Quite a common problem - the lack of ovaries in safely flowering cucumbers. This is frustrating, because all the work on growing seedlings, planting it in a permanent place of growth, watering, loosening, removing weeds, fighting pests and diseases have been invested in order to ultimately obtain a crop. What can I do if the cucumber is empty? What was done wrong?
Why does the cucumber blossom, but does not form ovaries?
The reasons can be several:
- There is no pollination. Bee-polluted varieties of crops require access to pollinators. And if the bees can not get into the greenhouse or on the windowsill, then you can not wait for the ovaries.
- Too hot. High air temperature (above + 35 ° C), for hybrids and bee-dusted varieties, causes pollen sterilization. As a result, plants bloom, but can not pollen and ovaries, respectively, no.
- Weak seedlings and inappropriate conditions. If conditions do not suit cucumbers, they will bloom with male flowers without fruit.
- It was not time. At the very beginning of flowering, cucumbers first release a few blossoms, which is quite normal.
Cucumbers bloom without ovary
Consider a little more detail, why cucumbers bloom abundantly, and the ovary does not.
The delay in female flowers and late ovaries is primarily due to the poor quality of the seeds. If you plant fresh seeds, the plants that grow from them will actively produce male flowers and only later will women's ovaries begin to appear. To avoid this, it is better to take seeds 2-3 years ago. Then the female flowers will appear before the male or simultaneously with them and with pollination everything will be in order.
If you do not know the prescription of seeds, you can warm them before planting or, conversely, harden frost. Then women's flowers from plants that have grown from them will appear on time.
The reason that cucumber blossoms and ovaries dry out may be a violation of growing conditions. Reconsider the mode of lighting, watering, air and ground temperature. The roots of cucumbers do not like the cold, they grow poorly, do not absorb nutrients, and because of excess watering rot. The lack of the same illumination and high air temperature leads to the fact that cucumbers are stretched and have thin and frail stems. Such an unhealthy atmosphere does not promote good fruit bearing.
Too moist soil adversely affects the fructification of cucumbers. What to do if the cucumber flowers, but not the ovary? Try to dry the soil, that is, do not water the bed for several days. Once the leaves on the plants are slightly wilted, a large number of female flowers will immediately appear. Do not overdo it and do not overdry the land.
Another reason why cucumbers are blooming, and no ovaries can be a violation of the balance of nutrients. If there is too much nitrogen in the soil, it causes rapid growth and build-up of green mass, as well as an abundance of gems. To correct the situation, you can feed the cucumber extract of superphosphate (dilute 2 tablespoons in 10 liters of water). Still it is possible to try to water plants an infusion
An additional incentive to produce female flowers from cucumbers can be pinching the tops of the stem. This will stop the growth in length and cause the appearance of lateral processes with female flowers on them.
What to do with the vapors?
When we have achieved the appearance of a sufficient number of female flowers with ovaries, the following question arises: do we need hollows, what should we do with them? Someone removes them, believing that this will lead to the growth of female flowers. However, this does not help, and can only worsen the conditions of pollination. Blossoms, as a rule, dry up and disappear themselves.
