The process of growing tomatoes in a greenhouse has some peculiarities, if you take them into account, you can get an excellent result. Many gardeners are concerned about the question: planting a tomato in a polycarbonate greenhouse, where to start?

Soil preparation

Greenhouse soil preparation under the tomatoes in the spring is a very important event, because with improperly prepared soil, the plants will not give a good harvest and will constantly hurt. It will be best if you remove the top layer of soil (about 10 cm), and pour copper sulfate on the renewed soil for tomatoes in the greenhouse (1 tablespoon per bucket of water). After that, be sure to ventilate the room.

Then you should dig up last year's beds with humus and close the greenhouse before planting the tomatoes. Such processing before planting tomatoes is simply vital.

Important! Fresh manure cannot be used as fertilizer!

In no case should you plant tomatoes in the same greenhouse for more than 2 years in a row! Most infections remain in the ground anyway, and new plants will become infected.

Due to poor frost resistance, tomatoes need to be transplanted on the heights... The beds, the height of which should be about 40 cm, must be formed about 1.5 weeks before planting seedlings on them.

Reference. The maximum acceptable age of seedlings for transplantation is about one and a half months, at the end of this period the seedlings have an optimally mature root system.

General landing rules

So, how to plant tomatoes in a polycarbonate greenhouse correctly? The main thing is to follow a few simple rules.

    • choice of the day;

A cloudy day is considered a good day for planting. If the day is sunny, then it is better to plant in the late afternoon to reduce stress from the hot sun. The soil when planting plants should be well warmed up.

    • planting depth;

The root should be completely in the ground, but the growth point should not be closed - it is about 15 cm deep, it will be good to put humus or other fertilizer in the grooves.

Remove yellow and cotyledon leaves at ground level before planting. Need to compact the soil around the plant and sprinkle with soil. To prevent diseases such as late blight, each plant can be sprayed with copper oxychloride (40 g of copper per bucket of water).

    • watering.

After the transplant, you need water abundantly tomatoes, under each bush. Further, it is better not to water the plants for a week, since otherwise all development will go to the growth of the stem. In the future, it is worth watering the tomatoes rarely, but abundantly, preferably in the morning.

It is very important to choose a specific the order of planting seedlings tomatoes, depending on the varieties. And also decide which tomatoes to plant, when to plant and at what distance.

Important! Crops after which it is impossible to plant a tomato are all nightshade: tomatoes, eggplants, peppers, physalis, and for example, after cucumbers and potatoes, on the contrary, it is necessary.

Tomatoes in a polycarbonate greenhouse: planting scheme

  • two-row, which means that the width of the bed should be about 1.5 meters, and the length - as much as you like, taking into account the fact that the distance between the plants should be about 30-60 cm.
  • checkerboard - planting bushes in 2 rows, with an interval of about 50 cm, at a distance of 30-40 cm from each other with the formation of 2-3 stems. This scheme is suitable for undersized early maturing varieties.
  • staggered order, but for tall species, every 60 cm with a distance of 75 cm between the rows.

Important! You need to plant prepared seedlings in a greenhouse. Preparation takes place by hardening - taking seedlings outside in a warm time of the day for about 2 hours.

2-3 days before planting, the seedlings, if they are in separate containers, need to be watered, it will be more convenient to remove them during transplanting. And the seedlings that grow in a common container, on the contrary, stop watering in 2-3 days, and watered abundantly just before the transplant.

How to plant tomatoes in a greenhouse: distance

Planting tomato seedlings has its own specific algorithm. In order not to be mistaken in distance between plants, study the packaging from the seeds, planting in the ground will be most accurately described there. In any case, you should not plant more than 30 cm apart and no further than 80 cm.When the distance is too small, the tomatoes will wither from lack of nutrients, and with a large distance there will be a small crop and the fruits will grow and ripen more slowly ...

Greenhouse landing

For a better harvest, you should consider not only the placement of the tomatoes, but also the correct date for planting the tomatoes. First of all, you need to wait for the most constant warm weather.

  • plants can be planted in a heated greenhouse from April 29;
  • to an unheated greenhouse, but with a double film layer - from May 5;
  • to an unheated and not insulated greenhouse - from May 20;
  • in open ground, but with a film coating - from May 25.

The air temperature, on average, when planting in a greenhouse should be about 25 ° C.

Reference. To improve the quality of the yield, the plants should be fed every 20 days with mineral fertilizers, and after transplanting, 10 days later, the first feeding should be carried out (half a liter of liquid mullein, 1 tablespoon of nitrophoska per 10 liters of water), and about a liter of fertilizer should be used for each bush ...

Which greenhouse to choose?

An important factor in improving productivity is also the material from which your greenhouse is made.

Now the more popular coating materials are polyethylene film and polycarbonate.

Polycarbonate - the material is not cheap, but durable and does not wear out immediately, unlike film. Although it perfectly protects plants from ultraviolet radiation, it is more suitable for winter heated greenhouses due to its thermal insulation properties, but for summer greenhouses, polycarbonate is not particularly needed and will not pay off.

And the temperature in such structures will be simply unbearable for plants on hot days, and even ventilation holes will not help. You will also have to insulate the soil in the greenhouse for the winter, otherwise it will freeze.

Have film coating there are significant advantages over polycarbonate.

  • it is easier to cover the greenhouse with a film, and in case of a breakthrough, it is easy to replace;
  • in winter, since the film is removed, you should not think about covering the soil, snowdrifts will do an excellent job with insulation;
  • film is a cheap material, albeit quickly deteriorating.

Principled difference between these two materials- number of harvests, in a polycarbonate greenhouse, you can plant tomatoes earlier and several times, and therefore you can harvest more often.

Reference. Plants such as tomatoes require loamy, neutral or slightly acidic soil that is well ventilated.


Growing tomatoes is not an easy task even for experienced gardeners; planting tomatoes in a greenhouse requires a competent approach. However, if you adhere to the basic rules and tips, you can get good results even for a beginner.
