Is it allowed and how much?
Onions in the kitchen can be at room temperature and low humidity , but such conditions are favorable for germination.
The temperature in the refrigerator is on average from +1°C to +3°C. This is the optimal indicator for storage, allowing you to keep onions without sprouting, and even keep them in a peeled state.
But there are also some disadvantages to using a refrigerator as a storage area for vegetables:
- short shelf life;
- it will not be possible to place large volumes;
- If storage is carried out without packaging, then the specific smell will permeate all the products.
In the vegetable compartment, onions are best preserved wrapped in a bag or placed in a plastic container.
The need to put onions in the refrigerator may arise when, after preparing a dish, there is excess product left, in some cases even already peeled and chopped.
If you properly package and store whole onions, they can last 30-60 days in the refrigerator.

When to harvest
How well the onions will be stored primarily depends on the right moment for harvesting.
It is believed that the optimal time for digging onions is from early August to early September. Naturally, the exact period depends on the climatic conditions of the region and whether the summer was dry or rainy. It is not difficult to determine whether a vegetable is ripe: its husk will easily come away from the bulb, and the feathers will dry out and turn yellow.
It is necessary to harvest on a dry day so that rain does not damage the plant. Try to select for long-term storage those specimens that do not have any damage, stains or traces of insects on their surface.
The vegetable must be ripe, otherwise it will quickly deteriorate during storage. An overripe plant should not be used for long-term storage: it begins to sprout roots and new green shoots within a month or two, which means it will become unsuitable for cooking.
Experienced gardeners know that late-ripening varieties are best stored. And early and sweet ones, such as the Yalta variety, are not very suitable for storing for the winter.
The new crop should be stored in a dry and cool place, away from direct sunlight. If the humidity is too high, the bulbs will quickly begin to rot.
You can also grow this plant for the next season using nigella - onion seeds. They are black in color, which is why they got their name. It is necessary to wait until the plant is completely ripe, and then cut off the inflorescences and leave them to dry. It is better to store arrows with seeds in a dry place: this way they will be easily separated.

How can you store onions in a cellar or basement for a long time?
Residents of private houses can store onions in underground storage facilities, but only if they are dry and equipped with an exhaust hood. A damp cellar is not suitable for storing these vegetables - in a cold, damp place the vegetable may begin to rot. The temperature in the cellar should not rise above 0-3°C, humidity - above 60-70%.
You can put the bulbs in wooden or plastic boxes, nets, baskets. There is no need to fill the container to the top; you should leave room for air circulation. For the same reason, it is not recommended to place boxes or stack nets on the storage floor; it is better to place them on racks or wooden pallets.
If there are not many onions and there is enough space in the cellar, you can simply lay them out on the shelves in a thin layer.
To disinfect onions, you can sprinkle them with crushed chalk or ash (200 g for every 10 kg of vegetables), and to reduce humidity, place containers with lime or small shavings in the cellar, or scatter them on the floor. The accumulated husks should also not be thrown away - they protect the vegetable well from waterlogging.
Whatever method of storing onions you choose, regularly (at least once a month) review and sort through the vegetable in order to promptly detect rotten, sprouted, soft or shriveled ones.
Remove and throw them away without hesitation, otherwise the rest of the onion will suffer. However, sprouted bulbs, if they are hard enough, can be used for forcing greens.
The damp but intact vegetable and the container in which it was lying must be dried again, the cellar ventilated, then the vegetables must be returned to their place. If everything is done correctly, the onion will last until spring, and some particularly successful specimens will last until summer.
Leek
A small amount of leek can be stored in the refrigerator. The compartment intended for vegetables is best suited for this.
When placed in it , excess leaves are cut off and distributed into polyethylene bags of 6-8 pieces per bag . Cellophane allows you to maintain the required level of humidity. Temperature suitable for storage is up to +5°C.

Prepare the container
The vegetable must “breathe” in it, that is, have access to fresh air.
Onions should not be kept in plastic bags because they do not allow air to pass through.
Wicker baskets, nylon stockings or tights, special nets, wooden boxes or cardboard boxes with ventilation holes on the sides are well suited for storage. Fabric bags are also suitable, just keep in mind that the height of onion stocks should not exceed 30 centimeters - otherwise the bottom layer will “suffocate”.
