Tomatoes are blooming, but tomatoes are not. The best folk remedies for tomato ovary

When growing tomatoes, you should follow some recommendations if you want more harvest. The bush can give its strength either to leaves or to fruits. He should help him a little in this and then nature will reward you with a good harvest ...

1. Do not prepare too rich nutrient soil for this crop in the greenhouse. Introduce (even from autumn) manure or feed the mullein during the growing season.

2. Do not water the tomatoes in the first 2-3 weeks after planting (especially those produced in early dates). The water poured into the holes is quite enough for the normal rooting of plants. And a small restriction with watering only activates the further development of the soil by the roots. It should act for the entire first half of the growing season before the start of fruit setting on the first cluster.

But it is not worth bringing the soil to a strong drying out. This is dangerous for all tomatoes. Plants may stop growing and flowers may crumble. The watering rate is increased only when the mass filling of fruits begins. Finding out if there is enough moisture in the soil is easy. I take a handful of earth from a depth of 10-15 cm and squeeze it in my palm. If the lump has not disintegrated, there is enough moisture. Decayed - watering is required.

Frequent watering of tomatoes in small doses contributes to the formation of a superficial root system, which makes plants less resistant to external factors.

3. There is no need to overfeed tomatoes with nitrogen at all stages of the growing season. Fatty plants actively increase only green mass, postponing fruit setting for later.

From personal experience:

As soon as I see that my tomatoes are starting to grow violently, I give them a little stress. He makes plants think about procreation and start laying flower brushes and pouring fruits. You can stop fattening by reducing watering. Removing one to three large lower leaves helps a lot.

4. One of the types of fattening of tomato plants is the growth of flower brushes (when a new shoot begins to grow on their tops at the time of fruit setting). Tall tomatoes with a long flower cluster are especially affected by this. You need to pinch such a brush, leaving no more than 5-7 fruits on it. Typically, the above measures will return tomatoes to a “working condition”.

5. No nitrogen fertilization after planting (unless the plants clearly suffer from a lack of nitrogen).

I give the first root dressing only when the 5-6th brush begins to bloom, and then only potash. I compensate for the lack of magnesium and trace elements by spraying the leaves with solutions of these elements.

Many tomato growers complain that they have nursed and planted seedlings, but there are no fruits on it. Tomatoes bloom themselves bloom, then the leaves fall off and the stalk turns yellow. What is the reason for this phenomenon? Why is this happening?

If your tomatoes are blooming, but there is no ovary, then this may be for the following reasons:

1. Air temperature.

Very often flowers fall due to very high temperatures (sometimes very low) and not very optimal humidity. The fact is that the flowers are pollinated under comfortable conditions, when the air temperature is +28 - + 29 ° C during the day, and +13 - + 21 ° C at night. If the cold weather lasts a long time, then the ovary will no longer be on it. If the air temperature rises to + 40 ° C, then the discharge of flowers is almost guaranteed. If at night the temperature does not drop below 25 ° C, then such a temperature, oddly enough, will also be detrimental to the future harvest. The thing is that at a temperature of + 20 ° C the tomato “rests”, and if the temperature is higher, it cannot do this. The temperature makes it difficult for him to rest.

If you are growing tomatoes in a greenhouse, then you need to provide the plant with warmth. Put on a heater overnight. You can also pour warm water over tomatoes in the evening in the hope that the earth will keep warm until the morning.

Why there is no ovary on tomatoes in the greenhouse is the lack of pollination. v open ground flowers are pollinated by insects, and in the greenhouse the plants are deprived of this. The conditions for pollination in the greenhouse must be created artificially.

2. Air humidity.

Tomatoes are perfectly pollinated at a humidity of 40% to 70%. It is very easy to raise the humidity of the air. To do this, you will need to spray the bushes with water in the morning, but it is much more difficult to reduce the humidity. In those regions where there is high humidity, it is imperative to mulch the crop and rarely water the tomatoes with a bottle without a bottom, which are dug in near the bushes.

3. Lack or excess of nitrogen.

Whoever says what, but tomatoes still love nitrogen. But experienced gardeners know well that if the tomatoes are overfed with nitrogen, they will begin to fatten. A sufficient amount of oily foliage grows on them, the stem is beautiful and thick, and the color of such a bush will be sluggish, there will be few flowers in the brush, and even those will fall off. Therefore, many are afraid to overfeed tomatoes, and as a result, they are not given enough nitrogen. And again, a disastrous result awaits them. In undernourished tomatoes, the first cluster grows well and blooms, and on the second and third, the fruits are reluctantly tied. When the first brush is poured, then the need for nitrogen decreases, the plant begins to tie the third and fourth brush, for example, skipping the second.

It is not difficult to deal with such a reason. It will be enough to regularly fertilize the tomatoes with nitrogen.

There are other reasons:

What to do? How to deal with this problem?

It is necessary to use drugs that basically contain boron or plant hormones. Why boron? Boron is an important trace element in plant life. It is able to normalize the synthesis of nitrogenous substances, improve metabolic processes and increase the content of chlorophyll in the leaves. When the nights are very cold, cloudy weather, when pollination does not occur, they should help in this matter. But not always.

To improve the ovary of tomatoes, you need to spray with boric acid. Top dressing from boric acid solution can be both root and foliar. To prepare the solution, take 1 g of boric acid, dilute in a liter hot water... Spray the tomatoes with an already cooled solution. Using boric acid for tomatoes will give you nice results... You can spray with a product based on copper. Tomatoes were sprayed with boric acid to fight late blight. Spraying boric acid on tomatoes will greatly increase the yield of your plants. There is also special means to speed up the ovary, which you can purchase in the store or in the market.

It will be wise, especially in a greenhouse, in dry and sunny weather, to shake the bushes in the morning. This way we can help the pollen get to the pistil. Why do we do this in the morning? Because the sun is very hot in the greenhouse by noon and the pollen is already unable to fertilize.

At the peak of the heat, the air must be sprayed with clean water, the temperature will drop slightly.

Ash is great for solving ovary problems. It helps the fruit to set on the tomatoes. It will be enough to sprinkle ash around the crop or dilute it in water and water the tomatoes with the resulting solution.

Very often, under the same conditions, some varieties of tomatoes knit brush by brush, while others stand almost without fruit. You need to memorize these varieties of tomatoes. If they delight you for 2-3 years, then they can be left on the list of your favorite tomatoes. You need to know that hybrids can knit fruits in unfavorable conditions.

Tomatoes are blooming but there is no ovary what to do

This article will focus on the topic: tomatoes are blooming, but there is no ovary and what to do with this problem.

The first thing to talk about when solving a problem is about the reasons.

Why aren't tomatoes tied?

Unfortunately, this problem is quite common. There may be several reasons.

Early planting of tomatoes in open ground. This culture loves warmth, any temperature deviations below the norm can cause pollen maturation to be inhibited. The optimum temperature is 20-25 degrees. If it gets below 15 degrees, then all processes slow down. At the same time, tomatoes also do not like heat. Temperatures above 35 degrees cause the plant to become sterile.

Incorrectly selected variety. Some types of tomatoes are too sensitive to temperature vagaries of nature. Even small differences can ruin the harvest.

Insufficient moisture is another reason that fruits do not set on tomatoes. The optimal performance is 70-75%. But it is not easy to determine by eye what the moisture content of the soil is. This is where simple observation comes in. If the leaves of the tomatoes are drooping, the soil is cracked or just very dry, then it is clear that the tomatoes suffer from a lack of moisture. Even at the stage of seedling formation, dry soil can lead to inhibition of development and subsequently to the flying around of flowers.

Lack of wind. If the weather is calm outside, then pollination cannot take place. To solve this problem, you need to shake the tomatoes with your hands.

Seeds. Most often, tomatoes grown from their own seeds are poorly set. This is due to the fact that the seed was not processed from diseases. All plants that have undergone the disease begin to throw off flowers.

Thickening of the landings, the presence of stepchildren. Make sure that this does not happen.

Lack or excess of fertilizer. Tomatoes are one of those crops that takes all the nutrients from top dressing as much as possible. She loves them very much. Therefore, if the soil is poor, then this can be the main reason that the tomato blooms, and the fruits are not set. An excess of nitrogen, in turn, causes the raging development of green mass, while the ovary is not formed.

Let's talk about the last point, since everything is more or less clear with the previous ones.

How to feed tomatoes so that the fruits are tied.

We will talk about traditional preparations and folk remedies for feeding.

An important point!

You should not overfeed the seedlings so that the tomatoes set faster. As mentioned above, an excess of fertilizer leads to the formation of thick and strong tops. In addition, we remember that tomatoes take everything from fertilizers to the maximum.

So, you can feed with the following drugs:

Such feeding as "Effekton", "Ovyaz", "Agricola", "Kemira Universal" are very widespread and in demand. They must be brought in according to the instructions on the package. But at the same time, the first feeding does not need to be started earlier than 3 weeks after planting in the ground. After these preparations have been introduced, you need to wait until the ovary is formed. Then add additional fertilizer. Can be used folk remedies and foliar feeding.

Simple and affordable recipes from the people: these are eggshells and yeast. The first saturates tomatoes with calcium, the second provide many useful components.

What to do as a top dressing so that tomatoes are tied, from shells and yeast.

The recipes are very simple and accessible to everyone.

Take eggshells, grind and soak them in water for two weeks. After this period, a pungent smell should appear, which will signal the readiness of the infusion. Such a composition should be used for watering a tomato with water in a 1: 3 ratio.

Mix one packet of dry yeast with two tablespoons of sugar and warm water. Let it brew, then use half a liter of infusion per watering can for watering tomatoes.

During flowering, use a decoction of nettle, burdock and dandelion for watering. Also, all infusions and decoctions of weeds and cut grass can be used as foliar dressings. Simply put, for spraying.

Another simple and very effective method is cow dung. It can be placed in the area between the rows of tomatoes. As it rains, all the nutrients from the manure will penetrate into the soil.

An equally effective way is chicken droppings. It must be used to prepare a solution at the rate of 250 grams per bucket of water.

An important point!

All spraying should be carried out in the evening in dry weather. Do not use highly concentrated solutions such as chicken manure in water for foliar feeding. This can lead to leaf burns.

In general, it is better to spill tomatoes with strong top dressing near the root system, rather than directly on it.

I think we answered the question: tomatoes are not tied, what to do.

Use these tips, alternating folk remedies with traditional ones, then the result will not be long in coming. Your tomatoes will produce an excellent harvest.

What to do if tomatoes are not tied? Reasons, solutions and rules of care!

Hello my dear.

Another article about my dacha life. In it, I will talk about the main reasons why tomatoes are not tied. Yesterday we collected three buckets of tomatoes, all thanks to knowledge and experience.

You will learn how to spray the bushes to increase the ovaries, how to preserve the existing ovaries and why the growth of tomatoes in tomatoes slows down.

How to feed the bushes with an excess of nitrogen. How to treat them with boric acid, yeast and ash. The importance of pollination and air temperature for good growth fruits.

As well as general rules for caring for a vegetable, so that there is a huge harvest.

Tomatoes give gardeners a lot of trouble, these vegetables come from warm regions, which means they need special care.

But despite the careful care of the plants, they are in no hurry to please the summer resident with fruit ovaries, strong and well-groomed seedlings have turned into lush bushes that do not form tomatoes.

First, you need to figure out and understand why tomatoes are not tied, what to do in this case and how to deal with the problem.

The reasons for the absence of ovaries on the bushes.

There may be several reasons, this is the unsuitable temperature for the formation of ovaries, dry air, lack of pollination, or seeds that are not viable.

Temperature conditions.

Tomatoes do not set well where the temperature regime is violated.

The comfortable temperature for the crop ranges from 20 to 25 ° C.

However, the weather in many regions of Russia presents unpleasant surprises and plants suffer.

When the night temperature drops to 12 ° C, pollen formation stops,
but the intense heat also makes the tomatoes sterile.

Experienced gardeners know what to do in order to prevent this problem:

it is enough just to choose zoned varieties and not rush to plant seedlings in the ground.

In the greenhouse.

It is easier to care for the crop in the greenhouse than in the open field.

If necessary, summer residents install heating, while frequent ventilation has a beneficial effect on the plants.

Sometimes even adherence to the temperature regime does not help to avoid failures, therefore, we will consider other reasons for the absence of embryos:

dry air;
lack of pollinating insects;
wrong choice of seeds.

Dry air.

Tomatoes are usually not tied if the greenhouse is too stuffy and humid, in which case the pollen sticks together and rolls into balls, which interferes with fertilization.

But drought also negatively affects the culture, experienced gardeners believe that the moisture content of the earth should be about 70% in order for the ovaries to form.

In order to set tomatoes faster:

do not allow the soil to dry out,
and water the beds as needed when upper layer the soil dries up.

If the bushes look juicy and healthy, do not turn yellow and stretch up, then you have nothing to worry about, but drooping and yellowing specimens need irrigation.

Lack of insects.

Sluggish tomatoes do not give ovaries, this is important to consider when planting seedlings in the garden. Sometimes sturdy plants need pollinating insects.

You can attract them to the greenhouse using sugar.
Also, do not forget to shake the twigs, thereby spreading your finger throughout the room.

Poor quality seeds.

Those plants which are grown from seeds of poor quality bloom, grow and set poorly.

Sowing material from bushes that have undergone any disease cannot be used, since such tomatoes will not bear fruit in the future.

Less often, the reason for the absence of ovaries lies in the composition of the soil, because the culture is greedy for feeding and requires a maximum of nutrients.

The right top dressing for tomatoes.

When growing a popular crop, such proven fertilizers as "Ovyaz", "Kemira" and other compounds are widely used.

Excess nitrogen.

If the plant has received too much nitrogen, it has a bright green color and a weighty vegetative mass, beautiful flowers.

But despite the beautiful appearance, the ovary will not be able to ripen due to the incorrect formation of the staminate cone, so you should not wait for the fruit.

Lack of nitrogen.

At the same time, a lack of nitrogen makes tomatoes weak and lethargic, such a plant has thin twigs, brushes are poorly developed. The component is necessary at the beginning of the growing season, when there are no fruits yet, then the bush consumes other substances.

Folk remedies will successfully replace factory fertilizers.

It is enough to dilute 1 kg of rotted mullein in a bucket of water.
It is recommended to supplement the solution with a pinch of potassium sulfate and a large spoonful of wood ash.

You need to add such a cocktail before the flowering period.

During the period of flower formation, it is useful to irrigate tomatoes with infusion of burdock, nettle, dandelion.

This dressing is harmless to plants and humans, but it should be used in moderation.

Spraying to increase the number of tomato ovaries.

Seasoned gardeners know what to do to make tomatoes better set.

Boric acid.

A well-known recipe is boric acid solution, which helps an important process and stimulates the formation of growth points of the bush, in addition, the substance increases the sugar content in fruits.

Practice proves that after flowering, spraying with boric acid in the greenhouse can multiply the crop yield by 25%.

For 10 liters of water, you should take no more than 10 g of powder and prepare the composition.

There is another trick for tomatoes, which do not set well and bear fruit in a greenhouse.

Spray plants with a mild solution of regular sugar.

B you will quickly notice the result - the pollinating insects will do everything necessary to get a lot of ovaries on the tomatoes.

Don't forget about free access fresh air, it is important for the health of the shrubs and the constant influx of pollinators.

Preservation of ovaries in tomatoes.

It is important not only to achieve fruit setting, but also to know what to do next and how to save the harvest.

It often happens that the emerging ovaries fall off, the most common reason for failure is a lack of nutrition and moisture - poor soil is devoid of minerals and other substances.

It is worth noting that young seedlings should not be irrigated with infusions made on the basis of fresh manure, nitrogen supplements and herbs.
Plants can be abundantly fertilized after the first fruit appears.

In order to prevent shedding of the ovaries.

Purchase only quality seeds appropriate for your region.
Feed the bushes in time.
And do not overheat - for this reason, most of the ovaries die.

Slowdown in the growth of tomato fruits.

Sometimes tomatoes are set successfully, but do not fill with color and develop poorly. The tops and foliage stop growing due to diseases, the culture suffers from black legs, root rot, phytophthora.

Weak plants are affected by all kinds of garden diseases, as well as a deficiency of nutritional components interferes with the normal development of fruits.

The easiest way to feed tomatoes with wood ash is to use 1 cup of the product in a full bucket of water.

If your tomatoes are set, but do not develop, use folk remedies.

eggshell saturates the soil with calcium,
and ordinary yeast combined with water is an effective fertilizer.

Some gardeners place pieces of dry mullein between the bushes, which allows them to saturate the plants with small doses of food during watering.

General rules of crop care.

If you figured out why tomatoes do not set well, try to correct the mistakes next year.

The soil.

Tomatoes prefer soil mixed with humus and compost; the soil for the culture should be loose and well heated.

Preparation for planting plants begins in the fall, when the earth is dug to a depth of 20 cm.

In spring, this procedure is repeated when frosts pass and the air temperature reaches 15 ° C.

The soil is preliminarily disinfected with an iodine solution, and also loosened well.

Hilling.

In order to strengthen the root system, tomatoes need to be spud; after the procedure, the plants acquire additional roots and absorb more moisture and nutrients.

In a greenhouse, tomato seedlings are planted in a certain direction - from east to west,

Thanks to this, the bushes receive uniform illumination and do not suffer from shade.

An increase in daylight hours helps to strengthen the ovaries, reduce the risk of their falling off and deformation. It is believed that the walls of the greenhouse are planted undersized varieties and tall tomatoes are placed next to the aisle.

Mulching.

If you plan to be absent when the tomatoes begin to set, provide them with a mulch layer.

It will maintain the necessary moisture level in the soil, transform the top of the earth into fertile soil and protect it from dry crust formation on the surface.

Stepping out.

An integral ritual of tomato gardeners is pinching the plants.

The procedure allows the bushes to direct all their forces to the development of the ovaries, first of all, this rule applies to regions where the summer is short and cool. But even in the northern region of the country, summer residents receive an excellent harvest of vegetables, observing all the rules for caring for the crop.

This is our harvest. As it ripens, we collect fruits both from the beds and in the greenhouse. We have a great harvest this year.

Follow my advice and your harvest will be just as good.

Can tomatoes be sprayed during flowering?

Even inexperienced gardeners know that it is impossible to get a good harvest without labor. As for the cultivation of tomatoes, this statement is one hundred percent true. In addition, it is important not only to make some effort, but also to do it in right time... For example, such a simple operation as spraying can be both a guarantee of an excellent harvest and irrevocably destroy the slightest hopes for it. Today we will talk about the best time to spray tomatoes and whether it can be done during flowering.

What is the best time to spray tomatoes?

First of all, let's decide why spray tomatoes at all. Spraying tomatoes, like other nightshade crops, has several goals, the first and most important of which is to protect against diseases and pests. Spraying tomatoes with solutions of antifungal drugs (both chemical and natural) can save the future crop from death as a result of late blight, a widespread and dangerous fungal disease. The first spraying against late blight is usually done soon after planting tomato seedlings in open ground or a greenhouse, choosing for this the first half of the day and dry, calm weather. In the future, spraying with folk remedies is repeated every 10-14 days until the crop is fully ripe, and spraying with chemicals is repeated in accordance with the instructions.

The second purpose of spraying is to carry out foliar dressing. By spraying nutrient solutions on tomato leaves, you can significantly harden the tomatoes and thereby increase your chances of a good harvest. For foliar dressing, you can use urea, whey, calcium nitrate, iodine, dissolving a small amount in 10 liters of water. It is best to carry out top dressing-spraying in the late afternoon, choosing clear, windless days for this.

And finally, the third purpose of spraying is to help the tomatoes form an ovary. This spraying is carried out during the flowering of the second and third tomato clusters.

How to spray tomatoes during flowering?

Let us dwell in more detail on how you can spray tomatoes during flowering and why you need it. As is known, at high temperature environment the process of ovary formation in tomatoes slows down significantly. Since we cannot create comfortable conditions for tying tomatoes, we have to go the other way - to help the pollen "germinate" by means of special spraying. Most often, a weak solution of boric acid is used for such a stimulating spraying. Getting on flowers, boric acid contributes to their pollination and the formation of an ovary, has a beneficial effect on the formation of new growth points, and also leads to an increase in the sugar content in fruits.

The recipe for a solution for spraying tomatoes during flowering is very simple: you need to dissolve 10 grams (heaped tablespoon) of boric acid in 10 liters (1 bucket) of clean, settled water. Spraying with this solution can be repeated throughout the entire flowering period of tomatoes (up to 5 sprays per season). It is best to spray tomatoes with boric acid in the early morning or evening, in clear weather without wind.

You can also spray tomatoes during flowering with vinegar, dissolving it in the following proportion: 1 tablespoon to 1 bucket of water. Acetic spraying, like boric, will promote the formation of an ovary, and will also help protect tomatoes from late blight, which is fatal for them.

Constant readers called Tamara Pavlovna Safronova from Kirovgrad and Vera Nikiforovna Korotaeva from Serov. Both are alarmed that the tomatoes in the greenhouses are blooming but not set. What's the matter? What needs to be done to make small tomatoes appear?

Many gardeners now complain about this. The reason is the long, cool spring. Yes, and in June the weather presented the tomatoes with stress: the first half of the month was cold, in the second the stifling heat began. Regardless of the weather conditions, the tomatoes began a period of active flowering. Only there are no ovaries on the plants ...

The expected harvest, most likely, will no longer be achieved, but the measures taken urgently, I hope, will help to get at least something.

Chemical treatment

Treatment of bushes with iodine solution will help the formation of ovaries. Consumption - 1 drop per 1 liter of water.
It is not difficult to prepare such a solution: add 10 g of boric acid, a drop of iodine and a little ash to a bucket of water (10 liters). Insist the mixture for a day and water the bushes with it.
Dissolve 100 g of yeast in a 10-liter bucket of water, add 2 tablespoons of sugar and let it brew for at least two days. Then the fermented mixture is diluted again - 1 glass of it goes to 10 liters of water. This "medicine" is applied under the bush.

Folk remedies

You can spray the bushes with this composition: mix a glass of skim milk with a liter of water, adding 5 drops of iodine.
Add 1 g of boric acid to a liter of hot water, cool and spray the bushes.
Sprinkle the bushes with dry ash.

Additional measures

Shake the inflorescences often to keep the pollen from clumping.
If you have a room flowering plants, put them in a greenhouse to attract pollinating insects. For these purposes, it is also recommended to sow honey plants, basil and plant marigolds in the aisles.
It is necessary to leave open all the vents and doors in the greenhouse - a draft will benefit the tomatoes.
You can treat tomatoes with the "Ovary" preparation, which is sold in specialized stores... Just keep in mind that you need to use it carefully.
During the flowering period, you can feed the tomatoes with superphosphate or nitroammophosphate: they contain an optimal set of trace elements.

Tomatoes are blooming but not tied. What to do?

Many gardeners are familiar with such a problem when tomatoes are blooming, but the ovaries are not formed, especially in greenhouses, flowers appear on the tomatoes, but the ovary is still missing. Over time, the flowers crumble, and we are no longer talking about any harvest.
What to do to tie tomatoes?
Let's try to figure it out.

No ovary on tomatoes: inappropriate temperature

In tomatoes, pollen ripens at night, and pollination occurs during the day. However, in order for the pollen to mature, it needs an optimal temperature - not lower than 15 degrees (otherwise it will not ripen) and not higher than 25 degrees. V daytime the temperature should not exceed 35 degrees, otherwise the pollen will become sterile, will not be able to germinate, and the plant will drop flowers.

What to do if tomatoes are not set in the greenhouse precisely because of the temperature? In hot weather, ventilate the greenhouse more often, leave it open overnight. You can also whitewash the roof - this will protect the planting from overheating. If the tomatoes are not tied due to low temperatures, water the tomatoes with warm water, install dark containers with water in the greenhouse - they “collect” the daytime heat well. In critical cases, you will have to install heaters.

Ovary stimulants will help tomatoes overcome the heat - traditional boric acid (1 gram per 1 liter of warm water), or the preparations Ovary, Bud, Gibbersib, Tomaton, etc.

No ovary on tomatoes: unsuitable moisture

Again - in greenhouses it is often impossible to breathe. The increased humidity leads to the fact that the pollen gets into lumps and does not have the opportunity to get enough sleep from the anthers. And because of the low humidity, pollen cannot germinate on the pistil. In the first case, airing will help, in the second - spraying tomatoes with water in the morning (it can be combined with the same Bud, boric acid or phosphoric fertilizers necessary for tomatoes during fruit setting).

Be sure to help the plant to pollinate: in the morning or in the afternoon, walk around the greenhouse and lightly shake the tomato by the stem or trellis, if the tomato is small, you can individually pollinate each plant with a brush (one tomato flower can pollinate not only itself, but other flowers as well). In calm, humid weather, this procedure can be done with open ground tomatoes.

Tomatoes are not tied? Help them pollinate

Tomatoes are not tied: they are fattening

Overfeeding tomatoes with nitrogen fertilizers creates such comfortable conditions for the plant that it forgets to think about the offspring: powerful stems, malachite foliage, and the ovaries (sometimes even flowers) are few or not. You need to create a plant stressful situation: remove unnecessary shoots and stepchildren (but not all at once, 1-2 at a time), on light soils, spill the earth once so that excess nitrogen goes to the lower layers of the earth, then stop watering for 5-7 days, remove nitrogen fertilizing and give phosphorus-potassium (ash, superphosphate, etc.)

Tomatoes are not tied: it's all about the variety / hybrid

If last year you bought a tomato hybrid (F1), got an excellent harvest, harvested seeds, grew seedlings from them, and the tomatoes bloom, but do not set - nothing strange. When re-grown, many hybrids do not produce offspring.

It may also be the inability of a particular variety to bear fruit well in your climatic conditions. For example, hybrids have already been developed that can tolerate heat over 35 degrees, and for some varieties, even 30 degrees - a critical threshold. The only thing that can be advised here is to do your own selection and grow proven varieties and hybrids.

A successfully pollinated tomato flower can be recognized by its curled petals

For what other reasons there is no ovary on tomatoes:

Certain diseases (in particular, rot)
- over-treatment of tomatoes for diseases with chemicals that affect the quality of pollen
- lack of phosphorus and potassium and "imbalances" in nutrition in general
- lack of moisture
- thickened planting, lack of light
- sharp temperature changes
- strong liming of the soil

We have considered the main reasons why there is no ovary on tomatoes and why the ovary falls off on tomatoes. Be sure to pay attention to the weather, the presence of wind, sun and help your tomatoes, spray the tomato for the ovary, make the right top dressing for the tomato in a timely manner - and you will definitely have a good harvest!

And now we invite you to watch a video on the topic - why tomatoes are not tied?

In this video, we tried to find out what is the reason for such "failures" and why this happens. By finding out the most likely reasons for the falling of flowers and fruits, and eliminating them, you can avoid these problems and, as a result, get a good harvest of delicious tomatoes.

To grow a decent crop of tomatoes will take a lot of effort and create the necessary conditions for flowering, growth and development of fruits. In order for tomatoes to bloom and form ovaries, it is necessary to cultivate a tomato in sunny open areas, follow the rules of care and feeding, take into account the temperature regime, variety, and control the pollination process.

Conditions for setting tomatoes

Creation of favorable conditions for the development of tomatoes:

the optimum humidity in the greenhouse is 50-60%;
temperature regime 21-24 C * for the formation of fruits, night temperature 17-18 C *;
watering the bushes 2 times every 6-7 days at the root;
regular loosening of the soil;
pollination of flowers;
lighting 13-15 hours;
fertilizer for the formation and development of ovaries;
mulching.

Reasons for the absence of ovaries on the bushes

Many factors affect the formation of fruits: light, soil, fertilizers, insects, humidity, air temperature.

Violation of the temperature regime in the greenhouse

Pollen production in plants occurs at night, and pollination during the day. Pollen matures at 16-24 degrees, above 28-30 degrees it becomes sterile, fertilization does not occur. At low rates of less than 15 C, the pollen does not ripen. Temperatures over 32 C are detrimental to tomatoes, they shed flower ovaries.

Even one hot day affects the formation of ovaries.

In the greenhouse, the microclimate can be controlled - warmed up at low temperatures, ventilated at high temperatures. Avoid temperature drops and jumps.

Moisture control when setting tomatoes

Mostly tomato varieties are drought tolerant, but with the appearance of flower brushes, the plant needs abundant watering. Lack of water leads to wilting of flowers.

Dry air prevents pollen from germinating on the pistil. A sign of moisture deficiency is cracking of the soil, twisted yellowed leaves, drooping tops of the bushes.

Excess moisture causes the pollen to stick together, it does not crumble. Waterlogging in the greenhouse appears after watering, if all the vents and doors are closed, the fumes remain inside, creating increased humidity. Optimum humidity for pollination is 40% - 65%. At low humidity, the bushes are sprayed with water. With an excess of moisture, the soil is mulched, the amount of watering is reduced.

Lack of insects

In open soil, tomatoes are pollinated by insects and wind. There are no bees and no air movement in the greenhouse. To attract bees, doors and windows are opened, honey aromatic plants are planted, tomatoes are sprayed with sweet liquid.

How to artificially pollinate tomatoes in a greenhouse

If the ovaries are not enough, artificial pollination is carried out:

A fan is used to scatter the pollen.
In the morning, they gently shake the flower branches, spray the air with a spray bottle so that the fallen pollen is attached to the flowers.
Using a brush, they transfer pollen from one flower to another.
Tap gently on the central stem.

The pollination procedure is carried out every 3 days. After that, the bush is watered, and the greenhouse is ventilated.

Interesting!

In pollinated flowers, the petals are bent, while in non-pollinated flowers they are closed.

Poor quality seeds

Store-bought seeds usually go through all the necessary processing. You need to buy seed from renowned manufacturers, and be sure to pay attention to the expiration date on the label. Poor quality, rotten seeds can cause disease, or not germinate at all. Seeds collected in the fall on their own should be sorted out, sorted out sick, with discoloration and signs of mold. Disinfect the rest in a weak manganese solution for 25 minutes, then rinse with water, dry on a towel.

It's all about the variety / hybrid

It happens that the purchased variety is not suitable for the region or climatic conditions... It is important to read the information on the packaging about the characteristics of the tomato variety.

In a closed building, it is better to use hybrid varieties of tomatoes marked F1 of the first reproduction. Self-pollinating hybrids take the hassle out of the greenhouse. Minus hybrid varieties- seeds collected independently are not capable of producing offspring, but if this happens, then the fruits will differ from the mother's tomatoes.

Proper feeding for tomatoes

The number of dressings for the growing season is done on average 3-4 times. Fertilize the bushes at the root and spray the funds on the plants. Foliar nutrition is produced during the formation of tomatoes. It is important to fertilize the soil before planting the seedlings in the greenhouse; humus or compost is poured in the fall, the plot is dug up (6 kg of manure per 1 square meter).

How to process tomatoes for fruit set in a greenhouse

To set inflorescences, tomato culture needs phosphorus, nitrogen, potassium. How to determine the lack of a substance in tomatoes?

Little nitrogen - yellowness appears on the lower leaves, then the rest of the leaves turn yellow.
Not enough phosphorus - purple foliage.
Lack of potassium - Brown color leaves, they dry up.

If you do not feed during flowering, the tomatoes will be sour and not ripe.

With a lack of potassium and phosphorus, superphosphate, potassium salt, potassium sulfate, potassium chloride are used. Potassium monophosphate 15 g is diluted in 9 liters of water, a bucket of solution is poured onto square meter. Mineral fertilizers should contain: calcium, boron, magnesium, iron, zinc, sulfur.

They often opt for organic fertilizers. Organic matter promotes the development of bushes, the formation of flowers, protects against many diseases, and has no chemical components.

Root dressing

When the first flower brushes appear, the tomatoes are watered with a solution:

take 20 g of potassium per bucket of water;
add 20 g of superphosphate;
mix;
one plant accounts for 0.5 l of solution.

Yeast mixture:

fresh yeast 100 g is diluted in 1 liter of water;
add 9 liters of liquid;
stir;
water this mixture on 13-15 bushes.

Ash contains minerals and trace elements necessary for the formation of ovaries in tomatoes. Once a week, a spoonful of ash is poured under each plant or a solution is used: a spoonful of wood ash in 8 liters of water. Twice a month, 1.5 liters of nutrient fluid is poured onto one bush.

The iodine mixture strengthens the immunity of tomatoes during the formation of fruits:

sift ash 3 liters;
combined with 5 liters of hot water;
insist 60 minutes;
diluted with 9 liters of warm water;
iodine is poured in 10 ml;
boric acid is added 10 g;
the mixture is stirred, left for 24 hours;
the resulting solution of 1 l is diluted with a bucket of water;
watered at the root of each plant with 1.2 liters of the mixture.

The iodine solution is added during the period of laying the brush:

3-4 drops of iodine are dripped into 10 liters of warm liquid;
stir;
pour 1 liter of solution under the bush into moist soil.

The herbal mixture is prepared for 2 weeks:

take 5 buckets of grass;
8-9 liters of mullein;
1 kg of ash;
150 g yeast;
1.5 liters of whey;
200 liters of water;
stir the mass, leave to infuse for 14-16 days;
a liter of the mixture is poured onto one tomato bush;
before feeding the plants are watered with water.

Ash or iodine solution is used for foliar feeding:

In 2 liters of water, 200 g of ash are diluted, it is pre-sieved. Boil the mixture for 20 minutes, add a bucket of water, grated household soap 100 g. A day later, the plants are sprayed with the solution. The buds love this kind of feeding and are actively blooming.
A liter of milk, 25 drops of iodine, a spoonful of hydrogen peroxide are diluted in 10 liters of water, everything is mixed. 0.5 l of the mixture is poured onto one bush once a week.

In the cold time of the day, it is not recommended to fertilize the bushes, nutrients are poorly absorbed.

What to do if the plant is overfed with fertilizers

An oversupply of fertilizer results in lush greenery and lack of ovaries. Measures to eliminate excess soil nutrients:

ash is brought in - 90 g is poured under the bush;
temporarily do not remove shoots from plants, excess fertilizer will be used for their growth;
sawdust is added to the ground, they absorb nitrogen - the result is only after 25-35 days;
the beds are watered abundantly - a bucket of water per bush, the excess nitrogen will be washed out, but often it is impossible to water, a fungus will appear;
so that the plants begin to bear fruit, they cut off 2-3 lower leaves and 2 leaves at the top of the bush, stress pushes the tomatoes to form fruit.

Complex additives are used at temperatures above 16 degrees, otherwise the substances will not benefit the plants, but in a large number stay in the ground.

Spraying to increase the number of tomato ovaries

Boric acid

Boron normalizes nitrogen synthesis, improves metabolism, increases chlorophyll in foliage, makes tomatoes sweet and juicy. For the formation of flowers and ovaries, vegetables are sprayed with boric acid.

Solution preparation: 3 g of acid for 3 liters of hot water. Greens are sprayed with the cooled agent - a liter of the product is used for 10 squares of the plot. Copper can be added to the solution. The earlier you start spraying, the faster the ovaries will appear. The first treatment is done at the beginning of flowering, the second - during the period of intense color.

Spraying rules:

use a warm liquid for the solution;
the solution should not fall on the top of the plants;
processing is carried out through a spray;
spray only on brushes and flowers.

Tomatoes are fattening

Signs of fattening tomatoes - the tops are growing, the rapid growth of shoots, the large leaves are curled, the ovaries are not formed. The plant develops a weak flower brush with few colors. Fatting often occurs in indeterminate tomato species, and hybrids with a long flower cluster.

The main reasons for fattening tomatoes:

The growth of green mass occurs due to an excess of nitrogen in the soil. Until all the nitrogen has been used up, no ovaries are expected.
With frequent watering, air humidity increases.
Low light, short daylight hours.
Dense planting of seedlings.
Frequent and abundant feeding during the growth of the bushes.

If the bushes continue to grow, they take agricultural techniques:

pinch the upper brush, leaving 5-6 well-developed ovaries;
provide tomatoes additional lighting, extend the day to 15-16 hours;
in cold air in the greenhouse, the temperature is raised to 24 degrees;
you need to thin out the dense planting of plantings;
part of the foliage is cut off (1 leaf every 2 days);
stop watering the bushes for a week;
air the greenhouse daily;
feed tomatoes with phosphorus, magnesium, potassium;
nitrogen is excluded for a while;
shake the plants to pollinate the flowers.

Nitrogen

Nitrogen supplementation is essential for the proper development and growth of tomatoes, however, overfeeding the plants leads to the loss of ovaries.

There are 5 groups of nitrogen fertilizers:

Ammoic - ammonium chloride and sulfate.
Nitrate - sodium and calcium nitrate.
Ammonium nitrate.
Amide - urea.
Liquid ammonia.

Cold dense soil, inclement weather with temperature changes, lack of water, poor metabolism - all these factors affect the absorption of nitrogen by plants. Its deficiency is often found on sandy loam and light soils.

Excess nitrogen

A large, sprawling bush with beautiful green foliage without ovaries is a sign of excess nitrogen. It is needed at the beginning of the growing season, when the seedlings are just starting to grow and after the formation of fruits.

Warm water helps to quickly remove excess nitrogen fertilizers from the soil, but often this cannot be done, the plants can rot. The sawdust takes up some of the nitrogen and thus saves the crop. An assistant in this situation will be an ash solution.

Lack of nitrogen

With a lack of nitrogen, irrigation with organic fertilizers is carried out 3-4 times per season. A sign of a lack of organic matter is the light green color of the leaves, they are twisted, the leaf blade is dull, turns yellow over time. The stalk is short, fragile, the ovaries fall off early.

Solution No. 1: for 30 liters of water, 1.4 kg of mullein, 2.5 tablespoons of nitrophosphate. For one bush 0.5 l of the mixture.

Solution No. 2: dilute 1 kg of poultry manure, 2 tablespoons of superphosphate and potassium sulfate in 20 liters of water. One plant - 0.5 liters of substance.

Can be used ammonium nitrate and urea. Complex additives are used to enrich the soil with nitrogen: Solution, Universal, Kemira, Effekton.

Attention!

Nitrogen is applied less than potash and phosphorus fertilizers.

Measures for the tomatoes to set

Regulation of the development of tomatoes in the greenhouse:

with the help of temperature - after sunset it is raised, during the heat they ventilate the greenhouse;
with the help of air humidity - plants are sprayed, containers with water are left in the greenhouse;
increasing the concentration of carbon dioxide in the greenhouse helps to increase the number of inflorescences - open barrels of manure or compost are used;
removal of weak ovaries, foliage, side shoots;
the branches of the plant can be turned towards the sun by securing them with spacers.

Formation of a bush for tying tomato fruits

Uncontrolled growth of shoots leads to dense greenery, all the plant's strength goes to them, and not to the ovary. It is important to form bushes for neat beds and a rich harvest.

The first time the stepchildren are pruned 15-16 days after planting the seedlings. A lateral shoot appears in the leaf axils, it is removed with a pruner, leaving 1 cm long. Passion-picking is carried out in the morning, in sunny weather. Pruning is done every 10-12 days. The length of the stepson before cutting should not exceed 6 cm. The stem of tomatoes grows throughout the growing season. Low varieties of tomatoes do not require pinching and are not prone to rapid growth.

Have high grades tomatoes leave only one central stem. Up to 6-7 brushes with tomatoes are formed on it. In medium and low-growing tomato species, 2-3 shoots are left.

No more than 5-6 brushes are left on each stem, the rest are removed. To stop the growth of the bush, pinch the tops so that 2-3 leaves remain above the last brush.

Tall bushes are tied to trellises or supports. Removing the lower leaves promotes the formation of ovaries and serves as protection against fungal diseases.
