Chalcedony onions: description, cultivation and reviews


Onions - an indispensable vegetable in the kitchen of every hostess. It is not only added to different dishes, eaten just like that with bread, but also used in the treatment of virtually all colds. Onions began to be used by people more than 5 thousand years ago. Homeland of the vegetable is considered Central Asia. Today, no kitchen in the world can do without this vitamin-rich product. And thanks to agronomists, more and more new varieties appear, suitable for cultivation in different conditions.

Chalcedony semi-sharp and durable onion

The value of onions in this class is in several properties. It has excellent maturity - when harvest time comes, good fruits make up at least 92% of the total planting. Chalcedony is resistant to mechanical damage, and can also be stored for a long time. In any case, the harvest will be abundant enough to a new one; it is said by everyone who grew this variety. The bulbs grow approximately the same, slightly oblong, larger than the average size. The most important thing to ensure that planted onions is good soil drainage. Another great quality of this variety is its precocity. The vegetative period of maturation at Chalcedony is only 90 days. Chalcedony onions are frost-resistant - its seeds can germinate even at a temperature of +3 degrees, which for a normal variety will be simply destructive.

Growing up

The traditional scheme of growing onions is as follows: germinated seeds, small onions, a full harvest. Everything took about two years. Chalcedony onion seeds germinate immediately into full-fledged fruits - this is an annual plant.


Experts recommend sprouting seedlings first, as well as with cucumbers and tomatoes, and only after that plant them in open ground. When transplanting it is necessary to make sure not to break the sprouts, and also not to damage the root system. It is best to initially sow the seeds in a plastic container, for example, from under a salad. It is necessary to sow densely, and after - be sure to cover with a film and follow when the first loops of seedlings appear. Of course, one should not forget about watering - the more abundant it is, the richer the onion will be (however, it is not worth pouring too - this can lead to seed rot).

Site preparation for sowing

Many gardeners believe that it does not matter when preparing the soil for sowing - in the fall or spring, just before sowing. However, a certain preparation requires onions Chalcedony. Growing and the results of labor in this case will depend on the soil directly. Therefore, its processing is to do in the autumn. The earth should be carefully dig, carefully removing the weeds from it. You can leave large pieces of earth without breaking them, then more air will flow into the soil. But in the spring when re-digging the soil should be loosened to the "down" state. The most important thing in processing is to maintain the capillarity and structure of the soil. Sow the seeds as early as possible.

Sowing seeds

Accurate sowing is what Chalcedony loves onions. Growing from seed is only the first stage, after which no less important follows: transplanting into open ground. By the way, in order for the seeds to sprout faster, they are pre-soaked in warm water and left for a day. This is followed by mandatory disinfection - a solution of potassium permanganate of medium saturation. After this, the seeds are washed again with clean water. It should be borne in mind that during early sowing there is a possibility of frostbite of the sprouts with the last frosts. Therefore, the seedlings are covered with a film. It is necessary to stock up on lowland peat, which performs a very important function. They are sprinkled with beds so that a crust does not form on them, and also peat is an excellent insulant. If the transplant was successful, then after 7-10 days it will be possible to observe the mature shoots.


It is recommended to thin out too thick places right away - for this, the plant is not just torn out of the ground, but otgrebatsya to the side and removed together with the roots - Chalcedon has a very strong and tenacious root system. Between plants must adhere to a distance of 6-8 centimeters.


After thinning the beds (and it is better to do this when the onion grows a little, and it can be used for salads), it will be necessary to look after the bulbs. After the first rains, under the warm sunshine, the beds will quickly be covered with weeds. Giving them to germinate and grow is absolutely impossible. Therefore, to be lazy in such a matter is completely inappropriate. Chalcedony onion variety likes watering in dry weather, and also grows better if it is periodically fed.


Top dressing can be made together with watering. It is necessary to start feeding the plant from the moment when the 3-5 phase of this leaflet begins, as well as in the period when the fruit itself begins to form. Top dressing is carried out by full mineral fertilizer with microelements in liquid form. On exhausted soils, humus can be applied in the calculation of 7 kilograms per square meter. After spring tillage, minerals - potassium and phosphorus - are required to be applied, which must be distributed at 20 grams per square meter.

What is different about onions grown from seeds?

Chalcedony onions grown from seeds, different from bulbs grown from sevka. Initially, the difference is that you do not have to spend time on the germination of the seed plant itself, as well as on its preservation until the planting season. Onions, which are grown directly from seedlings, do not go to the arrow, but retain their qualities until the new harvest season begins.


By comparison: many varieties of onion during storage begin to deteriorate from the middle of winter, until the spring season remains at best half of the harvest. The rest of the onion is rotting and rotting. Also, chalcedony grown from seedlings becomes a real giant - the bulbs weigh up to 120 grams on average, and from one standard bed you can collect up to 5 kilograms of this golden miracle, incidentally, cultivated by Moldovan vegetable growers.

Features agrotehnika

Yet there are several factors that will need attention. From this will directly depend on the amount of the crop, but, of course, its quality.


The site on which Chalcedony onions will land should be located in a sunny place - the bulbs will quickly fill with juice, especially with good watering. Also in the garden should always be light loam or sandy soil of high fertility. If the soil is determined by acidity, then it must be slightly alkaline. Try to regularly fertilize the soil with such proven folk methods as ash, dolomite flour and lime lime. In the autumn, it is desirable to generously cover the earth with rotting manure - in its qualities it will be the best feeding. And yet - the soil in which Chalcedony will land should be four years of rest from the last planting of onions. Ideal for the preparation of the soil will be peas and pumpkin planted under the bow on the eve.

What you need to know more?

There is a list of certain diseases that Chalcedony is subject to. You will find their description below. The list looks like this: onion moth and fly, stem nematode, cervical rot, peronosporosis. Butterfly moths are not as dangerous as the larvae - they devour the plant. It is necessary to destroy the mole at the caterpillar age, and after that not to plant a bow in this place for at least a year. The fly strikes the plant so that it fades and dies. You can get rid of it with a solution of tobacco and soap. Nematode kills the entire crop at once. For the prevention of the land is treated with a solution of salt - 2 tablespoons per 10 liters of water. The rot affects the plant, forming gray spots.


From it will help chalk or charcoal powder. Perinosporosis kills the crop to the end. After infecting plants, plant onions on this site for at least 4 years. Top dressing and watering stop 20 days before harvesting (so that the bulbs do not rot later). The collected onions are left in the furrow, and then transferred to the room for complete drying.


So, what is good chalcedony onions? Reviews of vegetable growers boil down to one thing: it is tasty, long-stored, non-capricious, cold-resistant and prolific.
