The onion is characterized by abundant thickening of long feathers, which extend to a height of 70-80 cm, as well as a developed rhizome. The leaves of the plant are uniformly gray-green or pale green without anthocyanin coloration. On the surfaces of flat onion leaves there is a pronounced waxy bloom. The false stem is endowed with a weakly expressed bulb.

Characteristics of the appearance of plants and bulbs

This variety is valuable for its bulbous bleached leg and thick and fleshy feathers. The snow-white bulb is characterized by a fleshy, tender, moderately dense and juicy consistency. On average, the length of the bulb reaches 20-30 cm, and the diameter is about 4-5 cm. The structure of the bulb is of medium density, consisting of fleshy scales, tightly adjacent to each other. The total weight of the plant is usually 300-400 grams.

Of particular value is the onion pulp, which contains a high content of vitamins of group B, A, E, ascorbic acid, beta-carotene, as well as phytoncides, some proteins and fats. The high iron content is also worth noting.

Cut onions without significant losses transfer transportation over long distances, and can also be stored for a long time. It is characteristic that during transportation the leg does not darken, does not crack. For storage, vegetables are laid out vertically, and then covered with sand.

Purpose and taste

The Dutch onion stands out among its relatives for its excellent taste. Its taste is balanced - low pungency, subtle sweet notes and a light onion aroma are perfectly combined in the snow-white pulp.

Mass harvesting begins between July and September. To carefully remove the onion, you need to make a small dig and pull it out gently. The length of the feathers is kept at the level of 20 cm from the branching, and the rest is cut off.

This onion species is very productive. An average of 3.1 kg of vegetables is cut from 1 m2.

Planting dates with seeds, seedlings and seedlings

Sowing seeds for seedlings is carried out in February-March, and transplantation to a permanent place of growth is performed after 60-65 days.Onion seeds are sown in open ground exclusively in the southern regions, when the air and soil are sufficiently warmed up - the end of May. Sevkom planting is also carried out in the warm season: late May - early June.

Growing and care

Onions are grown by seedling and seed methods. Seedlings are grown in a greenhouse. The seeds are buried in the prepared substrate by 2 cm. Germination occurs after 2 weeks. The distance between the rows is 4-5 cm. The optimal temperature regime is +20.22 degrees. Bushes ready for transplanting should be strong, with 3-5 true leaves and a false stem diameter of up to 6-8 mm. Landing is carried out in one-line rows or two-line ribbons according to the scheme 25x50 and 30x60 cm.

When planting with sevkom, the scheme of 7-10x50-60 cm is observed. Seeds are planted in open ground in conditions of stable heat. Onion care includes: watering every 3-4 days with warm water, weeding and loosening, applying dressings 2-3 times per season, hilling 2 times in the second half of the growing season to obtain bleached onion legs, prevention of viruses.

Since the onion is an unpretentious and cold-resistant plant, it can be planted both in spring and autumn. It is necessary to properly prepare the planting material, competently prepare the garden bed and determine the timing of planting.

To grow a large and tasty onion crop, you need to take good care of it from planting to harvesting. Watering is an important part of outdoor crop care. Thanks to timely watering, the onion will be able to grow normally, form a bulb, and grow greens.

Soil requirements

Onions prefer medium loamy fertile soils with good drainage system and a neutral reaction. The soil is preliminarily well loosened, enriched with nutrients, moisturized.

The bow is not as unpretentious as it seems. For good growth, you need fertile soil, quality care and nutritious fertilizers. Without top dressing, the bulbs will grow small, and the greens will not be lush. At different stages, it should be fed with different substances. The vegetable needs organic and mineral feeding.

Planting carrots nearby, the aroma of which repels pests, is an excellent tool in the fight against onion flies.

Despite the fact that the onion is a very useful plant, capable of repelling and killing many microbes and bacteria, it itself is often damaged and suffers from various misfortunes. Diseases and pests of onions can significantly reduce the yield. It is necessary to correctly determine the presence of this or that disease and take appropriate measures in time.

To get a good harvest, you should not only properly care for it, but also harvest it at a certain time. You can remove the onion from the garden only after it is fully ripe.Collecting bulbs in the middle lane usually begins in August, closer to the middle of the month.
After harvesting the onion, it is important to preserve it as long as possible, without losing quality. For this, the raw materials must be properly prepared. You can store onions in different ways. It is important to observe a certain mode of temperature and humidity in the room.
