In any climate zone, but especially in regions with long spring frosts and short summers, it is advisable to grow tomatoes in polycarbonate greenhouses. This material transmits heat and light well, but does not allow cold to penetrate into the room, and is distinguished by its low price and plasticity.
In protected soil you can get a guaranteed high yield, however, the requirements for greenhouse tomatoes are special. They should be resistant to most diseases and tolerate high humidity and temperature. Therefore, it will be useful for novice vegetable growers to find out which varieties and hybrids are best grown in polycarbonate greenhouses. This article will provide an overview of the best tomatoes for protected soil.
Ural
Titanic
Titanic tomatoes have been grown in the Southern Urals for a long time. This is a mid-season hybrid variety. The ripening period is 120 days. The height of the bush reaches 44-54 centimeters. Grown only in a greenhouse. It does not germinate and bear fruit well in open beds.

Wonderful lady
In the Siberian region, this hybrid is planted exclusively in a greenhouse. The growth period is 100-105 days. After this time, medium-sized tomatoes with fleshy burgundy-colored pulp appear on the plants.
The Fair Lady tomato is a low-growing plant. The height of the bush reaches 45-50 cm. This feature allows you to do without additional supports and garters. The variety is resistant to most tomato diseases found in the Urals.
Banana legs
A greenhouse hybrid that can be successfully grown in the Urals. It has tasty, yellow, elongated fruits with a pointed end. The taste has a pleasant citrus note. Tomatoes are not prone to cracking, so they are widely used for pickling. Tomatoes appear on the branch 100 days after planting.
The bush grows up to 1 m in height. It does not require mandatory pinching, but experienced gardeners shape the plant up to the first cluster - this allows them to get an earlier harvest.
Pink honey
This variety is characterized by early ripening. The productivity of Rose honey is 3.7 kg/sq. m. Bushes up to 1.5 m high produce a small amount of dark green leaves and up to 6 kg of fruit. The variety is recommended for cultivation with the development of two shoots.
Disease resistance is average. The first tomatoes can weigh up to 1.5 kg, and subsequent ones - up to 800 g. The shape of the fruit is heart-shaped, slightly ribbed. The internal structure suggests the presence of more than 4 chambers. Rose honey has a fleshy, sweet pulp without sourness.
Tomatoes are suitable for consumption only fresh; they are not suitable for canning due to their large size. They are stored very poorly, so it is recommended to use them immediately after collection.
What should be the feeding and garter?
Tomato plants are fertilized with mineral fertilizers and organic matter. Nitrogen is added 2 weeks after planting, phosphorus fertilizer is added during flowering, and potash is added for fruit growth. Fertilize with organic fertilizers after flowering approximately once every six months. You can feed tomatoes with fermented weeds.
Advice from gardeners: to speed up ripening, place a bucket of humus or manure in the greenhouse; the carbon dioxide released will stimulate the filling and setting of fruits.
You need to tie it to a trellis and pull it up as it grows. If you grow large-fruited tomatoes, then provide enhanced support. Do not forget to remove the stepsons from the leaf axils.

And you should choose, first of all, in accordance with your capabilities, and not blindly follow your desires. With the right approach and careful care, any crop can produce a decent harvest. Greenhouse varieties have many advantages, one of which is high yield. However, we should not forget that a greenhouse is painstaking work not only in the three summer months.

Rules of care
Typically, indeterminate tomatoes are grown in polycarbonate greenhouses. Plants need to be provided with timely watering, fertilizing and rooting. Without this, you cannot get a full harvest. With insufficient care, it will be insignificant, and the quality of the fruit will be low.
Watering mode
For tomatoes, the correct humidity level in the greenhouse is important. If you overdo it with watering, the plants may get sick, and if they don’t have enough water, then due to drought the fruits will be of poor quality. For tomatoes, air humidity should be 60%, and for soil - 90%. In such conditions, the bushes will fully develop, and fungal diseases cannot arise.
For tomatoes growing in a greenhouse, watering 1-2 times a week is sufficient. It is important to evaluate not only the level of soil moisture, but also the air. If it is too wet, then you need to postpone the next moistening of the soil a little. To assess soil moisture, you should look at how deeply it has dried. At a depth of 3-5 cm, the soil should always be moist. In order for a sufficient amount of oxygen to reach the roots, after watering the soil around the plant must be loosened.
Important! A good option is to organize a drip irrigation system that constantly maintains an optimal level of soil moisture.
Fertilizer application
Tomatoes are fertilized regularly several times a season. If you ignore them, you will not be able to get a full harvest, since the plants will not have enough strength to lay a large number of ovaries and allow them to fully ripen. This also applies to areas with nutritious soils.
The first fertilizing with nitrogen fertilizers is carried out at the moment of active growth of stems and leaves, as soon as the planted bushes take root. The second application of fertilizer occurs at the time of flowering. Then the tomato’s need for potassium increases. To satisfy it, potassium sulfate is added to the soil. The third feeding is carried out 20 days after the first and an infusion of ash is used for it. When the fruiting period begins, superphosphate is needed. It is embedded in the soil under the bushes and then watered. The granules dissolve slowly, so they nourish the plants for a long time. Fertilizer application rates are indicated on their packaging.
When growing indeterminate tomatoes, special attention should be paid to fertilizing. If low-growing varieties can often do without them without losing much in yield, then tall varieties simply will not bear fruit.
Shaping and garter
Bushes must be formed. Fruiting clusters are formed after the 9th leaf. First, the first one appears, and after a short period of time, the second one develops 3 leaves higher, and so on continues along the entire stem.
The first stepson is formed after the appearance of the first brush, just below it. It can be left to increase the yield of the plant. As soon as the first brush is formed on it, it is pinched, leaving 2 sheets above the brush. All other stepsons are removed from the bush immediately after their appearance. They should be removed by hand. They break off easily and do not leave significant damage on the stem.
Leaves from the plant begin to be plucked from mid-June. This is done according to the following scheme: as soon as the tomatoes on the bunch reach their size established by the variety, the leaves underneath it break off. This must be done by pulling the sheet to the right or left. You cannot tear them off by pressing down, as this easily damages the stem, which is dangerous for the tomato.
At the beginning of August, all bushes are plucked, removing the crown, and thereby stopping their growth. In mid-August, all the flowers are picked off. In early September, the entire ovary, which is less than 2 cm in size, is cut off so that the remaining tomatoes have time to gain sufficient weight before the cold weather.
The garter is made to a vertical trellis. Twine 4 mm thick is tied to a wire trellis near the ceiling of the greenhouse and lowered down. The lower end is tied around the stem of the plant at the base, and then it is wrapped every 2 leaves. As the lash grows, it is wrapped around the twine.
Disease and pest control
To prevent the occurrence of tomato diseases, it is important to strictly follow the rules of watering and feeding them. Indeterminate varieties are resistant to diseases and pests, and therefore usually there should be no problems when growing them. To protect against flying insects, you need to hang a fine mesh on the windows of the greenhouse. If diseases or pests appear, it is necessary, if possible, to immediately treat the crop with a treatment agent or remove the diseased bush from the greenhouse.
Regional features of choice
It is very important to select tomatoes so that they are suitable for climatic conditions. There are cold-resistant varieties intended for regions with changing climates, early ripening ones - ripening 100 days after sowing the seeds, mid- and late ripening ones.
