Often gardeners complain - there are no cucumbers, only barren flowers. What to do in this case? What is the reason for the continuous flowering of plants with barren flowers alone? And are they needed at all, these empty flowers?
First of all, a significant delay in the appearance of female flowers and late fruiting lies in the quality of seeds. If you did not listen to the numerous recommendations and sowed fresh seeds, then the plants grown from them form first male flowers - empty flowers, and then - female ones. A completely different picture if you sowed seeds 2-3 years ago. In this case, female flowers are formed simultaneously with male or earlier than male.
But what if your seeds are fresh, or you do not know the statute of limitations of the purchased seeds? This is easy to do - they need to be warmed up, and plants from such seeds will produce female flowers much earlier than usual. Presowing hardening of seeds with negative or variable temperatures will also accelerate the appearance of female flowers.
Another reason for the infertility of cucumbers is a nutritional imbalance, most often an abundance of nitrogen fertilizers in the soil, which causes the rapid growth of lashes, leaves and barren flowers. In this case, it is very useful for plants to feed with fast-acting phosphorus fertilizers, for example, superphosphate extract (2 tablespoons per 10 liters of hot water) or an infusion of ordinary wood ash.
The third reason for the delay in the appearance of female flowers is watering the plants with cold water. The water temperature must be at least 25°C. Water should not be allowed to be colder than soil.
The next reason for "barren abundance" is a large excess of moisture in the soil. Dry the soil on the cucumber bed for a few days. As soon as the leaves on the plants slightly wilt, an abundance of female flowers will immediately appear. But at the same time - do not dry out the soil.
About proper care - in the article Cucumber care.
The high ambient temperature, the strong thickening of plants in the greenhouse, etc., also have a serious effect on "barren abundance".
And if all this does not help, then pinch the top of the main stem of the plants. It will stop the growth of plants in length, cause the growth of side shoots and female flowers.
And what about empty flowers? Some gardeners remove most barren flowers in the mistaken belief that this will encourage female flowers to grow. There is no benefit from their removal, and it is really possible to worsen the conditions for pollination of female flowers. Empty flowers on the plant themselves will quickly turn yellow and fall off.
In recent years, the most popular are bunch varieties and hybrids of cucumbers, especially the female type of flowering, which are distinguished by high yields and generally good pickling qualities. They form in a knot from 3 to 7 ovaries. But not every gardener manages to get fruits from these ovaries.
This is a fairly common occurrence, especially in hot weather and in film greenhouses. At the same time, part of the ovaries does not grow and gradually begins to turn yellow, and then quickly dries up and disappears. What's the matter? There are several reasons for this phenomenon:
- too high air temperature in the greenhouse (over 35 ° C).
- very high relative humidity (over 90%).
- in varieties and hybrids of a purely female type of flowering, the absence of pollinating insects due to prolonged cool weather or the absence of male flowers (barren flowers). Up to 10% of cucumbers of any pollinating variety must be sown to them.
- very rare collection of cucumbers. Collect them daily or, in extreme cases, every other day. Overgrown fruits hold back the pouring of new ovaries.
- a significant lack of nutrition in the soil. Modern tuft-bearing hybrids require a much higher and more uniform nutrient content in the soil. There is simply not enough nutrition for the growth of all the ovaries in the bundle. At the same time, 1-2 fruits grow, and the rest dry up and fall off. Therefore, if there are a lot of ovaries on plants, they should be fed every week with small doses of mullein infusion with the addition of urea to it.
And in order to improve the filling of the ovaries, especially in cool weather, it is necessary to carry out foliar feeding of plants with Zircon or Epin preparations, which increase the resistance of plants to stressful situations.

Cucumber care in the open field from planting to harvest
Basic rules for caring for cucumbers
It does not matter which method of planting cucumbers was chosen: seedlings or seeds. Plant care includes the same main points:
- Moisturizing, watering cucumbers. Water is the most important ingredient in caring for a plant. Depending on how well the cucumbers were moistened, one can judge what the crop will be like. The danger of open ground is that with insufficient watering, especially on hot days, the crop can produce bitter fruits. When visually inspected, dry land serves as a small bell about the need for moisture. In addition, do not forget that in colder, rainy weather, watering should be tied up or reduced to a minimum, otherwise it is fraught with the death of the plant, from an excess of water, the roots will simply begin to rot. Young cucumbers are watered with less water, but more often. While grown, adult plants are watered quite plentifully, but less often. In this case, it is necessary to know the measure, the main task is to moisten the whole earth with water.
- Top dressing with mineral and organic fertilizers. Feeding the plant with additional substances makes cucumbers stronger and more resistant, reduces the likelihood of disease and crop loss. Usually about six dressings are done in one season.
- Loosening the earth. Manipulation is performed every time after the next watering or after it rains. This is done as carefully as possible so as not to inadvertently damage the roots, which are located close enough to the surface.
- Protection of cucumbers from the destructive properties of the environment, diseases and weeds.
Each item is important individually, but only in a complex care can give a good result. After all, it is important not only how to water, but how and when to feed and loosen the soil.
Growing cucumbers outdoors
If you need to speed up the harvest, you should try growing cucumber seedlings. The variety of varieties that grow well in the garden will allow each summer resident to choose exactly what they like.
In order to have a good harvest every year, new seeds must be used for the next season. An important step before planting is the selection of seeds. For this purpose, you need to pour liquid into any vessel and add five grams of salt. Seeds are poured into this solution and after a while all unnecessary, empty achenes will emerge.
After selection, disinfection is carried out. To create a solution, potassium permanganate and water are needed. The calculation is usually as follows: 1 mg of the drug per 100 ml of water. Seeds are immersed for about half an hour. And then washed under running water.
The next step is germination. The seeds of the plant are placed in a slightly damp cloth, kept in it for three days at a temperature of 25-30 ° C. Before planting in open ground, the seeds must be hardened. To do this, they are placed in the refrigerator, on average, for a day and a half. Then you can sow.
If initially the seedlings are grown at home, then you need to prepare an individual pot for each plant, into which a mixture of useful substances is poured: peat, earth, sawdust and humus in equal proportions. Seeds are planted to a depth of about one and a half centimeters and covered with a plastic bag on top.
Warm water is used for irrigation and seeds are kept at a temperature of 27 ° C. The temperature gradually decreases, weak shoots are cut off, and not pulled out, so as not to damage the root system of stronger ones.
If necessary, land is added, fertilizing is carried out (no more than two times). In this case, the hardening of the plant is carried out seven days before the start of planting. To do this, the temperature is reduced to 16 ° C.
How to transplant cucumbers
First of all, holes are prepared in the open ground. The required distance is 30 cm between plants and 50 cm between rows. Pits must be poured with a solution of potassium permanganate: 1.5 grams of potassium permanganate per 10 liters of water. Seedlings from pots are transplanted into a hole, watered, a little dry earth is poured on top. If the seedlings were planted in plastic or other containers, you need to get a plant with an earthen clod and plant it in a hole.
To get more yield, cucumbers, as they grow, must be tied up on a trellis. The first weeks after transplantation, frequent loosening of the earth should be carried out, shallow and accurate. Do not forget about top dressing and weeding from weeds.
Why is cucumber bitter and crooked
The harvest does not always turn out the way you expect. Frequent dissatisfaction arises when cucumbers, for some reason, grow bitter and crooked. This happens not just like that and the cause cannot be one circumstance - it is a complex of factors.
- Landing. The use of poor-quality seeds, non-compliance with the rules of planting, lead to crop failure.
- Bad watering. Dry land will not allow you to grow good, quality fruits, it only slows down growth. Because of this reason, cucumbers can give a bitter taste.
- Underfeeding or overfeeding. In both cases, nothing good will come of it. With underfeeding, there is a chance of losing some of the crop, and overfeeding is fraught with bitterness and pretentious forms.
- Collection of fruits. Even such a manipulation must be done on time, because ripe cucumbers interfere with the growth of the rest.
Cucumbers do not bear fruit
The main reason why cucumbers do not bear fruit is plant diseases. More often, these are fungal diseases. For example, root rot, which affects the root system and manifests itself in the fact that the leaves of cucumbers first wither, become covered with brown spots, and then the plants die. To prevent this disease, it is necessary to carry out disinfection of the soil.
The reason why the leaves of cucumbers turn yellow can be an aphid - an insect that causes the plant to turn yellow and dry. As a preventive measure - timely weeding. White leaves on cucumbers can be caused by spider mites. Affected leaves are collected in a bucket, burned and buried. To prevent the spider mite from appearing, it is necessary to carry out thorough weeding from weeds and plant cucumbers in the early stages.
Another reason for the lack of fruit can be a barren flower. These are male flowers of cucumbers, while in order for the plant to begin to bear fruit, female ones are needed. You can correct the situation by pinching. The method consists in cutting off the top of the cucumber above the sixth leaf. The plant is left with three shoots, the rest is removed.
You can also resort to pinching. Stepchildren are called unnecessary sprouts that draw all the strength from cucumbers, and they cannot bear fruit. To carry out the manipulation, you need to remove the side shoots, the first 5 leaves and the ovaries in the axils, the first 4 leaves.
In order for the plant not to hurt, you need to follow a couple of simple rules:
- before planting the seeds, you need to disinfect them;
- water cucumbers with warm or summer water;
- carry out feeding with fertilizers;
- weed the beds, ridding them of weeds;
- keep in mind the temperature and humidity levels.

Cucumbers do not produce fruit-bearing flowers. What should be done to form ovaries?
Hedgehog
if the cucumbers are bee-pollinated, then pinch the stem over the fifth leaf. . lateral shoots will go, and female flowers with ovaries will grow on them. . if this is not done, the cucumbers will still be, but fruiting will be delayed for 2 weeks
Elena Mango
It depends on the variety and seeds. Fresh seeds give few ovaries. Try to smoke in a cucumber greenhouse.
Nadena
feed them I'm sorry manure
Ekaterina Rodina
Try pollinating by hand, suddenly because of this. Wrap the cotton wool on the match and carefully about the queue for all the flowers
Tatiana Bochkareva
If cucumbers are not self-pollinating, take an ear cleaning stick and gently touch the pistils from flower to flower, that is, artificially pollinate
FAQ FAQ
That is, there are no female flowers, wait for them to appear. There are predominantly female flowering varieties, so I couldn't wait for the male flowers to pollinate the females first. Then there is just enough and the insects work
Nadezhda Kotsareva
Where did you get the seeds and what kind? Pinching the top can help so that the ovaries go on the side lashes.
Lydia
I have the same problem this year. last year's seeds.
I had to search and found three-year-old seeds in my boxes and annoyed me.
Zhenechka =)
well, women will still be there, the only question is time :) And at the expense of speeding up, this is really pinching the top, because I also have a cucumber on the window with a bunch of male flowers, only two female ones gave the main shoot, and when the side ones climbed - there are a lot more women. But for now, the ovaries practically do not increase ... What did you feed them with last year? Did the fruits grow well?
Taisia
Obviously, you grow varietal cucumbers, not hybrids. In varietals, male flowers grow on the central stem, without an ovary, and female flowers grow on lateral shoots. Therefore, varietals (without F1) are pinched during growth over 5-6 leaves so that side shoots begin to grow. , and cucumbers on them. In old seeds or well-warmed up before planting new ones, more female flowers are formed.
Gulya
You have male flowers blooming, which almost always bloom before the female! Male flowers are only for pollination, but only female flowers give ovaries!!! !
If this happens, then the plant needs to be stressed! Each plant in adverse conditions tries its best to continue its kind and begins to bear fruit!
Try to dry the cucumbers, do not water them until the leaves wilt. After that, give abundant watering and you will see, the plants will begin to throw out female flowers with ovaries !!! !
In general, it’s better not to skimp on good hybrids that have a predominantly female type of flowering!
A common story is that they planted cucumbers, the seeds are good, the varieties were picked up and they wanted to get a crop of cucumbers early, but they are still not there. Scourges of cucumbers are good green, but there are no cucumbers, what is the reason? Plants bloom profusely, but ovaries do not form, there are several reasons for this. Empty flowers, which are abundant on cucumber bushes, are male flowers and without them it is impossible to get an ovary. Therefore, the mistake of gardeners is that they begin to pick off barren flowers, this will not help to get more ovaries. Several factors influence the number of male and female flowers, such as varietal characteristics, seed quality, and growing conditions for cucumber plants.
A feature of the flowering of cucumbers is that only male flowers appear first on the main stem of cucumbers, and then male and female alternately form. To the top of the main stem, the number of female flowers becomes predominant, less often male flowers (barren flowers) predominate. Therefore, gardeners often cannot wait for the first cucumbers for a long time, it seems that they began to bloom a long time ago, but there are no ovaries.
Cucumbers are very demanding on light, in shaded places they form female flowers poorly, shading can be caused by too dense planting, they shade each other. Intense heat and waterlogging of the soil, imbalance of fertilizer application, with a predominance of nitrogen. All these reasons can be the predominance of empty flowers on cucumbers over female flowers and, as a result, a decrease in yield.
If you yourself collected cucumber seeds, then before sowing them, they need to be heat treated. To do this, the seeds must be placed in a fabric bag and hung over a radiator, let them hang there from the beginning of winter for 2.5-3.0 months, this will age the seeds and increase their yield.
You can increase the formation of ovaries on cucumbers by applying organic fertilizers with the addition of superphosphate before planting in the hole.
If, nevertheless, a lot of empty flowers appear, it is necessary to pinch the top of the main stem, which will lead to the growth of side shoots, on which more female flowers form.
Irrigation with cold water can cause a delay in the appearance of female flowers on cucumbers, this is especially important in the first time after germination and growth. Water must be poured into containers and barrels so that it warms up, or mixed with hot water, bringing the water temperature to 25 degrees. If the garden is small and planting cucumbers does not take up much space, this can be done. It is better to water in the afternoon, when the water in the container and the soil warm up. However, it should not be watered too late in the evening, it is harmful to plants.
There is one peculiarity in growing cucumbers, which allows you to achieve maximum yield from the bush. Cucumbers are very fond of moisture, but do not like flooding. Good watering is necessary for cucumbers in the first period of growth and during the growth of fruits. But during flowering, cucumbers need to arrange "unloading" days, that is, stop watering for several days, drying the soil, this will stimulate the appearance of more female flowers. When the ovaries appear, watering must be resumed. In hot weather, cucumbers should be watered every day and even twice a day; in cloudy weather, watering should be refrained from.
Your task is to organize drip irrigation for each bush, which will provide the cucumber bush with the necessary moisture for a long period. You say - it is difficult, and expensive. And here it is not. For example, I put a 1.5 liter bottle of water under each bush, and pierced a tiny hole at the bottom of the bottle with an awl. Thus, 1.5 liters of water escapes me per day. All this water is received by the cucumber bush, it does not evaporate and does not flow out.
These are all the reasons for the low fruiting of cucumbers and ways to restore it.
Have a good harvest, friends!

Tell me which varieties of cucumbers bear fruit better in a booth
✿Elena m✿
There is a wide variety of varieties, but experienced gardeners recommend growing cucumbers from domestic selection, and those that are common and adapted to your area.
Cucumbers "Vyaznikovsky-37". An ancient Russian variety, which is an early variety of cucumbers (up to 50 days pass from germination to fruiting). Elongated ovary - up to 10 centimeters. The variety is inherently universal. Suitable for salads and for pickling. Open ground preferred.
Cucumbers "Competitor". The variety is early, fruitful, pickling. The taste quality is good. Cucumber is resistant to powdery mildew and bacterial spot. A fruit weighing up to 120-130 grams, from germination to fruiting, the growth period takes about 50-55 days. Suitable for both greenhouses and open ground.
Cucumbers "Bush". Productive and early maturing variety. Plants have a bushy form. Excellent quality of taste. Suitable for use in conservation, the fruits themselves weighing up to 120 grams. Before fruiting from seedlings, the period takes up to 55 days, suitable for growing in open ground.
Cucumbers "Zozulya". Early variety. Parthenocarpic, however, in order for fruit formation to be better, pollination is advisable in the first month of fruiting. From germination to fruiting, a period of approximately 48 days passes. This variety is more than moderately susceptible to root and white rot. Weaving is weak, the main whip has an average length. The leaves are medium in size, green, have a rounded pentagonal shape. The ovary has a cylindrical shape with a slightly furrowed surface. Pubescence white, complex, rare. Zelenets has a cylindrical shape with a slightly tuberous surface. Zelentsa has a smooth base, with a rare arrangement of tubercles. The fruit is round-triangular in cross section. The length of the cucumber is up to 23 centimeters, weight - up to 290 grams. Fresh fruits have good taste qualities. Serious advantages of the variety: friendly and early fruiting. This variety was approved for use in 1977. It is recommended to grow in spring film greenhouses.
Cucumbers "F1 Moravian gherkin" Mid-season variety, bee pollinated hybrid suitable for open ground and greenhouses. The fruit is small 8-10 cm, not bitter. This variety is universal and suitable fresh, and for pickling and canning.
Cucumbers "F1 Connie" Early ripe variety, abundant harvest, parthenocarpic hybrid. The plant produces an average number of lashes, with bunch formation of ovaries. The fruit is cylindrical, white-spiked, not bitter. Very resistant to major cucumber diseases. Universal grade.
Cucumbers "F1 Masha" Parthenocarpic, the earliest hybrid. The fruits are medium, 8-11 cm long. The variety is universally suitable both fresh and for pickling and canning. The hybrid is resistant to cucumber mosaic viruses, cladosporiosis, and powdery mildew. Suitable for both greenhouses and open ground.
Cucumbers "F1 New Nezhinsky" Bee-pollinated hybrid, early ripening, pickling and quite productive. The fruit is 8-10 cm long, without bitterness. One of the best varieties for pickling. Plants are long. Suitable for both greenhouses and open ground.

Why do cucumbers bloom profusely in a greenhouse, but bear little fruit?
What is missing cucumbers in the greenhouse? There are a lot of flowers and ovaries, but there are almost no cucumbers. The ovaries turn yellow and rot.
Aleks55
In fact, there are many reasons for this problem. The first and probably the most popular is that you do not have self-pollinating cucumbers and insects cannot pollinate cucumbers. If this is the case, then you can try to attract the bees with the help of sugar syrup or by hand forgive.
Perhaps there are too many ovaries on one plant and the plant can not cope. There should be no more than 20 ovaries.
Perhaps this is the wrong watering, since cucumbers are sensitive to watering: they should not be watered too much and the soil should be allowed to be dry. Also, you need to water only with warm water.
The most unpleasant thing is that there is a possibility that your cucumbers have become ill with bacteriosis. They become infected with bacteriosis mainly when temperature fluctuations, high humidity, thickening of plants. In this case, it is necessary to use Bordeaux liquid.
polygraph
The problem is well known. I myself grow cucumbers in a polycarbonate greenhouse. And I also encountered this. There are many ovaries, but few cucumbers. Studying this nuisance, I read a lot of literature. And here are the reasons. Cucumbers are very sensitive to temperature changes. If the temperature is low at night and hot during the day, cucumbers get sick. The difference can be no more than 6 degrees. Cucumbers also love watering with warm water, and waterlogging or drying out is also detrimental. There is another reason - the lack of trace elements. For example potassium and phosphorus. Nutrition needs to be replenished. The formation of the plant is also the cause of the death of the ovaries. If there are a lot of male ones, then you need to pinch them so that the female ovaries go. But you need to know what varieties and what year. And, of course, pollination. All problems are solvable, you just need to carefully look at the plants and solve problems in a timely manner, then there will be cucumbers.
Galina Skulkina
In order not to depend on insects, self-pollinating hybrids are usually planted in the greenhouse. And the absence of an ovary with abundant flowering indicates that, most likely, mainly male flowers bloom. Perhaps the bush is not formed correctly, because the cucumbers in the greenhouse do not pinch along the main stem, like ground ones, because it is on them that the female flowers are located, and the male ones appear from the side shoots. They must be pinched after the sixth sheet.
The second reason may lie in too abundant watering. It is necessary to stop watering for three or four days. Mulch the bed with a thick layer of fresh grass. Watering resume with warm water. Don't forget to rain.
persona grata
If you are growing cucumbers that need pollination, then the previous answer indicated a possible reason why fruits are not formed - pollinators are missing. In this situation, you can work as a "bee" yourself and pollinate the flowers, or open a greenhouse to provide pollinating insects with access to the flowers. If you grow parthenocarpic varieties (self-pollinated), then the reason may be a lack of nutrition, too high a temperature.
It is best to plant several different varieties, under equal conditions they can give a different yield, and if the conditions for one variety are not very suitable, then others will be able to compensate for this deficiency.
dolphanics
If the bee cannot enter the greenhouse, then pollination will not occur. There are many flowers, but no fruits. And another reason for the temperature. Now hybrid varieties are very popular, and in them at an air temperature of plus 35 degrees, the pollen becomes sterile. The bond dries up.
Another reason is the unexpected cold snap. If the temperature suddenly drops below fifteen degrees, then the plant stops growing and developing.
And pay attention to the following reasons for poor ovary
There may be a lack of moisture or vice versa, too much moisture, irregular watering of plants, an overabundance of fertilizers, or the planting material was not quite suitable
Pro100th
The ovaries of cucumbers turn yellow and rot, or there is no proper access to the plants for bees, or there may still be too moist soil and air, which causes plant disease - bacteriosis. Maybe the plants are too close together.
Watch the air temperature, too sharp a drop in it can also affect, the lack of trace elements can be another reason.
As well as improper development of plants, this is to pinch extra shoots (they should not be too long and there should not be too many of them either)
It is necessary to change the place for planting cucumbers, observe the watering time in the heat early in the morning or in the evening
Andrey0817
Lack of pollination of flowers. In order for the ovary of a cucumber to appear, a flower needs pollination. This work is done by the bees and the wind. If you plant cucumbers in a greenhouse during the cold season, when bees are not yet flying, then you need to choose self-pollinating varieties of cucumbers - they do not need pollination.
elena-kh
Pollination is most likely the problem. Probably, insects that would pollinate your cucumbers do not get into your greenhouse. You can do it yourself with your fingers. I did this when I grew cucumbers and other crops on my windowsill.
Tata all red
Perhaps you have planted a variety of cucumbers that are not capable of self-pollination. Therefore, in order for the cucumbers to start, they must be artificially pollinated. Now the stores are full of such funds. As a rule, they are called "ovary".
orchideaua
The answer is quite simple - they do not pollinate. There is no access to pollinating insects in the greenhouse. Open the greenhouse at least once a day and place saucers with fragrant syrup between the rows of cucumbers.
haleron
Well, it's quite simple. In the greenhouse, they develop well and they have all the conditions for this. A greenhouse is primarily a closed area where there is no access to insects that can produce pollination.

what to do if apple trees do not bear fruit?
darina freestyle
I completely agree with Ivan Molchanov, the so-called highly rejuvenating pruning of apple trees makes them bear fruit. All branches extending from the trunk at an acute angle must be removed. You can also hang loads on the branches so that they grow almost in a horizontal position. I read about the variety "Lobo" that even with the correct formation of the crown, after five years, forced pruning is done. There were some other varieties listed, I don’t remember the rest.
Grishanov Alexander
At least wait until spring.
Vitoldos
Plant something that will be known to bear fruit.
Ivan Molchonov
give a reamer and a pruner to the hands of professionals === proper pruning of trees works wonders
Lilia Nemykina
pruned well in early spring
Alexey Losev
Probably have to buy apples in the store
LANA
There is an old belief .... The apple tree must be "scared" i.e. not to say that you will cut it down if it does not want to bear fruit and the like (only without laughter). To be sure, you need to come up with an ax and leave it near her for a while! I tried it myself .... and I "talked" to her in the summer, and in the fall flowers appeared on her !!?? Before that, she sat for 9 years and nothing .... But the next year, in the spring, there was just a cloud of flowers, and not an apple tree!? Apples, about 2 buckets were removed .... not bad for the first time!? So .... believe it or not !!!
Kostya Tereshchenko
uproot her
vladimir
If the vaccine was from a top shoot, then the apple tree may not bear fruit for 20 years. You are on February 15 (Candlemas)
go to this apple tree and scold it or threaten it. Helps.
Flute
If less than 10 years, then do nothing! You obviously have no wild! Wait! You need to feed the apple tree with either ash or complex fertilizer! - landing error - deepened! Although I myself deepen by 20 cm - from mice! Later a year, but otherwise even better! They bloom in three years! Write in detail what is happening with you and where the garden is! How to plant - pit, filling, position of the seedling, watering, soil!
Toffee
I agree with LANOY: there are signs and beliefs. Here about an ax, but you can lightly drive a nail ... Checked.
HEIGHT
Scare, how it is not funny and naive, BUT WORKS!
Dewdrop
the ovary is formed on branches growing horizontally, all branches growing upwards (if there are many) must be cut
Maria
That's right, SCARE, but words do not help much, Drive a nail into the trunk (this is useful for apple trees) and promise to cut it down if it does not begin to bear fruit. Checked on my apple trees
Anna Malchikova
I agree with Sergey, my neighbors did this, it helped! I'm talking about a nail, only a big one is needed.
tatyana savchenko SIBERIA
This year, for the first time in my life, I prune an apple tree - the previous owners assured me that it was a standard tree, but it seemed to me that it was still creeping. I decided and removed one of the central branches, a very large one, almost a trunk (I don’t know why, but this apple tree has several central branches) and 3-4 more smaller ones growing vertically on skeletal branches. She was just stunned by the result. The apple tree, which practically did not bear fruit (5-8 apples is not a harvest), gave 2 large buckets (also not yet, it should give more). This year I will cut out another central branch and several smaller ones. Unfortunately, full pruning of apple trees cannot be done immediately, so there will be work left for next year.
Efim Vladimir Zelenkov
What is missing and what should be looked for.
1, drive in a nail - lack of iron.
2. It’s good if you root it with garden kemira.
From personal experience. Leningrad region. Pear, fifteen years old and never bloomed.
1. There was a lot of lichen on the bark. I shot this lichen with a korchetka.
2. I made a solution of copper sulfate, smeared the barrel with a brush.
Fifteen years later, it bloomed for the first time, but there were no fruits, everything was thrown off. The next year, he repeated the operation. There were a few pears
I repeated the operation again. More than ten buckets of pears.
You have to look for what is missing.

As the great agronomist of the early 20th century Ovsinsky wrote, a plant bears fruit only when it feels the need for reproduction. That is, when he feels bad, well, at least uncomfortable. Then it strives not to build up "muscle mass", but to give out fruits, i.e. seeds, in order to, having died, give a new life. This explains the riot of flowers in the desert in spring. The task of man is to maintain a balance between comfort and difficult conditions. This is done differently for different plants, for example, cucumbers and tomatoes are planted in two-line beds with a distance between lines of 40-50 cm, and between plants 25-30 cm, but between beds 1 m. Grapes are trimmed, pome fruits are trimmed and bent down. Driving nails - from the same row.
