So you rejoice in the abundant flowering and the first tiny cucumbers. While waiting for the harvest, you make plans. But here's the bad luck: the ovary of cucumbers turns yellow and falls off. What is the reason? Something went wrong? What plants lack to give all their strength to fruiting? Often, gardeners are upset by this problem, and it is not surprising, because cucumbers do not develop at the very beginning. There may be several reasons for this.
The main thing is to find the cause and eliminate it.
Let's consider the most common causes of yellowing and wilting of the ovaries of still unformed cucumbers. It would seem that you are doing everything right. But what can prevent plants from developing well and giving a full harvest.
It was not in vain that it laid so much ovary, because there was a potential provided by nature. For help, we turned to experienced amateur gardeners with experience. And here are the secrets we learned from them.
Stepson must be literate
Some consider the reason for the falling off of the ovary is pinching. Say, this procedure reduces the yield. This opinion is erroneous. Remember, everything that grows from the sinuses of the first 3-5 leaves must be removed. Stepsons who begin to grow taller must be pinched above the 2nd sheet.
The thicker the worse
The plantings should not be thickened. In this case, there is a deficiency of plant nutrients, which cannot provide food for the numerous ovary. It is discarded. Therefore, you need to carefully read the recommendations on the bags with cucumber seeds, which indicate the frequency of planting. Be sure to consider this.
Especially dangerous is thickening in a greenhouse, where ventilation is difficult, humidity rises, and the risk of developing fungal diseases increases.
Top dressing and watering
With the growth of cucumber lashes, both abundant feeding with manure and high-quality watering are needed. Only then will they receive the necessary nutrients and moisture. Cattle slurry is diluted with water in a ratio of 1 to 10 and poured under each plant after watering. In the absence of a mullein, you can simply insist on weeds, the effect will be no worse, and the benefit is great - the plant will gain strength to grow, turn green and get stronger. And all thanks to nitrogen, which is extremely necessary for the plant during the period of intensive growth (before flowering).
During the flowering and fruiting period, requests will change dramatically. The presence of nitrogen and phosphorus will no longer be enough for cucumbers. You will need nutrition from potassium-phosphorus fertilizers. Then you should add ash (1 glass), superphosphate (1 tablespoon per bucket of water) to the mullein or herbal infusions. A good option is drugs purchased from gardening stores. They contain the full composition of mineral fertilizers. And do not forget to read the instructions before use. The most popular among gardeners are as follows:
- "Ovary";
- "Azofoska";
- "Kemira";
- "Solution".
And about watering. Too moist soil or excessively dry soil creates favorable conditions for the death of ovaries. Here you need to find a middle ground. It all depends on how the soil retains moisture. Clay is better, sandy is worse. But overflowing is even worse than underwatering. If the roots rot, the plant is finished!
Pollination and temperature
If only bee-pollinated hybrids are planted in greenhouses, then there is no need to wait for the harvest. These varieties of cucumbers mainly have female flowers, and they will not bear fruit without pollination. Those who know about it plant insects that carry pollen. 
Pollination can be done artificially. Take a male flower from a cucumber lash and touch it to the stigma of the pistil - a female flower. So, pollen is transferred from a male flower to a female one. But it is best not to plant bee-pollinated varieties in a greenhouse, for this there are special ones - self-pollinated, parthenocarpic.
The ovary can dry out because cucumbers are irregularly harvested, they are grown on lashes to huge sizes. Such fruits will not allow future generations to take shape. After all, they take away nutrients.
A little trick: you can put a barrel in which the manure has fermented in the greenhouse, this will increase the number of female flowers.
You also need to strictly monitor the temperature regime. With an excessive increase in temperature during the day, the ovaries can simply boil and crumble. And the contrast between day and night temperatures, between the temperature of the air and the ground, is also not in the hands of the crop. The cucumber at the time of flowering is a delicate and receptive plant. Therefore, it is during this period that it should not experience any stress.
Long noticed
- When planting is done with last year's seeds (fresh) or unheated, the amount of empty ovary increases.
- The older the seeds are, the more female flowers they form. But after 6–8 years, cucumber seeds lose their germination.
- Under unfavorable conditions, the plant makes a supply of flowers just in case. It turns out that more ovaries are formed than it can feed. If all flowers are pollinated, the plant will shed excess ovaries. This is a normal process.
- Never pick barren flowers (male flowers)! Pollination of female flowers will not occur without them. If, nevertheless, you observe a large number of them, do not water, but only moisten the soil. Resume watering when the leaves are slightly wrinkled.
Think about what you did wrong, eliminate the reasons for the non-ripening of the ovaries, and your garden will delight you with an abundance of shiny emerald cucumbers.
