Tomatoes are very popular in our country. A rare gardener does not cultivate this tasty and healthy vegetable crop in his country or home garden. The highest yield of tomatoes is shown in a greenhouse or greenhouse. It makes no sense to make any special conditions for the cultivation of this crop, but it is simply necessary to observe the basics of the cultivation technology. Otherwise, the plants do not give the proper volume of the crop, and sometimes they simply “fatten”.
Tomatoes cultivated in a greenhouse or greenhouses are sometimes very capricious. The slightest changes in indicators of temperature, humidity or lighting can provoke various deviations in the growth and development of plants. Of particular importance is the mode and quality of fertilizing, as well as the qualitative composition of the soil.
Greenhouse soil is prepared from the fall. Digging, disinfecting and fertilizing are part of the standard procedure. However, some gardeners neglect these rules and postpone the main preparation of the planting area in the greenhouse for planting tomatoes in the spring. It is possible to determine the presence of deviations in the vegetation of this vegetable crop not only by external signs, but also by a significant decrease in yield.
From the side, bushes of “fattening” tomatoes in the greenhouse look quite attractive. Tomatoes in this case are very powerful and well developed. The leaves on a plant cultivated in a greenhouse or open ground have a very bright dark green color and are characterized by juiciness. The apical leaflets tend to curl.
Such a massive bush will not give a high-quality and abundant crop, which is due to the redistribution of the flow of nutrients from the forming ovaries and fruits into the green mass of the plant. Characteristic features will be the presence of an underdeveloped flower brush and a small number of flowers on the cultivated plant. However, there is a massive growth of vegetative mass.
Of course, it is impossible to draw hasty conclusions and reject such tomatoes. It is necessary to carefully examine all the plants in the greenhouse and identify the root cause of the problem.
Another type of fatliquoring tomato in the greenhouse is the formation of new shoots. This type of physiological disease is formed on indeterminate tomato varieties and hybrids with a long flower brush on which fruit sets. There will be practically no harvest from such greenhouse tomatoes.
Causes of occurrence
Greenhouse tomatoes are very responsive to quality and regular care, as well as timely top dressing. However, if you make fertilizer application excessive, then the plants "fatten". Tomatoes cease to accumulate nutrition in the ovaries, as well as fruits, and redistribute the entire flow of substances necessary for abundant fruiting to the green parts of the plant.
In addition to excessive fertilizer application, “fatliquoring” and plant growth in the greenhouse can be triggered by high levels of air humidity, as well as too frequent or heavy irrigation. Equally important is the correct and sufficient illumination of greenhouse plants. Tomatoes react very actively to low light.
Why do tomatoes "fatten"
It should be remembered that tomatoes with a short brush, as well as determinant varieties of tomatoes, are practically not affected by the manifestations of such a disease.
The main reasons that greenhouse tomatoes “fatten” can be determined by some circumstances.
- The most common and most common reason for "fattening" a tomato in a greenhouse is due to overfeeding of plants with nitrogen fertilizers, which provokes the growth of green mass in a vegetable crop to the detriment of quality fruit production.
- Too frequent watering in the first fifteen days after planting seedlings in a permanent place in the greenhouse soil. Such overmoistening is very harmful to the formation of a strong and healthy root system, and also contributes to the surface growth of roots. In addition, against this background, a decrease in the resistance of tomatoes to adverse external influences can be noted.
- Excessive introduction of manure or bird droppings at the vegetation stage quite often causes tomato "fatliquoring".
- The increased growth of tomato bushes is facilitated by frequent irrigation throughout the growing season, as well as excessive humidity in the greenhouse.
- Another important factor is too thick planting of greenhouse plants in combination with a lack of light.

How to fix the problem
There are several ways to quickly get rid of greenhouse tomatoes from this phenomenon. PAt the first sign that the tomatoes in the greenhouse are “overweight”, the following measures should be taken.
- It is required for at least a week to stop the irrigation of tomatoes in a greenhouse or open ground.
- Performing foliar feeding using phosphorus fertilizers. A very effective means is the use of superphosphate.
- The introduction of extracts of superphosphate at the rate of three tablespoons per bucket of warm water under the root of cultivated plants. Root top dressing is carried out after heavy watering. The standard dose of the solution is about one liter per plant.
- A very important nuance is the complete exclusion of nitrogenous fertilizers from top dressing.
- An increase in daytime temperatures inside the greenhouse to twenty-five degrees.
- Monitoring night temperature indicators, the optimal parameters of which should not exceed twenty-two degrees.
- Carefully, but extremely carefully remove from the plants that part of the leaves that interferes with the full lighting of tomatoes.
- Remove all leaves that are located above the flower brushes and cover the forming ovaries from lighting.
- High-quality phosphate fertilizers comprise about thirty percent of potassium and fifty percent of phosphorus. These components belong to the category of instant ones, which makes settling the solution prepared for spraying impractical.
Foliar top dressing is very effective as an ambulance for "overweight" plants, however, to consolidate the result, spraying with root top dressings should be supplemented. Such a measure will allow the plant to delay the growth of green mass and redistribute nutrients to the ovaries and fruits of tomatoes.
The most effective are preventive measures, the implementation of which does not require significant efforts from the gardener. Most often, it is enough to adjust the microclimatic conditions in the greenhouse, as well as observe the main stages of the technology for growing greenhouse tomatoes.
How to water tomatoes in a greenhouse
A good preventive measure can be the introduction of ordinary wood ash, which is rich in potassium and does not allow plants to "overweight". In addition, periodic inspections of plants should not be neglected, and when the first signs of a change in the appearance of tomatoes are detected, it is necessary to carry out the above measures as soon as possible.
