Zucchini do not bear fruit what to do. Why don't zucchini tie? What to do in this case? Ways to solve the problem

Zucchini is considered an unpretentious crop that is quite easy to grow at home. However, despite this, sometimes problems arise when growing this vegetable. Therefore, some are interested in why zucchini may not grow. Often the growth rate of bushes is affected by temperature, as they instantly react to its change. For example, at high temperatures, squash bushes grow, but the fruits do not set.

Inexperienced vegetable growers do not know what to do when zucchini grow poorly. To understand this, you need to familiarize yourself with the main causes of dysplasia of squash bushes. There are eight main reasons why zucchini grows slowly.

1. Gone are the insects

Often the fruits do not appear due to the lack of insects that should pollinate the flowers. Without timely pollination, ovaries will not appear on the bushes and zucchini will not begin to bear fruit.

What to do if the zucchini in the garden does not grow fruits? In this case, you will have to deal with the pollination of flowers yourself. To do this, you will have to pick several male flowers with stamens from the bushes. It is with their help that pollination of female flowers will be carried out. However, before that, you should learn to distinguish female flowers from male ones. There are two guidelines to help you do this:

Male flowers appear much earlier than female ones.
The female flowers have a seal in the lower part, while the male flowers are located on a thin stalk.

It is better to pollinate one female flower with two male ones, so that pollination is sure to be successful. Upon successful completion of the process, fruits will appear on the bushes in 5–7 days. If they are not, you will have to repeat the procedure.

Some do not want to independently pollinate plants and attract insects to the flowers. To do this, they spray the bushes with syrup made from honey. During spraying, the leaves are pushed apart on the plants so that more honey liquid gets on the flowers.

2. Something is missing

Another reason why zucchini grow, but no fruit is set, is the insufficient amount of fertilizer in the soil. In order to avoid a problem with a lack of top dressing, organic and mineral fertilizers should be regularly applied to the soil.

Top dressing is carried out at least three times per season:

The first is carried out before flowering, a week after the appearance of the first shoots. Organic fertilizers and preparations such as Effecton or Agricol are added to the soil.
The second is carried out at the time of flowering plants. In addition to organic top dressing, mineral fertilizers are also added to the ground.
The last time fertilizers are added to the site during the period of fruit formation. The site is treated with drugs such as Bud and Agricol.

3. Bad seeds

A common reason why zucchini does not bear fruit well is poor-quality seed. If the seeds for planting are of poor quality or defective, then you will not be able to get a good harvest. Therefore, before planting, you will have to learn how to select crop seeds to plant them.

When choosing seeds, pay attention to their packaging.

Quality seeds are sold in tight packages made of durable paper. It should not have damage or low-quality images. Also, good-quality packages contain information about the seed producer and leave contact details, with the help of which any gardener can contact the manufacturer personally and ask why their zucchini does not grow. If there is nothing of this on the package, it is better to refrain from buying such seeds.

4. Acidic soil

Increased acidity is another reason why zucchini grows slowly. Therefore, before planting this vegetable, the level of soil acidity in the area is determined. To do this, use the usual litmus paper, which is sold in special stores. For the sample, soil is taken from different places on the site in order to accurately determine the acidity of the soil. Then the soil is infused in water for about two hours, after which a litmus test is placed in it. If it changes color, then the soil is not suitable for zucchini.

There are several effective methods for reducing soil acidity. To stabilize the acidity, slaked lime, flour, ground chalk, wood or peat ash are added to the ground. Only in this case, planted zucchini will grow normally.

5. Wrong place

Often, due to an incorrectly chosen place for planting zucchini, it is not possible to get a quality crop. The yield of a vegetable deteriorates if it has been grown for several years in the same place or cucumbers, pumpkins, and tomatoes grew on the plot before it.

What to do if the productivity of zucchini disappears and they bear little fruit? So that the yield of the vegetable does not decrease, you need to choose the right place for growing. It is recommended to choose sites where crops suitable for zucchini have previously been grown. These include carrots, beets, garlic, beans and eggplant. If you do not observe crop rotation, the development of squash bushes will slow down significantly. This happens due to the fact that the seeds grow in an area with depleted soil, in which there are not enough nutrients for normal plant growth.

6. Lowland high water table

Elevated water tables are often the reason why zucchini do not grow during cultivation. Due to the high level of groundwater, the fruiting of vegetables decreases several times. Therefore, it is safe to say that a lot of water for zucchini is also very bad.

In order to somehow deal with high humidity, they make high beds. When creating high ridges from wooden bars, a box is made into which soil is poured for planting. Then organic fertilizers are added to the soil so that the squash bushes grow better. With a large amount of groundwater in the area, high beds are required, because otherwise the bushes will not grow.

7. Lack of heat and light

Sometimes zucchini do not grow, and only small ovaries form on the bushes. This happens if the plants do not have enough sunlight. The lack of lighting appears when vegetables are planted under trees that shade the seedlings. Zucchini are considered light-loving plants and therefore they do not grow well in shaded areas.

8. Bad neighbors

A common reason why zucchini fruits do not grow is unsuitable neighbors. Zucchini is planted near any plants and at the same time they will grow. However, their yield varies depending on where they are planted. For example, when planting zucchini near a pumpkin, the amount of the crop will decrease significantly. Therefore, before growing, you should familiarize yourself with compatible neighbors. Squash bushes grow well near tomatoes, beets, corn and onions.

Correct landing. In order for vegetables to have a high yield, they should be properly planted in the ground. In open soils, zucchini are planted spaciously at a distance of at least 90 cm from each other.
Watering. To increase yields, experienced gardeners recommend regularly watering the bushes. At the same time, at least thirty liters of water is consumed per square meter of a plot with zucchini.
Top dressing. Regular fertilization accelerates the formation of fruits and increases yields. When feeding the bushes, organic fertilizers and nitroammophos are added to the soil to increase the number of fruits.

Conclusion

All gardeners who are fond of growing vegetables in the garden face the problems of growing zucchini. It is recommended that you familiarize yourself with the causes of poor growth of squash seedlings in order to avoid this problem.

Zucchini are unpretentious in cultivation, but if they are not properly cared for, they can give a much more modest harvest, thereby deceiving your expectations. Sometimes it turns out that the culture, if it bears fruit, is far from being as abundant as it should be. Why? And what to do if you tortured an empty flower near zucchini? We will tell in our article.

What is an empty flower?

An empty flower is a flower of a zucchini (cucumber, tomato, pepper) that does not give an ovary. More precisely, he is not able to form a fetus in the future. But do not rush to cut off empty flowers. And consider them harmful or useless. They are male flowers that produce pollen and are therefore designed to pollinate female plants.

Some gardeners believe that barren flowers take away strength from zucchini, so they need to be disposed of. This is a wrong opinion. Zucchini flowers themselves fade rather quickly and fall off shortly after pollination and the appearance of the ovary. If you cut off empty flowers ahead of time, the fertilization process may be disrupted, and you will get a poor harvest.

Even if the ovaries have already formed, and there are much more empty flowers than necessary, picking off the flowers will not affect the crop in any way, because even before flowering, your zucchini had an invisible problem. .

Reasons for the growth of barren flowers on plants

The formation of empty flowers on zucchini is a completely normal phenomenon: they are necessary for pollination. It’s just that sometimes it turns out that much more male flowers that do not give an ovary are formed than female ones. In order to somehow correct the situation, it is important to determine the causes of this phenomenon. Their list might look like this:

Excessive acidity of the soil.
Plants planted too close to each other.
Plants planted in a very dark place.
Lack of insects for crop pollination.
Sowing very fresh seeds that give a lot of empty flowers.
Watering the zucchini with cold water.
Too wet soil.

The cause of the empty flower is plant diseases

Some of the reasons for the abundant appearance of barren flowers are worth talking about in more detail. Zucchini, like other vegetables, often affects the mosaic virus, thereby delaying the growth and development of plants. They cease to bear fruit at all or give out only barren flowers. The mosaic first affects the leaves, and then the whole bushes, and in order to stop the spread of the disease, they must be removed.

In addition to the mosaic virus, zucchini can be affected by powdery mildew, a fungal disease that deforms leaves and cuttings. It also inhibits the growth of plants, since all their forces begin to go to fight the fungus, after which there is no longer any strength left to form ovaries.

Zucchini can also be affected by white rot, when the fruits are covered with a white coating, which soon turns black and causes them to rot. When zucchini is affected by powdery mildew, leaves and stems are treated with colloidal sulfur in the form of a liquid, paste or granules. Disubstituted sodium phosphate or isophene is also used.

White rot is fought with careful crop care. In particular, it is necessary to remove weeds in a timely manner and harvest, properly feed it, including sulfuric zinc, copper sulfate and urea, so that vegetables remain fresh. You can successfully overcome the mosaic virus.

Disease must be fought

Barely noticing yellow and brown spots on the leaves, it is necessary to remove the affected parts, and cauterize the sections with colloidal sulfur. If not individual foci of plants are affected, but all plants as a whole, they must be completely removed.

Other causes of barren flower formation

Weather. In particularly cool and rainy summers, the problem may be the lack of insects to help with pollination. They just don't show up. In addition to this, pollen quickly becomes damp. In this case, the flowers are pollinated by hand - pollen is transferred to the stigmas of female flowers. In this case, the pollen should not be matted, stuck together.
old seeds. Usually, seeds that do not retain their ability to germinate for a very long time and are stored for more than a year, or in unsuitable conditions - for example, at low temperatures - produce mostly male flowers. Women are also formed, but in much smaller numbers. This results in a miserable harvest.
Wrong landing site. Zucchini are unpretentious, but on some soils they are uncomfortable. Planted in heavy shade, they are more likely to be attacked by powdery mildew. In addition, insects that usually pollinate the crop will practically not appear at this place. The result is an abundance of empty flowers and a poor harvest.
Inappropriate plant care. Zucchini is very moisture-loving. However, overdoing it with watering is very dangerous. With strong moisture in the beds, pollen can stick together or completely wash off from male flowers, and then pollination will not occur. It is also necessary to take into account the characteristics of the soil. Too abundant watering, which leads to waterlogging of the soil, and lack of ventilation on dense clay soils is fraught with rotting of the ovaries and their defeat by various diseases. Zucchini love nitrogen fertilizers, but their excess also leads to a poor harvest. At the same time, they grow very rapidly, but do not form ovaries. In such cases, experts recommend giving them a little "shake" - for example, "pin" the growth point, because of which they will actively grow and form fruits.
The role of insect pests. They damage the leaves, stems, flowers of zucchini. As a result, they spend their resources mainly on maintaining their integrity, and not on successfully bearing fruit. The most common pests of zucchini are the sprout fly, aphids, and spider mites. They infect squash at different stages of development.

If you know the reasons for the formation of numerous empty flowers on zucchini, you can figure out how to avoid this later. Basically, your actions should be aimed at selecting high-quality seeds, proper watering and feeding of zucchini, as well as preventing pests and diseases from attacking them.

Often gardeners and gardeners complain that due to empty flowers, the yield level drops significantly.

How to grow zucchini without empty flowers

To plant zucchini, you need to choose a place where there is a neutral or moderate pH level (6-6.8). In order for the zucchini to grow normally, the place for it must be spacious with fertile or fertilized soil. Based on this, seedlings should be planted no thicker than 1x70 centimeters, and the soil should be fertilized with manure or compost in the proportion of 12-15 kg / 1 sq. m, as well as nitrophoska in the ratio of 50 g / sq. m.

If in the soil where the zucchini grows, there is an excess of moisture or it was watered too abundantly, it is necessary to stop watering and dry the soil, because male flowers form at the very beginning of flowering. In order for female-type flowers to appear, the soil is generally dehydrated for a short time. .

If all these rules are followed, but there are no results, then you have oversaturated the soil with fertilizers. To correct the situation, a solution should be prepared from the ashes of non-resinous tree species. For example, from willow ash, rich in potassium and phosphorus.

Tip #1 Add a liter jar of ash to a bucket of water, mix and infuse for 30 minutes. Shake the solution immediately before feeding and mix again.

You can also apply phosphorus-potassium fertilizers (1 tablespoon per bucket of water). The plant is watered with a solution under the root (about 1 liter per 1 plant). The soil during this watering should be moist.

The essence of this event is as follows: the soil contains a lot of nitrogen, so the plant grows involuntarily, without concern that the genus needs to be continued. If you arrange "extreme conditions" for it, reducing the amount of moisture to a minimum and adding potassium and phosphorus, a mechanism is activated that encourages the plant to develop and bear fruit.

Irrigation with cold water also has a bad effect on zucchini: single female flowers appear, and many male ones form. If for various reasons there are no bees for pollination, the plants can be sprayed with the Ovary (Pollen) preparation, and the zucchini will begin to bear fruit.

Flowering and ovary stimulator

For sowing, you need to use two- or three-year-old seeds - then the zucchini will have fewer empty flowers during the growing season. If you have only fresh seeds, then before sowing they need to be steamed: pour water with a temperature of +60 ° C into a thermos and place the seeds there. After heating, transfer them to a damp cloth and cover with plastic wrap.

Tip #2 When sprouts appear, the seeds can be planted in the ground. Such seeds are distinguished by good germination, they give few barren flowers and many ovaries.

In addition, in order to grow a rich crop of zucchini, you must follow a few simple rules:

Do not overexpose plants in a greenhouse or under a film. They need to breathe and pollinate. Under the film, in a closed space with stale air, insects will not make their way and will not be able to transfer pollen. And as a result, you will get empty flowers and - no ovaries.
It should be remembered that it is necessary to properly store the seeds: do not overexpose and do not keep them in rooms with a low temperature. Zucchini seeds, like all other pumpkin seeds, are thermophilic.
Zucchini love shade, but in moderation. Just like excessive watering and abundant fertilizer, too much shading will not do them any good. If the humidity is too high, the fruits begin to rot, when iterating with fertilizers, all the forces of the plant go into the green, and they no longer have enough strength on the ovary.

This is how zucchini flowers look close up

How to deal with barren flowers of other plants

Diseases, pests, and barren flowers are the biggest enemies of the crop. Most often, empty flowers, which means pollination problems, are encountered on cucumbers, zucchini, tomatoes and peppers.

Cucumbers. Cucumbers are the most troublesome. They are the first to form male flowers in order to throw all their strength into building up leaf mass. Therefore, they are subjected to pinching, forcing them to give side shoots with female flowers. New varieties of the gherkin type - such as Janychar, Bettina, German, etc. - have another problem: they begin to lay flowers very early, forming whole bouquets of flowers, of which 2-3 or more will grow into cucumbers. At this time, plants cannot feed such an amount, because they have only 5-8 leaves. Therefore, the first flowers have to be cut off. And only when the shoots grow up to a meter in height, do female flowers leave. If you have a lack of time, or it’s just a pity to pick the flowers, they are left, but the plants are provided with frequent top dressing: every 1.5-2 weeks, the bushes are fed under the root with nitrophos and urea solution per leaf (1 tablespoon per 10 liters of water). At the same time, the preparations "Ovary" and "Buton" cannot be used - from them, lashes grow on cucumbers to the detriment of fruiting.
Tomatoes. Despite the fact that tomatoes are self-pollinating plants, they also have barren flowers. And the drugs "Buton" and "Ovary" here are very helpful in solving the problem. If the plants are sprayed 1-2 times, the yield increases by 15-20%. However, it is not always possible to cope with the empty flower with the help of stimulants. Much more useful is manual pollination when the trellis wire is shaken several times a day. Foliar top dressing with boric acid in the proportion of 10-20 g / 10 l of water is also useful. This solution allows you to increase the number of flowers in the brushes, preventing them from drying out and falling off. From all these activities, the yield increases by 50%.
Pepper. Pepper flowers and ovaries crumble very easily. But this vegetable is very responsive to care. Here you need to use both boric acid and stimulants. And pinch out especially strongly growing shoots so that more flowers are planted during branching. However, for normal pollination, the most important thing is watering. If the soil is dry, all the flowers will be dropped from the pepper. And this can be repeated over and over again. Salvation is in drip irrigation or straw mulch.

6 reasons for the lack of ovary on zucchini

To deal with the problem of barren flowers, it is necessary to find out the reasons for their formation.

Causes	Ways to solve the problem
1. Too fresh seeds were taken for planting. They must lie down for 3 years.	In this situation, the bushes can be forced to give out the ovary by stopping watering for 1-2 weeks. Stress will cause the instinct of self-preservation, and the ovaries on the plants will appear.
2. A lot of leaves on the bushes.	Plants spend a lot of energy on foliage, and not on fruiting. In addition, the leaves create an unnecessary shadow. The foliage must be thinned out, but not in one go, but 3-4 days in a row, 2-3 leaves each.
3. bushes reloaded with ovary.	The female ovary also needs to be regulated: in 1 dose there should be no more than 4 on the bushes. It is necessary: regularly water the bushes; add 40-60 g of nitrophoska per 10 liters of water.
4. Lack of nutrition.	Every 2 weeks, zucchini should be fed: 1 tbsp. l. complex fertilizer per 10 liters of water (nitrophoska, azofoska).
5. Problems with pollination.	Zucchini is not pollinated by bees, but by ants. If they were exterminated in the fight against aphids, then it is necessary to attract bees: spray the bushes with a solution of honey (2-3 tablespoons per 10 liters of water) or manually pollinate.
6. Wrong temperature regime.	In cold summers, zucchini is insulated with lutrasil or film. In hot summers, when pollen becomes sterile, plants should be watered little by little and sprayed with boric acid (10 g per 10 liters of water).

There are many proven methods and fertilizers to get rid of empty flowers.

Rubric for gardeners "Question-Answer"

Question: Why did zucchini grow bitter?

Zucchini is bitter less often than cucumber, but for the same reason: bitterness is given to them by a special substance called curcubitacin, which accumulates in plants. This is due to the influence of various external factors. Most often, this is irregular watering. .

If the summer was rainy, followed by a long period of drought, then zucchini can also grow bitter. It can also happen if zucchini pollinate with other crops (especially decorative pumpkin is dangerous in this regard). Before cooking, it is easy to check the zucchini for bitterness - you need to cut off the stem and lick the vegetable.

Zucchini is a wonderful seasonal vegetable that decorates almost every table in the summer, it is difficult to overestimate them. Growing them in your own garden is not difficult, because this culture is quite unpretentious in its care.

However, sometimes gardeners are faced with the fact that too much is formed. void flowers on squash and, as a result, the harvest is rather meager. To avoid this, you need to know what a barren flower is and how to prevent the appearance of an excessive amount of it.

What is an empty flower

Empty flowers are zucchini flowers that do not form ovaries, that is, fruits do not form in their place. At the same time, they cannot be called completely useless and harmful to plants, so cutting them off is not recommended. Barren flowers are the so-called "male" flowers, they produce pollen that pollinates the "female" flowers.

Some gardeners believe that the empty flower makes the zucchini weaker, as the plant spends energy on the formation and growth of flowers. However, in fact, flowering does not interfere with the development of fruits at all and does not have a negative effect on them. In addition, zucchini flowers themselves fade and fall off very quickly: a few days after pollination, before the appearance of the ovary. It should be remembered that if the empty flowers are cut off too early, this will disrupt the fertilization process of the “female” flowers and then the crop will be very poor.

You can get rid of empty flowers only if the ovaries have already formed, but there are much more empty flowers than necessary. However, even in this case, cutting off the flowers will not give the desired result, because the problem appeared even before the flowering of zucchini.

Reasons for the appearance of an empty flower

The formation of empty flowers on zucchini is a normal phenomenon, since they are needed, as already noted earlier, for pollination. It is read as a problem if there are much more such flowers than necessary for the fertilization of "female" plants. To prevent this phenomenon in the future, it is important to know what provokes the formation of empty flowers and negatively affects the yield of zucchini. A number of reasons for the abundant appearance of "idle" flowers are listed below.

Diseases

Cucurbits are often attacked by mosaic virus, which leads to a slowdown in plant development. It is sick zucchini that give only empty flowers or do not bear fruit at all. Vegetables infected with this virus should be removed and destroyed to prevent spread. In addition, the defeat of zucchini, a fungal disease that leads to the deformation of cuttings and leaves of plants, leads to the abundant formation of barren flowers.

It also slows down the development of vegetables, since their main forces are spent on fighting the disease, and there is no longer any potential for the formation of ovaries. The absence of fruits can also provoke white rot, which causes rotting of plants.

Adverse weather conditions

Zucchini may not produce ovaries even if the weather is very rainy or cool for a long time. During such a period, there may be no insects that are necessary for pollination of flowers, which leads to the absence of fruits. Also, in a too humid environment, pollen can become damp and fall off, which prevents insects (if any) from transferring it from flower to flower. In this case, you need to pollinate zucchini artificially.

bad seeds

The reason for the appearance of an excessively large number of barren flowers on zucchini may be old seeds. The seed material of pumpkin seeds does not retain its germination for a very long time, so if it is stored for more than a year or has been in unsuitable conditions for a long time, then as a result, the plants produce many "male" flowers. At the same time, "female" flowers are also formed, but there are too few of them and the harvest is poor.

Unsuitable place to land

In general, zucchini is quite unpretentious to the soil, but you should still carefully choose a place for planting them. So, if you grow them in dense shade, then the plants can be affected by powdery mildew. In addition, insects that pollinate flowers do not fly into such beds. As a result - the absence of ovaries and no chance of a rich harvest.

Wrong watering

Zucchini are very fond of moisture, however, gardeners should be careful not to overdo it with watering. If you moisten the beds too much, then the pollen can stick together or even wash off from the flowers and then the zucchini will not be pollinated. Also, waterlogging of the soil leads to rotting of plants and their defeat by various diseases.

Pest attacks

Insect pests can infect squash at different stages of development, damaging their leaves, stems and even flowers. As a result, plants spend their potential on the struggle for survival and the renewal of tissue integrity, and not on the formation of ovaries. Most of all in this regard, zucchini suffer from attacks of spider mites, aphids and sprout flies.

An actual problem in cultivation is the appearance of barren flowers, male-type flowers that do not produce fruits. As a rule, they are cut off, but they are necessary for the pollination of female flowers, respectively, and the cultivation of fruits. You can identify them by a long thin stem and spikes, for women - a short, smooth stem.

empty flowers

There are many reasons that can cause the appearance of a large number of empty flowers: these are weather conditions, and more.

To avoid this, it is necessary to know how to prevent these phenomena and how to deal with them.

Benefit

For healthy and full-fledged fertilization, both female and male flowers are needed, preferably in the same amount. Without the presence of barren flowers, pollination will not occur and there will be no fruit.

Harm

The main reason for the harm of a large number of empty flowers is the lack of fruits.
Also, when a lot of empty flowers form on zucchini, it depletes. However, they can also be a focus of diseases or attract insect pests.

Reasons for the appearance

A barren flower can be caused by one or more factors. It is necessary to find out why the barren flower appears, then the way to eliminate it will be clear.

bad seeds

The main cause of barren flowers on zucchini are bad ones. For planting, you need to take old seeds (2-3 years of storage), young ones give a small offspring. To increase the effectiveness of young seeds, you need to fill them with hot water (more than 50 ° C) for 5-6 hours, then wrap them with a damp cloth and film. Plant when sprouts appear.
Seeds that have been stored at high humidity or low temperatures also produce a small yield. Therefore, before planting, they need to be warmed up.

If the seeds are purchased, you need to pay attention to the packaging. The F1 mark indicates that these are hybrid seeds and have all the properties described on the package. But in F2, the second generation, the properties may be lost, for example, the yield will decrease.

Did you know? Zucchini is a fruit because it is a flowering plant that reproduces with seeds!

Purchased seeds may be of poor quality (damaged, improperly stored, etc.).

care mistakes

Zucchini are moisture-loving, but abundant can cause pollen to stick together, wash it off from male flowers, and waterlog the soil. This leads to rotting of the fetus and plant, the appearance of diseases.
The formation of flowers occurs in turn: first male, then female, each period needs its own. Namely, for women it is necessary to dry the earth a little. You should not water the zucchini again, if the leaves have wilted a little in the sun, by the evening they will become fresh again.

The use of cold water for water results in a few female flowers and many barren flowers. The water should be warm (from 16 ° C), watering only under the root, and 5-7 days before harvesting the fruits, watering should be stopped.

Excess fertilizers, especially nitrogen fertilizers, can cause the plant to develop actively, but the ovaries will not appear.
It is necessary to "pin" the beginning of growth or create new conditions for it to form fruits. For example, use phosphorus for (1 tablespoon per 15 liters of water), reduce. This will stimulate the plant to develop.

Did you know? In England, an annual festival of paintings made from zucchini and pumpkins is held.

Growing in the shade will not bring many fruits, they need to be planted at a certain distance from each other so that they do not shade each other.

Diseases

There are several types of diseases, each of them can cause barren flowers on zucchini:

To prevent diseases, you need to carefully handle the tools and monitor the condition of the zucchini.

Important! All of these diseases can survive the winter in the seeds or leftovers of infected squash, so they must be destroyed.

Seeds can be disinfected- place in water at a temperature of 50-70 ° C for 15-20 minutes, then for 3-4 minutes in cold water, then dry.

Pests

To know how to deal with barren flowers on zucchini, it must be borne in mind that pests can also cause this phenomenon:

Important! It is necessary to remove the remains of diseased zucchini, they can become a breeding ground for the spread of pests.

Under good weather conditions and proper care, insects attack extremely rarely. A good environment for their appearance is a humid, closed space.

Unsuitable soil

Unsuitable - depleted, not fertilized, too wet or dry land. On very wet, swampy ground, female flowers appear extremely rarely.
What to do if a barren flower appeared on zucchini with proper watering? The reason may be the land oversaturated with fertilizers. It is necessary to spray it with a solution (500 g of ash per bucket of water) or use a tincture of potassium and phosphorus.

Another reason is the depleted land on which the same crop has been grown for many years. In this case, it is necessary to change the landing site, and plant something else on the old land.

The reason for the appearance of barren flowers may be elevated earth. To reduce acidity, you can use lime (60 kg of lime per 1 weave), evenly distribute before digging, preferably in the fall, repeating the procedure once every 8-9 years. Or use fertilizers on lime: tufa, and limestone flour.

Weather

Rainy weather can reduce the yield. In order for the fruits to appear, they are necessary, but in the rainy seasons they simply do not arrive.
To lure the bees, you need to gently push the flower petals apart and spray the plants with a solution of honey or sugar (3 tablespoons per 1 glass of water).

In the complete absence of pollinators, artificial insemination should be used. It is necessary to carry out the procedure from 8 to 12 hours, for this, take yellow pollen from the barren flower and place it on the stigma of the female flower.
It is also impossible to allow high humidity during the rains, especially if the zucchini is planted in the shade. On sunny hot days, you should not water them too abundantly, even if the leaves have fallen.

Every summer resident should know why an empty flower turns out on zucchini, what to do if such a problem arises, how to avoid the phenomenon when the plant does not bear fruit. This culture is unpretentious, but with improper care it can give a very modest harvest, the ovary is not formed as abundantly as it should.

Zucchini bloom with barren flowers - what to do?

Such a phenomenon as a barren flower is the absence of an ovary on the flowers of a plant. Zucchini buds are designed to form a fruit. This does not mean that barren flowers are not needed at all - these are male corollas that form pollen, and they are required for pollination of female plants. The color of zucchini fades on its own after some time, when the ovary appears. If they are cut off ahead of time, then the pollination process may be disrupted. If many zucchini went into a barren flower and there is too much of it, this is already an abnormal situation.

How to determine the empty flower on zucchini?

Every gardener should know how to distinguish an empty flower from zucchini. It is easy to identify male flowers - they have a long thin stem with thorns. While in women it is short and smooth. In addition, the barren flower does not have a pistil and therefore is not able to form a fruit. For successful and complete pollination and the formation of ovaries, both those and other flowers are needed, preferably in equal numbers. Without the presence of barren flowers, pollination will not occur and there will be no harvest.

Why do zucchini bloom with barren flowers?

The formation of male flowers is normal. But when their number exceeds the number of females by several times, they deplete the plant and become a focus of diseases. An empty flower on zucchini appears for several reasons:

old seeds. Seeds stored for more than 3 years or at low temperatures produce more male flowers.
Wrong landing site. Planted in dense shade, zucchini is affected by powdery mildew. Insects do not appear in such a place, the result is an abundance of barren flowers.
Weather. Rainy weather can be the reason for a poor harvest.
Wrong care. Abundant watering leads to waterlogging of the soil, fraught with decay of the ovaries. An excess of nitrogen fertilizers is harmful - plants grow rapidly, but do not form ovaries.
Diseases. Several types of diseases and pests can lead to the formation of barren flowers: mosaic virus, powdery mildew, white rot, sprout fly, aphid, spider mite.

Zucchini do not tie, one barren flower - what to do?

When growing zucchini, the fight against barren flowers comes down to observing the correct agricultural practices. By remembering a few rules, you can get a rich harvest. Empty flower on zucchini - what to do:

Do not overexpose the seeds for more than 3 years and store at low temperatures. It is advisable to warm pumpkin seeds before planting. To increase the efficiency of young seeds, before planting, it is better to fill them with heated water, wrap them with a damp cloth, and plant them when sprouts appear.
Planting requires moderately moist soil with low acidity. The site should be lit or slightly shaded.
