Cucumbers bloom, but there is no ovary: what to do, how to spray and process

One of the favorite vegetables of summer residents is cucumber, which begins to bear fruit early in greenhouses. But it happens that all the conditions are created, but it is not clear why cucumbers are not tied in the greenhouse. You can fix the problem if you know the reason for the lack of ovaries and fruits.

Why don't cucumbers bloom

The fruiting depends on the appearance of flowers on the vegetable bushes. Both the appearance of fruits and the yield of vegetables depend on the number of female inflorescences. But sometimes, such a situation arises that cucumbers do not bloom, and this happens for various reasons:

The lack of flowering is related to the quality of the seeds. If the seeds are stored for more than two or three years, then they rarely give viable seedlings. But seeds just harvested from fruits are not always good material for the growth and flowering of cucumbers.
Vegetables are fruitless, in which the nutritional balance is disturbed during the growing season. Overdoing it with nitrogenous fertilizers, they get long lashes and a lot of lush greenery. But the plant is not going to bloom.
Watering with cold water leads to the fact that the flowers in the axils of the leaves do not appear for a long time. It is clear why there is no cucumber crop either.
Excess moisture in the soil negatively affects the plant, when the stems begin to rot, and the flowers that appear dry out.
If during flowering the air temperature in the greenhouse rises, reaching a mark of 30 degrees, then the beginnings of flowers crumble.
Stuffiness, lack of air, tightness in the greenhouse will not allow plants to develop properly, then there is no ovary on cucumbers. Suspension of the growth of lateral shoots, on which fruits develop from female flowers, will lead to crop loss.

Proper preparation for planting a vegetable, organizing care for it in a greenhouse, will help cucumbers to be with flowers.

Why do cucumber ovaries not grow in the greenhouse

In hot weather, the ovaries on cucumbers appear on time, but grow poorly, dry up.

The ovaries do not develop because:

the greenhouse is not ventilated;
greenhouse vegetables are at an air temperature of over 32 degrees and a humidity of 90 percent;
plants are not pollinated due to the lack of male flowers on the plant and insects in the greenhouse;
not enough nutrition in the soil.

Diseased plants also will not give full-fledged ovaries:

The appearance of rot is associated with the defeat of pathogenic fungi. With the development of infection, all parts of the plant are covered with white mycelium. The plant stops growing.To save cucumbers, affected leaves, stems, ovaries are cut off, sprinkled with lime or crushed coal on top. Thickened plantings are thinned out, removing diseased bushes. Then the ovaries will begin to develop more actively, having received enough air.
Powdery mildew inhibits the growth of cucumbers, their ovaries. As soon as a white coating appears on the leaves, it is necessary to pollinate the cucumbers with sulfuric powder.
Brown spot occurs when the greenhouse is cool and humid. Treatment with Bordeaux liquid will stop the development of the disease.

Having established the reason that the cucumbers are not tied, competent agrotechnical procedures are carried out.

Why cucumbers bloom but no fruits: competent planting organization

If cucumbers are not tied in the greenhouse, then the reason lies in the planting and preparation for it.

The composition of the soil for cucumbers should be nutritious. To set fruits, prepare a mixture of equal parts of turf, peat, sand and vermiculite. Instead of vermiculite, they take sawdust and some coconut fiber.

He althy seedlings appear faster and cucumbers will develop better if rotted manure is put in the basis of the soil substrate, adding half as much sod land and a little sand to it. Seedlings do not like acidic soils, so it is better to neutralize the pH level.

In the garden in the greenhouse during the flowering of the plant, there should be enough potassium, phosphorus, magnesium. Elements are applied in the form of fertilizers to the soil in advance. Treat the soil from pathogenic fungi by pouring boiling water or a weak solution of potassium permanganate.

Cucumber seeds undergo pre-sowing treatment. Them:

sorted by dipping in saline;
disinfected in 1% sodium permanganate solution;
sprout in wet layers of gauze or toilet paper.

It is better to sow cucumbers immediately in the greenhouse, as seedlings do not tolerate picking. To do this, compost beds are prepared indoors, a nutrient soil mixture is placed on top of them, the layer of which is twenty-five centimeters. After abundant watering, two seeds are placed in the wells. Cucumbers will be better tied if there are no more than four plants per square meter.

The sown bed is covered with polyethylene film from above. When shoots appear, the shelter is removed.

Why ovaries do not develop: what to do

If there are few female flowers, then the fruits should not be expected in large quantities. And from the fallen ovaries, all the more they can not wait. Flowers can dry out due to temperature changes. You can save planting vegetables by mulching. They cover the soil around the bushes with a layer of sawdust, straw, hay, fallen leaves.Mulch will help retain moisture in the ground and prevent the growth of weeds.

Hypercooling is not allowed, otherwise there will be no ovaries on cucumbers in the greenhouse. Therefore, during flowering, set the temperature control of the air in the greenhouse.

Cucumbers don't set when they lack potassium, magnesium and phosphorus. If soils in greenhouses are poor, cucumbers are fertilized every week. In order for vegetables to grow, they alternate fertilizing with organic matter and minerals. You can sprinkle the leaves of the plant on top with nutrient solutions. This will allow you not to run into a problem when cucumbers bloom, but there are no ovaries. And they will not turn yellow.

You can increase the growth and number of ovaries by regular harvesting. Cucumbers are harvested every morning, then the duration of fruiting increases until late autumn. In a fruiting cucumber, ovaries are constantly formed.

Cucumber varieties are either self-pollinated or not. A self-pollinating vegetable grows better in greenhouses. It is chosen because it is not necessary to bother with pollination in order to grow fruits. Shoots are quickly obtained from seeds, and there are much more fruits on such plants. Self-pollinated cucumbers will not turn yellow. 96 percent of the ovaries turn into greens with tender flesh and crispy taste.

When a situation arises that cucumbers bloom, but do not bear fruit, the reason lies in the lack of phosphorus in the soil. You can take a battery from wood ash, it is better absorbed from it by the roots of the plant. To prepare a nutrient solution, two tablespoons of ash are diluted in ten liters of water. Cucumber beds are processed in cloudy weather after loosening the soil. After feeding, the fruits do not dry out and pour faster.

You can improve fruiting by pinching the central stem and side shoots of the first and second levels. The procedure will lead to the fact that the number of female flowers will increase, and, therefore, there will be a lot of cucumbers.

Why flowers fall but no cucumbers

If you don’t know what to do when cucumbers bloom and there is no ovary, then you need to reconsider the conditions for growing the plant, the rules for caring for it.

The vegetable starts dropping flowers when:

irrigation regime violated - the soil is either dry or waterlogged;
close to groundwater;
not enough phosphorus, potassium in the beds;
lack of light and air in the greenhouse.

The formation of a bush in one or two stems must be carried out. If the central shoot has grown, and the side stems do not lengthen, then the yield will be small. After all, the main fruits are tied on lashes of the second and third order.

But cutting off male flowers, or barren flowers, is completely unacceptable. They are needed for pollination. If there are too many, then it is necessary to reduce the frequency of watering, and spray the cucumbers from above.

When cucumbers do not bear fruit, it is necessary to water the ridges abundantly and feed them with rotted manure. It is better to treat plants with special fertilizers such as Azofoska, Kemira.

Constantly moist soil in the greenhouse will not allow the fruits to pour. The soil must be dried without watering for three days. Leaves will wilt, and female flowers will please with fruit set.

During periods when cucumbers do not pour, remain small, it is necessary:

attract insects for pollination;
apply foliar top dressing by taking a tablespoon of urea and three baking soda into a bucket of water;
spray bushes with warm water.

Prevent the appearance of fallen flowers by treating cucumbers with a suspension of copper oxychloride at a concentration of 0.4 percent or Bordeaux liquid.
