How to grow large onions: what to feed. How to grow large onions on your own plot? Fertilizing onion sets in spring

Kira Stoletova

“Onions are good both in battle and in cabbage soup” - what kind of dishes are made from it! It is also used in cosmetology, in the fight against household pests such as cockroaches and ants. And its juice also helps if you don’t have enough tears to beg your spouse for a fur coat. The trouble is that the vegetable is not as unpretentious as it seems: it needs good soil, quality care and nutritious fertilizers for onions to grow. Without fertilizing, the bulbs will grow small.

How to grow a good harvest

Even the most fertile soil, rich in useful elements, is depleted over time, and for the growth and development of onions (and any other) onions, you first need good soil. To solve this problem, you need to add onion fertilizer to the garden bed. The catch is that without knowledge and experience it is easy to inadvertently harm plants: excess bait, as well as its incorrect use, can destroy an innocent vegetable.

However, properly used fertilizers will allow onions to grow larger and strengthen their immunity against diseases and pests. Growing, in addition to fertilizers for onions, includes other requirements. It is useful to know what is the best way to fertilize onions, however, even if other factors in caring for vegetables are violated, it will not be possible to grow them.

  1. It is better to arrange the garden bed on a loose piece of land, preferably in a well-lit area. The sun is an important element when growing almost all garden crops, including various types of onions. Soil composition is vital. The culture does not like acidic soils: it develops poorly on them and easily gets sick.
  2. Moderate watering is a necessary procedure, especially when the feathers grow, but in June-July it is time to reduce watering, and when the time approaches for harvesting, abundant soil moisture is no longer so useful. Overwatering leads to delayed ripening and, in the worst case, to root rot. High humidity leads to a reduction in onion storage time. For the same reason, plants should not be planted in areas where groundwater lies close to the surface: in such places the soil is too wet.
  3. Like many other crops, onions refuse to grow next to weeds. It is necessary to weed the garden bed regularly.
  4. You cannot grow a vegetable on the same piece of land every year - there is a good reason why this should not be done. Firstly, the earth is depleted of those substances that are needed for plant growth. The second reason is the diseases that the onions that grew here last season left their followers. It is better to choose places where potatoes or cabbage used to grow, but in no case where carrots or garlic were grown.
  5. Before planting the set, it needs to be prepared. Unlike seedlings and seeds, seedlings are more unpretentious.
  6. Growing is possible in different ways and for different purposes: this determines how to fertilize onions. For example, fertilizer for onions for turnips differs from feeding a plant grown for its greens.

Preparing for landing

Since fertilizing is so important, how to fertilize onions when planting? You need mineral fertilizers, and you also need to feed the plants with organic substances. You need to fertilize at least 3 times. In order for the crop to grow better, it is worth preparing the soil long before planting, in the fall. How to do it?

  1. Since vegetables do not like acidic soil, lime should be added in the fall.
  2. Manure mixed with peat and a small amount of ash is applied to the ground. Another option if desired: complex potassium-phosphorus fertilizer.

In the spring, they continue to prepare the land before planting: they dig up the bed, loosen it and get rid of weeds. If you didn’t have time or forgot to prepare the soil in the fall, in the spring you add superphosphate, compost, and “feed” the soil with chicken droppings.

Variety of fertilizers

Groundbaits are saturated with various useful minerals, but what kind of fertilizers are needed for onions?

  1. Organic fertilizers saturate the soil and facilitate the absorption of other types of fertilizers.
  2. Fertilizers rich in nitrogen are needed for onions so that their feathers grow more actively. The lack of this substance entails weakening of plants, delays in development, which ultimately affects the richness of the harvest. Nitrogen fertilizers are primarily represented by chicken manure. Urea is also suitable, and you can also feed the soil with saltpeter;
  3. Potassium strengthens the plant, allowing it to withstand the test of drought with flying colors. Ash and some mineral additives contain potassium; summer residents often use potassium salt;
  4. Superphosphate is a complex fertilizer that includes various substances, including phosphate, which is necessary for the growth and development of onions. Superphosphate is an excellent fertilizer for onions, which improves the plant's immunity.
  5. Fertilizing is most conveniently done with purchased complex mixtures. Such fertilizers for the growth of onions have a balanced composition. For example, Agricola-2 fertilizers for onions and garlic or Reflex are good.
  6. You can feed future products with yeast: this is an excellent tool for preparing the soil for planting. Summer residents do not use undiluted yeast: they are first diluted in warm water.

Feeding scheme

It’s not enough to know what to fertilize onions with; you also need to know how to do it. It is recommended to apply fertilizer in the evening. Dry mineral fertilizers for onions are either sprinkled on the ground shortly before the rain, or diluted with water and carefully begin to apply the resulting solution under the root. The main thing is not to accidentally water the pen. Complex fertilizing is applied according to the same principles.

Organic and mineral fertilizers for onions are applied at 3 stages of plant growth. At different stages you should feed with different substances. We must not forget to fertilize onions in the spring, before planting, and even better, in the fall. Below are the rules for feeding and fertilizing onions:

  1. They begin feeding for the first time 14 days after planting. The feather should grow up to 9 cm long. During this period, nitrogen fertilizers are applied. Urea is especially good in this role, as it is safe for young vegetation and is quickly absorbed. Urea is also useful for other plants in the garden.
  2. The second time the fertilizer is applied 2-3 weeks after the first. It is necessary to feed it mainly with phosphorus and potassium. You can add a little nitrogen. For this stage, summer residents buy “Agricola No. 2”. After 7 days, for preventive purposes, it is better to spray. You can make the product yourself: a little copper sulfate on a spoon of soap and a bucket of water.
  3. They begin to feed the third time when the onion forms a head. This time they use drugs with large amounts of phosphorus and potassium.

What fertilizers are needed for onions are decided individually after a visual assessment of the condition of the plant. If the appearance of the onion leaves much to be desired, the feather grows poorly, which means there is too little nitrogen in the soil, you need to add it. Urea is suitable for this, but you cannot water the beds often with such a solution. Are the onions no longer green, but yellow? This means that the problem is a lack of potassium, which it is advisable to compensate for as soon as possible. Greens lose color and die in vegetables that lack phosphorus.

These signs may indicate diseases and pests; in any case, you should be wary. Good growth and a bountiful harvest are only possible if there is a balance of nutrients. An excess of them is just as harmful as a deficiency. Nitrogen promotes green growth. If there is too much nitrogen, the vegetables will grow nice and lush greens, but they will not have the energy to form large bulbs.

You can do without 1 feeding if it is clear that the plant is feeling great, greens grow well on it and the green onions themselves are not pale. The third fertilizing is also not always necessary; it is carried out only when the soil lacks nutrients.

Caring for different types

Onions are the most famous type; their heads are used in cooking and folk medicine. However, the extensive family also includes other types of useful plants: shallots, leeks, and ornamental varieties. Growing onions for feathers occurs differently than for turnips.

When they say “for the feather”, it is assumed that vegetables are grown for greens, and not for the head. Green onions contain many beneficial substances. In the spring, when the human body’s immunity is too weak, the vegetable becomes a real salvation. Fertilizing onions for turnips should be balanced, and the amount of nitrogen in the fertilizer should be gradually reduced. In order for only greens to grow, on the contrary, you need more nitrogenous fertilizers.

Ammonium nitrate is fed in the first stage. For subsequent ones, other elements are added in small quantities, for example, good wood ash.

  1. Leek. Leeks are not like their fellows, but this does not mean that they do not need abundant feeding of onions with organic fertilizers, alternating with mineral fertilizers. The first is done 2-3 weeks after planting with ammonium nitrate and potassium salt. When the time comes for hilling, wood ash will be used.
  2. Shallot. The first time you need to fertilize shallots is when three leaves grow. To do this, first prepare an infusion of weeds, add potassium and carbamine to 10 liters of water. Urea is suitable as an alternative to carbamine. The second time, the shallots are endowed with potassium and phosphorus.
  3. Decorative bow. They grow it for its beauty. Cultivation and fertilization for beautiful onions must be correct, only then the plant will become truly beautiful. The “flower” needs a lot of nitrogen, phosphorus and potassium, so it is generously fed with ammonium nitrate, superphosphate and potassium. Some summer residents apply the mentioned fertilizing and fertilizers for wintering onions in early spring. You cannot make a hole with decorative onions next to the bed where its edible counterparts grow, otherwise they will get to know each other too “closely” and as a result, a useless hybrid will grow.

Growing at home

Fresh green onions grown on a windowsill are much better than store-bought ones, despite the fact that the sets require no more care than flowers. It is enough to select the seedlings, prepare them for planting, and plant them in a container with soil or substrate. Vegetables take twenty-one days to grow. For home, you can take not even a set, but the most ordinary onion.

There are several ways to grow a “home” vegetable garden:

  1. Growing on water. To do this, you need to lower the roots a little into the water and wait. The water should be changed once a day, after the roots have strengthened - once a week. Minus: there will be few useful vitamins in such a vegetable. The deficiency can be eliminated by using fertilizers for onions during such planting. You need to buy liquid fertilizers for hydroponics.
  2. Flower pots on the windowsill. If you feel sorry for the pots, it is permissible to take a cut piece of a plastic bottle, arrange pebble drainage in it and pour soil on top. Organic fertilizers should be used, but their dose must be measured.

10 secrets of productive onions / How to grow healthy large onions

SUPER FEEDING AGAINST YELLOWING OF ONION LEAVES AND FROM PESTS!

The success of growing garden crops depends on fertilizer; you cannot neglect it, so the seedlings can turn into a large onion or delight you with a rich, juicy feather.

Onions grow in almost any soil, but it is best in open, ventilated and illuminated areas. The crop is grown for the head and feather. The best predecessors for onions are potatoes, tomatoes, beans, pumpkin, zucchini, cucumbers, peas, and cabbage. Sets will not produce a good harvest on a plot without rehabilitation for 3-4 years. It is especially good to plant the vegetable next to carrots, which ward off onion flies.

Choosing the right site does not provide a 100% guarantee of a rich harvest. Onions are considered an unpretentious crop, but it is possible to obtain high-quality, tasty feathers and large heads only if properly selected minerals and organic matter are added before and after planting the sets. Nutrient deficiency does not allow the bulbs to gain green mass and grow.

The lack of organic matter and minerals can be compensated by changing the qualitative composition of the soil through appropriate complexes.

Soil preparation is an important stage in growing onions for turnips and feathers.

Vegetables need neutral, loose, nutritious soil, but an excess of micro- and macroelements, as well as a deficiency, negatively affects the crop. In order not to harm the plantings, fertilizing is carried out twice - in the fall and immediately after sowing. This is a prerequisite for obtaining large heads and juicy green shoots. It is not recommended to place beds in lowlands, where with the onset of warm months water stagnates for a long time.

Did you know that crying while chopping onions is very beneficial?! Thanks to the tears caused by the pungent odor of the vegetable, the mucous membrane is irritated, and the eye canals, which are prone to blockage, are cleared. This has a positive effect on visual acuity.

Measures to prepare the soil for planting onions in the spring

Includes several stages:


It is necessary to dig up and enrich the soil with organic matter in the fall, and not before planting onions. Introducing compost with seeding may introduce weeds. It is not necessary to change the acidity and add mineral complexes if the soil is neutral and fertile.

How to feed onions in the spring for turnips?

The soil prepared in the fall is considered completely suitable for growing. It does not require the introduction of additional compounds. This is true only for highly fertile lands. Most areas need spring enrichment with useful substances, which is carried out in two phases.

First feeding

It is carried out when the feathers reach a height of 10 cm and is carried out using the following compositions:

How to improve productivity?

We are constantly receiving letters in which amateur gardeners are worried that due to the cold summer this year there will be a poor harvest of potatoes, tomatoes, cucumbers, and other vegetables. Last year we published TIPS on this matter. But unfortunately, many did not listen, but some still applied. Here is a report from our reader, we would like to recommend plant growth biostimulants that will help increase the yield by up to 50-70%.

These preparations are considered the best for enriching the soil during the feather growth stage.

The second phase of feeding onions

It occurs at the beginning of the second month after the first. In order for the heads to grow large and tasty, they need potassium and phosphorus. Superphosphate and sulfate are placed on a bucket of water. Take 20-25 g of each component. This amount is enough for 1-1.5 square meters. m. beds.

The virtual absence of green mass growth requires intervention. It is recommended to water the plantings with a liquid mixture of a glass of mullein diluted in a liter of urea. The garden bed should be fertilized with the preparation twice every 14 days.

How to properly feed onions?

Growing crops exclusively for greens has its own characteristics. The difference is that when planting a feather on a turnip, the green mass must be preserved so that the bulb develops well. Otherwise, the head will be small, and the harvest will significantly lose weight.

Onions are always planted separately, and fertilizing after planting the sets is chosen in such a way that it allows for high yields of the green part. Nitrogen is considered especially beneficial. A deficiency of the element has a dramatic effect on the appearance of feathers. At first they turn pale, then turn yellow, and growth is inhibited.

Soil enrichment scheme

In order not to lose the harvest, plantings are fed as follows:

  1. At the stage of the first green leaves appearing, the soil is enriched with ammonium nitrate or urea, which contain a lot of nitrogen. Take 30 g of the substance per bucket of water. The drugs are used separately, but not together. 10 liters per square meter is enough.
  2. A week later, potassium and phosphorus are introduced. They take either organics or chemistry. In the first case, wood ash is used, and in the second, a mixture of superphosphate (30 g) with potassium chloride (10 g) per 10 liters of water.

The simultaneous administration of nitrogen, potassium, and phosphorus complexes is permissible. They are introduced 2 weeks after planting the seedlings. The use of such a preparation involves only one enrichment of the soil, since it replenishes the entire necessary supply of nutrients for the full growth of feathers.

Organics or chemistry?

The choice of fertilizer for onions is the most important step for obtaining a rich harvest of turnips or feathers. Fertile soil produces good greens and juicy large bulbs, but you should also not overuse fertilizing. The crop is prone to the accumulation of nitrates, harmful to humans.

To avoid turning a healthy vegetable into an unsafe product, many farmers prefer organics. It produces a large amount of mineral elements, but not the maximum possible amount of yield. Therefore, when choosing what fertilizers to use in the spring, it is best to combine organic matter with chemistry, but feed the soil no more than 2-3 times per season.

Did you know that drugs such as “Allylglycer” and “Allylchep” are obtained from onions. They have an antimicrobial effect and improve intestinal motility. Medicines are taken for indigestion and atherosclerosis. They are prescribed to those suffering from the sclerotic form of hypertension.

Features of growing winter onions

Vegetable crops planted in the fall allow you to get a good and rich harvest. The vegetable is primarily planted to produce feathers, but when favorable conditions are created, it can also be planted for turnips. Particularly popular are the cold-resistant varieties “Ella”, “Shakespeare”, “Radar”, which can withstand down to -150C in the absence of precipitation.

Winter onions, if you choose the right fertilizer with the onset of spring, bring a much earlier harvest than when planted in the warm season, and have other advantages:

  • abundantly fruiting varieties produce up to four kilograms of vegetables per 1 square meter;
  • feathers suitable for food are released with the first thaw, when the snow melts;
  • resistance to the most common pest - the onion fly due to the wintering period;
  • good adaptability to adverse weather conditions in cold, warm, hot seasons.

The threshold of negative temperatures under snow cover is much higher than without precipitation. This makes the crop invulnerable to frost with extremely low temperatures, but in the presence of precipitation.

Chemical fertilizing of cold-resistant varieties

Wintering varieties of crops begin to fertilize with the appearance of feathers. Further growth of green mass and the diameter of the heads requires a sufficient amount of minerals, which are introduced into the soil according to the following scheme:

  1. After releasing the feather, the soil is enriched with a special ready-made mineral complex or a preparation of potassium chloride, superphosphate, urea, taken in proportions 1: 3: 2. For each square meter, 4-5 mg is enough.
  2. After 14-21 days, microelements such as nitrophoska are introduced. If you use this substance, add 1 tablespoon to 5 liters of water. This amount is enough for 1 sq. m.
  3. Bulbs that have reached a diameter of 3 cm need phosphorus. Otherwise, growth will slow down sharply. This can be avoided by adding superphosphate to the soil. The solution consumption per square meter is 10 liters, in which 2 tablespoons of the drug are diluted.

Some gardeners prepare their own compositions, others purchase mineral complexes in specialized stores. The choice depends entirely on the farmer.

Organics for winter crops

It is not necessary to resort to chemicals; it is quite possible to limit yourself to the use of organic matter. Pure fertilizing, similar to mineral fertilizing, is applied in three stages:

  1. With the appearance of the first arrows, slurry is used, obtained by dissolving a glass of raw material in a bucket of water.
  2. In the third or fourth week, the beds are watered with an infusion of 5 kg of any pre-crushed weed in a bucket of water, soaked for several days. It is highly concentrated and diluted with water 1:10 before use.
  3. The heads of sets that have grown to 3-3.5 cm are watered with a solution of wood ash. Place 250 g on a bucket, leave for several days, and dilute it in the same way as a herbal infusion.

Gardeners who know what and how to feed winter onions in the spring always reap a good harvest. Some prefer organics, others choose mineral complexes. The main thing is to use drugs according to a three-phase scheme.

That is why we decided to publish an exclusive interview with Oleg Gazmanov, in which he revealed the secrets of getting rid of joint pain, arthritis and arthrosis.

Attention, TODAY only!

Fertilizers for onions are applied at a certain time. To get a good harvest, you need to know when and what is best to use. Natural ingredients and inorganic mixtures are suitable for feeding. Complex fertilizers have a good effect on the growth and development of this crop.

The soil for planting onions should be rich in nutrients. This vegetable loves loose, weed-free, non-acidic soil and good light. Various types of fertilizing allow onions to fully develop and resist various diseases.

Like any other plant, onions need nitrogen, phosphorus,... Feeding is carried out 2-3 times per season. Both components of organic and mineral origin are suitable for these purposes. It is better to start preparing the soil for future planting of vegetables in the fall.

For the beds, select soils on which pumpkin, nightshade, legumes and cabbage crops grew that year. The land for planting onions is enriched with organic matter or mineral fertilizer. It is good to add manure or compost to the soil in the fall. You can mix these organic additives with peat. It will be useful to add a little ash to the ground. If the soil is acidic, neutralize it with lime. Since a neutral environment is better for onions. You can also use mineral potassium-phosphorus mixtures for autumn feeding. About 30 grams of such fertilizer per square meter of land is enough.

In the spring, the soil is dug up, treated to remove weeds, and loosened. It is better to make the beds high. If fertilizers were not applied in the fall, then it would be good to add organic matter and. Natural ingredients include rotted manure, bird droppings or compost. You can replace them with ammonium nitrate or.

Organic and inorganic fertilizers

Fertilizers of natural and synthetic origin, as well as their combinations, are suitable. Organic ones supply the soil with nutrients and improve its structure. As a result, water and air exchange processes occur more deeply. Natural fertilizers promote better absorption of inorganic types of fertilizers.

Fertilizers rich in nitrogen include manure, bird droppings, urea, ammonium nitrate and others. The component they contain affects the growth of onions and their full development. When feeding is applied, the feather begins to develop intensively. A lack of nitrogen will inhibit the growth of vegetable crops. As a result, the plant will be weaker and the yield will be low.

Superphosphate will enrich the soil with phosphorus. As well as other useful elements: potassium, calcium, magnesium and other substances necessary for the full development of the bulb. Thanks to this complex, it becomes more resistant to diseases. The components of the mixture activate metabolism, stimulate its growth, and increase productivity. Superphosphate can be produced in various forms.

Potassium is necessary to ensure metabolic processes. It ensures the plant's resistance to drought and temperature changes. This element is found in ash, as well as in mineral fertilizers such as calcium chloride, potassium salt,. Onions that receive a sufficient amount of potassium are stored better.

It is better to feed the vegetable in the evening. Mineral fertilizer for onions can be applied in dry form. It is scattered evenly over the garden bed and then watered. It is good to fertilize in this way after rain. But it is best to prepare an aqueous solution. It is poured at the root of the plant, being careful not to touch the feather. The next day, it is advisable to water the beds with plain water.

Feeding onions at various stages of development

Onions are fertilized at different stages of plant growth. From the moment the greenery appears until the turnip is fully formed, the vegetable requires various nutrients. Organic, mineral or mixed fertilizers are applied to vegetable crops. Fertilizers should contain those components that are most needed by the plant at a certain point in its development.

The earth is enriched with useful substances according to the following scheme:

  1. The first feeding of onions is carried out approximately 2 weeks after planting. At this time, sprouts need nitrogen for rapid development. If it is deficient, the feather will grow slowly, which may affect the yield.
  2. The second feeding is necessary 3-4 weeks after the first. Onions still require nitrogen-containing additives, but in smaller quantities. At this time, the vegetable needs phosphorus and potassium.
  3. You can feed the onion a third time at the initial stage of head formation. Potassium-phosphorus mixtures with a high content of main components are suitable for this.

During the first and second feeding, it is important not to overdo it. Otherwise, the bulb will use up its reserves to form greenery, and the development of the head will be less active. The last feeding of onions is optional. It will be required for soils with a low content of nutrients.

Vegetable crops can also be fertilized with special complex mixtures based on organic matter. Such fertilizers for onions are very useful, they have a balanced composition necessary for full development and growth. There are mixtures for special purposes, for example, Agricola-2 for onions and garlic. You can use fertilizers suitable for different types of vegetables: Giant, Effecton-O, Agricola Vegeta and others.

What is the best way to fertilize onions?

Many gardeners grow onions for greens. She's very helpful. It contains vitamins, microelements, and other active substances. Onion feathers are used mainly fresh, as they are not stored for a long time. In spring and early summer, the greens of this vegetable will be an excellent source of vitamin C. The amount of useful substances in feathers exceeds their content in the bulb itself.

When growing onions for turnips, it is better not to pick green shoots. Then the bulb will develop better. Therefore separately. In this case, we are interested in the yield of the green part of the plant, so the soil must be enriched with nitrogen. The lack of nutrients affects the appearance of greens. If there is little nitrogen, the feathers grow slowly, become pale in color, and then begin to turn yellow.

The first feeding of greens grown is necessary at the stage of the appearance of the first leaves. For feeding, you can use urea or ammonium nitrate, as they are rich in nitrogen. Approximately 30 grams per 1 square meter of soil is required. After 7 days, phosphorus and potassium components are added. You can take 30 grams of superphosphate, 10 grams of potassium chloride per 10 liters of ordinary water. An infusion of wood ash is suitable for fertilizing the soil. Some gardeners feed onions once, about 14 days after planting. At the same time, nitrogen, potassium and phosphorus fertilizers are applied.

Onions are an unpretentious garden crop. However, it is very sensitive to fertilization. The impact is immediately noticeable. With a sufficient level of nutrients, the vegetable develops more intensively. The onion turnip becomes larger and juicier. The feather is powerful and bright green. The crop ripens faster and is stored better.

Excess mineral fertilizers can accumulate in the plant. This has a bad effect on the storage ability of the vegetable. In addition, accumulated nitrates are harmful. Therefore, you should not overdo it with fertilizing. It is enough to apply 2-3 times per season. Organic fertilizers are undoubtedly good, but they cannot always provide the plant with all the necessary microelements. The combination of natural components with inorganic substances for fertilizing allows you to get the richest harvest.

Onions are undemanding to soil and not the most demanding crop. Anyone can grow it, but to get a rich and large harvest you will have to make an effort and show knowledge of agricultural technology, i.e. feed him.

Let's figure out how to choose seedlings and how to fertilize the plant so that the bulbs are large.

How to choose sets for planting: varieties

The best choice for growing seedlings so that they grow into large bulbs is a seed with a diameter of 1.4-2.1 cm. The rule “the larger the planting material, the larger the harvest” does not work here. Large bulbs will immediately begin to bolt, but small ones will have to grow up first to appear green.

The size of the root crop directly depends on the type of planting material. It also determines the timing of bulb ripening, fertilizing and harvest quality. The most popular varieties for obtaining large “turnips” are:

  • – the bulbs gain up to 150 grams of weight, ripen early, are well stored and are practically resistant to disease. The taste of the variety is not sharp, pleasant;

Another argument in favor of later planting of onions is the first peak of onion fly activity during the cherry blossom period. To prevent insects from attacking your seedlings, wait at least a week after the trees have finished flowering.

Responsiveness of onions to fertilizers

Onions practically deplete the soil of nutrients. It is extremely responsive to fertilizers, especially “to taste” mineral supplements. Root vegetables absorb nitrogen best - up to 100%. The second favorite nutrient for growing bulbs is potassium. It is consumed by 40-45%. In third place is phosphorus - the substance is absorbed by root crops by 25-30%.

How to feed correctly

A thoughtful approach to growing large onions involves fertilizing the beds in the fall. Organic matter is added to the soil: compost or humus. The optimal amount is 10 kg per “square”. If onions or other plants that devastate the soil used to grow in the same area, it makes sense to use mineral fertilizers.

Read about fertilizers for cucumbers.

In spring and summer, onion fertilization takes place in 3 stages. It is necessary to take into account that this feeding scheme is conditional, and focus more on the appearance of the plant:

  • good greenery indicates a sufficient amount of essential substances in the soil. In this case, it makes sense not to pick off the feathers and, in the second or third period of the growing season, use phosphorus-potassium supplements to form a large onion;
  • if there is no greenery or it is weak, the plant needs nitrogen;
  • yellowing feathers warn about low potassium content in the soil;
  • dry green tips They talk about the need to fertilize the plant with phosphorus.

onions prefer fertilizers in the form of solutions. An exception can be made only during the rainy season - then fertilizer granules are simply buried 5-10 centimeters into the soil.

First

Onion feeding begins when the first leaf forms and grows 10-15 centimeters. If it is bright green and juicy, you can skip the fertilizer. Otherwise, nitrogen is added to the soil at this stage of the growing season. It has a good effect on the formation of greenery. They try not to overdo it with the substance; nitrogen slows down the ripening of the “turnip” and reduces the yield. For 1-2 square meters of bed, 10 grams of the substance is required, diluted in 10 liters of water.

Second

The second stage of fertilization begins approximately 15 days after the first or 30 after planting. Potassium and phosphorus are used as the basis of the additive. The first is used to form bulbs. Phosphorus has a positive effect on the ripening and growth of large, dense “turnips”.

For the second feeding, the substances are diluted according to the scheme: 60 grams of superphosphate, 30 grams of nitrate and 30 grams of sodium chloride per 10 liters. The fertilizer is also enough for root watering of approximately 2 “squares” of land.

At the second stage of fertilizer, superphosphate is added

Do not pick the greens so that all the nutrients go towards the formation of a large onion.

When the “turnip” is formed, it is also useful to fertilize with calcium. It will reduce the acidity of the soil and promote the growth of good bulbs.

Third

The third stage of fertilization begins if the “turnip” has reached the size of a walnut and has stopped growing. Further development of the root crop is stimulated using the same granulated superphosphate - 40 grams of the substance per 10 liters of water.

Fertilizers for sprouting onions

Mineral, organic, and mixed fertilizers are suitable for feeding onions during the formation of large bulbs.

Do not “overfeed” the bulbs, they can accumulate nitrates.

How to Apply Organics for Planting

Organic fertilizers are less aggressive towards the plant; they saturate the soil with useful components and improve air and moisture exchange.

Manure, bird droppings and urea are rich in nitrogen, so they should be used in the fall. In spring and summer, they will attract pests, provoke the growth of feathers and contribute to the formation of small “turnips” of irregular shapes. Onions grown on organic matter will be sick, will not store well and will rot relatively quickly. How to plant onions in winter in autumn is described.

If your plants do not have enough nitrogen, dilute organic matter according to the following schemes:

  • Add 1 part horse manure to 20 parts water.. Then the resulting mixture is diluted again with water in a ratio of 1:10;
  • Dilute 1 kg of cow manure in 10 liters of water and leave for 7 days. The solution is also diluted with water in a ratio of 1:5.

The rows between the bulbs are watered with this and the previous additive. It is better for them to take rotted manure - it is less vigorous.

For predominantly sandy soil, it is advisable to reduce the solution concentrations by about a fifth.

At the second stage of the growing season, fertilizers for the formation of large “turnips” are prepared on the basis of grass. The greens are poured with water, pressed with a press and left for 3 days. For 5 liters of water you will need a glass of this liquid; water the bulbs directly with it.

How to fertilize with minerals

Mineral fertilizers are good because they do not contain foreign impurities. If you fertilize with them, the results from their use are quick and easy to control, but if used carelessly and not following the instructions, they can cause harm. Concentrated solutions can disrupt the soil microflora and burn greenery. All the “forces” of the onion will then be directed towards restoring the feathers, and not the growth of the “turnip”.

Water the onions so that the solution does not get on the greens. The next day after fertilizing the beds, it is better to spill plenty of clean water.

It is not necessary to mix mineral fertilizers based on nitrogen or superphosphate yourself. In gardening stores you can purchase ready-made additives for growing good large onions, which you just need to dilute in water. It could be:

  • product “For onions and garlic” from “Agricola-2”– a universal additive that promotes the growth of good “turnips”. All 3 feedings are carried out with the help of the drug; it promises to fully satisfy the plant’s need for nutrients;
  • « Vegeta" from the same manufacturer, suitable for all vegetables. It saturates the soil with essential elements and increases productivity.

At the first stage, solutions based on ammonia can be used as a mineral fertilizer for onions and as a means against onion flies. To do this, 3 tablespoons of the substance are diluted in 10 liters of water. In the second half of the growing season, ammonia is also used, but in a lower concentration and only for the formation of greenery - the liquid is rich in nitrogen.

Mixed fertilizers

Mixed fertilizers are the most difficult to apply. In order not to harm the plant, you need to know the composition of the soil and accurately calculate the proportions of the components of the solution. To form bulbs, mixed fertilizers are often used like this. When planting, the seedlings are watered with water with urea and slurry in a ratio of 10: 1: 0.25. For the second feeding, take 2 tablespoons of nitrophoska and dilute it in 10 liters of water. The third area is watered with a solution of 20 grams of superphosphate and 10 grams of potassium salt in the same volume of water.

An example of a mixed soil fertilizer, which consists of 16% superphosphate, 50% potassium chloride and ash.

What do you need to feed a large turnip?

In addition to feeding, other factors also influence the formation of large “turnips”:

  • weather. In order for the bulb to gain impressive mass, it needs light. In the southern regions the plant will develop practically without problems, but in the northern regions the root crops will probably be small, it is better to buy less demanding varieties;
  • neighbors in the garden. Experienced gardeners plant onions next to radishes, beets or carrots. Other neighbors and predecessors of onions are described in;
  • moisture. Greenery will tell you about the plant’s “thirst”: dry, yellowing ones ask for water, and pale green ones warn of its excess. During dry periods, onions are usually watered once a week;
  • weeds are capable of “crushing” developing “turnips”, so the beds must be weeded as needed.

conclusions

To grow onions exactly the way you want, you will have to work hard. Even the selection of seedlings here should be thoughtful: study the varieties, sort out the planting material, etc. It is better to base fertilization of bulbs not on the advice of others, but on observation of plants and seedlings. The condition of the greens and root crops will tell you about all their needs, just adjust the feeding scheme in accordance with them, and large “turnips” will not keep you waiting.

Getting it on the head is not so easy if you don’t follow some rules. To form a firm and large onion head, you must be able to carry out the process correctly and on time. feeding the plant nutrients. It is very important to know how and when to apply fertilizer. If possible, try to use two types of fertilizers for fertilizing, but they should be applied a couple of weeks apart so as not to burn the bulbs. Various feedings will help the onions gain the desired shape and successfully resist diseases.

How to feed onions to make them large

The soil where you will plant it has certain requirements. It is best to choose areas where the soil is rich in various nutrients. Loose, non-acidic soil, where there are no weeds and there will be enough light, is suitable for onions. Keep in mind that if your site has very fertile soil, then you should not apply fertilizers to it often and in large quantities, not only mineral, but also organic.

Before planting in the ground, it is recommended to place the sets in a weak solution of potassium manganese for a couple of hours. After this, the water is poured out and the bulbs are placed on burlap to dry. The soil where you will plant the seedlings should be fertilized with rotted manure. This is an important requirement - the manure should not be fresh! For one square meter you need to take half a bucket of rotted manure. A couple of weeks after planting, it is recommended to sprinkle the bed with wood ash, but so that its layer is no more than half a centimeter.

Fertilize onions

After three weeks, the planting must be fertilized with chicken droppings or mullein. But this must be done in compliance with all proportions so as not to harm the plants. For three square meters you should take a bucket of water and dilute a half-liter jar of fertilizer in it. If it is not possible to fertilize the onions with organic fertilizers, then you need to use a urea solution. You usually need to take a couple of spoons of the substance per bucket of water, and then water the plants at the rate of a bucket per four square meters of bed.

It is recommended to carry out the next feeding in the second stage of the onion growing season, about a month after the previous one. At this time, onions have little need for nitrogen; they require phosphorus and potassium. Therefore, it would be advisable to feed the plants with superphosphate (30 g) and the same amount of sulfate, diluted in ten liters of water. This solution should be poured over the onions.

Another feeding can be done by the time the bulb is fully formed. These days the plant needs calcium, and lime is a good source. It will not only allow the bulbs to grow large and strong, but will also reduce the acidity of the soil. Before fertilizing and after fertilizing, the bed with onions must be watered generously with cold water.

There is one more rule that will allow onion heads to grow large - do not tear off the feathers! If you do not do this, then even good feeding will not allow you to get large onions; they will grow very small and sick.
