Characteristics of the Senshui onion variety

The Senshui winter onion has good quality characteristics. Vegetable growers from different regions note its stable high yield, unpretentiousness and resistance to diseases.

Winter onion varieties are capable of providing a quick, high-quality harvest. It is harvested 2 months earlier than in the spring planting of spring varieties.

The yield of the variety is 4 kg of heads per 1 sq. m landing area. The weight of one onion reaches 150-180 g, with good agricultural technology, heads are harvested of 250 g each. The pulp is juicy, white. You can increase the yield by competently regulating the watering of the variety.

  1. Early ripening. The feather is ready for culinary use in early spring; when planted in the second year, the bulbs are ready to be harvested in the middle of summer.
  2. Frost resistance. The Senshui variety tolerates a drop in temperature to -15 ° C.In addition, even lower temperatures are not harmful if severe frosts are short-lived.
  3. Productivity, which is considered high enough for winter varieties.
  4. Taste qualities make it possible to use the vegetable not only in the preparation of fresh dishes, but also to preserve the bulbs.
  5. Storage and transportability are of a high standard. The Senshui lays up to 6 months without losing its qualities.
  6. Not subject to shooting.
  7. Unpretentiousness. Care consists of a short list of activities. And in the spring, the bulbs do not even need watering.

The disadvantage is the lower yield compared to spring varieties. Although a careful choice of planting material greatly increases this indicator. The second disadvantage is a short shelf life. But all early-ripening bulbous varieties have this drawback.

Planting and caring for onions

Planting winter onions has its own characteristics. For winter varieties, all recommendations must be carefully followed. Only in this case, you can count on a decent result. The following will present the basic requirements for planting and caring for the Senshui bow.

Onion planting dates

The Senshui winter sevok is planted in terms that depend on the climatic characteristics of the region. If these are the southern regions, then the optimal period is November. For the northern ones, the dates should be shifted by a month and a half and planting should be carried out in September or October.

Important! You need to finish planting before the frost begins.

Frozen soil will harm the planting material, and early planting can lead to premature germination.

Garden bed preparation

The place for the beds should be chosen carefully. The Senshui prefers a sheltered and well-lit area. The lowland is not suitable due to the accumulation of water when the snow melts. In such conditions, the bulbs begin to heat up quickly.

The garden bed is prepared in compliance with the crop rotation. Senshui can be planted no earlier than 5 years after the previous cultivation of legumes, bulbs and potatoes. Ideal predecessors are beets, carrots, cabbage, greens.

Preparation begins 2 weeks before the scheduled planting date. The soil is dug up with the simultaneous introduction of humus and mineral fertilizers, then the bed is left for the soil to settle.

Before planting, the bed is sprinkled with wood ash and a ridge 20 cm high is formed.

Planting onions

No preliminary preparation of the planting material is required. Sevok does not need to be soaked or trimmed.

In the prepared bed, you will need to make furrows. The depth of each is no more than 5 cm, and the distance between them is about 15 cm.

The Senshui onion set is placed along the furrow. It is important at the time of planting to ensure that the neck is 2 cm below ground level.The distance between the two bulbs is maintained no more than 15 cm.

From above, the seedlings are covered with earth, then with humus. Be sure to insulate the garden by laying a layer of spruce branches or sawdust. You do not need to water immediately. You can slightly moisten the garden bed after 10 days in dry weather.

Growing onions

Senshui onion care begins with the onset of spring. With a stable heat, the bed is freed from the covering mulch, then fertilized with urea. For 1 sq. m will need 10 g of the substance.

Then the soil is loosened and sprinkled with a thin layer of wood ash. After the formation of 4 leaves, the culture is fed with phosphorus (20 g per 1 sq. M) and potassium (10 g per 1 sq. M). The optimal method of fertilizing Senshui onions is considered to be watering with liquid solutions.

The beds are watered no earlier than May and as needed. Each watering is completed by gentle loosening.

Harvesting and storage

Ripening of the variety begins in early summer. Depending on the region of cultivation, the harvest period comes in June or July. For 2 weeks, stop watering and loosening. During this period, the heads gain maximum weight, and their scales dry out. Therefore, you should not stimulate the growth of greenery with such actions.

Cleaning begins before the leaves turn completely yellow.Otherwise, after the first rain, the Senshui will begin to form new roots.

The bulbs are carefully pulled out of the ground, laid out on the ground to dry. In dry weather, drying lasts a week. In addition to drying, the sun's rays have a disinfecting effect. After a week, the crop is sent under a shed and kept there for 20 days. These heads are better stored. During the rainy season, the crop is transferred to a well-ventilated, but closed room for drying.

Then a bulkhead is carried out. Intact, dense bulbs are laid for storage. The leaves are cut at a height of 5 cm from the neck. Then the roots are cut without touching the bottom. Place the Senshui in nets, baskets or boxes with ventilated walls. Many people make pigtails that make it easier to control the condition of the bulbs during storage.

Onion breeding methods

The Senshui onion variety belongs to hybrid forms, therefore it multiplies by planting sets. If you want to grow the planting material yourself, then the seeds should be purchased in specialized stores. Collecting seeds yourself is not recommended. With this method of propagation, hybrid varieties do not retain their characteristics.

Diseases and pests, methods of control and prevention

Before planting, the beds must be treated with tobacco thrips, nematodes, and onion flies. During the period of growing winter onions, it is necessary to regularly inspect the plantings. Before harvesting, the Senshui may be attacked by insects. Gardeners advise to stock up on "Aktara" or "Medvedoks". From folk remedies, they use infusions of marigolds, alkaloid lupine. Additionally, they frame the onion bed with rows of marigolds.


The Senshui onion is an excellent variety for private growers and farms. The onion is perfectly adapted to the climate of the middle zone, tolerates winter, gives an early harvest, and has a good taste. The ability to transport allows you to sell crops in other areas without loss.

And a little practice:


Perevalova Tamara Petrovna, 47 years old, Novorossiysk
For a long time we have been growing the Senshui variety for commercial purposes with my husband. I note right away that this onion has an excellent taste and is sold out without a trace. Therefore, it does not even require large storage areas. When growing, we must carry out all measures to prevent diseases and pests. Winter onions attract many parasites who want to feast on early crops. Otherwise, it is a completely unpretentious variety that does not require constant attention.
Sklyarov Viktor Stepanovich, 55 years old, Astrakhan
Our entire family is very fond of the Senshui hybrid onion. We plant quite a bit, but enough until January. I like the taste and aroma of the heads. Even children enjoy eating fresh onions that are not very bitter. Keeping quality is lower than that of spring, but varietal characteristics are better. In the spring we sow marigolds around the ridges, in the fall we alternate planting onions with carrots. The onion fly has diminished a lot.
