most suitable season for harvesting garlic and onions is July. At this time, the plant stops growing, but at the same time both green and dry leaves remain, and the dry husk of the bulb is also visible. When there are about two weeks left before harvest, you need to stop watering the vegetables. It is not recommended to pull the bulbs out of the ground, as they can be damaged, and such specimens cannot be stored for a long time. It is best to dig up onions.

After the vegetable has been dug up, it is left to dry in the sun. You can spread the crop right on the garden bed where it grew, if there is no rain. Thus, the plant can lay for 10-14 days until its husk hardens and takes on a golden, dark red or brown hue, depending on the variety.

Harvesting onions in the rain is not recommended. But if there is no other option, at the end of the work it is necessary to ensure that the vegetable is kept in a warm room, so that all excess moisture is gone and the onion does not start to rot. This is especially important if you plan to store crops for a long time in a basement, utility room, storage room, garage, or just under a shed. After initial drying, re-dry in a warm room. In order not to lose the harvest, you need to sort out the bulbs in advance and remove those that have changed their smell, color, or they have become too soft, watery.

The room in which the onions will be kept must be well ventilated, clean and a certain temperature regime must be maintained here. Only clean containers should be used to place onions.

  • It is necessary to peel the onion from the ground but do it very carefully so as not to damage the protective shell.
  • Drying under suitable conditions and trimming the roots. Carrying out this work, you cannot touch the bottom and you need to cut off the stems completely, leaving a tail about 5 cm long. However, if you plan to tie the onion, then the tails can be much longer.
  • To avoid onion sprouting, you can roast the roots or process them with a special paste based on lime.

  • Rot on the side of the heel caused by Fusarium fungus. It is also considered to be the main disease of this vegetable and can appear during the growing season. The fungus enters vegetables through contaminated water, soil, or along with infected specimens. To make the onion less susceptible to infection with high-intensity onion rot, you should not plant it on swampy soils, and you need to take only health seeds. And during cleaning, make sure that there is no mechanical damage to the specimens. Otherwise, it is better to eat such a product immediately, since it will not be able to lie for a long time.
  • Rot is white. This disease can be recognized by its specific color and texture. White rot similar to cotton wool appears on the bulbs. It spreads through contaminated water or soil, or through diseased seedlings. To avoid infection with such a disease, it is necessary to properly store seeds and grown specimens.
