- powerful root system;
- thin, golden scales;
- long-term storage;
- taste qualities;
- early ripening;
- undemanding to planting and care;

The disadvantage of most gardeners consider low productivity compared to spring plantings.
Planting and caring for winter onions Radar
Planting a winter onion Radar is carried out subject to simple rules. These are planting dates, digging beds and preparing planting material.
Planting dates for onions
Sevok can be planted throughout October. The term is determined by climatic conditions and the region of growth:

Timings of planting Radar winter onions in Siberia
The harsh Siberian weather causes a lot of trouble for gardeners. Many of them do not dare to plant winter onions in their personal plots. But thanks to its cold resistance, Radar is ideal for the local cold and snowy climate.
To harvest an early harvest, sevok is planted in mid-October, early November.
Preparation of beds
The yield depends on the right place. The beds are made in an open, flat, lit place without drafts. It is inefficient to grow sevok in a lowland, since with the advent of warming, the beds will be in water, which will lead to the death of the crop.
The beds are prepared in advance, a month before planting. After digging, the soil is fed with complex mineral fertilizers and disinfected with a copper-containing solution. For top dressing, it is better to use wood ash, humus or rotted compost. It is not recommended to fertilize the soil with fresh manure, as the plant will grow green mass and make the bulb loose. Such a vegetable is not subject to long-term storage.
Due to its unpretentiousness, the variety can be planted in any soil.
Bow Landing Radar
The variety does not require much care. To get a rich harvest, care and observance of simple rules are necessary:
- Onion sets Radar are planted in rows, to a depth of 4 cm, so that the neck deepens by 2-3 cm. The interval between the bulbs should be 10 cm, and between the rows 20 cm.
- When using a shallow set, the depth should be 2-3 cm, when planting large specimens – 3-4 cm.
- To have a high yield, planting is best done in a checkerboard pattern.
- Planting material is covered with soil and mulched. Watering is not required after planting.
- Dry leaves, straw, humus, tops or spruce branches are used as mulch.
Growing winter onions Radar
Growing sevok is simple, and even a novice gardener can handle it. For successful cultivation, you need to listen to the recommendations of experienced gardeners:
- In the spring, the mulch is removed from the beds so that the soil does not overheat.
- Watering is carried out as needed, after which the soil is loosened and weeds are removed.
- The first feeding with ashes is carried out immediately after the snow melts.
- The second top dressing is carried out after the appearance of foliage. For this, growth stimulants and immunomodulators are used.
- Once every two weeks, preventive measures against diseases and pests are carried out. To do this, the plant is treated with fungicides or copper chloride. If the air humidity is increased, the treatment is carried out once every 7 days.
Mistakes that gardeners make when growing Radar onions:
- incorrectly chosen planting date – winter onions germinate in April;
- with an incorrectly chosen place and abundant watering, the bulbs rot;
- the bulb does not germinate if the planting depth is more than 10 cm.
Collection and storage of crops
The growing season for Radar onions is 250 days. The crop is harvested only after the bulb has formed. The degree of maturity is determined by the loss of elasticity and yellowing of the leaf, as well as after the head is overgrown with light golden scales.
The crop is dug up in dry weather and left for 2-3 days in the open sun to dry. To preserve freshness for a long time, it must be thoroughly dried. If harvesting is carried out in wet weather, the crop is washed and peeled. Feathers, roots are cut off and cleaned to dry in a well-ventilated area. As soon as the onion neck dries, it is folded for long-term storage.
How is the bow Radar stored?
Collected and dried onions are sorted out, unripe and onions with a thin juicy neck are used first, since such onions will not be stored for a long time.
There are several ways to store vegetables:
- In boxes or bags.
- In women’s stockings.
- In a braided braid. Onion scythe will retain freshness for a long time and will become a decoration of the kitchen.

Ways to propagate onions
Dutch culture can be grown through seeds. Planting material is sown in August on a prepared, fertilized place. Seeds are sown according to the 1×10 scheme, to a depth of 3 cm. The earth is shed and mulched.
Seeds are harvested in the spring, dried and put away for storage. Self-obtained seed can be planted before winter for an early harvest.
Diseases and pests, methods of control and prevention
As can be seen from the characteristics of the variety, Radar onion sets are immune to many diseases and pests. But in order to get a generous harvest, common diseases cannot be allowed to join. The main threat to the Radar onion is the onion fly and downy mildew.
Lukovaâ flies
For treatment, chemical and folk remedies are used:
- Drug treatment Whites, Fly-eater or Karat Zeon.
- Next to the plant, you can plant carrots, marigolds, valerian, mint or tomatoes. The smell of these plants repels insects.
- Before planting, seedlings should be treated in a weak solution of potassium permanganate.
- Crop rotation will help rid the plant of the onion fly.
Peronosporoz
You can determine the disease by the formation of gray plaque on the foliage. Without treatment, the entire feather is affected and the plant dies. The disease quickly spreads to healthy plants, resulting in reduced yields, poor bulb quality and reduced shelf life.
Preventive measures against downy mildew:
- observance of crop rotation;
- the use of high-quality planting material;
- processing sevka;
- once every 7 days, powdering the soil with wood ash;
- once a month, spraying plants with Bordeaux liquid.
