Tomatoes are not set in the greenhouse, what should I do?
Content:
This should be very offensive and incomprehensible. You have grown excellent, sturdy seedlings. They transplanted her to the greenhouse in a timely manner. We did everything to make it take root quickly. And also adapted to a new place. And here comes the long-awaited flowering. And tomatoes are not tied in the greenhouse. What to do?. Solid barren flowers and not a single tomato.
First of all, you need to determine the reason why tomatoes are not tied in the greenhouse. And then make every effort to eliminate it. Once the plants are blooming, then they have enough moisture and nutrition. Therefore, the problem is not with the composition of the soil. And also not in watering mode. There are not many options left. And we will consider all of them later in this article.
Tomatoes are not set in the greenhouse due to air temperature

Tomatoes love warmth. That is why they are more often planted in a greenhouse than in open ground. Because it is easier to control the environmental conditions there. But in summer, in especially hot weather, the air temperature in a closed greenhouse rises. So much so that plant pollen is sterilized. And even all the bees in the world will not help your tomatoes in pollination.
Because at temperatures above +32 degrees, this is no longer possible. Therefore, experienced gardeners recommend making sure that the temperature does not rise above + 28 ... + 29 degrees. Ideally, it remained at +25 degrees. This is how the plants will feel most comfortable. Be sure to ventilate the greenhouse. If necessary, pull on the geotag to shade the tomatoes a little. Also, install several weber or water barrels that will absorb some of the heat.
Air humidity
But keep in mind that the installation of additional water tanks can affect the humidity, which should not rise above 70 percent. If the humidity is too high, the pollen gets wet and rolls down, then crumbles and, again, pollination does not occur. It is necessary to water the tomatoes rarely and carefully (a lot, at the root, without splashing water), then be sure to mulch the ground to prevent moisture evaporation. This will also help to avoid the formation of condensation, which favors the multiplication of pathogenic microorganisms and bacteria.
Pollination process
Obviously, if pollination does not occur, then there will be no ovaries. And how can pollination occur if the greenhouse doors are closed and there is no air movement inside, and bees and bumblebees cannot get there? So you need to either regularly ventilate (and we have already found this out in the paragraph about the air temperature) or assign this role to yourself and come to the greenhouse every morning and evening and shake the tomato bushes a little so that the pollen starts moving.
Tomatoes are not tied. Stepchildren
The tomato is growing and is not aware of your plans to harvest in the next couple of months. It was conceived by nature as a solid perennial bush, therefore, first of all, it will try to grow foliage as actively as possible, flowering and fruiting is of little interest to it. And if you still from the heart fertilized the earth with organic fertilizers and nitrogen, then there will be no limit to the growth of tomato bushes, it is in this case that stepsons begin to grow abundantly - additional branches from the axils of the main leaf. Here it is already necessary to urgently form a bush, removing all stepchildren and leaving only those branches on which the formation of fruits is expected.If this is not done in a timely manner, then instead of harvesting tomatoes, you will have beautiful green bushes.
Insufficient boron content
For full growth, tomatoes need a lot of nutrients, and a lack of any of them can cause abnormalities in the development of the plant or a deterioration in its condition. So, the level of boron affects flowering and the formation of ovaries, its shortage noticeably affects the productivity of tomatoes. Since it is extremely difficult to obtain boron from the soil, it is added additionally using foliar fertilization, that is, by spraying the plants. To stimulate tomatoes, it is necessary to spray the plants from a spray bottle every two weeks with a freshly prepared solution of 5 grams of boric acid in a ten-liter bucket of water.
Tomatoes are not tied in the greenhouse: conclusions
As you can see, it will not be difficult to find the reason for the absence of ovaries, it is necessary to work out five main points and eliminate possible errors: adjust the temperature and humidity of the air, establish the pollination process, deal with the stepsons and restore the boron content to the required level. All this will definitely benefit your tomatoes, and soon you will see that more and more ovaries appear every day.
