Compared to other crops, the tomato is a hardy plant that can forgive many care mistakes and reap harvests later. But in order to achieve the maximum result for your spent efforts, you need to focus on some important points of care. This will help you understand why tomatoes are blooming, but not tied, what to do in this case in order to get a decent harvest.

Before proceeding with the elimination of the problem, you should understand each case.

Lack of sunlight

Often the reason why there is little color on tomatoes is the thickening of the plantings in the greenhouse. As a result, the bushes form a shadow to each other, which prevents a full fruit ovary. Sometimes sunlight does not pass to the lower tier of the shoots due to the abundant foliage.

This occurs as a result of a disruption in the process of photosynthesis, since in the absence of a sufficient amount of light, the plant cannot make a supply of nutrients for flower brushes and therefore gets rid of them like unnecessary ballast.

Lack of vitamin D

Important! The main condition for the successful cultivation of tomatoes in a greenhouse is the correct arrangement of varieties, that is, low-growing tomatoes should be placed on illuminated rows, and tall ones behind them, which will help to avoid shading with each other.

Improper watering

In some cases, the answer to the question of why tomatoes are not tied lies in improper watering. For example, sparse irrigation leads to drying out of the root system and, as a result, the flowers are discarded.

The problem can be provoked by the introduction of cold water from a hose under the root of tomatoes. In this case, the plants receive a certain stress, since they are not able to perceive moisture at low temperatures with a high salt content. This is especially critical at the height of a hot day, when the contrast is very noticeable for tomatoes. As a result, the ovary and peduncles fall off, since the plant is in a stupor after such a shake-up. This is critical both for tomatoes in the open field and in the greenhouse.

Lack of nutrition

Sometimes the reason why flowers and ovaries fall off in tomatoes is a lack of essential nutrients, namely phosphorus and potassium.

Excessive enthusiasm for organic fertilizers such as chicken manure, manure leads to an uncontrolled build-up of green mass, which also contributes to barrenness and shedding of the ovary. This is due to the fact that the bushes do not receive the necessary nutrition for the maintenance of flower brushes and fruits.

Lack of water

Temperature regime

Sharp temperature fluctuations can also be the reason why there is no full-fledged tomato ovary in the greenhouse. The most dangerous is a sharp decrease or increase in temperature within 10 degrees. In this case, the plants cannot quickly cope with the load and therefore react to the shock by dropping the ovary.

Note! It is very important that the nighttime temperature does not fall below 15 degrees, as at this time of day the pollen ripens, which makes it possible to pollinate the ovary pistil in the morning.

No pollination

Tomatoes are considered a self-pollinated crop, but when the temperature in the greenhouse rises above 36 degrees, fruits that do not contain seeds are formed, and as a result, the plant recognizes them as unable to produce offspring and abruptly discards them.

The reason why tomatoes do not set very well may be prolonged cloudy weather. This leads to the fact that pollen becomes incapable of pollination due to lack of sunlight.

Diseases and pests

The most dangerous reason why flowers fall off in tomatoes in a greenhouse is an attack by pests or a fungal infection. This often happens when you ignore the soil disinfection procedure before planting tomatoes or when a large amount of manure is introduced into the soil.

The main enemy

As a result, both the aerial part of the plant and the root system are damaged, which leads to a lack of nutrition and a sharp drop of the ovary.

What to do if flowers fall from tomatoes

Having found out the reason why tomatoes are not tied in the greenhouse, it is necessary to decide what to do first and how to improve the formation of fruits. Several effective methods should be taken and then the result obtained will exceed all expectations.

Lighting adjustments

To improve the access of light to the lower tier of flower brushes, you should remove excess leaves and carry out the timely formation of the bush in one or two shoots. In addition, it is important to correctly place tall and low-growing varieties so that they do not create shadows towards each other.

In this situation, the only way out can be the maximum breaking off of the foliage, as well as the installation of additional lighting using phytolamps.

Proper watering

To prevent further dropping of the ovary in tomatoes in the greenhouse, you can also adjust the watering.

Important! Soil moistening should be carried out in the morning or in the evening, this is the optimal mode for tomatoes.

For irrigation, use warm, settled water. If the soil dries up due to a prolonged lack of watering, you should first loosen the soil in the greenhouse and then moisten it. This method will prevent the ovaries from falling off the bushes and will improve moisture access to the roots.

The increased humidity in the greenhouse also leads to the dropping of flowers in tomatoes, what to do in this case, the gardener should know in advance. An increased level of moisture in the air causes the pollen to swell and lose its fertility. Therefore, it is worth regularly ventilating the greenhouse and postponing watering in the morning, which will help maintain an optimal climate for plants and prevent the appearance of fungal diseases.

Boost immunity

It is possible to increase the resistance of tomatoes to the effects of external negative factors by processing with special preparations.

  • Zircon... The drug helps to activate the vitality of the plant, which reduces susceptibility to temperature changes. Processing should be carried out on the leaf during the budding and flowering period, evenly spraying the green mass in a proportion of 1 ml per 10 liters of water.
  • Epin... This agent is an antidepressant and helps plants to cope with stress without negative consequences. The drug is sprayed over the leaves when the temperature is likely to drop significantly. The working solution is prepared in a ratio of 1 ml to 1 liter of water.

Top dressing

In order for the tomatoes to bloom and the ovary does not fall off, it is necessary to introduce nutrients such as phosphorus and potassium.

Important! It is necessary to fertilize tomatoes in moderation in order to maintain a balance between the capabilities of the plant and the load, therefore, periodically, the bushes should be gently shaken to make it possible to get rid of excess inflorescences.

During the budding period, root phosphate-potassium dressing should be carried out using 20 g of superphosphate and 15 g of potassium sulfide per 10 liters of water. And during the ovary of fruits, tomatoes should be fertilized at the rate of 25 g of potassium sulfide per 10 liters of water.

You can replace these drugs with a folk remedy based on wood ash. For this, it is necessary to prepare a hood based on this component.Pour 100 g of ash with 1 liter of boiled water, leave for 1 day. Then add 9 liters of water, mix and spray the bushes.

We fertilize the soil

Additional pollination

It is possible to prevent the shedding of the ovary with the help of additional pollination of flowers by insects. Therefore, during the flowering period, you should ensure that the door to the greenhouse is constantly open.

In addition, to attract pollinating insects, you can spray tomatoes with a sweet solution, adding 100 g of sugar to 10 liters of water.

Note! Use warm water for processing so as not to add additional stress to the tomatoes.

You can improve the flowering and ovary of tomatoes with the help of special stimulants.

  • Bud- a natural stimulant that helps to reduce the number of barren flowers and increase the number of ovaries. To prepare a working solution, it is necessary to dissolve 10 g of the drug in 10 liters of water.
  • Ovary- a universal biological preparation that promotes the formation of fruits with partial pollination or in its complete absence. To do this, spray the bushes at the rate of 2 g of the product per 1 liter of water.

Pest and disease control

An important factor is the preventive treatment of bushes from diseases and pests.

Common diseases and pests that provoke the discharge of the ovary.

  • Verticillary withering... The disease is characterized initially by wilting of the lower leaves at the base. And then the process moves on to the upper shoots and flower brushes. To combat the disease, it is necessary to loosen the soil after each watering to a depth of 10 cm, as well as carry out top dressing on time and prevent the soil from overheating.
  • Vershinnaya rot... The disease is characterized by damage to the fruit, and as a result, it provokes the discharge of the ovary against the background of the oppressed state of the bush. You can fight the disease by carrying out an extraordinary feeding with a high potassium content.
  • Spiderweb mite... The pest is invisible to the naked eye. A characteristic sign of tomato damage is yellowing of the leaves along the outer edge, a significant slowdown in growth and a sharp drop in flowers. You can cope with the pest with the help of drugs: Actellik, Fufanon.
  • Whitefly... The insect looks like a small white midge in appearance. You can notice the pest on the back of the sheet. The massive accumulation of insects leads to oppression of plants and a stop in development. It is necessary to fight the pest in a comprehensive manner, watering the bushes with Aktara and spraying with Aktellik.
  • Aphid... It is a small green or light colored insect that feeds on plant sap. It is localized on the back of leaves and young shoots. Affected shrubs can be recognized by deformed leaves and dropping of the ovary. You can get rid of the pest using such means as Karate Zeon, Aktofit.

Falling flowers in tomatoes is a common phenomenon that must be dealt with. Knowing why the ovaries of tomatoes fall off, you can take action in time and get a generous harvest.
