Top dressing of tomatoes during the flowering of the first brush. How to feed tomatoes during flowering

20.06.2020

Feeding tomatoes. During the growing season, it is necessary to do three to four root dressings.

Happy harvest!

I really like the positive reaction of my tomatoes to the "green manure". How do I prepare it? Very simple. There are a lot of recipes for such a "green manure". Its basis is mowed green weed grass.

What fertilizers do tomatoes need

Once a month, Anna advises doing root dressing with organic fertilizer. She calls it "Kurdyumov's compote", and I have this "green manure". The process of its preparation is described in detail below.

Bifungin (birch mushroom (chaga) - sold in a pharmacy - dilute in water by eye until dark.

So, two weeks have passed since you planted tomato seedlings in a greenhouse or open ground. It's time to feed the plants. Top dressing of tomatoes open ground or greenhouse - is there a difference? What types of top dressings are there? Last years gardeners (those I know) prefer organic, trying to use less mineral fertilizers, but do not completely abandon them. Home-made cheap, but very effective "green manure" is very popular. But about him, a little lower.

Yeast. They are the best plant growth stimulator.
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

Part of the "gardening" community is of the opinion that the question of how to feed the tomatoes in the greenhouse immediately after planting is not worth it at all. Such gardeners believe that the first feeding of greenhouse tomatoes should be carried out no earlier than two weeks after transplanting plants to a permanent place.

First root dressing (20 days after planting seedlings). For 10 liters of water, 1 tablespoon of nitrophoska and 1 tablespoon of Ideal fertilizer. Based on 1 liter per plant.

When and what kind of feeding is carried out

I have an old metal 200 liter barrel. But it is not advised to use a metal barrel for the preparation of this fertilizer, apparently, the process of metal oxidation adversely affects the quality. I don't have a plastic barrel. You know, there are almost no hopeless situations. I bought huge 300-liter plastic bags. I put one bag into another (for strength), placed them inside the barrel. Filled 1/3 with water to straighten them. The polyethylene warmed up a little by the sun, became elastic, stretched, the bags were tightly dressed outside on the edge of the barrel. I got a metal barrel with a plastic liner.

Every 2 weeks, it does not hurt to feed the tomatoes with an ash solution - pour 1 glass of ash with a bucket of water, let it brew for several hours. The ash solution contains potassium, calcium, phosphorus, many different trace elements necessary for the development of plants.

One teaspoon boric acid, blue vitriol, magnesia, (boric acid and magnesia are sold in a pharmacy) + manganese on the tip of a knife + coarsely grated laundry soap or 3 tablespoons of liquid soap dissolved in 10 liters of water.

There are two types of dressings. Root and foliar.

Recipe for the preparation of yeast fertilizer: 20 grams of yeast is diluted in 10 liters of water, left for 24 hours, plants are fertilized with the resulting solution. "Rostmoment" is a ready-made fertilizer, which is produced on the basis of yeast. It is also suitable for planting tomatoes. This tool is the best biostimulator of growth and further development plants. Using this fertilizer, you can be sure of its quality. "Rostmoment" is suitable for fertilizing tomatoes that grow in pots.

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.

. Each plant should receive 1-1.5 liters of the prepared solution.

Other gardeners are of the opinion that for seedlings “injured” by transplanting tomatoes in a greenhouse, the sooner you feed them, preferably immediately after transplantation, the better. For the first feeding, these gardeners recommend using organic fertilizers, or the so-called "green tea".

After the tomato seedlings were grown with their own hands or bought and planted in a greenhouse, many gardeners have a question: how to feed the tomatoes after planting in the greenhouse?

Second root dressing (10 days after the first). For 10 liters of water, 1 tablespoon of superphosphate, 1 teaspoon of potassium nitrate or potassium sulfate. Based on 5 liters per 1 m2. Useful: So, I already had a little water in the barrel, I add mowed grass there. Experienced gardeners advise filling the barrel with cut nettles. But I didn’t have so many nettles, so I sketched an almost full (2/3) barrel of various weeds, nettles were there too.

Very important point: if you are doing foliar feeding or root feeding, then this should be done in the morning or in the evening. Why is that? If we are talking about foliar, then the nutrient solution should be on the surface of the leaves for as long as possible so that it can be absorbed. And in bright sunshine, spraying the leaves can cause a burn. This is first. And secondly, the sun will quickly dry up the droplets of the nutrient solution, it will not have time to be completely absorbed by the leaves. When foliar, you should make sure that the solution gets not only from the top of the sheet, but also from the bottom too.
Trichopolum (10 tablets) + 1 small vial of brilliant green + 10 liters of water.
Root top dressing is used by most gardeners. It nourishes the plants through the root system, that is, it is watering with a nutritious mineral or organic solution under the root.

Ash is an excellent source of potassium and phosphorus, magnesium, sulfur, zinc and other trace elements. Ash is added before planting seedlings in each hole. To do this, take 3 tablespoons of ash and mix it with the soil. To enrich the soil, 3 cups of ash per 1 square meter are required.

Calcium deficiency leads to twisting of the leaf plate inward and disease of the tomato fruit with blossom end rot. In this case, spraying the plants with a solution of calcium nitrate will help.
"Herbal tea" To answer this question, you should remember why you need to feed tomatoes in a greenhouse. The main goal of applying any fertilizer is to get a rich crop of high quality tomatoes with good taste. In order for each tomato bush to please you with a large number of fruits of excellent taste, it is necessary to provide the plants with a complete and balanced diet.

Third root dressing (12 days after the second). For 10 liters of water, 1 liter of mushy mullein or chicken manure or 1 tablespoon of sodium humate. Based on 6-8 liters per 1 m2.

Feeding cucumbers in a greenhouse or open ground with fertilizers - mineral and organic

From above I threw about 1 kg of wood ash, half a bucket of chicken manure, added 2 liters of milk "store" whey (natural, they say, 1 liter is enough), a pack of baker's yeast (100 g). I added water almost to the top. Under the root, you also need to water the plants with a mineral or organic solution early in the morning or in the evening. I prefer evening watering, and my dacha neighbor waters his cucumbers, tomatoes in a greenhouse or open field only early in the morning. The reasons also seem to be clear: water or a nutrient solution that has fallen on the leaves during the day can cause sunburn of the foliage. You should not force the plant to spend energy restoring or healing wounds. 1 teaspoon of boric acid, copper sulfate, urea (kabamide) per 10 liters of water.

Many people know about foliar, but they use it less often, but in vain.
A key role in the growth of fruits is played by fertilizing the soil when planting tomatoes.

In the event that the plants lack nitrogen, the plant becomes light green or yellowish, stunted and become very thin. Spraying with “herbal tea” or a very weak solution of urea will help to cope with nitrogen deficiency.

Foliar top dressing

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. For each plant, 1 liter of working solution is consumed.

This fertilizer is easy to prepare 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.

Tomatoes, however, like other representatives of the nightshade family, are responsive both to fertilizing the soil and to various foliar top dressings. However, it does not follow from this that top dressing of greenhouse tomatoes involves the introduction of a huge amount of fertilizer into the ground and constant spraying of plants. Fertilization needs to be done wisely and carefully, and it is better to give the plants less fertilizer than to overfeed them. The third and fourth feeding with an interval of 8-10 days is done with a solution of the Signor Tomato fertilizer (1 tablespoon per 10 liters of water) or pour 1 full teaspoon of dry Fertilizer around the plant before watering.

In some Russian regions, the most optimal conditions for growing tomatoes are greenhouses. There they grow better and delight with large yields. However, this is a very laborious task, because if appropriate measures are not taken in time, this culture is much more likely to be affected by diseases.

How to fill the deficiency of nutrients

This recipe was taken long ago from the book "Smart Farming" by Yu.I. Sweetie. He calls this solution an infusion of microbial organisms. The author recommends adding mash instead of yeast - 3 liters of non-chlorinated water, 150 g of sugar, leave for 2-3 days.

The question is usually asked, how often should tomatoes be fertilized with mineral or organic fertilizers? The short answer is not very often. And, to be more precise, I spend them, both root and foliar, in 10-15 days. That is, about 2-3 times a month. I alternate them. Once - foliar, next time - I feed my tomatoes under the root.

Weak solution of manganese.
Foliar - this is when we apply the same nutrient solution directly on top of the leaves, branches of plants. This type of top dressing of tomatoes with mineral or organic fertilizers has several advantages. First, it allows you to save fertilizer. Because when we apply them under plants, a significant part of the nutrients is washed out with irrigation, during rain, not all nutrients get to the plant.
Chicken manure is a fairly valuable fertilizer. Its chemical composition is ahead of manure, and nutrients are contained in quite mild form. Feeding tomatoes with chicken manure has a prolonged effect, even after two or three years after fertilization, the soil remains saturated and has a positive effect on plants. Feeding from bird droppings is prepared quite easily. The concentration of the solution is prepared depending on the stage at which the tomatoes grow. You can prepare the following composition: 100 g of fresh bird droppings are added to 10 liters of water, infused for 24 hours and the plants are watered. Top dressing with manure with bedding is applied during tillage, in the ratio of 6 kg of fertilizer per 1 sq. m. Chicken manure is not a universal fertilizer, therefore, in addition to it, it is necessary to add other top dressing to the soil, such as ammonium nitrate, superphosphate.

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.

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.

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.

Self-fertilizing tomatoes during planting

During the flowering of the second and third flower brushes, the plants are sprayed with a solution of boric acid (1 teaspoon per 10 liters of water). For cucumbers Top dressing. At the beginning of flowering: for 10 liters of water - 1 teaspoon of potassium sulfate, urea, superphosphate and 1 cup of mushy mullein (or 1 tablespoon of sodium humate).

As a rule, there is usually enough heat for vegetables in greenhouse conditions, so feeding the tomato in the greenhouse requires the main attention.

The solution in the barrel ferments very actively and the stench, sorry for the details, is not the most pleasant. And you need to mix the fertilizer at least once a day. All this is infused for 1.5-2 weeks. Then I take out the fermented grass. When it dries up, I put it under the zucchini. Why under the zucchini - I do not know. It's been like that from the very beginning. Zucchini are very grateful.

They often ask: is it permissible to feed tomatoes during fruiting? I answer: after the ovaries have appeared, top dressing is only under the root, that is, root.

Lactic acid solutions (whey) with the addition of 0.5 cups of sugar (10 liters). And when we apply the solution to the surface of the leaf, then all the nutrients pass through the leaf into the plant. And it happens very quickly. Therefore, foliar acts much faster than root. Secondly, it is used to quickly help a plant suffering from a lack of one or another trace element. I try to use foliar dressing more often for seedlings, for plants recently planted in open ground or a greenhouse, that is, for younger seedlings.

Fertilizer methods for tomatoes

For a good result, it is not necessary to use expensive fertilizers, the main thing is not to exceed the dosage and apply them to the soil in time.

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 quickly respond to their needs, constantly take care of them, you can get a crop of tomatoes in a greenhouse much more abundant and better.

To cook it 1st. a spoonful of fertilizer is diluted in 10 liters of water

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 feed the tomatoes with any complex mineral fertilizer.

Mineral fertilizers play an important role in the process of growth and development of tomatoes.

During fruiting, 3 top dressings are required. First: for 10 liters of water - 1 cup of mushy chicken manure and 1 tbsp. spoon of nitroammophoska, per 1 m2 - 5 l.

Sometimes tomatoes grow well, but they do not bloom for a long time. They only intensively develop stepchildren. In this case, such top dressing of a tomato in a greenhouse, such as phosphorus and potash, will help. In some cases, wood ash also works well at the rate of half a glass for each bush.

You can try this mulch on other plants.

I do foliar spraying during the first half of the growing season. That is, as soon as I noticed that the first tomatoes started, I stop feeding by spraying. And I continue to do the root throughout the entire growing season (development) of tomatoes.

All these foliar solutions are very effective in nourishing and protecting tomatoes from diseases, especially late blight, other fungal diseases.

For foliar dressing, lower concentrations of the solution are used than for root dressing, so as not to cause leaf burn. For it, fertilizers are used that completely dissolve without sediment, which do not contain chlorine. Usually these are liquid forms of fertilizer mixtures, no matter what they are - mineral or organic. Try to use non-chlorinated water for preparing nutrient solutions - rainwater or at least settled tap water.

Stages of growing tomatoes in the garden

Nitrophoska and other complex fertilizers are applied during seedlings of tomatoes, 0.5 teaspoon per 1 liter of water.
Watching a video detailing the various types top dressing tomatoes, you will see that you yourself can easily cope with a similar task.
So, if you think that the soil in your greenhouse is well fertilized, then fertilizing after transplanting tomato seedlings can be omitted. Then, rough plan dressing will be like this:

We list the most significant fertilizers for this crop:

The second - 10-12 days after the first feeding: for 10 liters of water - 0.5 liters of mullein and 1 teaspoon of potassium sulfate (or for 10 liters of water - 1 tablespoon of Fertility). For 1 m2 - 5-6 liters.

Top dressing of tomatoes in the open field and greenhouse - practical experience

Most of all, top dressing of tomatoes in a greenhouse is necessary during the flowering period and during the formation of fruits. There are frequent cases when there is an abundance of fruits on the bushes, but they do not ripen.

A little more than half of the nutrient infusion in the barrel is obtained. I top up the barrel. I take a ready-made infusion (500 ml), add it to a watering can with water (6 liters), water tomatoes, cucumbers, eggplants, pumpkins - half a liter of solution for each bush. Yes, I almost forgot. The effect will be better, and top dressing will not bring harm (there will be no root burn) if the soil under the plants is wet. That is, before root dressing, be sure to water the tomatoes in the open field or greenhouse with settled water, if you use tap water or rainwater.

Types of dressings of tomatoes

The second popular question: feeding tomato seedlings after picking - how and when. The first time you should feed the tomatoes 10-12 days after planting the seedlings. And what and when read above.

You need to apply them not at the same time, but, either in turn, as it is written, or choose those that, in your opinion, will bring the greatest benefit to the plants. With the accumulation of experience, you yourself will determine "what is yours."

Both root and foliar top dressing are equally useful for both open ground and greenhouse tomatoes. During the first half of the growing season of plants, it is better to alternate them. In the second - go to the root. Greenhouse at high humidity should be aired more often, especially after spraying. In order for the plant to get the maximum benefit from any fertilizer, you need to know when - in the morning, in the afternoon, in the evening - it is better to carry them out.

Planting tomatoes begins with the use of superphosphate, 1 tablespoon per well.

Tomatoes are a fairly demanding vegetable crop. This plant actively takes nitrogen, potassium, phosphorus and other minerals from the soil. During seed germination, phosphorus is necessary to enhance the growth of plant roots, it contributes to earlier flowering, ripening of tomatoes, increases yield, sugar content and dry matter in fruits. Potassium is necessary for normal fruiting, and nitrogen in ammonia form is necessary for rapid maturation fruits. During budding, flowering and fruit formation, plants need nitrogen-potassium nutrition. If there is a lack of nitrogen or potassium, then plant growth is weakened, and this leads to a decrease in fruits and a decrease in yield.

During the formation of the ovaries, it is necessary to feed the tomatoes with a solution of 2 l of wood ash and 10 g of boric acid, diluted in 10 l hot water. The prepared solution must be insisted for a day so that all the elements are completely dissolved. This mixture contains a large number of micro and macro elements that will help the crop to form more quickly. Water each plant with 1 liter of the prepared working solution.

The first feeding will be carried out approximately

potassium;

The third - 12 days after the second: for 10 liters of water - 0.5 liters of mullein or 1 cup of mushy chicken manure, 1 tbsp. spoon of nitroammophoska (or 1 tbsp Bogatyr). For 1 m2 - 5-10 liters. Mullein and chicken manure can be replaced with sodium humate, Ideal, Breadwinner, Fertility, Giant - 1 tbsp each. spoon.

To speed up the browning process, many resort to a procedure such as foliar top dressing of a tomato. For this, superphosphate is used. The composition is prepared as follows: forty grams of the substance (or approximately two matchboxes) are dissolved in one liter of hot water, left for a day, and then diluted with nine liters of water. Many are interested in the question of how to recognize what tomatoes lack and how to help them.

I really like the result of such organic feeding - the plants are always green, they look healthy, they tolerate bad weather well, they grow very quickly, a lot of fruits are tied and, it seems to me, they began to get sick less, that is, their immunity has increased.

Desirable, I would even say, foliar and root dressings are required when tomatoes begin to bloom. Do not miss the deadlines - the number of ovaries and the harvest will depend on this.

Alternate foliar top dressing with root. Below is again the experience of our reader from Novokubansk.
One reader of our blog - Anna Nepetrovskaya from Novokubansk - shared her experience in using foliar and root dressings of tomatoes. The experience, as far as I can appreciate, is invaluable.
5 days after planting, you can water the tomatoes with a weak solution of potassium permanganate.
Tomatoes have high nutritional, taste and dietary qualities.
The last root dressing of tomatoes is carried out during mass and active fruiting in order to accelerate maturation and improve palatability. 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 15-20 days
phosphorus;
For root rot: 2 tbsp. tablespoons of copper sulfate - for 10 liters of water, 1 glass per plant. If cucumber leaves become prickly and rough after fruiting: 1 tbsp. dilute a spoonful of urea in 10 liters of water, spray on the leaves. cheat sheet for the summer Here about all the plants. What and what to feed.
I must say that sometimes even experts find it difficult to answer this question. If the bush is large, there are a lot of dark green leaves on it, then this means that the top dressing of the tomato in the greenhouse was done with fresh manure and it is not worth watering it further.

This solution can be carried out root and foliar top dressing. I usually spend foliar on young plants planted in open ground or in a greenhouse. Watering under the root - every 10-12 days.

In a greenhouse or open field, top dressing is carried out as follows. Each plant needs to be fed individually. If the soil under the plants is dry, then before feeding it is necessary to slightly moisten the soil. Watering the tomatoes clean water, the temperature of which is not lower than 20-22ºС. When watering in a greenhouse, try not to get water on the leaves - excess moisture is useless there. Water in the morning - after that, be sure to ventilate the greenhouse. And after watering, pour half a liter of nutrient solution under each tomato bush.

Anna advises that before each fertilizer, pour the tomatoes under the root with clean water - settled tap or rain water.

Root top dressing of tomatoes

Look at Anna's tomato alleys! Is this not proof that the feeding strategy was chosen by her correctly!

In autumn, when digging the soil, 4 kg is applied per 1 square meter of humus or compost;

Excess nitrogen negatively affects the growth of tomatoes. It delays fruiting, there is a high probability of plant diseases.

In any case, there is no clear instruction on when, how often and with what fertilizers to feed 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.

after transplanting plants. Mineral fertilizers are used for it, diluting them in 10 liters of water:
nitrogen.
There is such a rigmarole called "FLORA-S"
And it happens the other way around: the bush does not grow well, it has pale leaves. In this case, you need to use nitrogen fertilizers - urea, nitrate, and better in combination.
I have had enough of this solution for a long time. But everything, of course, depends on the number of plants planted. If I feel that there is not enough “green fertilizer”, then after less than half of it remains in the barrel, I fill the barrel with new grass. I don't add anything else but water. I wait 10-15 days - a new nutrient solution is ready.

When to Feed Your Tomatoes

I try to do foliar spraying of tomatoes in the greenhouse in the morning so that the nutrient solution is absorbed by the evening. At night, the plants should be dry.

The first root dressing - not earlier than 10 days after planting seedlings.

How often should you fertilize

Tomato alley of Anna Nepetrovskaya (Novokubansk) - Cio-Cio-San variety

In spring, it is necessary to fill the soil with mineral fertilizers: 80 g per 1 square meter of superphosphate and 20 g per 1 square meter of potassium chloride;

So in order to get good harvest tomatoes, you need to create all the necessary conditions.

In addition to the usual root top dressing of tomatoes, it is 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 not enough for the plant.

25 g 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. Symptoms of phosphorus starvation in tomatoes are the appearance of red-purple spots on the underside of the leaves, as well as twisting of the leaves along the main vein, and fruit ripening also slows down.

How to feed tomatoes in a greenhouse or open field

Often a purple hue appears on seedlings or on the trunk. This is a consequence of the lack of phosphorus. Although it is usually found in the soil, for some reason it is poorly absorbed. If there is too much phosphorus in the soil, then the leaves on the bushes begin to turn yellow or curl. This means that the next feeding of tomatoes in the greenhouse should not contain this element.

This "green manure" works well against late blight. At least, it seems to me that after I started using it, there were almost no cases of phytophthora on leaves, fruits. In 2013, only a few tomato fruits (5 pieces) growing in open ground were thrown out from one bush. On the rest of the bushes, I did not notice any signs of phytophthora. And for the next two years, my tomatoes did not have phytophthora either. Although I suspect that the reason for this is not only top dressing, but also a dry hot summer.

If you have little time to care for tomatoes or it is difficult to find all the components of top dressing that Anna Nepetrovskaya advises, then you can use humate-based fertilizers.

The second - 15 days (two weeks) after the first.

Start feeding tomatoes should be a week after planting.

How to make your own organic "green manure"

After planting seedlings, in 10-15 days they plan the first feeding, and the second - already at the beginning of fruit formation;

To do this, planting tomatoes is in the soil, prepared in advance and fed with mineral organic matter.

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 introduce the same elements through root dressing, then the result can be seen only after a week or two.
40g phosphorus;

When thinking about how to feed tomatoes in a greenhouse, you should remember the high consumption of potassium by this crop. This mineral contributes to the formation of stems, as well as the absorption and processing of carbon dioxide. In case of potassium deficiency, lower leaves accumulate ammonia nitrogen, as a result of which they first wither, and later die off. In the photo you see how the result of potassium starvation of tomatoes on the leaves appears:

Feeding cucumbers - soak dried bread (leftovers)
In general, cultivation vegetable crops in greenhouse conditions implies the existence of a certain calendar, which indicates the periods of ongoing work, including the introduction of fertilizers

But, for example, the 2014 garden year began with rainy weather. Humidity, both in the greenhouse and in the garden, is high. To prevent the appearance of late blight (tomatoes), powdery or downy mildew on cucumbers, zucchini, I additionally treat the plants with a solution of whey (1 liter per 10 liters of water), to which I add 10 drops of iodine. This solution is especially beneficial for tomatoes. Iodine helps to increase the number of ovaries, and whey inhibits the growth and development of pathogenic fungi.

I used Kuznetsov's GUMI (a natural fertility elixir) - the plants responded to it with good appearance and harvest. For 10 liters of water - 2 tablespoons of elixir.

The third top dressing will be most effective during the beginning of flowering, namely during the flowering of the second brush. On the first flowering brush, many gardeners advise cutting off the first double flower, since the fruit on it is most often tied up ugly, different from the others. (But I would not call this recommendation mandatory - I very rarely saw such a flower on my tomatoes).

Here are the compositions of foliar top dressing she uses:

In order for the fruits to set sooner, use a 0.5% solution of superphosphate or a solution of boric acid. The solution that has settled is drained and sprayed with tomatoes.

Soil enriched with organic materials and biofertilizers is the key to a rich harvest of tomatoes.

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

15g potassium.

Insist for a day, two, stir

The first top dressing of a tomato in a greenhouse is carried out on the eighth day after planting. Bushes under the root are watered with a solution of mullein at the rate of one part of fertilizer per ten parts of water. The consumption of the solution is calculated from the ratio of one liter for each bush. Root watering requires care not to erode the soil.

For the prevention of late blight, I alternate treatments. Once with a solution of whey, and the other with a solution of Fitosporin. This drug not only protects tomatoes from the development of late blight, it also nourishes the plants with bioactivated microelements, especially its new modification - Fitosporin-M. Sometimes I skip lactic acid treatment, but I definitely replace it with a Fitosporin solution, which well suppresses the development of fungal and bacterial diseases on plants.

Tomatoes are self-pollinating plants. accompanied by the formation of new ovaries, and as a result - new fruits. Since tomatoes are self-pollinating plants, they do not require the presence of insects. During flowering, it is only recommended to slightly shake the branches on which the inflorescences are located. You can also tap the stem every 4 days during flowering so that pollen from the upper flowers falls to the lower ones.

The most favorable temperature during flowering is + 22-25 degrees. Therefore, the most favorable place for their cultivation is a greenhouse where the air temperature can be controlled. During flowering, high relative humidity should not be allowed, the air should be rather dry.

Caring for tomatoes during flowering

Very important proper care for tomatoes during flowering. By by and large it comes down to timely watering, pinching and feeding. Watering plants during this period should not be too plentiful, in moderation. Do not allow tomatoes to be waterlogged. When watering, it is also impossible to allow droplets of water to fall on the leaves, since dampness can provoke the development of late blight.

Top dressing of tomatoes during flowering

flowering tomato- This is a very important stage of fruit ripening. During flowering, the second feeding of plants is carried out. If during the first top dressing we used nitrogen fertilizers to accelerate the growth of green mass, then this time special emphasis should be placed on potash top dressing.

At the same time, it must be remembered that tomatoes really do not like an excess of fertilizers in the soil - they begin to stretch, the inflorescences fall off without setting the ovary. Correctly determine the dosage of top dressing - this is half the battle done.

As mentioned above, the emphasis should be on potash fertilizers. Potassium is just necessary for the formation of new fruits. In no case should we forget about phosphorus, it is necessary at all stages of plant growth, including during flowering. Phosphorus helps to strengthen the roots.

Ash is very good as a fertilizer. For top dressing, along the rows - make small grooves 10-15 centimeters from the plant, lay ash there, sprinkle with earth and water.

The introduction of small portions of biohumus has a very positive effect on the development of tomatoes during flowering. It is best to do this when loosening.

Pasynkovanie tomatoes during flowering

During flowering, it is necessary to pinch tomatoes. During this period, it is necessary to help the bush to form correctly. Stepping is done so that the plants give more fruits and that they are larger.

Pasynkovanie is the removal of the lower side leaves and stepchildren.

During flowering, a second pinching is performed.

Pinching will not only promote better fruit formation and ripening, but will also protect your plants from late blight.

- this is very important process, which will directly affect the yield. At this time, your plants need special care, following which you will get the desired harvest!

Top dressing of tomatoes during flowering:

Finally, the period of major unrest is over: tomato seedling rose and took root in the greenhouse. In anticipation of the flowers, it is worth considering how to help the bushes in this difficult time for them. Top dressing of tomatoes during flowering in a greenhouse is a mandatory procedure, because plants will need strength.

Tomatoes will not be able to fully develop in greenhouse conditions without mineral supplements. The leading role in this case will be played by such trace elements as potassium, phosphorus and nitrogen. At the same time, special attention should be paid specifically to phosphorus-containing fertilizers - without them, the plant will not be able to fully assimilate nitrogen and other micronutrients.

A lack of phosphorus will be indicated by the appearance of characteristic purple spots on the leaves, a slowdown in the development of ovaries. When thinking about what to feed your tomatoes during the flowering period, remember that plants growing in a greenhouse consume an increased amount of potassium, thanks to which the bushes can absorb carbon dioxide normally. With a lack of potassium in tomatoes, the lower leaves gradually wither and die.

Some gardeners successfully use ... ordinary yeast as a fertilizer! Surprisingly, they are the source of most of the nutrient compounds vital to the crop. The recipe is as follows: 1 package of ready-made dry yeast is mixed with 2 tbsp. l. sugar, add some water. In this form, the mixture should stand for some time, and then it is diluted in 10 liters of water. This is a ready-made solution, 0.5 liters of which will be enough for 1 garden watering can. The effect of feeding will be noticeable in a couple of days. It is advisable to use such recharge twice a season.

When and how to contribute

Top dressing of tomatoes during flowering in a greenhouse is far from a one-time procedure.

As a rule, it is customary to feed seedlings for the first time at the time of landing in a permanent place. A little humus is placed in the prepared planting pits, ash is added. Further, the opinions of professionals differ: some believe that the time for the next feeding will come no earlier than in 14 days; others prefer to support the bushes and feed them with "green tea".

The last miracle remedy is easy to prepare: you will need 1 kg of chopped greens (any grass and weeds will do), 250 g of ash and 1 bucket of mullein. All components are mixed and left to brew for 4-5 days. After that, the amount of solution should be doubled by adding clean water. Everything, the tool is ready for use!

This top dressing will require about 2 liters per plant. Experienced gardeners are unanimous only in the opinion that mineral fertilizers should not be used for newly planted tomatoes. The fact is that such substances act on plants extremely unevenly: some bushes begin to actively increase their green mass, while others, on the contrary, begin to bloom intensively.

Thus, the approximate scheme for applying top dressing is as follows:

the first feeding is carried out at the time of transplantation in the manner described above;
next time fertilizer will be needed after 2 weeks. For this, complex mineral fertilizers are used, which include potassium, phosphorus and nitrogen;
This is followed by the most crucial stage - the beginning of flowering. During this period, top dressing of tomatoes in the greenhouse is vital, since during flowering they expend vital energy beyond measure. And then, the fruits are yet to be tied. At this stage, it is customary to use organic matter: 0.5 l of mullein mixed with bird droppings, and 1 tbsp. l. potassium sulfate is diluted in 10 liters of water. Each plant should get at least 1.5 liters of solution;
after that, they feed the tomatoes already during the formation of the ovaries. Now you can take 2 liters of ash, 10 g of boric acid and 1 bucket warm water. We mix everything and leave to infuse for a day. We water the beds at the rate of 1 liter for each plant;
and the last time feeding will be needed when the tomatoes begin to actively bear fruit. So your crop will ripen faster, and will have best qualities. This time use sodium humate and superphosphate (1:2). Fertilizers are diluted in 10 liters of water, then the beds are watered.

Video "Feeding tomatoes during flowering"

From this video you will learn how to feed tomatoes during flowering.

Tomatoes, like many other nightshades, are sprayed to protect plants from pests and pathogens. various diseases. As a rule, fungicidal preparations of natural and chemical origin are used for this purpose. They allow you to prevent, for example, the development of such a dangerous disease as late blight.

Also, spraying of tomatoes is carried out in order to perform foliar top dressing. Nutrients that fall on the leaves of these cultivated plants, allow tomatoes to get stronger faster and give a better harvest. Often, aqueous solutions of whey, urea, iodine and calcium nitrate are used as foliar top dressings. Usually the procedure is performed in the evening on calm days.

And, finally, the purpose of spraying may be to stimulate tomato bushes to form ovaries. Usually such spraying is carried out during the flowering period of the second and third brushes of the plant. The goal is to help the pollen "sprout". For this, boric acid is used (10 g of boric acid per 10 liters of settled water). Such spraying is safe, therefore, throughout the entire flowering period, tomato bushes can be sprayed up to 5 times at regular intervals. Procedures should be carried out in the morning or evening, in clear calm weather.

Instead of boric acid, you can use vinegar (1 tablespoon of acetic acid per 10 liters of water). Also, like boric, such spraying promotes the formation of ovaries and at the same time protects tomatoes well from late blight.

So you are interested in how to increase the yield of your tomatoes, namely, you want to know how and with what to feed tomatoes in a greenhouse during the season: after planting seedlings before flowering, during flowering and during the period of active fruiting.

Below you will find information on how to properly fertilize tomatoes in a greenhouse, what fertilizers are best used from planting seedlings to harvesting.

It should be understood that tomatoes need to be fed as needed. In other words, if you properly filled the soil with nutrients during the preparation of the beds (or put it in the hole), then most likely you will not need any top dressing.

But! If the plant begins to signal that something is missing, then you have no choice: you need to fertilize, and as soon as possible.

When tomatoes urgently need top dressing - signs of a lack of macro- and microelements

Sometimes in the process of development, tomatoes themselves indicate a lack of a certain element in the diet. This is expressed by characteristic external signs (as a rule, it is on the leaves).

nitrogen deficiency. Plants begin to lag behind in growth, stretch out, the foliage becomes smaller and acquires a pale green color with a yellow tint, the stem becomes thin and soft.

Phosphorus deficiency. The plant as a whole darkens, more precisely, its leaves acquire a bluish tint with purple veins, and can also wrap inwards.

By the way! More information about the reasons why tomatoes can curl leaves, you can find .

Potassium deficiency. Expressed curling the tips of the leaves and a characteristic brown border along their edges (they also say what is happening marginal burn).

If not enough zinc, then the leaves become very fragile and rough (rough) and can also curl downwards, and orange-brown chlorosis forms on older leaves.

If not enough boron, then the leaves lighten up and twist again.
With a lack copper and sulfur, young leaves usually wither, and then may turn bluish-green in color and curl upwards ( into a tube).
Flaw calcium manifested in the fact that the leaves streaks turn white, and they themselves curl up.

Note! More information about the reasons why leaves can curl in tomatoes, you can find .

When there is a shortage gland- leaves turn yellow and droop, while also sometimes twisting.

Flaw magnesium.

In this case, you need to top dressing with a certain macro- or micro-fertilizeror complex microfertilizer, for example, Humat +7 or similar.

Feeding methods

There are 2 ways or types of feeding any plant (including tomatoes):

root (watering under the root);
foliar or foliar (by leaves).

Root top dressing imply the application of fertilizers directly under the root of the plant, as a rule, in liquid form(i.e. the solution is prepared first = granular or liquid fertilizers are dissolved in water). Most often, this is how macronutrients.

Although you can also apply fertilizer first dry(especially), and then already irrigate.

Concerning foliar (leaf dressings), then they are used as additional ones, since they are most effective when the plant especially needs certain trace elements(which is shown in appearance), in other words, they are carried out as needed.

Although sometimes the leaves are fed with complex fertilizers such as calcium nitrate (nitrogen + calcium).

Interesting! Foliar feeding increases the digestibility of fertilizers during critical periods of growth and development, thereby compensating for the deficiency of macro- and microelements and improving the efficiency of fertilizer application (increases the availability of other nutrients, especially against the background of nitrogen application).

Feeding rules

For feeding, you should choose morning or evening hours, or daytime if worth overcast weather.
Feeding is very convenient combine with irrigation.

Directly before applying mineral fertilizer anyway you need irrigate, because it is always recommended to feed on moist soil.

Exemplary liquid fertilizer consumption for 1 plant - about 0.5 liters.
Feeding is better regularly, every 7-14 days to constantly feed the plant (you can do this more often, while necessarily reducing the concentration of fertilizer).

By the way! Tomatoes begin to consume food from the soil especially intensively when the 3rd brush is tied up and the 4th one begins to bloom. It is during this period that it is necessary to begin to actively feed the tomatoes with potash fertilizers (with the addition of calcium, magnesium, boron), and doing this every 5-7 days.

Scheme for feeding tomatoes in a greenhouse: what fertilizers and when to use

Like all plants, tomatoes require the whole complex of macro- and microelements, namely: nitrogen, phosphorus, potassium, and especially magnesium, calcium, boron, iron, zinc and other micronutrients.

There are three main stages of feeding tomatoes in a greenhouse: after planting in the ground (before flowering), during flowering and the formation of ovaries, and during fruiting.

As a result, you need to make about 5-7 root dressings and 1-2 foliar dressings (per leaf):

nitrogen - under the root (you can skip and go straight to the next one).

nitrogen-calcium - under the root or along the leaves.

nitrogen-phosphorus-potassium top dressing or phosphorus-potassium.

spraying with boron on leaves and flowers.

nitrogen-calcium - on the leaves (if necessary).

potassium-nitrogen supplement.

potassium supplement.

potassium supplement.

potassium supplement.

After planting in the greenhouse: before flowering and during the budding period (beginning of flowering)

Potassium nitrate(20-30 grams per 10 liters of water);

13.6% nitrogen and 46% potassium.

Borofoska (15-20 grams per 10 liters);

It also includes phosphorus (10%), calcium (20%), potassium (16%), magnesium (2%). In other words, all the nutrients necessary for tomatoes.

Kalimagnesia (15-20 grams per 10 liters);

Kalimagnesia (kalimag) contains, in addition to potassium (about 26-28%), also magnesium (about 8-9%).

By the way! As magnesium fertilizer magnesium sulfate or magnesium nitrate can be used.

Potassium monophosphate (10-20 grams per 10 liters of water);

Potassium monophosphate is the fastest and most easily digestible form of phosphorus-potassium fertilizer (phosphorus - 50%, potassium - 33%).

However, such a fertilizer will be quite expensive, and besides, tomatoes do not need such an amount of phosphorus. Although, if your soil is rather poor, then you can use it.

It is also very good to feed tomatoes with various humates, especially potassium humate. Moreover, it (potassium humate) can be mixed with others mineral fertilizers.

Or you can use Humate +7 with micronutrients.

Specialized fertilizers for tomatoes

Of course, if you don't want to bother with the selection and preparation of certain fertilizers, then the easiest way is to feed with special fertilizers for tomatoes (which are also suitable for peppers and eggplants). They already, as a rule, have all the macro- and microelements necessary for the culture (use and dilute everything according to the instructions on the packages):

Agricola for tomatoes, peppers, eggplants.

baby from Fusco"Tomatoes, peppers, eggplants."

Gumi Omi"Tomato, eggplant, pepper."

Hera for tomatoes, peppers and eggplants.

And many others.

Answers to the most popular questions about feeding tomatoes in a greenhouse

In general, all the answers have already been given above, but if you want answers to specific questions, then here they are.

How to feed tomatoes in a greenhouse so that they are plump?

Naturally, all gardeners dream that after planting in the greenhouse, tomato seedlings take root as quickly as possible and enter the fruiting phase.

But if the seedlings have a thin, elongated stem, then you can not count on a good harvest. Therefore, it is so important that during the active growing season they receive good nutrition and grow plump stems that can withstand the load of the future harvest.

In order for the tomatoes in the greenhouse to be plump, they should be fed 10-14 days after planting nitrogen, and also better nitrogen-calcium fertilizers, in other words, it is:

, (you can directly on the leaves), calcium nitrate, bird or chicken droppings, mullein, green manure (infusion of herbs, usually nettle).

How to fertilize tomatoes during flowering so that there are more ovaries?

Root, and preferably foliar (leaf) top dressing of tomatoes will help you with this. boron. It is boron that will help the tomatoes tie the maximum number of fruits, especially if during their flowering period there is unfavorable weather (for example, elevated temperature).

Thus, as a means for feeding tomatoes with boron during flowering, you can use:

boric acid (5-10 grams per 10 liters);

By the way! Alternatively, you can use a pharmacy solution of boric acid, but the usual one is better.

special drug Boroplus.

And also such special preparations, how "Tomato" or "Ovary"(it happens like for tomatoes, So universal for all cultures).

How to feed tomatoes so that there is no blossom end rot of the fruit?

Calcium fertilizers are used to prevent blossom end rot. So, before flowering and/or after fruit set can be used such complex fertilizer as calcium nitrate, which contains nitrogen - 14.9%, calcium - 27%.

By the way! You can do both root and foliar (foliar) top dressing, i.e. spraying.

How to feed tomatoes to ripen faster?

Potash fertilizers are your choice. Exactly thanks to potassium your tomatoes will rather mature and fill with colors.

As for specific fertilizers, these can be the following:

solution-infusion (100-200 grams per 10 liters of water).
potassium nitrate (20-30 grams per 10 liters);
potassium magnesia (15-20 grams per 10 liters);
potassium monophosphate (10-20 grams per 10 liters).

Thus, if you feed the tomatoes in the greenhouse correctly and on time, you will definitely be able to get a rich harvest of delicious and sweet tomatoes.
