Nowadays, many housewives grow several varieties at once in order to use in cooking, according to their taste characteristics. Some dishes require a spicier onion, others softer and sweeter. In nature, there are many types of this culture, among them, in most cases, salad is chosen. This is the same onion, only with a sweet aftertaste. Its husk, like the pulp, can be of different colors:

  • white;
  • brown;
  • green;
  • blue.

The article will focus specifically on the blue form of a bow.

What is blue bow

For those who do not know what the purple bow is called, this article has been written. Each gardener calls the blue onion differently. Some say so - blue, others call it red onion or purple. All these names come precisely from the color of the bulb itself. Whatever it is called, its properties and characteristics do not change. This vegetable came to Russia from distant Spain and after long and fruitful efforts of breeders has firmly established itself in these parts.

At first, it was bitter, like an ordinary onion, but thanks to the work of professionals, the bitterness was partially gone, and the vegetable became beautiful in appearance and with a sweet taste. The bulb of this species has a rich purple color. Not only the surface, but also the pulp acquired the same shade. Naturally, all the bitterness did not come out of the product, it had a delicate, more pleasant aftertaste. Purple onion contains a large amount of useful trace elements, which is why it is widely used not only in cooking, but also in folk medicine.

All these varieties differ among themselves in shades, as well as in taste and useful properties. Lilac onions are very beneficial for the health of the human body.

White onion also belongs to the salad type, one of the varieties of which should be noted the Exibishen variety. This is a real giant. Exibish onion grows up to one kilogram. This is the weight of one bulb.

It is important to know! To grow varietal onions only on a feather, the seeds must be sown close to each other so that the bulb itself does not have the opportunity to grow. At this time, the feather, on the contrary, will stretch upward. When growing green onions, do not forget about cutting arrows.

Blue onions are not only well preserved, they are not afraid of pests when grown, and they practically do not get sick. Like all vegetables, this species has its own ripening dates: early, mid-season and late. But, nevertheless, all of them can be grown in Siberia.

Features of growing the species

Spring is the time to grow vegetables, one of which is onions. Salad onion differs from the classic onion and the way it is grown. Rarely a variety can be grown from a set. In most cases, this is seed propagation. Most lettuce onions last less than four months. In addition, it is divided into three types according to its taste. Namely:

  • acute;
  • peninsular;
  • sweet.

But it should be borne in mind that the taste of this vegetable depends on the place of cultivation and care of the plant. Salad onions can be distinguished from spicy ones by the consistency of their pulp. It is more juicy and dense. Most often, these varieties grow well in the southern regions, since they need a lot of heat and light. As you know, in the south, daylight hours lasts at least fourteen hours.

Growing blue onions

It is also recommended to grow salad onions from seeds because in this case it becomes more resistant against the attack of pests and diseases. Sevk is threatened by such diseases as:

  • downy mildew;
  • white rot;
  • various viruses;
  • nematode.

But, if you plant onions with sets, this has its positive qualities. The sevok sprouts much earlier than the seeds, respectively, the bulbs begin to form and grow earlier. Weeds growing nearby cause much less discomfort to the planting (but this does not mean that weeds should not be removed from the garden). Planting onions with sets is much easier than seed sowing.

When onions need to be planted in a small area, it is possible to grow seedlings. It is grown on a windowsill or in greenhouse conditions. It is best to start doing this two months before planting the crop in open ground. In the container where they intend to sow seeds, it is necessary to make drainage. For this, a hole is made in the bottom, into which excess water will flow. Small pebbles or expanded clay, pretreated for disinfection and warmed up, are poured under the soil layer. For a plant, take a mixture of peat with garden soil. It is leveled and seeds are placed on the surface. Then a thin ball of soil is poured, which does not exceed half a centimeter.

Planting onions in open ground

Then the dishes with the sown seeds must be covered with foil and placed on the windowsill. Periodically, the soil needs to be watered and fertilized. After the emergence of shoots, an impromptu greenhouse must be opened and the air temperature must be slightly reduced.When the seedlings are one month old, roots will begin to appear. At this time, the soil must be watered abundantly and fertilized every seven days. Thus, young seedlings will grow and develop normally.

When the seedlings become strong and take root well, they are hardened in the fresh air, and then planted in open ground. Thus, growing onions by seedlings is similar to planting with sets. The bulbs grow large and healthy. They become resistant to diseases and pests.

Storing blue onions

Winter is the time when the human body needs vitamins and minerals. An onion stock will help with this. Sweet varieties of onions for long-term storage require the creation of certain conditions. Long-term storage depends on three factors, namely:

  • dry dark room;
  • room air temperature;
  • humidity below sixty percent.

Onion storage

Sweet onions should be stored in a box, but without removing the husk, or, as in the old days, collected in a stocking. The air temperature in the room should not be lower than -3 and not higher than +10 degrees. Salad varieties tolerate a minimum drop in temperature to 0 degrees. If the vegetable is stored in a basement, then it must be ventilated, since an increase in humidity up to 80% promotes rotting. If there is a lot of onions, then the following container is suitable for storing it:

  • wooden boxes;
  • cardboard boxes;
  • vine baskets;
  • bags;
  • mesh.

In no case should you use plastic bags, since the onions in them begin to steam and rot. As a storage place, in addition to the basement, you can choose a pantry or mezzanine. Air access is important for this culture. If you correctly follow all the recommendations for storing this vegetable, then it will always be present on the table.

When buying onions on the market, you need to pay attention to the following factors:

  1. On feeling, the head must be firm and strong;
  2. The pulp is juicy and fleshy;
  3. The top of the turnip is dry.

All this testifies to the quality of the purchased product.
