How to help tomatoes in the flowering period. Top dressing for flowering tomatoes in the open field

For more than twenty years I have been growing tomatoes on my plot. It didn't work out right away, but experience comes with time. There were also mistakes and disappointments from the fact that sometimes it was not possible to get ovaries from already flowering plants.

Of course, the selection of varieties and weather conditions matter, but most of all, proper care and timely feeding of the crop matters.

Of particular importance is the feeding of tomatoes during the flowering period. After all, the quality of the crop and its volume will depend on the provision of the necessary nutrition at this time.

But this does not mean that fertilizers can be used indiscriminately. The result may not justify the investment, but on the contrary, it will bring disappointment.

After all, it is necessary to take into account the characteristics of the soil and monitor the proportions of the fertilizer applied. For chernozems, a smaller amount of top dressing is needed, and for poor loams and sandstones, their amount is much larger.

For the entire growing season, tomatoes are fed at least four times. The most important will be those that are carried out during the flowering of tomatoes and in the process of the formation of ovaries on the bushes.

It was at this time that the lack of nutrients in the soil leads not only to the mass formation of barren flowers, but also the resulting tomatoes are very inferior in size compared to the declared variety.

Lack of nutrition during flowering leads to the fact that the seeds in tomatoes do not ripen. This is a disaster for vegetable growers who collect seeds of varietal crops for further cultivation. After all, such seeds are not able to germinate, or seedlings will be very scarce.

To get more ovaries on tomatoes and increase crop yields, nitrogen, potassium and phosphorus are needed.

The lack of these elements is determined by the characteristic changes in the plant:

  • Insufficient nitrogen content is determined by leaf plates turning yellow from below, then yellowing captures an increasing number of leaves.
  • Phosphorus deficiency gives the leaves a purple color even in the absence of cold weather.
  • A low potassium content results in the loss of color pigment in the leaves, which then turn brown and dry out.

Fruits in such cases are formed with a poorly ripened core and have a sour taste.

What to feed

In order for ovaries to form on tomatoes during flowering, they need nutrition. This is true for greenhouse plants, and for those grown on ridges in open ground.

This is the only way to achieve the ripening of a rich harvest. But it is important to know that an excessive amount of nutrients will have the same negative effect on the culture as a shortage.

For these purposes, mineral and organic top dressings are used.

In addition, top dressing can be applied both under the root and foliar method.

Top dressing with mineral fertilizers

Since the modern market today is replete with a variety of mineral supplements, it is sometimes very difficult to make a choice.

For the proper development of tomatoes, soil depletion in the content of phosphorus and potassium elements should not be allowed. The following are very good as such (shown in the photo):

It is at this time that plants need macro- and microelements the most.

In addition, during this period, the need for nitrogen fertilizers decreases. An exception is weakened seedlings with underdeveloped stems and leaves. This happens with improper care and watering, a lack of nitrogen at the initial stage of development after transplanting seedlings.

Therefore, when answering the question about top dressing for flowering tomatoes, the need for mineral and organic top dressing should be noted. This statement also applies to greenhouse crops and those growing in open beds.

The use of potassium monophosphate also gives a good effect: 15 grams of fertilizer are added to a bucket of water. The solution is enough for a square meter of tomato plantings.

We must not forget at the same time that a large amount of nitrogen can greatly harm the emerging fruits. The reason here is that the growth of green mass, which is facilitated by nitrogen, will lead to an outflow of nutrients from the fruit to the new shoots.

Enriching the soil with nitrogen, it is better to use complexes in which the correct proportions of nutrients are selected, which are so necessary for flowering tomatoes (photo):

When applying mineral supplements, the following conditions should be considered:

  • Nitrogen should be in smaller quantities than phosphorus and potassium;
  • The composition should also contain: sulfur, magnesium, iron, boron and calcium;
  • The content of chlorine in the composition should not be.

organic top dressing

Choosing organic matter for feeding, you can use store-bought preparations, as well as make them yourself.

Many vegetable growers today do not use mineral supplements, choosing organic matter for this purpose. Because such top dressing achieves two goals at once: nutrition and protection of the culture from a wide variety of diseases.

These include:

  • Humates

With the help of humates, you can not only deliver nutrients to plants, but also improve the quality of the soil. If such preparations are used annually, it is possible to obtain consistently high yields even on poor soils.

  • Yeast

With the help of yeast-based top dressing, the growth of tomatoes increases, they develop better. During flowering, this is especially important.

Fertilizer is prepared in the following way:

If the yeast is fresh, then 100 grams are added per liter of slightly warmed water. When foam begins to form, dilute in a bucket of water. The solution is enough for 15 tomato bushes.

If you use dry yeast, then 10 grams is enough per bucket. The solution is infused for two days, and then diluted in a ratio of 1 to 10.

The solution is poured under the bush in such a way as not to pour on the leaves and stems.

Fertilizer with yeast is combined with fertilizing with ash.

For top dressing, wood, straw or peat ash is used, which contains calcium, phosphorus and magnesium, which are so necessary for tomatoes during flowering.

In addition, ash helps fight many pests. But you must be aware that a tree that has been treated with various compounds (paints, varnishes, glue) is not good.

Ash is applied in the following way:

Sprinkle one tablespoon under each plant once a week. Prepare an infusion of 100 grams of the substance in a bucket of water. Watering is carried out once every two weeks: at the rate of 0.5 liters for each bush.

Just 3-4 drops of the substance are enough to dilute in 10 liters of water to get a nutrient solution that helps to increase the number of ovaries and the fastest ripening of tomatoes.

  • Herbal infusion

For feeding tomatoes during flowering, an infusion of grass gives a very good effect.

Prepare the infusion in the following way:

  • In a 200 liter barrel lay 50 kilograms of nettle (5 buckets)
  • Add a bucket of mullein
  • Per kilogram of fresh yeast and wood ash
  • 3 liters of fermented milk drink (kefir, whey, milk)
  • Top up with water to full volume

The infusion is kept for two weeks, watering is carried out at the rate of 1 liter of infusion per bucket of water. A liter of liquid is used per plant.

Foliar fertilizers

Such dressings are very effective if adverse conditions arise.

Prepare the solution in the following way:

Three liters of water add 300 grams of ash and boil for about half an hour. The volume is brought to 10 liters, then a piece of grated laundry soap is dissolved in it and infused for about 24 hours.

The resulting solution is sprayed on the leaf and flowers. The effect of the use of such a tool becomes noticeable almost immediately.

For feeding, prepare a solution in milk. For this: 2 tbsp. spoons of iodine, 1 tbsp. a spoonful of hydrogen peroxide is mixed in a liter of milk. Bring the volume of liquid to 10 liters, diluting with water.

By spraying with such a solution, a double effect is achieved: the nutrition of flowering tomatoes and their protection from diseases.

  • Boric acid solution

Top dressing with boric acid is used at high stable temperatures, +30 and above. At such temperatures, ovaries do not form on flowering tomatoes.

When fertilizing with boric acid, the formation of flowers and the formation of ovaries in a greenhouse are improved, and the ripening of fruits is accelerated.

To prepare the solution: Art. a spoonful of the substance is dissolved in a cup of hot water and diluted in 10 liters of water.

Spraying a flowering crop is carried out every 7-10 days.

conclusions

It is possible and necessary to feed tomatoes during flowering. For this, it is possible to use both organic and mineral fertilizers.

Since there are a large number of various fertilizers, each gardener has the right to decide independently which of the methods and methods to apply in the greenhouse and in the open field.

At the same time, it is necessary to clearly know that fertilizers should be applied, adhering to the instructions. An excess of macro- and microelements in the soil can also lead to inhibition in development and shedding of ovaries, which will adversely affect both the quality and quantity of the future tomato crop.

Tomatoes need macronutrients and nutrients. For strong seedlings and a rich harvest, three elements are necessary: nitrogen (N), potassium (K) and phosphorus (P). When top dressing, tomatoes during flowering and fruiting should also receive magnesium, calcium, manganese, sulfur, iron, boron, molybdenum, cobalt and zinc.

Macronutrients in feeding tomatoes during flowering and fruit set play a big role:

  • enrich the soil and improve seed germination;
  • activate the vital processes of the plant;
  • improve the ovary of fruits, reduce the number of barren flowers;
  • participate in the synthesis of vitamins, proteins and carbohydrates;
  • increase the resistance of crops to sudden changes in temperature, to drought, to diseases and pests.

Signs of deficiency of macro- and microelements in tomatoes

The appearance of the bushes will make it clear whether it is necessary to feed the tomatoes:

  1. The leaves become smaller and turn yellow, the veins on the underside become blue-red - lack of nitrogen.
  2. The stem is thin, the underside of the leaf is red-violet, the ovary crumbles, the vegetables are small - a lack of phosphorus.
  3. New shoots are wrinkled, covered with bronze spots, the crop ripens unevenly - potassium deficiency.
  4. The leaves are brittle, twist up, fall prematurely - not enough magnesium.
  5. Stem growth stops early, flowers fall off - lack of calcium.
  6. The lower old shoots turn yellow sharply, the stem thickens - a lack of sulfur.
  7. The growing point of the stem turns black, the fruits become ugly, tissues in vegetables die - there is little boron.
  8. Pale yellow spots appear on the upper young leaves - a lack of manganese.
  9. Yellowing of leaves with iron deficiency is similar to nitrogen starvation.

Top dressing tomato during flowering and fruiting

Before the appearance of buds, a healthy seedling already has 6-8 pairs of leaves. The bushes should be dark green in color, not overgrown, with a thick stem and large leaves. This will serve as a signal that the nitrogen content in tomato top dressing needs to be reduced. With an excess of nitrogen, the seedling will develop a green mass, extra stepchildren will form, and the fruits will not be tied.

For this vegetable, when the crop ripens, phosphorus and also potassium are needed. It is necessary to feed tomatoes during the period of flowering and fruit growth once every twenty days. The best way to apply potassium and phosphorus preparations at this stage is to water under the root with a diluted concentrate.

You can alternate mineral and organic substances. Before applying the drug under the root, the plant should be shed a little with clean water so as not to burn the roots with chemicals. It is also recommended to apply zinc and boron, magnesium and calcium by foliar spraying of bushes.

How can you feed tomatoes during flowering and fruit ripening:

  1. "Potassium monophosphate". Contains 46% phosphorus, 34% potassium. The consumption rate is 10 - 15g per 10 liters.
  2. "Diammophos". In the composition - N9:K25:P25. The scheme of dilution of the substance is 20 g per bucket of water.
  3. Double superphosphate. Contains phosphorus 46%, as well as calcium sulfate, ammonium and iron phosphates. Dilute 100g of superphosphate in 10 liters of warm water.

Complex fertilizers

What fertilizer do tomatoes need for good fruiting? If the bushes develop normally, they do not have signs of an excess of nitrogen, then complex preparations can be used. They are easily soluble in water, suitable for leaf processing and root irrigation, contain trace elements in the right concentration. Experts recommend:

  1. Kemira Lux. Packing - 100g. Suitable for outdoor and greenhouse use. It contains nitrogen 16%, potassium 27%, phosphorus 20.6% and trace elements. Dilute - 10g per 10 liters.
  2. "A clean slate for tomatoes." Packaging - 1.2kg, 350g and 100g. Mineral concentrate with nitrogen 16%, phosphorus 8.7%, potassium 20%. Consumption - 10g per 5 liters.
  3. "Fasco Baby for tomatoes." Composed of phosphorus, nitrogen, potassium and organic matter. Available in 50g and 250ml packaging. Consumption rate - 10g per bucket of liquid.

Fertilizers for foliar processing

Top dressing of tomatoes during the fruiting period includes spraying fertilizers on the leaf. They contain all trace elements in a form easily accessible to plants, which are absorbed by 90% after application. Preparations for foliar feeding of tomatoes during the growth of fruits in the greenhouse and in the open field are available in liquid form and in powder form. The role of such trace elements is great:

  • accelerate the ovary;
  • improve taste;
  • increase the shelf life of the crop;
  • increases resistance to disease.

  1. "Quantum for vegetable crops". A complex, highly concentrated chelate. Contains nitrogen 5%, phosphorus 5%, potassium 7%, iron, zinc, copper, magnesium, boron and humic and amino acids. Apply twice: before budding and three weeks after the first treatment. The consumption rate is 30 ml per 10 liters of water.
  2. "Reacom for tomatoes". Chelated concentrate containing phosphorus 40%, potassium 60%, sulfur, iron, molybdenum, magnesium, copper, boron. Consumption rate - 25g per 10 liters of water.
  3. "Boric acid". Consumption rate - 10g per 10 liters of water. Why is the trace element boron needed?
  • promotes pollination and formation of the ovary;
  • increases yield up to 20%;
  • promotes better absorption of calcium.

The role of humate for top dressing of tomatoes

Humates are substances with humic acids. Humic substances are extracted from peat and contain about 50 macro- and microelements. Some elements of these acids are not absorbed by crops from the soil, so they are converted into water-soluble potassium or sodium salts.

Humate preparations when feeding a tomato during fruiting in a greenhouse and open ground are not recommended to be used simultaneously with phosphorus substances and calcium nitrate

Humates should be applied three weeks before the first harvest.. For spraying, use a filtered concentrate without particles of raw materials.

How humates affect the plant:

  • prevent shedding of the ovary;
  • accelerate the ripening of vegetables;
  • reduce the content of nitrates and radionuclides in the crop.

What humate preparations can be used to feed tomatoes for quick fruit ripening in June - August:

  1. "Potassium Humate", "Sodium Humate" and "Humate + 7" - available in dry and liquid form. The concentration of the active substance varies from manufacturer to manufacturer, so follow the instructions on the package.
  2. "Hera for tomatoes" is a humated, granular substance. Contains the main elements and salts of humic acids. The drug is applied in dry form at a dosage of 5 g per bush.

Organic fertilizer for tomatoes

Such substances are obtained as a result of the processing of waste products of plants and animals. All types of organic fertilizers are suitable for feeding tomatoes during fruiting. Consider the main types of organics:

  1. Wood ash. It is obtained in the process of burning wood, so there is no nitrogen in it. Contains potassium in high concentration, as well as calcium, magnesium, molybdenum, manganese and boron. Method of application - watering under the root of 100 g of ash per 10 liters of water.
  2. Biohumus. Foliage, grass or manure processed by earthworms. Contains water-soluble form of elements, amino acids and humic substances. For top dressing during flowering and growth of tomato fruits, you can use the preparation "Humisol". It increases productivity, enhances taste. The consumption rate for spraying is 250 ml per 10 liters of water.
  3. Cow and horse manure. It contains the necessary elements for crops. Use dry manure. 1 kg of humus insist in 10 liters of water for 5 days. Further, each liter of the resulting liquid is diluted in a bucket of water. Apply 1 liter of the finished liquid under the bushes.
  4. Bird droppings. It contains three to four times more useful trace elements, so you need to dilute the concentrate 1 liter per 20 liters of water.

Useful tips for feeding tomatoes in the greenhouse and in the open field

Basic moments:

  1. Choose complex compositions with potassium, phosphorus, boron, magnesium. Use preparations with a minimum nitrogen content in the composition.
  2. Alternate the application of mineral and organic substances.
  3. To accelerate the growth of fruits, remove the leaves on the stem to the first brush with the ovary and pinch the tops of the shoot on which the vegetables are formed.
  4. Apply fertilizer for digging the soil in the fall. Use 50g of superphosphate and 20g of potassium sulfate per square meter of land.
  5. In the spring, when planting seedlings, add 10 g of nitroammophoska to each well.
  6. Plant green manure in the place where this vegetable will grow. Plants such as oil radish, lupine, phacelia, mustard, alfalfa improve the structure of the soil, accumulate nutrients in it.
  7. In polycarbonate greenhouses, after leaf processing, it is imperative to ventilate the seedlings; close the greenhouse when the leaves are completely dry.
  8. Observe the norms of dilution of chemicals according to the instructions, do not exceed the number of treatments.
  9. Ensure regular and sufficient watering during the period of budding and ripening of the crop. With a lack of watering, a barren flower is formed, and the ovary crumbles.

So, tomatoes during flowering and fruiting need macro- and microelements. Their lack in the soil will lead to shedding of the ovary, weak flowering and fruiting. During this period, the dose of nitrogen preparations should be reduced and formulations with a high content of potassium and phosphorus should be used.

It is better to enrich the bushes with magnesium, boron, calcium, sulfur, iron by spraying on the leaf. Thanks to this method, the necessary elements are quickly absorbed by the plant through the leaf blade.

It is also recommended to alternate the application of mineral and organic dressings during flowering and fruit ripening. For convenience, you can draw up a scheme for fertilizing vegetables for the entire season with a list of selected preparations. In it, paint the application rates for chemicals and organics and calculate how many drugs you need to purchase.

And for those who have been growing these vegetables for more than a year, it is interesting to learn something new. Useful information will help you get the best harvest on your plots.

Beginning vegetable growers have many questions about caring for tomatoes, including how to feed tomatoes during flowering.

Tomatoes during flowering, as in any other period, need three nutrients. These are nitrogen, potassium and phosphorus. These trace elements are essential for the growth and development of tomatoes.

You can understand that the plant lacks nitrogen by the state of the leaves - they turn yellow. Yellowing begins from the lower leaves and gradually rises to the top.

If the leaves begin to turn purple, then there may be a lack of phosphorus. But before introducing this element into the soil, you need to make sure that the tomatoes are not cold, as the purple leaves can also turn from the cold.

The lack of potassium is manifested by the fact that the leaves change their color to a lighter one, and they lighten from the tip. Gradually, the color changes to brown, and then the leaves dry up. If you do not feed the tomatoes on time, during the flowering period, and then at the time of ripening, then the fruits will grow sour, and their middle will not ripen.

During the flowering period, the bushes can be sprayed with a solution of water with one of the following substances:

  • urea;
  • boric acid;
  • vinegar;
  • saltpeter;
  • serum.

The solution is prepared from 10 liters of water and 1 tbsp. l. any of these fertilizers.

Spraying during the flowering period contributes to better formation of ovaries, which subsequently leads to more fruits.

For spraying, it is necessary to choose the evening hours, when the heat is already subsiding. You can spend it on cloudy days. And if you do this during the hours when the sun is shining, you can get burns on the leaves from its rays. And the liquid in the heat evaporates too quickly, and the plant does not receive the right amount of nutrients.

Tomatoes during flowering, as in any other period, need three nutrients. These are nitrogen, potassium and phosphorus

Top dressing of tomatoes during flowering is also carried out by watering. And this should be done at a time when the sun no longer shines, that is, in the evenings or in cloudy weather. If you water the tomatoes in the heat, then the moisture evaporates too quickly from the soil, and the solution that gets on the leaves can burn them.

Plants can be fed with a mixture of 20 g of any phosphate fertilizer, 15 g of potassium salt, 12 g of saltpeter. This amount is enough for 1 m² of plantings. The mixture is applied between the bushes of flowering tomatoes.

In garden stores, you can also purchase ready-made fertilizer formulations designed to feed flowering plants.

How to feed plants in a greenhouse

Top dressing of tomatoes growing in a greenhouse requires caution. This is especially true for fertilizers containing nitrogen. Their dosage should be approached especially carefully. When fertilizing in liquid form, it is necessary to monitor the temperature of the solution. Water for him should be warm. Tomato roots suffer from temperature changes.

Heteroauxin is used to stimulate growth and better ovary formation. It is diluted in water at the rate of 20 g per 1 liter. All brushes of flowering tomatoes are sprayed with the prepared solution. This helps to grow fruits with a high content of vitamin C and sugar.

Tomato flowering is the period when you can feed the plants with organic fertilizers. Before using chicken manure or cow manure, it is necessary to water the plants in advance, that is, if top dressing is planned in the evening, then the bushes should be well watered in the morning.

Mullein is the best fertilizer for tomatoes. A solution for feeding a flowering vegetable is prepared as follows:

  • dissolve 1 liter of manure in 10 liters of water;
  • add 0.5 cups of wood ash and 1.5 tbsp. l. superphosphate;
  • apply the prepared fertilizer under each bush at the rate of 0.5 liters per plant.

A solution of chicken manure is prepared as follows:

  • pour dry litter into the bucket by about 1/3 of the volume;
  • pour water to the edge of the bucket;
  • insist 1 week;
  • for irrigation, dilute 1 liter of the prepared infusion in 1 bucket of water, adding about 1 liter of solution under each bush.

What else can you feed flowering tomatoes

Wood ash is an excellent top dressing for flowering tomatoes. It is introduced into the grooves, which should be made along the beds with planted bushes at a distance of 10-15 cm. The introduced ash is sprinkled with earth, and then watered.

You can use not one ash, but a mixture of several fertilizers. To prepare it, you will need 10 liters of water, 1 liter of wood ash, 10 g of boric acid, a small bottle of iodine. All components are mixed and infused for a day. Under one bush of flowering vegetables, 1 liter of the prepared mixture is poured.

When asked how to feed tomatoes during the flowering period, the answer can also be this - yeast. The composition is prepared from 100 g of live yeast, 10 liters of water, 2 tbsp. l. Sahara. Everything is mixed and infused for a day or more. Tomato bushes are watered with the prepared mixture, diluted with water at the rate of 1 cup of sourdough per 10 liters of water.

Top dressing of tomatoes during flowering is also carried out by watering

Even weed grass will help in feeding tomatoes. The nutrient mixture is being prepared in a barrel. 5 kg of any grass (it can be both nettle and lawn grass) should be finely chopped, poured into a barrel. Add 10 liters of manure, 1 glass of wood ash. Pour about 5 buckets of water into the barrel and stir everything. Let the mixture brew for 2 weeks, but be sure to stir it at least once a day. Then add the same amount of water. Water the tomatoes with the prepared composition - about 2 liters under each bush.

Top dressing of tomatoes during flowering is very important.

There are several ways to carry it out and quite a few different means for this purpose.

This article will help you understand this issue and choose the most appropriate method of feeding.

Have your tomatoes bloomed yet? Do not waste your time, have time to properly feed them and they will reward you with a bountiful harvest!

The main reason why you should not neglect feeding at this time is that lack of nutrition can lead to the formation of a large number of empty flowers in the plant.

They will take nutrients from the developing fruits, which will lead to a significant decrease in the volume of the crop.

It can also be very bad for tomato seeds.. Seeds of weakened plants germinate poorly, seedlings from them are weak and often sick.

So if you prefer to grow tomatoes from your seeds, pay attention to top dressing during this period.

Important: Another possible consequence of a lack of nutrition during flowering can be a sour taste of tomatoes and a hard core.

Signs of the need for feeding

There is three main signs that you should hurry with top dressing:

  • the lower leaves begin to turn yellow and this process spreads up the stem;
  • the leaves have a purple hue;
  • leaves turn brown and wither quickly;
  • , in this case they need specialized top dressing.

Should I feed when they are in bud or already in bloom?

The best moment for top dressing is the period of abundant flowering, when the first brush blooms in some places, while the second brush is already blooming in others. That is, this is no longer the period of budding and the very first flowers, but the fruits have not yet begun to set.

What can be fertilized to have more buds?

There are three main types of fertilizer for tomatoes:


Complex fertilizers

What are the most popular complex fertilizers? Here is a list of drugs that experienced gardeners prefer:

What to look for when choosing complex fertilizers for flowering tomatoes? Please note that drugs must meet the following requirements:

  • potassium, as well as phosphorus should be much more than nitrogen;
  • the presence of: sulfur, calcium, magnesium, iron is very important;
  • the presence of humates is desirable;
  • chlorine or its constituents should be avoided.

mineral

For tomatoes, first of all, a sufficient amount of phosphorus is very important, as well as potassium, so popular funds compensate for their deficit.

We list the main ones:

  • simple, as well as granular superphosphate. Contains from 16 to 19% phosphorus;
  • double superphosphate has 50% phosphorus;
  • potassium salt - from 30 to 40% potassium;
  • potassium chloride - 55% potassium;
  • potassium sulfate - about 50%.

Important: potassium chloride should be used only when the plants have already developed a powerful root system, since it negatively affects its development.

Organic substances - without "chemistry"

More and more gardeners are striving to grow completely safe “chemical-free” vegetables on their plot, so organic fertilizers are becoming more and more popular.

In addition to absolute environmental cleanliness, they have other advantages. They can be used not only for plant nutrition, but also for disease control..

The most common tomato disease is late blight, which manifests itself especially strongly with high humidity.

  • humates;
  • yeast;
  • ash;
  • boric acid;

Humates improve the soil. This is especially true in poor soils.

Humates also have other useful properties: increase the immunity of plants, lengthen the period of fruiting, strengthen the root system. Experienced gardeners usually recommend using Kuznetsov's GUMI (you need 2 spoons per bucket). Also popular on the market: "Humate +7", 2Gumat-Universal, "Lignohumate".

Yeast. They should be used to water plants that are stunted. To prepare the solution, you need to dilute 100 g of yeast in 1 liter of warm water. After a few hours, this solution is diluted in a bucket of water. On average, one bush goes 0.5 liters.

Important: yeast reduces calcium, as well as potassium in the soil, therefore it is recommended to additionally fertilize the plants with ash after top dressing.

Ash is a source of many useful elements: calcium, phosphorus, magnesium, potassium, etc.

You can use it in different ways:

  • sprinkle near the bush (2 spoons, every 12-14 days);
  • make a solution and then water 2 times a month;
  • make a solution for treating the leaves and stems of tomatoes against harmful insects.

The solution that is used for root dressing can be prepared by adding 100 grams of ash to a bucket of water.

Stir again before use as the ash settles quickly. It is enough to use 0.5 liters per bush.

For foliar top dressing, you need to dissolve the sifted ash in 3 liters of water. Then boil the solution for 30 minutes, dissolve in a bucket, add a small amount of laundry soap, leave for a day.

Boric acid helps tomatoes grow faster in conditions of elevated temperatures: in greenhouses or in southern latitudes. With its lack, tomatoes are poorly tied into fruits.

To prepare a solution of boric acid, you need to dissolve 10 grams of powder in a small amount of hot water, and then add to 10 liters of cool water. It is necessary to process from the period of budding and further until the formation of ovaries. Repeat every week.

"Folk remedies

The most popular such remedy is herbal infusion.

Here, its most complete version will be described, which allows it to be used not only for nutrition, but also for plant protection.

The following ingredients are put in a 200 liter barrel: five buckets of grass (preferably nettle), 1 bucket of cow dung or half bird dung, 1 kilogram of ash, 3 liters of milk.

It is better to insist up to two weeks.

When watering, use 1 liter per bush.

This solution has everything that tomatoes need and at the same time in a well-digestible form.

How to encourage more fruit set

For this it is best to use diluted iodine. It not only helps fruit set, but also increases the number of ovaries and promotes the formation of more juicy fruits.

There is an easy way to make it. You just need to dilute 3 drops in 10 liters of water and pour under the bush.

But there is a more complicated way to prepare the solution, it is useful in the fight against late blight and is used for foliar treatment. To create it, you need to dilute 30 drops of iodine in 1 liter of milk, add a spoonful of hydrogen peroxide and dissolve the resulting mixture in a bucket of water.

We feed foliar and root methods

There are foliar and root feeding methods. Roots are ordinary watering, only fertilizers are used instead of water.

Foliar - this is spraying on the leaves certain drugs.

Please note that spraying plants with drugs is possible only in certain weather otherwise it could cause serious damage.

Each type of top dressing has its own advantages and disadvantages, and the purposes of their use may also differ.

If you are using ready-made fertilizers, the recommended method of application should be indicated on the packaging.

If you prefer organic or "folk" remedies, read about it in the materials completely dedicated to them.

Features of processing at the stage of budding and "in bloom"

It must be taken into account that excess fertilizer is harmful. It can be much more dangerous than lack of nutrition.. Because of it, the inflorescences die and the ovaries do not have time to form. Therefore, it is very important to fertilize plants during this period strictly observing the recommended dosage of drugs.

It is also very important to know that when tomatoes bloom, they do not need to be fed with fertilizers, in which the main element is nitrogen. This will lead to abundant growth of leaves and shoots, and too many plant resources will be spent on them.

Flowering will then be weak or the tomatoes will not bloom at all.

Remember, at this moment in June, the emphasis is on fertilizers, where potassium and phosphorus predominate.

Super remedy for this period

Oddly enough, but the best is to recognize the "folk" remedy - herbal infusion.

Indeed, in it, firstly, only absolutely safe substances are used, and, secondly, it is truly universal and multi-component - no additional fertilizers are needed for it.

However, there are also disadvantages: a 200-liter barrel and animal manure can sometimes be difficult to get, more difficult than a bag from a store.

Yet It is worth noting the complex fertilizer "Universal". It really lives up to its name and, according to many gardeners, one of the best on the market. Its disadvantage is the lack of calcium.

When tomatoes bloom, the gardener faces new challenges. The most common problems are falling flowers and ovaries. These complications must be urgently eliminated by spraying with special means.

What and why to spray

Flowering is a new stage in the development of a tomato, at which it will need a slightly different set of micro and macro elements than in the initial stages of growth. Now you should not be zealous, offering the plant nitrogen, which contributes to the growth of green mass. It's time to switch the tomato to fruiting mode.

Tomato flowers are self-pollinating, anthers and pistil are on the same flower

With the help of foliar dressings, a chemical signal is given to the tomato: it's time to set fruit. At this stage, top dressing is relevant, containing:

  • phosphorus;
  • potassium;
  • magnesium;
  • calcium;
  • iron;
  • zinc.

A small number of ovaries on a tomato is often associated with a deficiency of these substances. The best way to apply these elements is by spraying.

In order for the tomato to set the maximum number of fruits, it needs to provide decent nutrition with the help of foliar dressings.

Boric acid

If the flowers fall off, do not postpone the processing of tomatoes with boron, so as not to be left without a crop. This substance helps plants to extract from the soil and assimilate other beneficial minerals. Boron is not a very mobile element, even if there is enough of it in the roots of the plant, then the top and flowers may be deficient.

Boric acid solution preparation

  1. Dissolve ½ tsp. (2 g) boric acid powder in a liter jar of hot water at 50°C.
  2. Pour into a bucket, add 9 liters of water and stir.

The above concentration applies to tomatoes growing on sandy soils where boron is deficient. On calcareous soils, where the element is poorly absorbed, this proportion is also suitable. But on fertile, well-fertilized land, take half the dose of acid: 1 g per bucket. Spray tomatoes with boron only 1 time during flowering. Scientists have proven that boric acid is quite poisonous in large doses, so it is often dangerous to treat it and exceed dosages.

The lethal dose of boric acid for an adult when taken orally is 5–20 g. Even excessive external use can cause poisoning. Since 1987, this antiseptic has been banned for children and pregnant women.

Dry boric acid dissolves only in very hot water.

Biostimulants

Over the past 10 years, agricultural firms have launched the production of a large number of fruit formation stimulants, for example:

  • Ovary;
  • Bud;
  • Gibbersib;
  • Pollen;
  • ripener;
  • Tomaton.

These preparations contain gibberellins - plant hormones that stimulate an increase in yield and quality of fruits. Agro-sellers claim that it is realistic to increase the number of tomatoes by 20-35%. The frequency of treatments is indicated on the packaging of the drugs.

Gibberellins were discovered by a Japanese scientist in 1926 while investigating rice disease.

Stimulant Ovary increases the resistance of tomatoes to diseases With the help of Pollen, fruits are tied even under unfavorable conditions Stimulator Tomaton contains auxin and is available in ampoules

Ash

At the same time, it is possible to feed tomatoes with potassium, phosphorus, magnesium, calcium and boron with the help of wood ash alone. Foliar feeding is preferable, since through the leaves the plant absorbs the necessary elements faster. This safe fertilizer, when applied during the flowering of tomatoes, guarantees the production of large and sweet fruits.

Preparation of tank mix from ash

  1. Pour 300 g of sifted ash with 3 liters of water and boil for half an hour.
  2. Pour the broth into a ten-liter bucket, add water to the top and leave for a day.
  3. Drain off the sediment. Add 1 tbsp. a spoonful of laundry soap shavings for good adhesion, stir.

It is permissible to spray the plants with the above agent at least every 10 days. Such treatments also restrain tomato diseases. The ash solution forms an alkaline film, and this prevents the spores of pathogenic bacteria and fungi from germinating on the leaves. Spray the leaves correctly from the bottom and top sides.

Mineral fertilizers

The setting and rapid growth of fruits is also stimulated by inorganic store-bought fertilizers.

Chelates

Chelated fertilizers are instantly absorbed by the leaf plate. Therefore, they are useful for spraying during the flowering period, when you need to send an unambiguous signal to the plant about the need to tie more tomatoes. Choose complex microfertilizers in chelated form containing boron, magnesium, zinc, for example:

  • Station wagon from the company "Kimira";
  • Microvit from Elite Agrosystems.

Fertilizer wagon from the company "Kimira" dissolves well in water

Superphosphate and monophosphate

Phosphorus and potassium fertilizers are also suitable for increasing the number and size of fruits in a tomato brush. Usually refer to superphosphate and potassium monophosphate. The advantage of leaf dressing with minerals is the impossibility of overfeeding, the plant will take only the required amount.

Preparation of superphosphate extract for spraying

  1. Pour 1 tbsp. l. superphosphate with a liter of hot water.
  2. Leave for a day, stirring occasionally.
  3. Dilute the resulting solution in 9 liters of water.

Potassium monophosphate is also very effective - an expensive product that gives maximum yield growth. For foliar feeding, 5 g of the substance (a teaspoon) is taken per bucket.

Tomatoes are sprayed with the listed fertilizers 1-3 times per season during flowering and fruit formation.

The size of future fruits depends not only on top dressing, but also on the tomato variety.

During the flowering period of tomatoes, of all the above means, the best results for me are fertilizing with fruit formation stimulants with gibberellins. Fruit setting is excellent. I collect much more tomatoes than without phytohormone treatments. And after top dressing with ashes, I notice an increase in the sweetness of the fruit.

Iodine and potassium permanganate

If there is a need to carry out the prevention of diseases, during the flowering period they are armed with safe pharmaceutical products. Iodine is widely used: 60 drops per 10 liters. Less often turn to potassium permanganate: ¼ tsp. on a bucket. For better adhesion, a glass of milk is added to the tank mix.

It is not advisable to treat tomatoes for diseases with boric acid. Ordinary potassium permanganate and has a stronger disinfecting effect.

Potassium permanganate is effective for prevention, but it is of little use for the treatment of already developed tomato diseases.

What cannot be handled

Flowering plants should not be sprayed with agrochemicals. Harmful substances can get into the set fruits. It is especially not advised to use pesticides of I and II hazard classes. This information is indicated on the packaging of drugs. In addition, although tomatoes self-pollinate, the flowers attract pollinating insects. Therefore, treatments even with biological insecticides are strictly not recommended so as not to kill bees and bumblebees.

As a novice tomato grower, I considered copper sulphate to be completely harmless to tomatoes. But it turned out that in high doses, the chemical exhibits phytotoxicity. With preventive spraying with a high concentration solution, flowers began to fall off en masse in my tomatoes. As the specialist later explained to me, it was an ordinary chemical burn. The tissues of the plant withered and dropped everything that had become dead. I no longer use vitriol during flowering.

If you are interested in a bountiful harvest, spraying tomatoes during the flowering period is simply necessary. Only you need to choose safe drugs.
