Growing late tomatoes is more justified on open land in warm regions. Here they are able to produce almost all the fruits before the onset of frost. However, this does not mean that in areas with cold climates one should abandon the cultivation of this crop. Exist late varieties of tomatoes for greenhouses, capable of producing good harvests under cover.
Features of growing late tomatoes in a greenhouse
Planting late tomatoes in a greenhouse will give a positive result if you follow a number of measures aimed at choosing the right seed material, preparing greenhouse soil and growing strong seedlings.
What to look for when choosing tomato seeds
The counters of seed stores are filled with various varieties of tomatoes. When choosing a late crop, you must carefully study the description of the variety on the seed packaging. Tomatoes specially bred by breeders for growing indoors are suitable for the greenhouse. The main feature of such tomatoes is active growth and self-pollination.
For greenhouse Indeterminate tomatoes are best suited for growing. They are characterized by intensive stem growth and long fruiting, which allows you to get maximum yield from a small area. As for self-pollination, here you need to pay attention to hybrids. Such seeds are marked “F1” on the package. Hybrids do not require pollination by bees or artificially. In addition, breeders instilled in them immunity, which helps fight many common diseases.
Another point that requires special attention is what type of tomato seeds are sold in. They can be panned, in the form of small balls, or just pure grains. The first ones have already undergone all the necessary processing, and they can be immediately sown in the ground. Before sowing, clean grains will have to be soaked in a solution of Fitosporin-M and a growth stimulant, and only then immersed in the ground.
How to prepare the soil in a greenhouse
A high survival rate of tomato seedlings and a bountiful harvest are possible with well-prepared soil. The easiest way is to buy ready-made soil in the store. It contains all the necessary microelements for the active development of tomato. When making your own soil, you need to take equal proportions of peat, humus and black soil. Having mixed all the ingredients, you need to add 1 liter of sand, 1 tbsp per 1 bucket of the mixture. wood ash and 1 tbsp. l superphosphate.
The soil in the greenhouse begins to be refined 2 weeks before planting the seedlings. Tomato roots love an abundant supply of oxygen, so the entire soil must be dug deep. In the place where plants are planted, old soil is removed to a depth of 150 mm. The resulting grooves are filled with a solution of 1 tbsp. l. copper sulfate diluted with 10 liters of water.Now all that remains is to fill in purchased or self-prepared soil instead of the selected soil, and you can plant the seedlings.
Growing late tomato seedlings
Sowing seeds of late varieties of tomatoes for seedlings begins in February.
The prepared grains are sown in boxes with 15 mm grooves. It is better to purchase soil mixture for tomato seedlings in the store. After filling the boxes, the soil is filled with a humate solution. Before the seeds germinate, the boxes are tightly covered with transparent film and placed in a warm place with a temperature of 22O C. It is necessary to ensure that the substrate does not dry out, periodically moistening it with water from a spray bottle.
After the sprouts appear, the film is removed from the boxes and uniform light is directed so that the seedlings do not stretch. With the appearance of 2 full-fledged leaves, the plants dive into peat cups. This way, tomato seedlings will grow for 1.5–2 months before being planted in a greenhouse. During this time, it is necessary to apply 2 fertilizers. 2 weeks before planting, the seedlings are hardened by daily removal to a cool place. At the time of planting, the height of the plants should be within 35 cm.

Review of late greenhouse tomatoes
So, now that we have a little understanding of the agricultural technology of the crop, it is time to learn in more detail about the existing late varieties and hybrids of tomatoes intended for cultivation in a greenhouse.
Russian size F1
The hybrid is characterized by a powerful bush structure up to 1.8 m high. The indeterminate plant produces abundant tomato yields in heated greenhouses and under cold film cover. The hybrid is not grown in the garden. Fruit ripening occurs after 130 days. Tomatoes grow large, weighing 650 g. There are giants weighing up to 2 kg.The slightly flattened fruit shows faint ribbing. Inside the juicy pulp there are 4 seed chambers. Tomatoes are tied on the stem in tassels of 3 pieces each. The large size of the vegetable does not allow it to be canned. This late tomato is used for processing and salads.
The first garter of the stem is carried out immediately a week after planting the plant in greenhouse soil. The bush is not very branchy, but is densely covered with foliage. When pinching, only 1 central stem is left, and all other shoots and lower leaves up to the first inflorescence are removed. Towards the end of fruiting, the top of the plant is broken off to stop its growth. One plant can bear up to 4.5 kg of tomatoes.
Miracle of the market
By the end of 4 months, you can be sure that the tomato is fully ripe. The culture is intended only for greenhouse cultivation. The bush grows up to 1.6 m high. The stem cannot support the weight of the fruit on its own and must be tied to a trellis or any support. The vegetable grows large, usually weighing 300 g, but there are large tomatoes weighing 800 g. Fleshy tomatoes have a decent presentation. The vegetable is not used for canning; it is mostly used for processing and cooking.
King of Kings F1
A new complex hybrid has been bred for farms and home gardens. Seed material cannot be obtained from it at home. The hybrid is a representative of giant greenhouse tomatoes, but in the southern regions open cultivation is allowed. The indeterminate plant grows up to 2 m in height.The bush is moderately covered with foliage. During pinching, the plant is left with 1 or 2 stems, tying them to the trellis as they grow. In an adult plant, the first cluster of tomatoes appears above the 9th leaf, and all subsequent ones are formed after 3 leaves. The vegetable is considered fully mature after 4 months. The plant is slightly affected by late blight and is considered productive. You can take up to 5 kg of tomatoes from one bush. Experienced vegetable growers have determined that the highest yield of the hybrid is observed when grown under film. In glass greenhouses and polycarbonate, the yield is slightly lower.
Large round tomatoes with a flattened top weigh from 1 to 1.5 kg. A tomato weighing less than 200 g is not found on the plant. Inside the fleshy red pulp there are up to 8 seed chambers. The fruits are set in clusters of 5 tomatoes each. The giant-sized vegetable is used only for processing or salads.
Citrus garden
This indeterminate tomato gives good results when grown in film greenhouses. Tomato ripeness is observed after 120 days. The bush is very spreading; when forming, up to 5 branches are left on the plant. The yellow fruits resemble lemons. The weight of one tomato is about 80 g; they are formed on the plant in clusters.
