Forcing onions into feathers in a greenhouse in winter: we take on a troublesome but profitable task

Owners of private plots are wondering whether it is profitable to grow onions as greens in winter? This question may arise from a person who has never cooked food on his own. Any housewife knows perfectly well that it is impossible to live without this greenery either in summer or in winter. Its cultivation is possible not only on the windowsill in the house, but also in a greenhouse. Especially when there is a desire to get some profit from it.

It is important to remember that growing such a crop in a greenhouse in winter is very profitable for several reasons:

  • it will be possible to achieve higher yields;
  • this makes it possible to use racks in several tiers;
  • this type of greenery will be available not only in winter, but also in other months;
  • This is a very profitable business that brings in a solid income.

It is also necessary to remember that onions grown for greens in winter in a greenhouse are those vitamins that are so lacking in the cold season. But due to their insufficient quantity, you can encounter colds.

Varieties

Which onions for greens in a greenhouse in winter are best to deal with? Not all varieties of this crop are suitable to be grown in this way. It may turn out that you do everything right, invest a lot of effort and money into this business, but the profit turns out to be insignificant. And all because the wrong variety was chosen, since it grows poorly in such conditions or bears fruit late.

It is important to know: Not only late or mid-late, but even medium varieties are completely unsuitable for this purpose.

It is better to grow onions in winter in a greenhouse, which produce greens very quickly:

  1. Slime onion – great for year-round cultivation;
  2. Onions – characterized by high yield;
  3. Trampoline onion - in any winter month it will give a good harvest;
  4. Leek, the feather of which is somewhat similar to garlic, but has its own taste;
  5. The Egyptian variety is distinguished by the fact that it easily tolerates even frost. It is better to plant onion no earlier than December. It is very profitable to grow the Chinese variety, as it is a perennial plant.

Cultivation and agricultural technology

There is a lot of controversy about how to grow onions for greens in open ground, but we will try to find the best option for growing greens.

First of all, once spring frosts have passed and a stable positive planting temperature has been established, it is necessary to feed with an infusion made from weeds (the weeds are simply soaked in warm water and left to infuse for several days) in the proportion of a glass of liquid to 10 liters of water. You can also fertilize with urea (instructions and all proportions are on the package).

When the onion “gets” 5-6 feathers, it is necessary to perform a second feeding: add a spoonful of potassium and phosphorus to a bucket of water, stir thoroughly and water if the weather is dry. If the soil is moist enough, fertilizers can be sprinkled between the rows and then loosened. If fertilizing is carried out through watering, then try to water under the plants without affecting the greenery itself. By the way, it is best to fertilize and water in the evening, when the heat has subsided, which will allow, even if liquid accidentally gets on the feather, not to spoil it or harm the plant itself.

For a good result, you need to ensure that the soil around the onions is moist, as well as regularly remove weeds from the garden beds and loosen the soil.

Greenhouse equipment

When planning to grow onions in a greenhouse in winter, you need to prepare everything correctly. It is important to equip the greenhouse so that it is not damaged by precipitation or sharp gusts of wind. For these purposes, a polycarbonate greenhouse is best suited. It can be placed even in a small area. And installing it is not very difficult.

In order for the soil to warm up well in winter, you need to worry about a reliable foundation.

Also, when equipping it, you must not forget about the following systems:

  • watering;
  • heating;
  • lighting.

It is important that the plants continue to grow both during the day and at night. In this case, such a crop will give a higher yield.

Most of the money will go to the greenhouse complex itself, but such expenses will be justified. If you want to save money, then you can assemble and install such a structure yourself. Also, if you don’t buy ready-made hydroponics, but manage to prepare it yourself, this will also help you save something. And you will need a lot of ready-made planting solution.

Room for growing onions

You can grow onions in the summer in a simple garden plot, in open ground. However, in winter this will be impossible and then greenhouses and other sheltered premises come to the rescue.

Greenhouse

Building an ordinary greenhouse is not difficult. Besides, you can do this yourself. You just need to assemble the structure from a wooden frame, cover it with thick plastic film - and your greenhouse is ready.

The greenhouse will not require additional lighting or heating - natural conditions will be sufficient.


Greenhouse under construction for growing onions in winter

In a special article we will tell you in detail how to build a greenhouse with your own hands.

Basement or garage

People often use a basement or garage as an alternative to greenhouses. Only here the situation is a little different and requires a different approach.

To begin with, such rooms need to be insulated using polyethylene foam or polystyrene foam. Then you should attach the shelving. You can buy them at the store or make them yourself from available materials.


Any area can be adapted for growing onions

Growing technologies

It doesn’t matter, we are talking about growing onions for harvest in a greenhouse in the winter for yourself or for sale, you want to have a ready-made harvest as quickly as possible. And the second important point is the presence of such greenery throughout the cold season. And in early spring, you want to saturate your body with vitamins. And you need to know how to quickly get this green harvest.

Seeds or bulbs

In any case, feathers as greenery can be obtained both from seeds planted in the soil and from bulbs. But the ripening period will be different. And this plays a significant role when it comes to making a profit. And I myself want to get ready-made greens as quickly as possible. So it turns out that it is more profitable to plant bulbs in prepared soil rather than seeds. The feather will grow out of them much faster. If the greenhouse is unheated, then it is better to plant nigella in it in early spring. But for this, the seeds must be properly prepared. Before planting, they need to be soaked.

In the sawdust

Many gardeners grow onions for greens on sawdust. Sawdust retains moisture well. But at the same time, they allow oxygen to pass through perfectly. This is achieved due to the porous structure of sawdust. But in order to disinfect them, in order to remove various bacteria and microorganisms, the sawdust must be treated with boiling water. The landing process consists of the following steps:

  1. preliminary soaking of the bulbs using a solution of potassium permanganate;
  2. sawdust is prepared and placed in containers;
  3. bulbs are laid out on top;
  4. then all this is covered with an additional portion of sawdust;
  5. after this you can start watering the sawdust with warm water;
  6. To make the feather appear faster, areas with planted bulbs are covered with film.

Hydroponics

Growing onions hydroponically seems more attractive, since there is no need for soil at all. The bulbs are simply placed in vessels with water, where nutrients are added. But this option is not very cost-effective, because it will require significant costs for a hydroponic installation. True, these costs are later compensated.

Why growing onions in a greenhouse is a good business idea

Do you doubt that your company is profitable?

Let me give you some indisputable evidence:

  1. Onions for seeds are sold at a price of 15-20 rubles per 1 kg, and the price of feathers in the off-season reaches 200 rubles. per kg.
  2. To open a business you do not need large start-up capital, and monthly expenses for purchasing seeds, heating and water are low.
  3. For sowing, a small plot of land or a summer cottage is sufficient.
  4. This plant is unpretentious. The production technology does not require significant labor and monetary costs.
  5. If you plant an early ripening variety, the first profit will be in a month and a half. Varieties such as batun and heirloom onion produce good greens in 3-4 weeks.
  6. Stable demand all year round.
  7. It is possible to grow feathers for sale in a greenhouse all year round, and the harvest can be harvested 7-9 times in a year.
  8. Sale fresh, dried and frozen.
  9. There are many distribution routes: vegetable markets, supermarkets, grocery stores, wholesale buyers, kebab shops, restaurants, cafes.

On my garden plot there is a small bed of spring onions.

It is perennial and requires virtually no maintenance. Tolerates southern winters well. After trimming it quickly produces new feathers. There is plenty of greenery from several bushes for our family. I am sure that greenhouse cultivation of onions and its well-established sales will bring a stable income.

The soil

Onions are not very picky about the type and composition of the soil. Therefore, almost any land can be used for planting it. But still, in order to increase productivity, several conditions regarding the soil must be met.

The soil should be:

  • wet;
  • loose;
  • with feeding.

How can you make black soil loose? You just need to add sand to it.

If we are talking about growing onions in a greenhouse in winter for beginners, then such preparation may be quite enough. But it is much more profitable to use not just soil, but to make special racks. And then boxes are installed on them, into which soil is already poured. It will definitely need fertilizing in the form of wood ash. This will help achieve a higher yield.

Gardener Ilya Bydyashkin in his video shows the arrangement of his greenhouse with racks for the profit of green onions.

Market and demand analysis

Green onions as a business are considered in mass production. This perishable product requires sale within 2 days. Before planting, it is recommended to establish a sales network for the grown crop. This will allow you to estimate the required production volumes and analyze competition in the local market.

On average, the monthly production volume will be 300-500 kg. There is demand for green onions all year round, but the cost is seasonal. In winter, the price of products will be 100 rubles, in summer – 60 rubles. Sales should be established through supermarkets, wholesale and retail markets.

Temperature

The temperature in the greenhouse is also important, as it should be ideal for growing such greens. For its germination you will need from +15 °C to +18 °C, and in some cases up to +20 °C. The temperature depends on the selected variety. But if we are talking about growth, then you can save a little on heating. Here you can keep the temperature to +10 °C, this will be quite enough. And given that it takes more time just for growth than for germination, a lot of money will not be spent on heating the greenhouse in the winter.

  • If the temperature in the greenhouse is high, reaching +25 °C, the grown feather will be tall, but thin, and bitterness will be felt in it. And because of their height and weight, they will begin to lie on the ground, so you won’t be able to get much profit for them.
  • If the temperature is lower, the leaves will stand straight and are distinguished by their strength.

Watch a video of gardeners from Krasnoyarsk who have been successfully growing onions in a greenhouse in winter for many years, even in the harsh conditions of Siberia.

Technology on how to grow a good harvest

In the sawdust


Inventory:

  • wood sawdust;
  • required amount of sets or bulbs;
  • container with drainage holes.

Preparation for landing:

  1. Sawdust is placed in a container and poured with boiling water.
  2. After cooling, the water is drained, soaked in a solution of saltpeter or charcoal is added. To prevent rot from forming, fertilizers are used that act as sorbents that absorb some of the moisture.

Onion preparation:

  1. Cut off a quarter of the top and make shallow, vertical cuts.
  2. Place in warm water for 12 hours, cut off the tops.
  3. We water the bulbs with water at a temperature of 30 ° C, then cover with a blanket and leave for 3-4 days.

Planting scheme and technology:

  1. deepen the bulbs well and place them close to each other;
  2. fill the space between the root vegetables with dry sawdust; there is no need to fill the vegetables themselves;
  3. in 2 weeks the harvest will be ready;
  4. The thickness of the sawdust layer in the container should be 2–3 cm.

Care:

  • Green onions planted in boxes are moistened immediately, then every 7 days.
  • Basically, the green plant is not fed. The only thing that can be added to water when watering is hydrogen peroxide (1 tbsp per 1 liter of water) for disinfection.

In greenhouses in winter


Inventory:

  • greenhouse with soil;
  • boxes;
  • peat;
  • humus;
  • fertilizers

Preparation for landing:

  1. Soak the bulbs in warm water for 12 hours, dry them, cut off the necks, cover with burlap and leave for 4 days.
  2. Mix the soil with peat and humus, add superphosphate and sodium chloride, and moisten.

Planting scheme and technology: it is necessary to plant onions in the ground using a bridge method, pressing the bulbs tightly against each other. Water once every 10 days.

Care:

  1. After planting, water with slightly warm water; an important issue is the development of the root system, so a temperature within 12 degrees is required for several days.
  2. Next, the temperature is raised to 20 degrees. The harvest will be in 3 weeks.

Hydroponics method

Inventory:

  • specialized equipment (plates);
  • liquid fertilizer.

Preparing the bulb for planting: cut off the top of the bulb and leave it in the shade for four days.

Now we need slabs and liquid fertilizer for hydroponics.

Landing:

  1. First of all, it is necessary to saturate the mats with fertilizer in order to plant the onions in a moist substrate from which the bulb can immediately receive nutrients.
  2. The bulbs are located close to each other. If you plant bulbs whose tops have already swollen and feather growth has almost begun, then they need more space. In this case, the distance between the rows should be about 2-3 centimeters and the same between the bulbs in the row.
  3. Sprinkle the top of the onion with a layer of about 1 centimeter of vermiculite.

Care:

  1. The onions must be kept in a cool and dark place for 10 days. This period is necessary for the root system of the bulbs to develop well. In the future, the intensity of feather growth will depend on it.
  2. After this period ends, the onion will need a lot of light and heat.

In the open ground


Inventory:

  • seeds;
  • territory;
  • fertilizers

Preparation:

  1. the seeds must be soaked for a day in warm water;
  2. drain the water, place in a weak solution of potassium permanganate, treat with anti-fungal preparations.

Attention!

It is better to sow in mid-summer; it is important that the soil is loosened and fertilized. You can mix the soil with:

You can mix the soil with:

  • humus;
  • urea;
  • potassium chloride;
  • superphosphate;
  • wood ash.

Planting: plant seeds in a loosened bed using a bridge method; by autumn the feather will be about 20 cm; for the winter it is important to mulch the bed. Growing green onions as a business is not a difficult task with minimal investment at the start, the key problem is marketing, it is necessary to immediately establish a sales and transportation system, because

the result is a perishable product, this point can be decisive in determining the profitability of the business, the amount of profit directly depends on the profitable sale of the grown crop

Growing green onions as a business is not a difficult task with minimal investment at the start; the key problem is marketing; it is necessary to immediately establish a sales and transportation system, because the result is a perishable product, it is this point that can become decisive in determining the profitability of the business; the amount of profit directly depends on the profitable sale of the grown crop.

Lighting

You definitely need to worry about the light in the greenhouse. In winter, daylight hours are short, so artificial lighting is indispensable. But you don't have to worry about this too much because these plants won't need light 24 hours a day. It is necessary to ensure that there is at least 12 hours of daylight. This means that artificial lighting will only be used for 6-7 hours. Particular attention should be paid 12-14 days after planting, when feathers begin to develop. Otherwise, development will slow down, the feather will not only be elongated, but will not gain the required green color and will turn out to be light green. To achieve good results, a large dose of light will be needed during the last week before harvest.

It is important to choose the right spectrum of lighting for growing onions in winter. It is best to choose fluorescent lamps with a blue spectrum. For this purpose, linear metal halide lamps are usually used.

However, among amateur gardeners, there is successful experience of growing onions in a greenhouse in winter without the use of artificial lighting. Denis Ulyanov, who has been forcing onions for several years, shares his experience:

Advantages and disadvantages of onion business

There are several subtleties that are present in any business, and this one is no exception.


Large greenhouse for growing onions

Pros of growing:

  1. Fast . Onion cultivation has a short production cycle. This way, in just a month, you can get your products and start selling them.
  2. Easily . Caring for onions is not difficult. On average, for a site of 10*10 meters, a person only needs 1 hour of free time. That is, one person can cover large areas in a day.
  3. Unqualified specialists . Planting onions, processing them, watering them and harvesting them does not require any special knowledge, so anyone with any education can work with it.
  4. Great performance . Depending on what technology you use, you can regulate the amount of future harvest. This means that you can install onion beds in several tiers, which will save space and increase productivity.
  5. Unpretentious culture . To grow onions, it only requires watering, lighting (about 15 hours a day) and the right temperature (about 15 degrees).
  6. Cheap . Investments as such are not required, only for the construction of a greenhouse. Plus, they pay for themselves quickly.
  7. Demand . As already mentioned, everyone always needs onions.


Onions are sold in huge quantities during the season.

Minuses:

  1. Conditions . It is not possible to produce onions yourself everywhere, since not all conditions are suitable for growing this crop. If you live in the northern region, additional costs will be required to conduct light and heat.
  2. Plant nutrition . Such fertilizers will require additional costs.
  3. Staff . If you do not plan to do this business yourself, you will have to hire staff, which will also cost you money.

Humidity

When you plan to grow onions in a greenhouse for greens, you need to think about ensuring optimal humidity of both the soil itself and the air in the greenhouse. Air humidity should be between 70 and 85%. But the onion variety also plays a big role here, so you need to know when to water the plants more and when less moisture is needed. The water for irrigation should be a little warm. If it turns out to be cold, the desired result will not be achieved, the plant will simply slow down its growth.

For the first 2 weeks you need to water at least twice a week. And in some cases, more often. And then you can water it only once a week.

When watering is carried out, we must not forget about the correct temperature regime. If it was from +15 to 18 °C, then when watering it needs to be raised to +18 or even 22 °C. This only needs to be done once a week, and then the temperature can be lowered again.

Revenue and sales

Finding a buyer before the growing season took me a lot of time, but it brought results.

I was able to negotiate with a wholesaler at the largest vegetable market in the city, which made the task of selling much easier than if the goods were transported to different retail outlets.

Georgian Tamara was ready to buy up to 300 kilograms of green feathers from me every 2 days, which even exceeded my offer.

Her most important requirement was to carry high-quality and fresh product of the required length. The first batch of 280 kilograms was purchased at a price of 230 rubles/kg, which brought in 64,400 rubles.

Then, over two months, 8,432 kilograms of the product were sold at prices ranging from 170 to 230 rubles (the price changed every day, but on average was 200 rubles/kg).

That is, every morning I was not sure of a good price, because Tamara could offer me 100 rubles/kg, and I would agree. The buyer always sets the price! This is exactly the case in the wholesale sale of vegetables for cash.

As a result, it turned out that for the sale of 8432 kilograms of feathers I earned 1,687,400 rubles. Let me make a reservation right away: I was lucky with the price and conditions I found myself in.

I personally know examples where people invested a lot of money in this type of business and went broke due to the low price of the product.

I was successful because I paid a lot of attention to finding sales. You can grow a great product, but if you don't find a buyer, you'll end up with banana boxes full of rotting onions.

My bet was on bulk at a good price and it worked.

You can earn up to 2 million rubles with greenhouses of my size. in a couple of months. To increase profits, onions could be packaged in bunches, which are actively purchased by stores and chains.

On their counters, a 100 gram bunch of onions costs 100 rubles, and such bunches are purchased for 300 rubles/kg (300% profit).

The cost of reformatting is small (film and a packaging machine with scales), but it takes much more time, so I did not use this option.

I also want to say that you can enter into agreements with restaurants and cafes. On average, they take 40 kg/week at a price of 250 rubles/kg. You will have to travel to all establishments in person and negotiate.

But if you have problems with selling, this option is very helpful.

If I decided to expand production, then for sales I would use all the options described above with an increase in planting area.

Planting and growing

When planting onions, you should consider its variety. In some cases, it is more preferable to cultivate by seed. But other varieties are planted by selecting seedlings. It is necessary to check that the soil is moist. But under no circumstances should overflow be allowed. In this case, the bulbs will begin to rot.

It is advisable to plant the bulbs in rows, this will make it easier to care for them. You can sit next to each other. It is better not to use pure black soil for growing this crop. It is much better if the soil is sandy. But it is advisable to fertilize it, if not with peat, then at least with ready-made humus. It is important to remember that this plant loves light and warmth, but elevated temperatures are dangerous for it.

Look what crops gardeners from northern Asia managed to grow in a greenhouse in winter.

How to grow onions in a greenhouse in winter - a detailed business plan

A business plan is your insurance against unnecessary expenses. It is necessary to analyze each stage of business development, calculate business profitability, and calculate start-up costs. Planning will help you weigh all the pros and cons of the project, find where and how to sell the products.

The business plan includes choosing a growing technology, installing a greenhouse and equipment, and searching for buyers. Let's consider each of the planning stages in more detail.

Stage 1. Construction of the greenhouse

To start, all you need is a small polycarbonate greenhouse that will fit on your garden plot. Make a foundation in it for greater structural strength and better soil heating, install an irrigation, heating and lighting system.

The purchase of equipment and installation of a greenhouse complex is the largest share of costs at the start. But without creating conditions for plants, you will not get high yields.

Don't have substantial start-up capital? Assemble the greenhouse yourself without hiring specialists. Instead of a sprinkler system, use a regular watering hose. Assemble the racks from scrap materials.

Rational use of solar heat will help you save on heating costs. Use drawings and diagrams from the Internet. Adapt the finished frame drawing to your site.

Stage 2. Selecting and purchasing seeds

Buy material for sowing (onion sets, seeds) only in specialized stores or in greenhouse complexes. Use planting sets and seeds to obtain stable harvests throughout the year.

Carefully inspect the seed. The bulbs must be strong, without rot and characteristic odor. Seeds are the same size, without white or grayish coating.

Stage 3. Soil preparation

Onions are not picky about soil. It is desirable that it be moist, loose, and contain additional food. Add sand to the soil for growing it to loosen it, as well as pre-prepared or purchased compost and wood ash. Pour the prepared soil into boxes on racks, level and moisten.

Don't know what to choose: sawdust or soil? Watch a video comparing the yield on sawdust and on soil:

Stage 4. Growing greens

The soil should be moist, but not overwatered. Excessive moisture will cause the bulbs to rot. The dry period will slow down the growing season. Onions love light and warmth, but cannot tolerate heat. Monitor the optimal temperature level in the room.

Stage 5. Sales of finished products

Properly organized sales of products is the key to a successful business. Sell ​​your grown crops at local vegetable markets. Visit supermarkets, catering establishments, offer your goods to wholesale buyers.

To sell greens at the market "from hand" you will not need documents for trading. To rent a retail outlet at the market, sell in supermarkets and grocery stores, you need to register with the state tax service.

Open an individual entrepreneur or peasant farm. OKVED code 12.1 - entrepreneurship in agriculture (growing beets, cucumbers, seedlings for sale and other types of agricultural business) and 12.2. - growing greens. Taxation is 6% according to the Unified Agricultural Tax.

Don't forget about advertising. A bright sign, promotion on social networks, on online trading platforms, stickers on cars - all this will make your production recognizable and your products popular.

Top dressing

When growing onions in a greenhouse in winter for sale, you must not forget about periodic feeding. For this purpose, nitrogen-mineral fertilizers are usually used. They must be combined with watering. That is, you need to add them once a week. It is best to use a mixture of ammonium nitrate. But it’s good if such fertilizing is combined with potassium chloride. Urea is also great.

To grow onions in winter in a greenhouse, it is better not to use organic fertilizer. That is, it is advisable to exclude any humus.

When fertilizing is applied, under no circumstances should drops of it be allowed to fall on the stems, as this will lead to the appearance of light spots.

Where to start an onion business?

When you have decided on the premises and have firmly decided to continue selling your own grown onions, you need to think about registering the business. It is clear that without it you will only be able to sell onions to your neighbors or friends, and even then it is illegal. Registering a business will make it possible to supply the product to markets, shops, restaurants, cafes and other establishments.

The first step is to decide what form of business you will run. There are two of them: LLC or individual entrepreneur, each of which has its own nuances. You can register your business yourself by contacting the tax office of your area. True, it will take a lot of time to prepare documents. But there is another way out - order registration through a law firm, which will do everything faster, although it will not be free.


The difference between individual entrepreneur and LLC

Documents for registration

As mentioned above, there are two forms of business. Each of them has its own characteristics and its own documents.

You can find out the exact list of documents required to register your business from the tax service or a law firm.

Required budget to start a business

Start-up investments for an onion growing business include purchases of:

  1. Lamps for additional lighting (if you are not growing in greenhouses or with insufficient light) – 5,000 rubles.
  2. Wires – 1,500 rubles.
  3. Shelving – 6,000 rubles.
  4. Baths for shelving – 12,000 rubles.
  5. Desktop – 3,000 rubles.
  6. Irrigation equipment – ​​3,000 rubles.

Thus, to start work you will need 30,500 rubles. However, this price is not final, because each region may have its own prices.


Onions in the greenhouse

Monthly costs:

  1. Purchase of soil – 3,000 rubles.
  2. Lighting – 700 rubles.
  3. Heating – 2,000 rubles.
  4. Watering – 1,500 rubles.

Total – 7,200 rubles per month for one harvest.

Profit

Start-up capital takes a bit of a toll when you don’t know what you’re getting into or what you’ll earn. If you already have a growing room at your disposal, you will need about 30,000 rubles.

In a small area (15-20 sq.m.) you can grow more than 50 kg in one harvest. Thus, in 4 harvests you will get more than 200 kg of onions. If you take 200 rubles for the cost of one kilogram of onions in winter, then for one harvest you will receive more than 10,000 rubles.

Onions are most in demand from October to April, when it is frosty outside. During this time you can earn more than 80,000 rubles. By extracting the amount of your starting capital from the income, you will receive about 50,000 rubles in net profit.

Harvesting

Whatever the winter turns out to be, cold or not, if you choose the right onion variety, you can get a harvest very quickly. If, according to forecasts, it will be very cold in winter, and the temperature in the greenhouse will drop to zero, then it is better to plant the Egyptian variety, it is not afraid of such changes. In any case, harvesting is already possible a month after planting.

Watch a video in which a gardener compares technologies for growing onions in a greenhouse in winter using pine sawdust and soil.

What varieties of onion vegetables are best to plant at home and in a greenhouse?

There are many varieties that are suitable for these purposes; today we’ll talk about the most common ones. To do this, let's create a small table:

VarietyQualities and advantages
OnionThe seeds are cheap when compared to other varieties. Most often it is chosen for planting before winter. If he lives with you for several years, then you can cut feathers about three times per season. Productivity is about 6 kg per 1 sq. m.
Multi-tiered bowThe most unpretentious variety, has great productivity, produces a lot of fruit. Doesn't freeze even in cold weather.
ChivesThe leaves have a specific tasty smell. Half a meter tall, quite tall. They don't get rougher over time. From 1 sq. m. you can collect about 3 kg.
ShallotShallots smell and taste like garlic. Family onions ripen quickly and grow at any time of the year. With proper care it produces a lot of fruit.
LeekGarlic tart taste. From 1 sq. m. you will collect about 2 kg of fruit.

How to grow onions in a greenhouse in spring?

Onion seeds are not often used for planting in winter in a greenhouse. Firstly, this option is more suitable for growing in large-scale production. Secondly, the initial costs will be too high. And thirdly, it will not be possible to get a harvest very soon; usually the feather will be ready for cutting no earlier than after 2 months. So it turns out that it won’t be possible to sell it profitably with small production.

It is best to plant seeds in a bud in early spring. To do this, select varieties that are able to reproduce non-vegetatively. The landing method here is as follows:

  1. soaking in potassium permanganate a week before planting;
  2. for good swelling the temperature should be +20…+25 °C;
  3. After swelling, the seeds are removed from the vessel with water to dry.

To dry, the seeds are distributed on fabric, and when sprouts appear, they can be planted in the soil. For this purpose, furrows are used, which are then covered with earth.

Varieties of green onions for growing in an apartment

In an apartment, greens are most often planted with sets and onions, but you can also get a large amount of feathers from seeds at low cost - you will need loose soil or substrate, a shallow container.
