We all would like to see fresh tomatoes on our table. It is a pity that the climatic conditions in our country do not allow us to grow tomatoes all year round. Fresh vegetables run out with heat.

You can buy crops at the store, or you can try to grow a lot of large red vegetables yourself in the greenhouse.

In this article, you will find step by step instructions on growing tomatoes and preparing a greenhouse. And you will also learn a few secrets to get a good harvest.

Agricultural technology for obtaining vegetables in greenhouse conditions: pros and cons

Undoubtedly, one of the main advantages of this procedure is getting an early or even year-round tomato harvest. In addition, since the culture is planted in isolation from the external environment, it is not threatened by diseases and pests.

Plus, other external factors do not affect the harvest:

  • air temperature;
  • humidity and precipitation;
  • contaminated air.

If, nevertheless, pests were found on plants, it will be much easier to deal with them in an enclosed space. But also the main argument for adherents of natural products - greenhouse crops are absolutely safe and nitrate-free... While no one can guarantee the quality of store products.

However, with all the advantages, such cultivation also has some disadvantages. It should be said that in terms of taste, the greenhouse tomato is inferior to the tomato grown in the open field.

Reference! The main disadvantage of all greenhouse structures is increased flammability, so it is very important to monitor fire safety.

If you build a greenhouse according to all the rules, then the cost of such a structure will be rather big, which means that the tomatoes themselves will not be cheap, but you will be completely sure of their quality.

Tips for preparing film construction

The manipulations for the preparation of greenhouse structures for spring planting include the following actions:

  • cleaning and renovation work (remove the remnants of last year's crops and weeds;
    the greenhouse is inspected for damage and eliminated);
  • greenhouse disinfection (for this, you need to dilute 3 kg of slaked lime and 0.5 kg of copper sulfate in 10 liters of water; treat with the resulting solution all surfaces of the greenhouse structure, as well as all pegs for tying crops);
  • increasing soil fertility (for this, 15-20 cm of the upper soil layer is changed annually to a new one, and then EM preparations are introduced into the soil).

How to grow properly: step-by-step technology

Planting seeds for seedlings

Before planting, the seed must be processed in a weak solution of potassium permanganate for 20-30 minutes. After extraction, the seeds must be rinsed and dried. It is better to plant tomatoes in ready-made soil... Be sure to place a drainage layer on the bottom of the container.

Seedlings can be grown in small plastic cups, trays, or a large shared container. Before sowing, the soil must be moistened. With a pencil, make indentations in which you need to put two seeds each, in case one of them does not germinate. Cover the container with foil and place in a warm, bright place.


To properly care for tomatoes, you need to light the seedlings for 12-13 hours a day. The first few days the air should be warmed up to 23-25 ​​degrees Celsius. After the first shoots appear, the temperature should be reduced to + 16-20 degrees. The night air should be about 5 degrees cooler than the day air.

It is often necessary to moisten the soil - tomatoes do not like drought... This must be done very carefully so as not to damage the fragile sprouts. Choose water for irrigation that is separated, the optimal temperature for growing tomatoes is room temperature.

As soon as even small seedlings sprout, make sure that water does not get on their leaf plates - this can lead to decay.

Air humidity should be within 60-70%.


After planting seedlings in the greenhouse, they need to provide the most comfortable that the seedlings survive stress more easily. Is it possible to transfer seedlings to a greenhouse - it is possible, but only when the air in it warms up to at least +15 degrees. It is advisable to warm up the soil before this procedure.

Experienced agronomists advise planting tomatoes at a distance of 30 centimeters from each other, and retreating at least half a meter between the rows.

Tying and pinching

Tall varieties are most often planted in greenhouses., since they take up as much space as undersized ones, and give a little more yield.

Before starting this procedure, remember a few rules:

  • you need to tie up a tomato as it grows;
  • support is necessary not only for the trunks, but also for the rest of the branches;
  • you cannot knit the fasteners tightly.

In no case do not use fishing line, thick thread or wire for tying... Since the tomatoes will rest on the support with all their weight and because of this, they can be damaged.

The most suitable type of support is a soft wide rope, strips of cloth or plastic. As a support, you can use pipes made of metal and plastic, wooden sticks. The frame itself is pulled onto the same supports.

Stepsons are shoots that are superfluous. They begin to get rid of them two weeks after planting the seedlings in the greenhouse and then repeat this procedure every 15 days. There should be no more than 3 stems on the shoot, which are responsible for the formation of the form, and no more than eight flower brushes.

You can get rid of your stepson as soon as he reaches 5 centimeters in length... It is best to simply break off the shoots, not cut them off. But you should not completely break them, we recommend leaving hemp up to two centimeters long, which will prevent the appearance of new stepsons.

This can be done in two ways: natural and artificial. Natural pollination is about creating air movement and attracting insects. For the first process, in windy conditions, open the windows and doors of the greenhouses so that a draft forms.

And in order to attract insects, you need to plant flowers in the aisle... It is advisable if these are marigolds, since they not only attract insects, but also improve the taste of tomatoes.

Artificial pollination methods include the following manipulations.

  • Shaking... You can carry out this procedure with each bush separately. And if the tomatoes are tied under one support, it is enough to knock on it, and then the reaction will reach all the bushes.
  • Fan... It needs to be worn between cultures - this way you get a draft effect.
  • Brush application... With its help, you can transfer pollen by hand.

How to water and feed, how often?

After the agronomist has just transferred the seedlings to the greenhouse, they do not need to be watered for a week. And then the soil is moistened every five days. The first fertilizer is applied after the first leaf appears. This should be foliar feeding.

Potassium monophosphate is best suited (a tablespoon of the drug is diluted in 10 liters of pure water).

After a week after the first feeding, tomatoes can be fertilized with the following preparations:

  • Urea.
  • Calcium nitrate.
  • Potassium nitrate.
  • "Aquarium".

Collection rules and storage methods

You need to pick slightly unripe tomatoes - they will have a light brown tint. A few days later they will arrive in crates. You need to pick tomatoes together with the stalks - this will preserve all the minerals and nutrients. Store the harvested crop in wooden boxes with openings for air circulation. Thick paper should be under each layer of tomatoes.

Secrets of growing large sweet tomatoes from A to Z

Early in an unheated room

To do this, you need to add compost to the soil in the fall. For early planting, you need to choose the place where cucumbers used to grow, since after them the soil will be saturated with manure. Before planting, you need to add wood ash and fertilizer for tomatoes, as well as 10 superphosphate granules to each hole.

Indeterminate varieties

In the process of growing such crops, the most important thing is to tie up the bush in time, and also pinch it in order to stop its growth upwards.

Tomatoes are grown and pinched depending on the height of the bush... You also need to apply a lot of fertilizer, since large dimensions require good nutrition.

In the Kuban

The weather conditions in this region make it possible to harvest tomatoes almost all year round. The air temperature in the local greenhouses rarely drops below 3 degrees Celsius - many varieties can still withstand such indicators. Therefore, do not be afraid to plant tomatoes before winter, the main thing is to provide good lighting.

No watering

In order not to water the tomatoes throughout the season, it is enough to try once and provide them with the necessary conditions. To do this, before planting, you need to remove all the leaves from the lower half of the trunk. The hole should be deep. They put half a bucket of compost in it, a handful of wood ash and a gram of potassium permanganate - mix all this and pour 5 liters of water.

After absorbing moisture, the seedlings are placed in the holes almost horizontally and sprinkled with a small layer of soil. Once again, water each bush with a bucket of water. This is enough for the whole season. As soon as the stem grows up, its top must be tied vertically.

All year round

If we talk about large-scale production, then in order to get tomatoes all year round, you need to properly equip the greenhouse: provide electricity, make ventilation, install an irrigation system, put in climate control.

Compatibility with other cultures

A tomato will be great if you plant any kind of salad, onion, parsley and even a watermelon next to it. but do not place cucumbers, fennel and dill next to tomatoes.

Growing tomatoes in a greenhouse is troublesome. However, it is pleasant when you can treat someone with a fresh vegetable at any time, and profitable if this vegetable can be sold.
