Why tomatoes abort: Plants make flowers, they bloom, but they don’t bear fruit, and tomatoes don’t. Reasons why tomatoes do not bear fruit and flowers appear and dry without bearing fruit.
Tomato plants only have flowers, but they do not bear fruit. There are many reasons why tomatoes do not bear fruit. After all, if the tomato crop does not have enough water or food, then not even the flowers will appear. But if the flowers are plentiful, then this is not the problem.
Fallen flowers – a big problem in tomato culture. What can you do to prevent lost production?
Why do tomatoes abort? Reason: the temperature is too high
Tomatoes abort due to high temperature, especially in the case of tomatoes grown in protected areas.
During the summer, the solarium becomes the hottest place in the garden, and the air in it can warm up. In the absence of ventilation, the temperature in greenhouses and solariums can reach 40 ° C or more.
At the same time, tomato pollen is already sterile at 30-32 ° C. This means that you have flowers, but they cannot be pollinated, even if there are pollinating insects in the solarium or in the garden.
To avoid abortion of tomatoes, plants should be shaded with white matter laid under the roof of the solarium and along the south wall. You should also ventilate the solarium regularly and put more containers of water in the growing space. You need to keep in mind that the ideal temperature for tomatoes is 20-25 ° C.
If you have tomatoes in the garden, try to protect the plants from the scorching sun of the day. Use clay or any other means that can shade the crop on hot days.
Why do tomatoes abort? Reason: high humidity in the greenhouse
In terms of humidity, even this is not so simple – it should not exceed 70%. Otherwise, pollen on tomatoes becomes ineffective. Therefore, you need to water tomatoes rarely, but abundantly, in the morning and under the root. Furthermore, mulch the soil to reduce evaporation.
Tomatoes do not like condensation, which becomes a breeding ground for bacteria. Therefore, it is desirable to have a thermometer in the greenhouse, but also a hygrometer and to always monitor the temperature and humidity level.
Why do tomatoes abort? Reason: lack of vaccination
One of the reasons for aborting tomato flowers is a lack of pollination. The problem occurs especially with tomatoes in the solarium, when it is closed and insects cannot get into it. In this way, pollination is impossible. If you can’t attract bees, bumblebees, and other beneficial insects and don’t have time to aerate, you’ll need to act as a pollinator.
In the morning and evening, you need to gently shake the flowers so that pollen falls on them.

Why do tomatoes abort? Reason: too many kids
By nature, tomatoes are perennial, so they try to last all year round, not suspecting that in our latitudes they are given a maximum of six months. The plant focuses not only on the formation of tomatoes, but on the growth of green mass.
The more organic matter and mineral fertilizers you use with nitrogen in the soil, the more active the plant will grow, and it will have more branches and children.
In the case of tomato bushes, you will need to remove most of the leaves and keep 1-3 main stems (depending on the variety). Shoots extract nutrients from the mother plant, so fruit formation will be delayed indefinitely. So, childhood is a business that will help you get tomatoes, and not just flowering plants.
Why do tomatoes abort? Reason: boron deficiency
Boron stimulates flowering, promotes pollen germination, fruit and seed formation. Therefore, a lack of boron significantly reduces the productivity of the plant. But the concentration of boron in the soil is too low, and then plants will have a hard time absorbing this chemical. So it is better to supplement the intake of boron, for example, by foliar fertilization.
To stimulate the appearance of ovaries in tomatoes, every 10-14 days, it is necessary to spray the plant with a solution of boric acid, dissolving 5 g per 10 liters of water.
Tomatoes, strawberries and apples suffer the most from boron deficiency.
