Optimum terms for landing
Since the weather in the Urals is unstable, specific dates are difficult to articulate. The main condition is to monitor before landing that the temperature does not fall below 5-10ºС for several days. The average landing time is the first decade of May.
Important! Bow sevok categorically can not be planted in a cold ground.Choosing the time of planting, you need to focus on the growing season depending on the variety. In early varieties it is 90 days, the mid-season - 110 days, late - 120 days. So, now it is known, when to plant onion sets in the Urals, let's proceed to the preparation, planting and care.
Choosing a place
To obtain a good harvest, it is important to responsibly consider the choice of a place for planting.
Lighting
Well-lit areas are suitable for onions, preferably on higher ground.
The soil
Preference should be given to loamy or sandy soils with neutral acidity. In the autumn, before planting, it is recommended to introduce humus.
Predecessors
As a predecessor, it is better to choose crops such as white and cauliflower, cucumbers, radishes. It is better not to plant onions in the same area two years in a row. Bad predecessors are carrots, radishes, celery, greens. 
Site preparation
For planting onion seed in the Urals, it is important to properly prepare the site. In the spring, the area where the sevines are supposed to be planted should be dug to a depth of 15 cm. Then beds of about 60 cm wide are arranged, and ridges are formed on clayey soil. When sandy soil fit and grooves. Next, they must be covered with a film to warm the soil and do not remove it until planting.
Did you know? Onions cause tearing due to the substance propanethiol S-oxide, which is released when sliced.
Requirements for planting material
Preparation of planting material consists of five stages:
- quality control and sorting;
- drying;
- warming up;
- disinfection and soaking;
- washing and airing.
First, onions intended for sowing, it is necessary to sort out and throw away rotten or withered specimens. Then the onions are sorted by size and first planted one that is larger. Next, the onions are dried in a warm, protected from moisture place. To avoid early formation of arrows, sevok heated near the batteries.
For hardening the future harvest, the bulbs are soaked in water with a temperature of 40-50ºС for about 15 minutes, and then for the same time in cool water. After that, onions are placed for 6 hours in a solution of mineral fertilizers.

Scheme and depth of landing
The distance between the bulbous beds should be about 20 cm. The bulbs are planted at a distance from each other up to 20 cm. It should be planted in such a way that the tail looks out above the surface.
Important! If the bow is planted deeper, then its growth will go to the arrow.
Competent care-a good harvest
For successful cultivation in the harsh conditions of the Urals, you must adhere to the recommendations for care.
Watering, weeding and loosening
In the first two weeks after sowing and for three weeks after emergence, the onion needs to be plentiful in watering, since it is at this point that the root system forms. Further, the abundance of irrigation should be reduced. You also need to timely remove weeds and loosen the soil, to mulch it.
Top dressing
When planting seedlings in the grooves make compost. In the summer the beds are watered with organic fertilizers. 
Pest and disease control
One common pest is the onion fly. The larvae are dangerous, they penetrate into young bulbs and eat them from the inside. A sign of damage to fly larvae is yellowing and drying feathers. For the prevention of sevok before planting disinfect. Also, the soil is treated with a solution of salt (300 g per 10 l of water).
Important! The onion fly does not tolerate the smell of carrots, so often carrots are planted next to the onions to fight it.Another onion pest is thrips. These are very small brown insects. Affected shoots turn yellow and die. In country conditions they are scared away by ashes, tobacco, carrots.
Onions can strike powdery mildew. In this disease is observed:
- withered leaves;
- vague pale spots on the shoots;
- raid on feathers;
- yellowing and drying greens.
When detected, the affected shoots are removed. Plantations sprayed "Oxyhom".
Gray rot is formed due to the presence of spores of the fungus Botrytis, manifested during storage. The treatment is carried out with the help of the drugs "Bravo", "Switch" and "Quadris". Folk methods of struggle - this is a restriction of nitrogen supplements and strengthening of potash-phosphorus. This will help speed up ripening and premature closure of the cervix, as a result of which the spores do not penetrate the pulp. Another similar disease is bacteriosis. Methods of control are similar to gray rot. 
Harvesting and storage of the crop
If you notice that the new leaves have ceased to appear, and the old ones are dying off, this indicates the need for harvesting. For better drying, it is recommended to collect onions in windy and dry weather. After the onion dries out during the day in the air, it is moved to a ventilated room for 2-3 weeks. It should not be allowed to dry out - the scales will crack and go, such a bow will not be stored for a long time.
Did you know? The largest onion weighing 8.49 kg was grown in Leicestershire, UK.Store the crop in dry and cool basements. With a lack of moisture and elevated temperature, the crop will shrink, and with an excess of moisture it will rot.
Growing onions in the Urals does not represent special difficulties. The main thing is to choose the right time for planting and adhere to the elementary requirements regarding care.
