What to do with flowering tomatoes. Proper feeding of tomatoes during flowering

Gardeners who plant tomatoes dream not only of getting big yields. I want the fruits to grow large, of excellent quality and excellent taste: juicy, sugary. To do this, you need to know how to feed the tomatoes, what preparations to use for this and why it is important to do this during the periods of flowering and fruiting.

Top dressing of tomatoes in the greenhouse

Growing in greenhouses has its own peculiarities. Plants are indoors, it is necessary to create conditions for their normal growth, to provide useful components. Top dressing of tomatoes during flowering and fruiting saturates:

nitrogen, necessary at the initial stage, helping the formation of buds;
phosphorus, forming roots, accelerating flowering, fruit set, increasing productivity;
potassium, which is involved in the formation of stems, contributing to faster ripening of fruits.

The main thing is how to feed the tomatoes in the greenhouse, how to do it right. Experienced gardeners fertilize plants late in the evening, use only warm water to prepare the solution, pour one liter under the bush. A good harvest requires doing this several times during the season, using root and foliar nutrition. When and how to feed tomatoes in a greenhouse?

Fertilize plants in the following order:

The first time the bushes are fed 14 days after planting the seedlings. Use a preparation containing nitrogen - urea: dissolve a spoon in a large bucket of water. Another option is to use liquid mullein: 500 grams per 8 liters.
The second time the plants are fed in a week with exactly the same compositions.

How to feed tomatoes in the greenhouse further? The third time they fertilize when the fruits begin to set - after 2 weeks. Plants need potassium at this time: it is recommended to make grooves along the ridge, sprinkle with ash, then bury. This will increase productivity. Use the composition, which watered the soil under the plant - two liters for each bush. The tool includes:

10 liters of water;
two tablespoons of ash, one - superphosphate.

How to fertilize tomatoes in the greenhouse next? The fourth time they are fed during the flowering of the third brush. Apply potassium humate - one spoon per bucket. At the time of fruiting, to improve the ripening process, a fifth is done - foliar top dressing: a weak solution of superphosphate. Well stimulates the growth of fruits fertilizer prepared using yeast. Recipe:

take 20 grams of yeast;
add 2 tablespoons of sugar;
pour 10 liters of water;
leave for a day for fermentation;
dilute in 50 liters.

Mineral fertilizers for tomatoes in the greenhouse

It is not worth using only organic fertilizers to feed tomatoes during flowering and fruiting. Plants also need minerals. Good care, watering and proper nutrition will provide you with an excellent harvest of mouth-watering fruits. Recommend the use of drugs:

nitrogen: urea, ammonium nitrate - from the beginning of growth;
phosphorus: superphosphate - when fruit is set;
potash: potassium sulfate - at the time of ripening;
complex, containing all the elements: nitroammophoska, nitrofoska.

Top dressing of tomatoes in the open field

Plants planted in an open area are in more difficult conditions than greenhouse ones. They are affected by temperature changes, they are more sensitive to watering and require special care. Top dressing of tomatoes in the open field and in the greenhouse has differences. If the seedlings are weak, the first time nitrogen can be fertilized after 3 days. In case of good rooting of plants, it is better not to overfeed the bushes. It is worth removing nitrogen fertilizers when tomatoes are poorly tied.

The second time they are fed with potassium during the flowering of the first brush - they use dry ash: they scatter it under the bushes or bury it. Green fertilizer, which is obtained by fermenting nettles for ten days, helps fruiting well. Add a liter of the composition to a bucket of water. On the third, when the second brush blooms, a solution of potassium humate is used - a spoon in a bucket. The fourth top dressing is obligatory - phosphorus: after 2 weeks using the same amount of superphosphate.

Mineral fertilizer for tomatoes

Tomatoes growing in an open area require mineral fertilizers all the time of growth, but especially during flowering and fruiting. The preparations are diluted with water or scattered dry. They are used in conjunction with fertilizing with organic fertilizers:

at the first: 20 grams of superphosphate is added to the mullein solution - it improves the formation of roots;
the second is a complex fertilizer: 5 g of potassium sulfate, 50 g of nitroammophoska per square meter;
the third and following: once every ten days with the composition "Stimulus-1" - for the formation of fruits, accelerated ripening.

Foliar top dressing of tomatoes

Summer top dressing of tomatoes during flowering and fruiting is done both by watering and spraying. It is held once every ten days. Foliar nutrition works in different ways:

stimulates the growth of fruits, accelerates the ripening of a teaspoon of superphosphate, diluted in a bucket of water, "Humisol";
improves the process of ovary boric acid in the same proportions as described above;
when flowering and reddening of the fruits, an ash solution is effective: 0.4 kg of ash, filled with two liters of warm water, "Zircon";
from late blight - a vial of iodine per 8 liters or a liter of serum diluted in the same volume.

How to water tomatoes for a good harvest

Gardeners use proven folk recipes to get an excellent harvest. Increases the weight of the fetus, improves the taste of iodine. Water the plants by adding 4 drops of the solution to the bucket. Feeding tomatoes with one percent boric acid is popular. A good effect is given by fertilizer under the root during flowering, during fruiting, with home-made complex fertilizer. For cooking you need:

take a barrel of 200 liters;
fill a third with dandelion leaves, nettles;
put 2 buckets of manure;
to fill with water;
last 2 weeks.

Of the funds that are sold, drugs help to grow a generous harvest:

"Kemira-lux" - used during the growth of tomatoes;
"Universal" - used only in dry form, contains many trace elements;
"Mortar" - effective for foliar nutrition;
"Orton Growth" - accelerates development;
"Fortress" - promotes rooting, stimulates growth.

Video: feeding tomatoes during flowering

Sometimes it happens that vegetables need a little help to get a good harvest. For example, when tomatoes begin to bear fruit, they may need top dressing: in the event that the soil is depleted, tomatoes have been grown on the site for many years or such manipulations have not been carried out in advance. In any case, you need to understand that for each growing season there is a suitable type of fertilizer that will not harm the plant and will make up for exactly those missing elements that it needs at the moment.

When are they fed?

During the season, top dressing of tomatoes is carried out 3 times: at the beginning of the growing season, during flowering and the beginning of the ovary, during the period of mass fruiting.

At the beginning of the growing season, young bushes need nitrogen. Nitrogen, the main element that stimulates the growth of green mass, is consumed very heavily during the period of its active development. It is logical that at this time fertilizers are added to the soil that contain it in large quantities: saltpeter, urea, etc. Nitrogen is introduced 15 days after planting in the soil. Then feeding is repeated, 2 weeks after the first.
During the flowering period - at this time, tomatoes need phosphorus and potassium. It is good to use yeast top dressing during the flowering period, superphosphate, a mixture of iodine and milk, spraying with boric water will also have a good effect on the fruit set.
Mass fruiting - here you will need phosphorus and potassium. Fertilizers for the last two top dressings are used the same, the only difference, perhaps, is that during the fruiting period, any kind of fertilizer should be minimized or applied if necessary.

Features of feeding during fruiting

During fruiting, you need to apply fertilizers rich in phosphorus and potassium, you should refrain from nitrogen at this time. It is well known that nitrogen can increase the size of fruits and their number, but at the same time, it tends to accumulate in the flesh of vegetables, thereby making them dangerous to human health. Next, we will consider how to feed tomatoes using folk remedies and chemicals.

Did you know? The peel of tomatoes contains carotene, just like carrots. The secret of why tomatoes are red and not orange, like carrots, lies in the fact that anthocyanin is also present in the peel of tomatoes, which is responsible for the purple color. The balance of these two pigments gives red.

Folk remedies

Let's first figure out how to feed tomatoes without resorting to the use of chemical fertilizers.

A mixture of ash, iodine and boric acid. Ash contains an almost complete list of trace elements that the plant needs, in addition, a solution containing iodine and boric acid is a good fungicide against pests and fungi. The working solution is prepared as follows: 1 kg of ash is diluted in 7 liters of boiling water, allowed to brew for a day; then the mixture is topped up with water to a volume of 10 liters and 1 jar of iodine and 10 g of boric acid are added to the solution. Under each bush, 1 liter of such a product is poured. Fertilizer is applied singly.

potassium deficiency

Top dressing with mullein or chicken manure with Mortar or Kemira. We prepare a solution of mullein in its usual concentration (1: 6) and add "Kemira" or "Mulch" at the rate of 1 tbsp. l. funds for 10 liters of mullein solution. The preparations can also be combined with a solution of bird droppings at a concentration of 1:20. Under each bush of determinant tomato varieties, 1.5 liters of solution are added, and under tall ones - 2-2.5 liters.
Serum. A solution of whey and iodine is used for foliar feeding and is carried out approximately once a week. In order to prepare a solution, combine 1 liter of serum and 20 drops of iodine, and then dilute the mixture with 20 liters of water. Spray the vegetative part in dry and calm weather, in the morning or in the evening.
Boric water. Spraying the green mass with boric water will make the fruits sweeter and increase their sugar content. Such treatment is carried out at the flowering stage, but since tomatoes are remontant plants, spraying can also be carried out at the fruiting stage. A solution of boric water is prepared at the rate of 1 g of acid per 1 liter of water.

Boron deficiency

Yeast. To feed tomatoes, live yeast is combined with nettle infusion and wood ash. The solution can also be used during the flowering period, but it is especially useful during the formation of the ovary and fruiting, since yeast is a fruit formation stimulator.

Important! It is recommended to use yeast top dressing only in areas with severe soil depletion, since yeast stimulates the activity of bacteria, as a result of which a lot of nitrogen is released. Recall that an excess of nitrogen harms no less than its deficiency, especially during the period of fruit filling.

Purchased drugs

- a preparation containing many natural phosphates, which are found in water-soluble compounds and are perfectly absorbed by plants. During the period of fruit formation, the plant can lose up to 85% of the accumulated phosphorus, so it is so important to replenish its amount in time.

Phosphorus deficiency.

Auxins(or preparations based on auxins) - stimulate the formation of new fruits, accelerate their ripening and growth, and also increase the presentation. These substances of hormonal origin are mainly used in combination with cytokines. The most used and common auxin-based drug is Kornevin - it is often used to root seedlings or other plants that are transplanted. To improve the yield in the fruiting phase, alpha-naphthylacetic acid (NAA or KANU) is used. The drug is quite active, but if the application rates are observed, it does not accumulate in plant tissues, is non-toxic and is intended for widespread use. Available in the form of a grayish or light yellow powder, soluble in water and organic solvents. Doses and application rates are indicated on the package.

In order for tomato bushes grown on the ground to give large and tasty fruits as a result, they must be fed both during flowering and fruiting. For foliar and root treatments, special feeding formulations are used.

Ground tomatoes have more difficult growing conditions, unlike greenhouse ones. They are sensitive to temperature changes, they need special care, which includes careful watering, top dressing.

What substances do tomatoes need for growth

Plants draw the necessary strength from the soil, but sometimes there are not enough useful substances in the earth. Valuable substances for vegetables are:

Feeding tomatoes after planting in the ground helps to get juicy, healthy, large fruits. Excess fertilizer negatively affects the taste of vegetables.

Signs of a Nutrient Deficiency

You can find out that tomatoes are missing something by the following indicators:

If the foliage on the tomatoes became lethargic, turned yellow, began to fall off, the bushes began to slowly grow and develop, this is the first sign of a lack of nitrogen in the soil. It should be noted that the vegetable crop also reacts to a lack of moisture, low temperature, and poor lighting.
When the stems and leaves turn purple, this is a sign of a lack of phosphorus.
Pale green mass with green streaks - little iron (chlorosis).

For 1000 ml of boiling water 1 tbsp. l. superphosphate.

The solution is insisted for 24 hours, filtered, diluted in 10 liters of water.

When to feed

For tomatoes, high-quality soil and timely top dressing are very important. It is also important not to overfeed the tomatoes with nutrients. There must be a measure in everything. Vegetables love the gradual application of fertilizers, which are necessary in each growing season of the crop.

Weak seedlings after planting (on day 4) in an open area need nitrogen fertilizer. When the tomatoes begin to tie, nitrogen fertilizing should be abandoned. The second time vegetables are fertilized with potassium (during the color period of 1 brush). Dry ash scattered under the bushes is suitable for this.

Top dressing during flowering

When tomatoes begin to bloom, they need potassium and phosphorus, nitrogen fertilizers are excluded. With proper nutrition during flowering, conditions are provided for obtaining a good ovary.

Recipes for dressing tomatoes during the flowering period

When budding and the first flowers appear, it is recommended to carry out yeast fertilizer. Preparation of the composition:

dry yeast - 1 tbsp. l.;
water - 10 liters;
granulated sugar - 3 tbsp. l.

The components are mixed and left to brew for 2 hours. The finished composition is diluted with water at the rate of 1 to 10. The resulting solution is used for root dressing (watering under the root), it is additionally recommended to add ash.

To form a large number of ovaries, foliar fertilizer is used. Spray solution preparation:

Spraying is carried out in the morning and evening hours. The solution should not drain from the foliage. The prepared composition is also an effective remedy against phytophthora.

You can prepare an agrochemical agent from superphosphate:

hot water - 1000 ml;
fertilizer - 2 tbsp. l.

The composition is insisted for 12 hours, the finished mixture is diluted with water at the rate of 1 to 10. Spraying is carried out in the evening.

It is allowed to treat tomatoes with boric acid once during flowering (5 g of boric acid is added to a 10 liter container with water).

Important: regardless of the chosen method of fertilizing, it is necessary to take into account the irrigation regime. Tomatoes need moisture, especially if the weather is hot.

Feeding during fruiting

Harvesting is directly dependent on quality top dressing. In order for the fruits to be tasty and ripen quickly, good fertilizer is necessary.

Cooking:

The prepared solution is used for root dressing: for 1 bush 1.5 liters of fertilizer.

Recipe 2 for root dressing

Cooking:

water - 10 l;
superphosphate - 2 tbsp. l.;
sodium humate - 1 tbsp. l.

The solution is used for root fertilization of crops (per 1 sq. M. 5 l of solution).

Preparation of organic food:

Top dressing of tomatoes in the open field

Seedlings planted in open ground are fed with mineral fertilizers throughout the season. Particular attention is paid to the period of flowering and fruiting.

First fertilization

mullein solution;
superphosphate - 20 g.

Second top dressing

potassium sulfate - 5 g;
nitroammophoska - 50 g.

Calculation for 1 square. m. Complex top dressing is allowed for dry application.

Third top dressing

Composition Stimulus 1.

Stimulates the formation of fruits, accelerates ripening.

How to make seedlings strong and healthy with fertilizer

To get a good crop of tomatoes, you need strong and healthy planting material. Good seedlings are obtained thanks to timely and proper feeding. The first fertilizers are applied during the cultivation of young sprouts. An excess of nitrogen harms plants - the green mass is actively growing, as a result of which the seedlings outgrow and weaken, and the yield decreases. The first feeding is carried out when the first 3-4 leaves appear:

in a 10 liter container with water add 1 tbsp. l. urea.

Next top dressing after 7 days:

per 1000 ml of water, 1 tbsp. l. nitroammophoski (norm for 30 tomato seedlings).

Then fertilizers with nitroammophos are applied every 1.5 weeks until planting material is planted in open ground. Some gardeners, as an alternative to nitroammofoska, use Effecton O or Agricole 3.

Top dressing scheme for tomatoes

It is recommended to feed tomatoes in open ground conditions with mineral and organic fertilizers. A comprehensive fertilizer application scheme begins with digging the soil:

Fertilizing the soil in autumn during digging:

bird droppings (dry) - 300 g;
urea - 15 g;
superphosphate - 15 g;
potassium sulfate - 13 g.

The main fertilizer (nitrogen), 2 weeks after planting the material in the ground:

Second nitrogen stage of fertilization (3 weeks after the first):

urea - 12 g.

Third stage of fertilization (2 weeks after 2):

Foliar top dressing of tomatoes

Summer top dressing for multiple color and ovary formation, both through the sprayer. Plants are fertilized 1 time in 1.5 weeks. Foliar nutrition is necessary to stimulate the growth of fruits, accelerate ripening.

Preparation of foliar nutrient solution:

superphosphate - 1 tsp;
water - 10 l.

Tomato set improvement:

water - 10 l;
a teaspoon of boric acid.

For abundant flowering and reddening of tomatoes, an ash solution is used:

For the prevention of phytophthora:

iodine - 1 vial;
water or whey - 8 l.

Spraying is carried out in the evening or in cloudy weather.

How to water tomatoes for a good harvest

To get a good harvest, gardeners often use folk remedies. With the help of prepared solutions, you can increase the weight of the fruit, improve the quality of taste. For example, iodine root dressings give good results:

10 liter container with water;
iodine - 4 drops.

Complex fertilizer:

The solution is used as a root fertilizer.

To get a rich harvest, you can use the means:

Kemira-Lux - for the growth of bushes;
wagon - dry microelement top dressing;
solute - foliar nutrition;
orton Growth - acceleration of development;
strong man - rooting, stimulation of growth.

Tomatoes need not only fertilizers, but also careful care.

In care, excessive moisture, an excess of fertilizers should be avoided. Tomatoes must be tied to supports, hilled, weeded from weeds, protected from pests, fungi and diseases.

Tomatoes do not need abundant watering, but they do not like drought either. Watering should be done as the soil dries out. In dry times, the soil is well moistened 1-2 times a week, if it rains, the introduction of additional moisture is limited. Gardeners recommend drip or underground moisture. The soil requires loosening at each appearance of a hard crust. It usually forms after rains.

Tomatoes will bear fruit better if they are fed in a timely manner, at least 4 times per season. Tall varieties, after rooting and the beginning of growth, are tied to wooden supports. The height of the supports must be at least one and a half meters. The supports are driven into the ground to a depth of 40 cm. Some varieties of tomatoes are tied to trellises stretched in rows.

During the season, the culture requires hilling (3 times). Weeds should be dealt with throughout the summer. To get a good harvest, it is important to properly form bushes. To do this, leave one powerful stem, all the shoots that appear in the axils of the foliage are removed. So that the plant does not lose color, the stepsons that have grown under the brushes are first removed. When forming a bush, stepchildren are not pulled out, but broken out. Pasynkovanie spend all the time, no matter how many young shoots.

To improve ventilation and warming, the lower foliage on the bushes is completely removed. In August 15-17, the tops of the tomatoes are pinched, and the brushes with color are removed. This is necessary for the rapid ripening of the set fruits.

Extra feeding

Extraordinary nutrition is carried out if the culture gives a signal about the lack of certain elements (by characteristic features). With a lack of nitrogen (slow growth, yellowing of the lower tiers of green mass, pale green foliage), tomatoes are fed with saltpeter or urea. The lack of phosphorus is eliminated with superphosphate fertilizer. If the upper leaves are curled, then the plant lacks potassium. Spend spraying with potassium sulfide. With chlorosis, tomatoes are watered with chelate.

When tomatoes have thin shoots, this signals a lack of calcium. Replenish the lack of an element with fertilizer with saltpeter. Timely assistance to plants helps to eliminate defects and meet the needs of the culture. As a result, a tasty and rich harvest.

How to fertilize in August

For the entire last month of summer, tomatoes are fed to accelerate the ripening of already formed fruits. To do this, in early August, the tops are pinched on tomato bushes (redirecting the plant's forces to the development of fruits). Once every 10 days. The necessary nutrition for tomatoes can be given like this top dressing:

water - 10 l;
potassium monophosphate - 15 g;
potassium magnesia - 10 g.

The prepared solution is favorable for the August harvest.

What to use for tomatoes to be plump

In order for tomato seedlings to be strong and give a good harvest, they need nutrition. Thick stems are able to withstand high yield loads. Having planted seedlings, it must be nourished for a fortress:

After fermentation, a working solution (1 to 10) is prepared from the mixture concentrate.

Another recipe for one nutritional composition in order for tomatoes to become plump:

granulated sugar - 125 g;
fresh yeast - 100 g;
warm water - 3000 ml.

The solution is left to ferment in heat for 24 hours. The composition should be stirred periodically. A working solution is prepared from the finished concentrate: 250 ml of the yeast composition is poured into a 10 liter container. Gardeners also recommend to thicken the stems, at the beginning of the formation of bushes, fertilize tomatoes with calcium nitrate (30 g of the product per bucket of water).

Tomato is one of the most beloved vegetables in our country. However, few people know that it is equated with lemon because of the large amount of nutrients. That is why many novice gardeners try various means to feed and preserve the ovaries. Such fertilizers fill the future tomatoes with the necessary trace elements and give a chance to get an excellent harvest.

Particular attention is paid to planting seedlings in open ground, a greenhouse and the appearance of the first ovaries. And in order to get a good harvest, they use folk remedies for the ovary of tomatoes, which we will discuss later in the article.

Reducing the ovaries of tomatoes in the greenhouse: causes and effects

If you do not adhere to the temperature regime, then the flowers of tomatoes may fall off without waiting for pollination. Acceptable daytime temperatures range from +23°C to +29°C, and nighttime temperatures should be between +13°C and 21°C.

The maximum temperature at which tomatoes feel normal is 36 ° C. If it rises to 40 ° C, then it is safe to say that there will be no flowers and ovaries. And every night the temperature should drop below + 20 ° C. If you neglect this rule, then the tomato crop may fall. And in this case, even the best folk remedies for the ovary of tomatoes in the greenhouse will not help.

Humidity in the greenhouse should fluctuate between 40-70%. To achieve the required indicator, you should lightly spray the tomatoes every morning. But it is very difficult to get rid of excess moisture. Therefore, experienced gardeners mulch the bushes, and to maintain moisture, they dig plastic bottles with holes or no bottom into the soil.

Reasons for reducing the ovaries of tomatoes in the open field

Gardeners recommend carefully studying the methods of planting and the characteristics of varieties, since non-compliance with the norms can lead to a complete loss of yield or make it extremely low. The absence of ovaries may be due to such reasons as:

Lack of sunlight due to too close trees or other plants.
Excess nitrogen, due to a large amount, leads to a change in inflorescences.
Lack of minerals such as phosphorus and potassium.
Lack of strength in tomatoes for the formation of ovaries. Especially in the case of growing large and multiple varieties.
Diseases affecting the plant.

A few secrets for a better tomato ovary

To avoid a decrease in yield, they resort to folk remedies. But before you spray the tomatoes for the ovary with folk remedies, you need to follow a few simple recommendations:

Seedlings in the greenhouse should be planted from east to west. This will allow the tomatoes to receive the same amount of sunlight in the morning and in the afternoon.
Two-time hilling will help strengthen the root system. For the first time it is carried out during the appearance of small growths on the stem. The second time they spud after the shoot has changed color to dark blue.
Mulching will protect against excess moisture, expose the roots, and also slow down the growth of weeds.
Removing unnecessary shoots (stepping) will help tomatoes not to waste energy on growing green shoots, but to direct all their energy to a rich harvest.

How are tomatoes fed?

Many novice gardeners are wondering how to feed tomatoes for fruit set. As a rule, they are advised to go to a specialized store and buy the necessary tool for this. But you can also make an amazing mixture from familiar products and increase the yield of tomatoes.

So, experts say that there are only two ways to peel tomatoes:

Most often they are watered with a mixture of nutrients under the root. Since this is the easiest and most convenient type of feeding, although not the most effective. For the most part, the fertilizer soaks up the soil around the tomatoes without even touching their roots.
Less common is the foliar method. With the help of a special sprayer, the fertilizer is sprayed not only under the root, but also settles on the leaves and stem. Thus, by increasing the surface of exposure, tomatoes absorb nutrients faster and gain strength for further development.

It is worth noting that before watering it is necessary to defend chlorinated water, since this substance is detrimental to any plant. But it is most useful to use rainwater, which has all the necessary elements.

But first, it is necessary to determine which trace elements they lack. Experts identify the following substances, which each tomato especially needs. These are potassium, nitrogen and phosphorus. Dozens of recipes have been invented that restore the balance of substances and increase yields. So how to feed tomatoes for fruit set?

One of the most popular remedies is bird droppings. It contains a huge amount of nitrogen and contributes to the rapid growth and development of green mass. It is necessary to take 10 kg of bird droppings and pour 5 liters of water, then let it brew for 3 days. You will get a very concentrated mixture, so 1 liter of this fertilizer is diluted with 10 liters of settled water.

Tomato seedlings, especially before planting in open ground, need phosphorus and potassium. To provide the plant with the necessary substances, ash (wood or straw) is used. The fertilizer recipe is simple: you should take 15 g of ash and pour 2 liters of hot water. Let the mixture brew for a day, and then filter and use as directed.

To make nitrogen easier to absorb, it is necessary to provide the plant with an optimal amount of potassium. To do this, pour three banana peels with 3 liters of boiled water. After three days, the skins will give up all the potassium and other useful substances. Thus, a unique folk remedy for the ovary of tomatoes is obtained.

Gardeners recommend making complex fertilizer from eggshells, which are rich in many trace elements. It is able to increase the growth and development of tomatoes. To do this, you need to take the shell of three eggs and pour three liters of hot water. This folk remedy for the ovary of tomatoes should be infused for 72 hours. The finished fertilizer will exude a hydrogen sulfide smell.

Folk remedies for foliar fertilizer

There is no better way than to spray tomatoes for the ovary with folk remedies. However, it should be remembered that the spray mixture should consist of 1% fertilizer and the rest water. Usually they begin to feed a week after planting seedlings in open ground. Here are some popular recipes:

10 drops of iodine are mixed with 1 liter of curdled milk and a bucket of water.
Add 2 liters of whey, half a glass of sugar and 16 drops of iodine to a bucket of water.
Birch fungus is dissolved to the extent that the water becomes dark in color.

The use of boric acid for the ovary of tomatoes

One of the effective means is the treatment of tomatoes with boric acid for the ovary. This substance is necessary for every tomato, as it is involved in the transport of calcium to all parts of the plant, accelerates the growth of shoots, helps to preserve flowers and form fruits.

Some gardeners add boric acid to seedling holes. However, it should be remembered that only after a day it will be possible to plant tomatoes in this soil.

Spraying is the most popular fertilization method. Therefore, there are several recipes for the ovary:

dilute half a packet of boric acid (5 g) in 5 liters of water;
it is necessary to mix 5 g of boric acid, copper sulfate and urea and dissolve in 10 liters of water.

Gardeners note that boric acid dissolves best in hot water.

Folk remedies for greenhouse tomatoes

Many fertilizers are used both for seedlings in open ground and for greenhouses. However, there are still folk remedies for the ovary of tomatoes in the greenhouse, which were not mentioned earlier:

Coffee beans are the best source of nutrients for greenhouse plants. When ground, they perfectly loosen the soil and open access to oxygen for the root system.
Onion peel fills the seedlings with useful trace elements, disinfects and protects the leaves from pests. It is necessary to take 40 g of husk, pour 10 liters of water and leave for 96 hours.
Strengthens the immune system and accelerates the growth of seedlings yeast mixture for the ovary of tomatoes. It is able to change the structure of the soil and speed up the metabolism in it. To prepare the fertilizer, use 2 g of dry or 100 g of fresh yeast and pour 2 liters of warm water.

Favorable time for feeding tomatoes

They begin to feed the tomatoes in the early morning or evening on a clear sunny day. Fertilizers for the root system should not fall on the leaves, as excess moisture will not be able to be absorbed and sunburn will appear on the leaf.

In cloudy weather, tomatoes are sprayed with folk remedies for the ovary at any time of the day. The main condition is that before nightfall, the moisture from the leaves should evaporate.

Before spraying tomatoes for the ovary with folk remedies, it is necessary to study all the recipes in detail. And only then proceed to practical application. Thus, each gardener increases the chances of getting a rich harvest with tasty and healthy fruits.

Everyone knows that tomatoes grown in their own garden are much tastier than those sold in stores and markets. In order for the harvest to please with its abundance, and the tomatoes to be large, juicy and tasty, the plants need to be provided with proper care and conditions for good development. For good growth, tomatoes need nutrition, because the more abundant the crop, the more nutrients it takes from the soil.

That is why plants need periodic feeding. Tomatoes do not like an overabundance of fertilizers. An imbalance of certain substances in the soil can cause stunting, disease, or dropping of ovaries in the plant.

Fertilizing tomatoes with yeast

Ordinary nutritional yeast can act as a top dressing for tomatoes. They contain many substances that these plants need. You can fertilize tomatoes 2 times a season. To prepare the product, take 1 sachet of instant yeast, mix with 2 tbsp. l. sugar, warm water (a small amount), after insisting for a couple of hours and mixed with 1 bucket of water. This composition is used when watering plants as follows: 0.5 liters of solution will be needed for 1 watering can of water. The effect will be visible after 3 days: the tomatoes grow rapidly, and the leaves and stems become stronger. raw yeast (pre-dilute with water). Pour everything with warm water, close the lid and put in a large saucepan (the solution will pour out of the container during fermentation). The mixture should ferment for at least 3 days. After it, you need to strain and water the tomatoes in the following proportion: for 10 liters of water, 1 liter of solution.

Top dressing of tomatoes in the open field during flowering

Many novice gardeners do not know exactly what products to use to fertilize tomatoes during flowering. Caring for seedlings in the open field requires a lot of time and effort.

Top dressing is used in cases where the seedlings were planted in, which was not fertilized in advance. Usually, the seedlings develop for about 2 months and during all this time the plants need food. Particular attention should be paid to the period of formation of the ovary of flowers and the flowering itself.

At this time, you can use both simple mineral fertilizers, such as urea, superphosphate, ammonium nitrate, and complex ones designed specifically for tomato seedlings - diammophos, nitroammophoska, kemira, etc. It is convenient to use special nutrient boxes and pots that are filled with a substrate, soil mixture with essential organic matter. You can use a solution of mullein or chicken droppings as fertilizers, and during flowering, it is useful to sprinkle the inflorescences themselves with a boric solution. Such an element as phosphorus important at all stages of development and formation of tomatoes.

It is responsible for the proper development of the roots and helps to activate the processes of fruit set. The first top dressing should be done 21 days after transplanting.

To do this, you need to make a solution: for 10 liters of water, 0.5 kg of liquid mullein and 1 tbsp. l. nitrophoska. The following dressing is done during the blooming of brushes with flowers. To do this, it is better to use ready-made fertilizers for tomatoes during flowering, for example, such as Senor tomato - 1 tbsp. l. this drug must be diluted in 10 liters of water. You can use mineral fertilizer Tomato Master.

Top dressing of tomatoes in the greenhouse during flowering

Tomatoes that are grown in greenhouse conditions, as well as those that grow in open ground, need regular top dressing. You can fertilize such seedlings from the very beginning of development, immediately after the first leaves have formed.

It is best to choose a top dressing for these purposes, which includes many different nutrients. During the flowering of tomatoes, you need to carefully use fertilizers that contain nitrogen. Dose the use of biohumus, granulated compost and other organic fertilizers. They can certainly be used, but the effect will be weak.

Tomato care: pinching

In order for tomatoes to give large fruits and accelerate growth, it is necessary to carry out the formation of the plants themselves. It consists in getting rid of the side trunks that grow between the leaves, they are also called stepchildren. The very first stepchildren are made 3 weeks after planting the seedlings.

During this time, the tomatoes reach a size of 7 cm. After this procedure, you need to carry out this procedure regularly. It is necessary to break out the branches with the thumb and forefinger.

They cannot be torn out, otherwise wounds are formed that heal for a long time, fungal infections can penetrate into the plant through them. If the pinching was done with some delay, then the shoots must be cut with a sharp knife, not forgetting to leave 1 cm near the trunk.

What can happen if you do not feed tomatoes?

If you refuse to feed, the leaves of the plant will suffer first. They will lose their shape, begin to curl even at the very beginning of growth, and may fall off. This is often due to an excess of nitrogen in the soil, and its deficiency is manifested in the yellowing of the foliage, its stunting and falling off. The most important thing is not to confuse these symptoms with exposure to low temperatures and lack of moisture. You also need to feed tomatoes in greenhouse conditions with phosphorus, because due to its lack, the plant can turn purple. But if the leaves grow normally, then the deficiency of the substance is considered the norm. Less common is a lack of calcium. It is formed more often when cultivating a crop in greenhouse conditions and manifests itself in the form of top rot on the bushes themselves. Feeding seedlings is necessary in a small amount, but often. It is best to use complex fertilizers.

Read also: We list the most significant fertilizers for this crop:

potassium; phosphorus; nitrogen.

Phosphorus is of great importance for the formation of the root system and fruit set. If plants do not get enough of this substance, then tomatoes do not absorb nitrogen and other necessary nutrients.

The symptoms of phosphorus starvation in tomatoes are the appearance of red-violet spots on the underside of the leaves, as well as the twisting of the leaves along the main vein, and fruit ripening also slows down. This mineral contributes to the formation of stems, as well as the absorption and processing of carbon dioxide.

In case of a lack of potassium, the lower leaves accumulate ammonia nitrogen, as a result of which they first wither, and later die. In the photo you see how the result of potassium starvation of tomatoes appears on the leaves: Let's take a closer look at what and how to feed tomatoes in a greenhouse.

When and what kind of feeding is carried out

The very first top dressing can be carried out in the process of planting tomato seedlings in a greenhouse. Compost or humus is placed in pre-prepared holes and ash is added.

Compost, like humus, contains a lot of minerals, and the ash has a high content of a variety of micro and macro elements that are so necessary for a tomato for normal development, growth, flowering, setting and formation of fruits. The question is how to feed tomatoes after planting in a greenhouse , causes "hot" discussions among gardeners. Part of the "gardening" community is of the opinion that the question of how to feed tomatoes in a greenhouse immediately after planting is not worth it at all. Such gardeners believe that the first top dressing of greenhouse tomatoes should be carried out no earlier than two weeks after transplanting plants to a permanent place. Other gardeners are of the opinion that for “injured” seedling transplants, tomatoes in a greenhouse should be fed earlier, preferably immediately after transplantation, all the better.

For the first feeding, these gardeners recommend using organic fertilizers, or the so-called "green tea". This fertilizer is easy to make with your own hands. For its preparation, a variety of herbs are taken (various weeds, such as nettle, plantain and others), to which a bucket of liquid mullein and a glass of wood ash are added.

For infusion, 4-5 kg of finely chopped grass are taken for 50 liters of water, mullein and ash are added, mixed and left for several days to infuse. Then bring the volume of the solution to 100 liters. About 2 liters of ready-made infusion are poured under each bush.

Important: mineral dressings carried out at this time by many gardeners have a one-sided effect on plants. Some of them stimulate the active growth of green mass, others enhance flowering. If there are no organic fertilizers, it is better to fertilize tomatoes with any complex mineral fertilizer. So, if you think that the soil in your greenhouse is well fertilized, then you can not do fertilizing after transplanting tomato seedlings. Then, an approximate dressing plan will be as follows:

The first feeding will be carried out approximately in 15-20 days after plant transplantation. Mineral fertilizers are used for it, diluting them in 10 liters of water:
25 g nitrogen; 15 g potassium.

Under each plant spend 1 liter of the prepared solution.

The next top dressing is carried out at a time when the tomatoes begin to bloom en masse (see Forming a tomato bush in a greenhouse - how to do it right), since it is necessary to feed the tomatoes in the greenhouse for normal fruit set in the future. In 10 liters of water, dilute 1 tbsp. a spoonful of potassium sulfate, 0.5 l of bird droppings and the same amount of liquid mullein. Each plant should receive 1-1.5 liters of the prepared solution.

If there is little or no organic fertilizer, then top dressing can be carried out by dissolving 1 tbsp. a spoonful of nitrophoska in 1 bucket of water. 1 liter of working solution is spent on each plant. During the flowering of tomatoes, in order to prevent blossom-end rot of tomatoes, it is necessary to spray the plants with an aqueous solution of calcium nitrate. To prepare it 1st. a spoonful of fertilizer is diluted in 10 liters of water.

During the formation of the ovaries, it is necessary to feed the tomatoes with a solution of 2 liters of wood ash and 10 g of boric acid, diluted in 10 liters of hot water. The prepared solution must be insisted for a day so that all the elements are completely dissolved. Such a mixture contains a large number of micro and macro elements that will help the crop to form more quickly. Each plant is watered with 1 liter of the prepared working solution. For this root dressing, 2 tbsp are dissolved in 10 liters of water. spoons of superphosphate and 1 tbsp. a spoonful of liquid sodium humate.

In any case, there is no clear instruction on when, how often and with what fertilizers to fertilize greenhouse tomatoes. Each gardener, knowing what vegetables were grown in the previous season and what fertilizers were used, follows an approximate feeding scheme, “adjusting” to the characteristics of the plants, the vagaries of the weather and relying on their experience.

Foliar top dressing

In addition to the usual root top dressing of tomatoes, it is also useful to use foliar top dressing - spraying the stems and leaves of tomatoes. A feature of foliar dressings is that they are able to convey to the plant the substances it needs, which are lacking in the soil.

This is due to the fact that the leaves, unlike the roots, absorb only the elements that are missing for the plant. If the tomatoes lack some specific elements, how to feed the tomatoes in the greenhouse is decided by foliar feeding the missing elements. Spraying plants with a solution containing deficient substances very quickly gives positive results, manifesting itself literally in a few hours.

If you make the same elements through root dressing, then the result can be seen only after a week or two. During flowering, thinking about how to feed tomatoes in a greenhouse, you can perform foliar top dressing with a solution of boric acid and wood ash extract.Advice: to prepare an extract from wood ash, take two glasses of ash and pour 2-3 liters of hot water.

Infuse for a couple of days, after which the precipitate is filtered. The resulting solution is adjusted with water to a volume of 10 liters, after which the plants are sprayed.

How to fill the deficiency of nutrients

Tomatoes very clearly signal with their appearance exactly what elements they lack (see more Diseases of tomatoes in a greenhouse: their varieties and how to deal with them). External signs of mineral deficiency

with a lack of phosphorus, the stem, the lower surface of the leaves and the veins on them become purple. If you spray the plants with a weakly concentrated solution of superphosphate, then after a day the purple color disappears. Calcium deficiency leads to the leaf plate twisting inward and the disease of the tomato fruits with blossom end rot. In this case, spraying the plants with a solution of calcium nitrate will help. If the plants do not have enough nitrogen, the plant becomes light green or yellowish, lags behind in growth and becomes very thin. Spraying "herbal tea" or a very weak solution of urea will help to cope with nitrogen deficiency.

You may get the impression that feeding greenhouse tomatoes is too troublesome and unnecessary. It is enough just to fertilize the soil during spring and autumn digging, and then plant the tomato in the greenhouse.

Indeed, if the soil is not depleted and the correct crop rotation is practiced, the harvest can be obtained. But if you carefully look after the plants and promptly respond to their needs, constantly take care of them, you can get a much more abundant and high-quality tomato crop in the greenhouse. task.

Growing tomatoes in a greenhouse

A plentiful harvest is expected from tomatoes - the norm from one bush is at least 3 kilograms, under favorable conditions, 10 or more can be removed. Productivity depends primarily on the variety, and then on the method of cultivation and care.

But even the most prolific variety can be spoiled, yet compliance with agrotechnical rules plays a very important role. Growing tomatoes in a greenhouse has its own subtleties; greenhouse tomatoes require completely different care than ground ones. If you want to try this method of growing tomatoes, or you already have experience, but you are looking for useful recommendations, then this article is for you.

What varieties of tomatoes are suitable for a greenhouse

Tomatoes are divided into determinant and indeterminate varieties. The first ones are compact, form up to 5-6 inflorescences, and after the central stem stops growing, the last flower brush forms on it.

Determinant varieties are considered earlier, they are harvested in a short time. Indeterminate varieties they do not stop growing, they grow and bloom all the time, respectively, and the harvest as a whole gives more, but the fruits ripen later and not evenly. Both are suitable for growing in greenhouses. Also, when choosing a variety, one should pay attention to its other characteristics , such as disease resistance, yield, how well the fruits store, whether they are prone to cracking.

Planting time for tomato seedlings in the greenhouse

Planting seedlings in a greenhouse begins much earlier than planting tomatoes in open ground. But how much earlier - it's up to you, and each case must be considered individually.

Of great importance is what region you are in, what the weather is like and, of course, what kind of greenhouse you have. If this is a serious building with the ability to keep warm inside - this is one thing, but if you call the beds covered with a film a greenhouse, then this is completely different.

In the first case, seedlings can be planted almost all year round, technically it is possible all 12 months, but in deep winter the seedlings grow very poorly and slowly, so it is reasonable to wait until February or March. Seedlings begin to be planted in a film greenhouse in April or even early May.

Before planting check the night temperature in the greenhouse, it should not fall below 15-17 degrees the soil must be warm. The ideal temperature for a tomato is 22-26 degrees, under such conditions, planting should be most of the day.

Preparing the soil

It is necessary to prepare the soil for tomatoes, and it does not matter in which greenhouse you will grow them. The land begins to be prepared in the fall, organic fertilizers are applied to it, for example, compost and mullein, so that by spring they will rot and saturate the soil with nutrients, in particular nitrogen, necessary for active growth.

Phytolamps and result: flowering of tomatoes

The earth is deeply dug up, loosened, weeds, roots are removed and fertilizers are applied, two buckets per 1 m2. From above, the soil can be mulched with peat or sawdust, this will partially prevent the appearance of weeds in the spring. It is good to add wood ash to the soil in the fall.

It is crushed into dust and mixed with soil, 1-1.5 cups of ash is required per 1 m2. This will be enough to grow tomatoes in a mobile film greenhouse. If the greenhouse is stationary, then the soil is treated more carefully.

It is extremely important not only to fertilize it, but also to disinfect it, since most often greenhouse crops, including tomatoes, die from various diseases - fungi, viruses, bacteria, which multiply at lightning speed in a warm and humid environment. Do not reuse greenhouse soil if you are in doubt about the quality of the soil, and you should not use it for greenhouse cultivation either.

With long-term cultivation of tomatoes in a greenhouse, every year the top layer of soil is replaced, for this, 10-15 cm of soil is removed, it is thrown out, since it is there that the concentration of pest diseases is highest. You can send this soil for processing, mix it with bleach and leave it for a year or two.

Also, do not forget that after tomatoes the land cannot be used for growing other crops. Any soil must be treated with fungicides - antifungal drugs, and it is advisable to act on it with high temperature - ignite in the oven or pour boiling water - this is how they prepare the land for seedlings. Of course, it is quite difficult to prepare the soil for a large greenhouse in this way, so vegetable growers use chemical or bio means.

For example, the earth can be disinfected by spilling it with Bordeaux liquid, potassium permanganate or a solution of copper sulfate. Even for large and stationary greenhouses, you can use the gas disinfection method. For this, special sulfur bombs are needed, they are set on fire and in the process of combustion gases begin to be produced that penetrate into the soil and into all nooks and crannies of the greenhouse.

The gas, reacting with moisture, forms sulfurous and sulfuric acids, which destroy fungal, viral, bacterial infections, snails, slugs, ticks and other pests. In addition to soil they also process the greenhouse itself. If the gas method is not suitable, then bleach can be used.

400-500 grams of bleach is dissolved in a bucket of water, infused for several hours, the contents are stratified and the liquid is drained. It is filtered and used for spraying, whitewashing all structures in the greenhouse, as well as walls and roofs. In spring, fertilizers are also added to the soil before planting seedlings.

It can be rotted manure or compost - one bucket per meter. To this volume of organics add 1 tablespoon of urea and potassium sulfate. You can use any other complex mineral fertilizer at the rate of 1.5 tablespoons per m2.

Planting seedlings in a greenhouse

Time must pass between the end of the soil preparation and the planting of seedlings. The earth must first be well watered and allowed to warm up; it is impossible to plant tomatoes in wet and cold soil. The beds are arranged so that adult bushes do not interfere with each other.

Too close planting will negatively affect the growth of bushes and the ripening of fruits. Compact varieties are planted at intervals of 35-45 cm, large ones - 55-65 cm, the distance between rows is 60-70 cm and 90-100 cm, respectively. As for open ground, holes for planting tomatoes are dug in advance and poured with plenty of water.

For example, if you formed holes today, then you need to plant tomatoes tomorrow morning or evening. True, in the greenhouse this event can be scheduled for the day, the active sun will not be able to damage the tender seedlings through the shelter. The seedlings are carefully removed from the container or planted directly in peat pots, the soil around is slightly compacted and mulched with peat.

You can immediately put supports for garter tomatoes. A few days after planting, the tomatoes are not watered. They may become lethargic, but on the second day they should begin to move away.

Watering is carried out when the seedlings come to their senses, it is because of this pause before planting that the wells are abundantly filled with water so that the soil is moist and in deep layers.

Caring for tomatoes in a greenhouse

Top dressing is necessary for all greenhouse crops, and especially for tomatoes. Tomatoes in the greenhouse are fed 4-5 times, this is the only way to get a good harvest. The first time tomatoes are fertilized two weeks after planting.

At this time, nitrogen-containing substances such as diluted manure are introduced, or urea can be used. The manure is dissolved in water and the beds are spilled in half a bucket under the bush, urea is added at the rate of 1 tablespoon per 10 liters, two liters of solution are poured under the bush. The second time the tomatoes are fertilized 7-10 days after the first feeding.

You can repeat the procedure or choose something else, such as chicken manure solution. In its pure form, it is not used, as it is very caustic. The third top dressing occurs at the beginning of the flowering of tomatoes.

At this point, the plants no longer need nitrogen, but potassium in order to set fruits, and it is contained in wood ash. A glass of ash per 1 m2 is enough.

After fertilizing, the tomatoes must be watered. The fourth time the tomatoes are fed in the middle of flowering and sodium humate is used at a dosage of 1 tablespoon per 10 liters - this is enough for 2 m2. This top dressing option can be replaced by the third, if there is no possibility or desire to make wood ash. The fifth and last top dressing is needed to speed up the ripening of tomatoes.

When the fruits have already reached their maximum size, but are in no hurry to blush, they can be treated with superphosphate. To prepare a solution for spraying, take 2 tablespoons of superphosphate per 2 liters of water, insist for a day and add another 8 liters of water. It is necessary to spray tomatoes in the evening so that the drops do not heat up and burn the leaves, but not at night, so that the tomatoes do not spend the night wet, this can lead to hypothermia and the development of diseases.

Removal of stepchildren

10-15 days after planting the seedlings, you need to start making sure that stepchildren do not grow on the bushes. If you notice their appearance, then delete immediately. It is believed that stepchildren up to 2.5 cm can be removed without harm to the plant, the removal of larger ones injures the tomato.

Watering

In the greenhouse, tomatoes need moderate watering, as the humidity there is always kept at a high level. Abundant watering will lead to decay, the formation of rot. The first time tomatoes are watered 5-10 days after planting, they are guided by the state of the soil and the type of plants.

Before the appearance of the ovaries, the tomatoes are watered so that the soil does not dry out, no more. At this time, preference is given to rare, but plentiful watering. After the formation of the ovary, watering is gradually increased and then watered abundantly, but as needed.

The regularity of watering is strongly influenced by the humidity in the greenhouse, in one the indicators drop significantly 2-3 days after watering, in the other the high humidity is constant. In the greenhouse, tomatoes are also watered only in the morning or in the evening, water is poured under the bush, leaves, flowers and stems are not wet.

Pollination

During flowering and the appearance of the ovary, the humidity in the greenhouse is reduced, this is necessary for better pollination. Tomatoes self-pollinate, but they can be helped - just lightly shake the bushes, do this before lunch for several days in a row.

Harvest

Tomato fruits have 4 stages of maturity, they can be: green, milky, brown and ripe. Tomatoes should not be left overripe on the bush, this significantly reduces their taste. It is better to harvest this culture when it is almost ripe, brown, firstly, the fruits will ripen perfectly themselves, and secondly, it will speed up the ripening of the next, green or milk tomatoes.
