Pustaceae occur in many cultures, including cucumbers, tomatoes, and zucchini. If we consider male flowers in dioecious representatives of the flora, the situation looks quite natural.
However, if female inflorescences do not form a fetus, it looks suspicious. In any case, it is necessary to look for the cause of the problem, eliminate it. There are many reasons why flowers do not form an ovary; it is necessary to consider the main causes of such manifestations.
Common Causes of Empty Flowers
If the plant blooms and does not bear fruit, it can be talk about poor care and lack of pollinators. The latter is especially true for greenhouse crops: a person grows cucumbers and tomatoes without access to pollinating insects, and then he is surprised at the absence of ovaries. To solve the problem, it is necessary either to provide access to natural pollinators, or to acquire a soft brush and pollinate inflorescences on their own, transferring pollen from one plant to another.
Inadequate care also causes an abundant appearance of empty flowers. Plants of any kind will cease to bear fruit in case of excessive dryness or cold, with a deficit of sunlight - if we are not talking about shady species. When watering with cold water or non-compliance with its regime, when watering in the midst of a sunny day, for example, empty flowers also appear.
Why do empty flowers form in cucumbers?
Cucumbers are predominantly a greenhouse plant, although many gardeners practice their cultivation in open ground. In addition to common problems with pollinators in a greenhouse, cucumbers tend to produce empty flowers when the gardener not harvesting on time. If overgrown cucumbers are present on the stem, or there is a large volume of fruits ready for removal, the new flowers will turn out to be empty.
Overheating in greenhouses - also a characteristic phenomenon. If the temperatures are excessively high, cucumbers quickly lose moisture, the leaves turn yellow, and new flowers do not bring a crop. If the heat is too strong, cucumbers planted on the street may suffer. Also, any shock effects - extreme temperature changes, watering with cold water, lead to a decrease in fruiting due to empty flowers.
Interesting fact: entering the period of fruiting, the cucumber first gives the male flowers, which fall by themselves, and only then come the female. Do not be surprised if the first flowers on the plant turn out to be empty flowers. And also it is worth sowing seeds that have been stored for 2-3 years. With a longer or shorter shelf life, there are more empty flowers.
Why is there a lot of empty flowers on tomatoes?
Tomatoes are also often grown in greenhouses, where they can remain without pollinators or suffer from high temperatures. But in addition, the yield of these plants is closely related to the amount of nutrients in the soil, and if there are not enough, there will be many empty flowers. Also Do not plant tomatoes close to each other, they will compete for nutrients, which will also lead to numerous barren flowers even with the proper application of fertilizers.
Why are there so many empty flowers on the marrows?
Zucchini, pumpkins, as well as melons and watermelons sometimes also show a tendency to empty flowers, which happens usually due to cold weather or strong daily temperature changesor with insufficient watering. Plants of the above crops can also not be planted too close to each other, they also have a fairly high need for nutrients.
Interesting fact: Pumpkins and zucchini can be planted even near the dunghill or in the place where it was recently. The plant will not only not “burn out”, but will also produce a wonderful crop.
How to get rid of empty flowers?
In a certain amount, empty flowers are still needed, they give a lot of pollen, provide pollination of other flowers, the formation of a good ovary on them. It is not worth breaking off the empty flowers, they can go through their natural life cycle without taking a lot of energy from the plant. But if there are too many of them, it is worth taking certain measures to minimize the number of sterile flowers.
It is necessary to reconsider the conditions for growing the culture, if there is an assumption that the empty flowers appear for agrotechnical reasons. In the cold, you can cover the plants with a film, in the heat - ventilate the greenhouse. It is necessary to solve the issue with fertilizers, to make sure that they are applied in the required amount and in a timely manner. You can also use special tools that increase the chance of getting an ovary - they are sold in stores.
Thus, barren flowers occur under inappropriate growing conditions or in the absence of pollination.Gardeners and gardeners have the ability to eliminate this undesirable phenomenon.
