5 reasons why cucumbers bloom, but there is no ovary

Often summer residents are faced with such a problem as the abundant flowering of cucumbers, but at the same time the lack of a crop. What is the reason for the appearance of empty flowers, and what to do? Why are there many flowers, but no harvest? Why do only barren flowers appear without an ovary? What to do for their appearance? Gardeners have a lot of questions, and we will try to answer them.

So, if there is no ovary for cucumbers, you should check and, if available, eliminate the negative factors that affect this process. And these can be temperatures over thirty-five degrees, relative humidity over ninety percent, lack of pollination, lack of nutrition in the soil.

Many people wonder if empty flowers should be removed. Yes, indeed, by removing them, you can improve pollination. But they themselves quickly turn yellow and fall off, although they grow quite quickly. Therefore, it is up to the gardener to decide whether to do this or not.

Some hybrid varieties, where female flowers predominate, may not be pollinated due to a lack of male ones. To fix this, you need to seed another variety of cucumbers for pollination.

The lack of pollination is also possible due to prolonged cool weather, as a result of which pollinating insects simply do not fly and do not cope with their task. Then the tops grow, but there are no fruits.

But this can be fixed by pollinating the flowers by hand when they bloom. To do this, they take male flowers, tear off the petals from it and carefully put them into the female ones. You can also pollinate the stigma of a female flower with a brush.

thickening

Why is the correct planting of seedlings very important for the appearance of ovaries on cucumbers? Because with a strong thickening, cucumbers will not bear fruit. But this can be fixed by weeding the plant.

It is necessary to monitor the timely harvest. Overripe fruits interfere with the formation of a new ovary. There are some varieties that are recommended to be harvested every other day or even every day, as they grow quite quickly.

Violation of growing conditions

To obtain an ovary and, as a result, a good harvest, there are a number of conditions, observing which you can grow a certain crop.

One of the conditions for the proper cultivation of cucumbers is good watering. Seedlings should not be watered with water colder than twenty-five degrees, but in any case, the water should not be colder than the soil.

But an excess of moisture is just as bad as insufficient soil moisture. The key here is to strike the right balance. If the soil is waterlogged, it must be dried for several days. After drying and a slight wilting of the leaves, many female flowers will appear, which will lead to the appearance of the ovary of cucumbers. But again, do not dry out the ground too much, this can lead to the death of the plant.

The proximity of groundwater can also adversely affect the growth of the plant and its yield. This is due to the fact that cucumbers have a fairly well developed root system, and such conditions can simply ruin it.

The ambient temperature is also a key factor for a good cucumber harvest. High temperatures can lead to the death of the plant, in fact, and frosts also adversely affect the fruiting process.

bad seeds

Often the reason for the appearance of empty flowers and the lack of fruiting lies in the quality of the seeds. If fresh seeds are sown, most likely, only male flowers (barren flowers) grow, if two or three years ago, on the contrary, female flowers will grow first, then only male ones. If the statute of limitations for seeds cannot be determined, but they need to be planted, after warming up the seeds before planting, then female flowers will appear much earlier, along with male barren flowers.

For good seed germination, you need to monitor the level of phosphorus in the ground. Potash fertilizers are also important.

There are varieties of cucumbers where female flowers are formed later. These are late cucumbers. In such conditions, you need to wait a little longer for fruiting than usual.

Favorable conditions will be the hardening of swollen seeds. To do this, the swollen seeds are placed in the refrigerator for several days, then they are dried and sown. Such hardened seeds germinate earlier. They can germinate even at a lower temperature than is usually required.

The optimum temperature for seed germination: twelve to thirteen degrees. Hardened seeds can germinate at ten degrees Celsius.

Nutritional imbalance

Violation of the balance of nutrients is also a significant reason for the lack of ovary on cucumbers, when one microelement predominates in the soil, and the second is not. Violations of this balance can cause an excess of nitrogen fertilizers in the soil. Because of this excess, all the strength of the plant is lost in the exuberant growth of leaves and barren flowers.

For good fruiting of cucumbers, a uniform nutrient content in the soil is required. In order to normalize the soil, fertilizing with phosphate fertilizers or infusion of wood ash is suitable. An extract from superphosphates is also suitable for these purposes. Such an extract is being prepared at the rate of two tablespoons of the mixture per ten liters of hot water.

When nutrients are disturbed in the soil, many ovaries can form, but due to lack of strength, they can fall off. Therefore, if enough flowers have formed on the plant, they need to be fed every seven days with an infusion of mullein and urea. Also, many recipes and tips can be found on the Internet.

To ensure the optimal content of organic matter in the soil, you need to put manure, humus or compost under the plants at the rate of one bucket per square meter of soil.

On sandy soils, cucumbers need magnesium, so Kalimag is good to apply in such soil.

If all the negative factors that prevent the plant from fruiting normally are removed, but nothing helps, the cucumbers bloom, but the ovaries do not grow, as an option, you can pinch the top of the foliage. This will stop the growth of the stem in length, cause the growth of lateral pagons and, as a result, the growth of female flowers.

To increase the resistance of the plant to stressful situations, it is necessary to carry out foliar feeding of cucumbers.
