Tomatoes fatten what to do. Why tomatoes fatten in a greenhouse and in open ground and what to do. Tomatoes are fattening in a greenhouse: general information, external signs, causes, ways to eliminate the problem, preventive measures, video

Fattening of tomatoes is a common phenomenon, especially for greenhouse tomatoes. IN comfortable conditions the plant stops caring about reproduction and begins to grow lush foliage, a stem two fingers thick and a bunch of unnecessary branches. In this case, the setting of tomatoes either does not occur at all, or it is delayed for a long period. What to do if tomatoes become fatty, and, in fact, why tomatoes become fatty – we’ll talk.

Powerful stems, bright green leaves curled inward, prolonged ripening of fruits - the main signs of fattening tomatoes

Tomatoes fatten: main reasons

Tomatoes fatten for two main reasons:

- overfeeding nitrogen fertilizers

- incorrect, too frequent watering.

For tomatoes there is iron rule: better “under” than “over”. , and other organic fertilizers, as well as nitrogen mineral fertilizers– this is wonderful, but everything should be in moderation. Organic matter is rich primarily in nitrogen. Nitrogen is the strongest stimulant for the growth of green, vegetative mass. The application of nitrogen fertilizers instead of phosphorus and before flowering of tomatoes has a negative effect.

With an excess of nitrogen, all the plant’s forces go into the greens, and the tomatoes fatten, that is:

-the stem becomes unnaturally powerful and thick

- leaves acquire dark green color, twist

- grows a large number of new shoots and stepchildren

- the tomato produces a weak flower cluster with few or no flowers

- tomato ripening is delayed

Frequent watering is another disservice you can do to tomatoes. Due to frequent watering, the plant relaxes, increases surface root system and cannot fully on our own, provide food. Therefore, tomatoes need to be watered rarely (once every 5-7 days, or less or more often, depending on the weather), but abundantly. In the first 15-20 days of life, the young plant does not need to be watered at all: the water that you pour into the hole is quite enough to support the life of the plant. A slight water “starvation” will only make the plant stronger and allow it to grow a powerful root system.

Tomatoes are fattening: what to do?

Overfed tomatoes You can’t return it to its original state, but you need to try to direct the plant’s forces in the right direction, that is, into the formation of fruits.

What can you do if your tomatoes become fat:

1)Eliminate nitrogen fertilizing, replacing them with phosphorus and potassium. Before flowering, add phosphorus-containing additives, as well as a little potassium (potassium will slightly inhibit the supply of nitrogen, besides, this element for tomatoes is a signal for the formation of ovaries. Potassium fertilizers for tomatoes are best done after the 5-6 clusters bloom) and magnesium. As a phosphorus fertilizer, you can take superphosphate - dilute 3 tablespoons of fertilizer in a bucket of water and feed each bush with 1 liter of the composition. The same solution, only twice as weak, should be applied to foliar feeding of tomatoes, that is, treated with a sprayer. You can feed fatty tomatoes with ash.

Nitrogen is mobile element, therefore on light, sandy soils it can be wash out of the soil. To do this, ONE TIME, but with a large amount of water (a bucket and a half for 1 bush), “wash” the soil of nitrogen, and it will be washed into the deeper layers of the soil. After this, the plant is not watered for about a week, gradually accustoming it to a water-free diet. But on heavy ones, clay soils, for obvious reasons it is better not to conduct such experiments.

Will slightly weaken the effect of ordinary nitrogen loosening the soil(extra ammonium will escape into the atmosphere).

The rapid growth of obese tomatoes will help calm down removing bottom sheets, and shoots located above the inflorescences that shade Sun rays tomato brushes. It is recommended to remove one, maximum 2-3 large leaves below the first flower cluster once - this stress will be enough for the tomato to switch to fruit production.

If tomatoes are fattening, it means that they are already behind the normal ripening cycle and are unlikely to feed all the ovaries. Therefore it is possible thin out the flower brush, removing excess ovaries, and also decapitating the bush by pinching the top.

Fattening tomatoes need help with pollination– just gently shake the plant, holding it by the trunk.

Thanks to these simple techniques, overfed tomatoes will restore balance. minerals, previously “skewed” towards increasing green mass.

More information

A change in humidity level or a slight temperature difference leads to tomatoes fattening in the greenhouse. At the initial stage, the problem may not remind you of itself, but behind the apparent calm a real storm is gathering. Don’t think that only novice gardeners face this problem. Even among professionals, seedlings do not always retain their original health.

How tomatoes fatten in a greenhouse: external manifestations

There are several external and internal signs that allow you to suspect something is wrong. No specialized agricultural education is required here. The main thing is to carefully monitor the plant growing process. The first and quite striking symptom is the curling of tomato leaves. In second place in terms of frequency of occurrence is the underdeveloped flower raceme.

Due to the unnatural redistribution of the flow of nutrients from fruits to leaves, the latter receive an excess amount of vital energy.

As a result, from the outside it seems that the leaves are characterized by a rich green And large size. Despite its external attractiveness, one cannot count on a good harvest. After some time, the “overgrown leaves” curl.

In addition, there are several other signs of impending danger:

• Active growth of secondary vegetative mass;
• Constant increase in the number of secondary shoots;
• Reducing the number of flowers produced.

Beginners should remember that the appearance of even one of the listed signs should not be perceived unambiguously. The situation is always considered comprehensively. The more carefully the seedlings are examined, the easier it will be to detect the true culprit. It happens that tomatoes become fattened due to attack by pests or due to lack of natural light.

Why tomatoes fatten in a greenhouse and what to do

Proper care of seedlings involves regular watering, applying the required amount of fertilizer, and so on. Unfortunately, even with strict implementation of the listed recommendations, problems cannot always be avoided. First you need to understand that tomatoes are very capricious representatives of the plant world.

The list of the most common factors that negatively affect the growth activity of tomatoes in a greenhouse opens high humidity air. It is formed against the background external factors, for example, the proximity of a body of water or prolonged precipitation.

In addition, the cause should be sought in frequent watering. The tomato belongs to the category of vegetables for which it is better to give a little water than to water it in excess.

In addition to the listed factors, the reasons for the resulting “fatification” should be sought among the following problems:

• High density of seed planting;
• Watering occurs more often than once every 2-3 days;
• Too active feeding;
• Excessive application of nitrogen-containing fertilizers.

The last point needs to be discussed in more detail. Not all summer residents know exactly how to handle this substance.

Tomatoes in a greenhouse are heavily fattening: what to do about the problem

Refusal of nitrogenous fertilizers is the most common advice from experts if tomatoes are fattened in a greenhouse. After this, the leaves located above the formed ovaries are carefully removed. Otherwise, future fruits will not develop due to lack of sunlight. Therapy for affected seedlings begins with adding a small amount of phosphorus-based fertilizer to the soil.

After this, you need to do the following:

1. Add superphosphate extract.
2. Apply potassium-based fertilizers.
3. It is imperative to increase the average temperature in the greenhouse to 24-25 degrees. In addition, it is recommended to install a temperature sensor that can monitor temperature fluctuations at night.

In addition to all of the above, it is necessary to completely stop watering and applying fertilizer for a while. It is recommended to do this regardless of the intensity of the manifestations of “fatification”. Otherwise, in 4-5 days the entire harvest will be lost.

The process of fattening tomatoes in a greenhouse: what to do and how to prevent

A common problem that is familiar to many gardeners. Over the past half century, many ways to solve it have been developed. In addition to scientifically based methods, there are many “folk” ones.

Soil preparation in the greenhouse begins in mid-autumn. It all starts with determining the level of soil acidity. Beginners should remember that depending on the region, the mentioned indicator may change down or up.

• Carry out digging;
• Routine soil disinfection;
• Contribute required amount fertilizers;
• Optimize soil moisture levels.

It is not recommended to postpone preparatory stage on spring season. Here, as in the matter of vaccination of people and animals, main role time plays out. The longer the prepared soil sits, the better the tomatoes will feel in it. The validity of this argument has been proven by more than one generation of gardeners, so it is worth adopting it for those who want to avoid “fattening” seedlings.

Tomatoes are very popular in our country. It’s rare that a gardener does not cultivate this tasty and healthy vegetable crop in his garden or garden. personal plot. Tomatoes show the highest yield in a greenhouse or greenhouse. It makes no sense to create any special conditions for growing this crop, but it is simply necessary to follow the basics of cultivation technology. Otherwise, the plants do not produce the required amount of harvest, and sometimes they simply “fatten”.

General information

Tomatoes cultivated in a greenhouse or greenhouse can sometimes be very capricious. The slightest changes in temperature, humidity or lighting can trigger various deviations in plant growth and development. Of particular importance is the regime and quality of fertilizing, as well as the quality of the soil.

Greenhouse soil is prepared in the fall. The standard procedure includes digging, disinfection and fertilization. However, some gardeners neglect these rules and postpone the main preparation of the planting area in the greenhouse for planting tomatoes until the spring. The presence of deviations in the growing season of this vegetable crop can be determined not only by external signs, but also by a significant decrease in yield.

External signs

From the outside, the bushes of “fattening” tomatoes in the greenhouse look quite attractive. In this case, tomatoes are very powerful and well developed. 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 leaves tend to curl.

Such a massive bush will not produce a high-quality and abundant harvest, which is due to the redistribution of the flow of nutrients from the developing ovaries and fruits into the green mass of the plant. Characteristic features there will be the presence of an underdeveloped floral raceme and a small number of flowers on the cultivated plant. At the same time, massive growth of the vegetative mass is observed.

Of course, one cannot draw hasty conclusions and discard such tomatoes. It is necessary to more carefully examine all the plants in the greenhouse and identify the main cause of the current problem.

Another type of “fatification” of a tomato in a greenhouse is the formation of new shoots. This type of physiological disease is formed on hybrids that have a long flower raceme on which fruit sets. There will be practically no harvest from such greenhouse tomatoes.

Causes

Greenhouse tomatoes are very responsive to quality and regular care, as well as timely feeding. However, if you apply fertilizer in excess, the plants become fattened. Tomatoes stop accumulating nutrition in the ovaries and fruits and redistribute the entire flow of substances necessary for abundant fruiting to the green parts of the plant.

In addition to excessive fertilization, fattening and overgrowth of plants in a greenhouse can be caused by high levels of air humidity, as well as too frequent or excessive watering. Correct and sufficient lighting of greenhouse plants is of no small importance. Tomatoes react very actively to insufficient lighting.

Why tomatoes “get fatty” (video)

It should be remembered that tomatoes with a short raceme, as well as determinate varieties of tomatoes, are practically not susceptible to the manifestations of this disease.

The main reasons that greenhouse tomatoes become fatten can be determined by certain circumstances.

• The most common and most common reason for the “fatification” of tomatoes in greenhouses is due to overfeeding the plants with nitrogen fertilizers, which provokes an increase in vegetable crop green mass to the detriment of quality fruit formation.
• Too frequent watering in the first fifteen days after planting seedlings on permanent place into greenhouse soil. Such waterlogging is very detrimental to the formation of a strong and healthy root system, and also promotes superficial root growth. In addition, against this background, a decrease in the resistance of tomatoes to adverse external influences may be noted.
• Excessive application of manure or bird droppings during the growing season quite often causes tomato “fatification”.
• Increased growth tomato bushes This is facilitated by frequent irrigation throughout the growing season, as well as excess air humidity in the greenhouse structure.
• Another important factor is the too thick planting of greenhouse plants combined with insufficient lighting.

Solutions to the problem

There are several ways to sufficiently short time to rid greenhouse tomatoes of this phenomenon. At the first sign that the tomatoes in protected soil have become “fat,” the following measures should be taken.

• It is required to stop irrigating tomatoes in a greenhouse or open ground for at least a week.
• Performing foliar feeding using phosphorus fertilizers. A very effective remedy is the use of superphosphate.
• Applying superphosphate extract at the rate of three tablespoons per bucket of warm water under the root of cultivated plants. Root feeding is carried out after abundant watering. The standard dose of solution is about one liter per plant.
• Very important nuance is the complete exclusion of nitrogenous fertilizers from fertilizing.
• Increasing daytime temperatures inside the greenhouse to twenty-five degrees.
• Night control temperature indicators, optimal parameters which should not exceed twenty-two degrees.

• Carefully, but extremely thoroughly, remove from the plants that part of the leaves that interferes with the full coverage of the tomatoes.
• Remove all leaves that are located above the flower clusters and cover the developing ovaries from light.
• High-quality phosphate fertilizers contain about thirty percent potassium and fifty percent phosphorus. These components are classified as quickly soluble, which makes settling the solution prepared for spraying impractical.

Foliar feeding are very effective as an ambulance for “fat” plants, however, to consolidate the result, spraying with root fertilizers should be supplemented. This measure will allow the plant to delay the growth of green mass and redistribute nutrients to the ovaries and fruits of tomatoes.

Prevention measures

The most effective are preventive measures, the implementation of which does not require significant effort from the gardener. Most often it is enough to adjust microclimatic conditions in the greenhouse, as well as follow the main stages of the technology for growing greenhouse tomatoes.

A good preventive measure may be to apply the usual wood ash, which is rich in potassium and does not allow plants to become fat. In addition, periodic inspections of plants should not be neglected, and if the first signs of a change in the appearance of tomatoes are detected, it is necessary to carry out the measures listed above as quickly as possible.

By appearance plants can be determined about its development, diseases or lack of care, as well as the future harvest. It happens that tomatoes become fattened when all the energy goes into vegetative mass and growth, and you can’t count on fruits.

If tomatoes are fattening, then good harvest you can't wait. Strong and healthy bushes look powerful, the stems are thick, and the leaves are juicy and green. Over time, the upper foliage begins to thicken and curl, which is the main sign of fattening. If you do nothing, then flowering does not form ovaries or does not occur at all, since the brush weakens and stops developing. Sometimes it happens that flower clusters continue to produce new shoots, which take away all the nutritional energy, and the fruits do not form or ripen. A fattening plant bears fruit extremely poorly, and the gardener loses the harvest.

Causes

Among the main reasons why tomato crops become fattened are the following:

• insufficient lighting;
• excessive fertilization with mineral or organic fertilizers, including manure;
• excessive watering and high constant humidity;
• crowded and dense planting of plants in a greenhouse.

It should be noted that determinate varieties of tomatoes with a short raceme do not suffer from shoot growth. Indents with a long flower raceme and hybrid varieties are subject to fatliquoring.

What measures to take

As soon as it is noted that the plant has begun to fatten, it is necessary to urgently correct the situation and do something. It is recommended to carry out a number of agrotechnical measures:

• stop watering tomatoes for a week;
• provide the necessary lighting in the greenhouse;
• feed the bushes with phosphorus fertilizers from superphosphate extract (3 tablespoons per 10 liters of water);
• Feeding should be root feeding so that the plant does not retard its growth, but only in moist soil and no more than 1 liter per bush, and foliar feeding in the form of spraying with a non-settled solution, excluding nitrogen;

• It’s good to add microelements to the feeding, especially magnesium and potassium;
• raise the daytime temperature to 25 – 26°C, and at night – to 24°C;
• remove some of the leaves that block the light above the flower cluster, but no more than 1 leaf in 2 days, so as not to cause stress to the plant;
• force pollination of tomatoes by shaking each bush, but only in dry weather;
• Do not ventilate the greenhouse for 7 days; only in case of extreme heat, it is recommended to constantly keep the windows in the greenhouse open.

Fattening can manifest itself in different ways. If the leaves of a tomato are directed upward, the fruits will be small and the flowers will fall off quickly. This means that the plant has not been watered enough. In this case, ventilation and lowering the temperature in the greenhouse will help increase the yield.

It happens that the bush develops correctly, the flowers do not fall off and the leaves almost do not curl, but the fruits develop well only on the first cluster. Then the tomatoes should be collected while they are not yet ripe in order to improve the formation of fruits on the remaining clusters. Immediately after harvesting, the plant must be watered well - 10 liters for each square meter. The temperature in the greenhouse should be reduced to 17 degrees, and stepsons and leaves should not be removed. In hot weather, tomatoes are grown in open ground because ventilation will not help.

Prevention of fattening

The following preventive measures will help you avoid fat gain:

• treat bushes against pests and diseases once every 2 weeks by special means in low dosage;
• It is not recommended to plant seeds for open soil in a greenhouse;
• be sure to pinch the top and remove the side shoots;
• frequently ventilate the greenhouse during the hot season;
• choose the right variety, paying attention to hybrids that produce 30% more yield in a greenhouse;
• It is not recommended to plant tomatoes together with cucumbers, since the maintenance and care required are different;
• properly tie the bush, wrapping a rope around the stem - make 1 turn per 2 internodes so that the plant does not slip;
• Perform pinching when the shoot height is up to 3.5 cm and do not leave stumps, otherwise the plant will begin to waste nutrients;
• Do not apply fertilizers in advance, especially manure, but monitor the lack of magnesium, and if the leaves turn yellow, feed with magnesium sulfate.

Prevention must be done constantly - this will help avoid fattening of tomatoes and get a good harvest.
