Growing late tomatoes is more justified on open land in warm regions. Here they are able to give almost all the fruits before the onset of frost. However, this does not mean that in areas with a cold climate, it is necessary to abandon the cultivation of this crop. There are late greenhouse tomato varieties that can produce good yields under cover.
Features of growing late tomatoes in a greenhouse
Planting late tomatoes in the greenhouse will give a positive result if a number of measures are taken to ensure the correct selection of seed material, preparation of the greenhouse soil and the cultivation of strong seedlings.
What to look for when choosing tomato seeds
Seed shops are littered with various varieties of tomatoes. When choosing a late crop, it is necessary to carefully study the description of the variety on the seed package. Tomatoes specially bred by breeders for indoor cultivation are suitable for the greenhouse. The main feature of such tomatoes is active growth and self-pollination.
Indeterminate tomatoes are best suited for greenhouse cultivation. They are distinguished by intensive stem growth and long-term fruiting, which allows you to get the maximum yield from a small area. As for self-pollination, here you need to pay attention to hybrids. These seeds are labeled "F1" on the packaging. Hybrids do not require pollination by bees or artificially. In addition, breeders have instilled in them immunity, which helps to fight many common diseases.
Another point that requires special attention is in what version the tomato seeds are sold. They can be coated, in the form of small balls, and just clean grains. The first ones have already passed all the necessary processing, and they can be sown immediately into the ground. Before sowing, clean grains will have to be soaked in Fitosporin-M solution and a growth stimulator, and only then immersed in the soil.
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 trace elements for the active development of tomato. When self-manufacturing soil, it is necessary to take equal proportions of peat, humus and black soil. After mixing all the components, it is necessary to add 1 liter of sand per 1 bucket of the mixture, 1 tbsp. 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 whole earth must be dug deep. At the planting site, the old soil is removed to a depth of 150 mm. The resulting grooves are poured with a solution of 1 tbsp. l. copper sulfate diluted with 10 liters of water. Now it remains to fill in the purchased or independently prepared soil instead of the selected soil, and you can plant seedlings.
Growing seedlings of late tomatoes
Sowing seeds of late varieties of tomatoes for seedlings begins in February.
The prepared grain is sown into boxes with 15 mm grooves. It is better to buy soil mixture for tomato seedlings in the store. After filling the boxes, the soil is poured with a solution of humate. Before the seeds germinate, the boxes are tightly covered with a transparent film and placed in a warm place with a temperature of 22about C. It is necessary to ensure that the substrate does not dry out by 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, seating them in peat cups. So the tomato seedlings will grow for 1.5–2 months before they are planted in the greenhouse. During this time, it is necessary to make 2 fertilizing with 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, with the agricultural technology of the culture we figured out a little, it's time to learn more about the existing late varieties and hybrids of tomatoes intended for growing in a greenhouse.
