Storage conditions for onions in winter
How and where to store onions from the garden? What preparatory measures must be taken to preserve the harvest? We will outline the main points in this chapter. We will talk separately about the storage of onions and green onions, since these processes are fundamentally different.
Storage in winter at subzero temperatures
Onions: different varieties
Onions can be of different varieties, each variety has its own name. Let's conditionally divide all varieties according to their appearance (the color of their husks):
- Yellow onions;
- White onions;
- Red onions.
Each type of onion has its own distinctive taste and quality characteristics. But the preparation for storage and the types of storage of such onions are basically very similar.
Usually onions are fully ripe by the end of August, and their green feathers begin to turn yellow. The onions are ready to harvest. To begin with, we dig it out of the garden, carefully digging it in with a shovel so as not to damage the bulbs and take it out of the ground. Next, we clean it from the ground, rinse it and dry it for two weeks in the fresh air or in a room with good ventilation. If the onion is completely dry, then it rustles when rolling and the onion neck becomes thin and dry, and makes a crackling sound. Next, cut the onion necks, leave the tails 3-4 cm in length. We also cut the roots without damaging the bottom of the onion itself.
All onions must be sorted. Select bulbs that are rotten, wet and damaged, that is, unsuitable for further storage. All strong onions with thin necks are ready for winter storage.
Storage of onions
At home, onions are stored at room temperature from 18 to 24 degrees in dark, dry places with good ventilation, with a humidity of 50-70%. It is desirable that this place is not in the kitchen, where the air temperature rises higher and frequent changes in humidity are possible.
You can also save the harvest at temperatures from -3 to +1 degrees in the basement, cellar, garage or balcony. In the case of a balcony, the storage space for onions during frosts must be additionally insulated.
Onions are stored in the refrigerator for only a few days in a peeled form, saving unused leftovers during cooking. The refrigerator is also useful for storing onion marinades.
A freezer for storing onions is used if the onions are peeled and chopped.
Onions are stored in various ways.
Storage of onions in bundles (pigtails)
You can braid the bow in braids and hang it in the room, this method is good for red and Crimean onions, but can be used for other varieties.
The bow can be stored in nylon tights or stockings
Onions can be stored in old tights and stockings, it is important that each bulb is separated from the previous one by a knot, so moisture will be removed from it from all sides.
Onions can be stored in nylon nets
Storing onions in nets is also common. This facilitates visual inspection of the onion when checking for rot.
- Canvas bags.
Storing onions in meshes
Onions can be stored in small canvas bags so that the onion layer is no more than 30 cm in them. This will exclude the lack of ventilation, create conditions for airing the entire mass of onions.
- Wicker baskets.
Storing onions in wicker baskets
Wicker baskets are well ventilated, which is important when preserving the harvest.
- Low boxes.
Storing onions in low boxes
You can store onions in low boxes, the onion layer should be no more than 30 cm.
- Cardboard boxes are also great for storing onions at home. It is recommended to make several holes in the side walls for ventilation.
Storing onions in cardboard boxes
- Do not store onions next to potatoes and beets, as they absorb moisture and deteriorate.
- It is important that the onion does not dry out. If in the storage place of onions the humidity is below 50%, then it is additionally sprinkled with husks, this helps it not to dry out.
- Very high humidity is also dangerous, for example, in a cellar or in a basement. It is advised to keep boxes with sawdust or ash in such rooms. This method copes well with excess moisture in confined spaces.
- During storage, it is recommended to sort out the entire onion several times, removing damp or rotten onions.
How to store green onions and leeks properly
Leek in the garden
Leeks and green onions are dug out of the garden. When stored in boxes in the cellar or on the balcony, the roots of the leek are trimmed, but feathers are left.
Green onions must be washed and cut off damaged and dry feathers, trimmed roots. After the onion must be dried from moisture. In this form, it is ready to be stored in the refrigerator.
Main ways to save
Leeks are stored in cold conditions, they can withstand temperatures down to -7 degrees. A cellar, balcony and refrigerator are suitable for this.
In the cellar and on the balcony, leeks are stored in boxes of sand.
Chives are kept fresh in the refrigerator and sliced in the freezer.
For storing green onion feathers in the refrigerator:
- plastic or vacuum bag;

Instructions for proper storage
Onion sets have a bulb size of 1-3 cm in diameter
There is a way to grow onions in two years. In the first year, onion sets grow from seeds - these are small bulbs with a diameter of up to 3 cm. Onion turnips are grown from it the next year. Sevok is stored in two ways: warm and cold.
The warm method means storage at a temperature of 18-24 degrees. If in the future you do not intend to grow a full-fledged onion from the seed, then you can burn the roots, so the onion will be preserved better. Sevok, like any other onion, keeps well at a moisture content of 50–70%. This storage method is suitable for seedlings with a diameter of 1-3 cm.
In a cold way, seedlings with a diameter of less than 1 cm are stored until spring at a temperature of -1 … +1 degrees, since at high room temperatures it will simply dry out.
But most often, such small bulbs are planted in the ground in the fall in October or November so that they have time to take root, but do not germinate.
Onions can be of different pungency, distinguishing between sweet, semi-sharp and spicy. Spicy onions are best preserved, they have the toughest husks. The easier it is to peel the onion, the softer the husk, the sweeter the onion.
Onions keep well under two temperature conditions:
- warm 18-22 degrees, humidity 50-70%;
- cold -1 … 0 degrees - for sweet and semi-sharp onions, -3 … -1 - for hot onions, humidity - 75-90%.
A warm regime can be created at home, but it is better not in the kitchen, where the air temperature often rises above 22 degrees and frequent changes in humidity are possible.
Cold mode can be created on the balcony, in the cellar, underground, garage.
When stored properly, onions can last up to 240 days in good condition.
White onions are the sweetest of all onions. It is stored less than others, and is more likely to rot. The storage area must be well ventilated and dry. Storage temperature 18-22 degrees and humidity 50-70%. However, even following the above rules will not give a long-term good result. White onions are not bought for storage, it is better to cook them right away. Due to its short shelf life, white onions are not very popular among gardeners.
Red onion, including Crimean (Yalta)
Red onions, like white ones, are sweet onions that, unfortunately, are not stored for long. The maximum is 120 days. The preferred storage method is at home. If possible, it is better to store such onions in bundles, Yalta (Crimean) onions are most often sold this way. And the advice from the sellers is always the same: you need to store the Crimean onions in a bundle, in a dry ventilated room.

Spread sand 5–7 cm thick on the bottom of the box, place the leeks vertically in it, cover the spaces between the heads with wet sand. Store in cellars at a temperature of 0 … + 4 degrees and a humidity of 80–85%. You can store the boxes on the balcony, but in this case, cover the onions with a warm blanket to avoid too low a temperature.
When storing leeks in the refrigerator, you need to cut the roots off. Pack the washed and dried leeks in plastic bags and put them in the refrigerator, in a compartment where the temperature is maintained at +5 degrees and above.

There is high humidity and low temperature - the necessary conditions for shooting a bow are created! Unfortunately, there is nothing to stop the onion sprouting, you can only sprout it and use its green feathers. You can also chop the sprouted bulbs and put them in the refrigerator or pickle them. For the remaining non-sprouted bulbs, the storage conditions must be changed. Keep it dry and warm, ventilated, or colder and less humid.
