Caring for tomatoes in a greenhouse: watering-pollinating

To harvest a rich harvest of tomatoes, you need not be lazy to properly care for vegetables. In a greenhouse, plants are more sensitive to maintenance than outdoors.


  • Care
  • Top dressing
  • Priming


After planting, caring for tomatoes in a greenhouse consists of three mandatory components:

  • watering;
  • pollination;
  • airing.

Watering the tomatoes begins 12 days after planting. Tomatoes do not like too moist soil. Therefore, the watering norms should be strictly observed: 4 liters per 1 m2 - before flowering, 12 liters per 1 m2 - during flowering and fruit formation.

Water the tomatoes every 5-6 days. It is important to ensure that the water temperature is at least + 22 ° C. It is necessary to ensure that the humidity in the greenhouse is not increased, because this prevents pollination of flowers. In addition to natural pollination, tomato flowers also need to be pollinated mechanically.

To do this, shake the inflorescences daily. It is better to do it during the day in sunny weather. After shaking the flowers, the plants are sprayed, and the greenhouse room is ventilated.

True, spraying and accumulation of condensate in the greenhouse can lead to the development of fungal diseases. Therefore, it is better to combine spraying with foliar dressings and add Fitosporin or Gamair in turn there.

Airing is very important in greenhouse tomato care. To regulate the humidity in the room, vents should be provided. For tomatoes, the comfort temperature is + 19 ° C - + 22 ° C during the day and + 16 ° C - + 20 ° C at night. During flowering and fruiting, the temperature should be 1-2 degrees higher (but not higher than + 27 ° C).

Top dressing

Also, do not forget about feeding. You need to start feeding the plants from the moment the first ovary is formed. Depending on the growth phase, liquid mullein, potassium sulfate, superphosphate and wood ash can be used.

Liquid dressings from herbal teas are good.

For a week or two, plant residues are tightly packed into the container (weeded weeds can be added) with the addition of nettle, and filled with warm water. The container is closed with a lid. Mullein and preparations with microorganisms can be added to it. If you are going to fertilize at the root, then the resulting infusion is diluted 1 part to 20-30, for foliar dressing it is bred more, about 40-50 times.


As a rule, many pathogens and pests accumulate in greenhouses over time. But if you think over and make the correct laying of the soil, and then take care of it systematically, you can avoid the exhausting frequency of replacing the soil.

The first bookmark (or replacement) is done like this. The soil is taken out of the greenhouse on a bayonet, spilled with water. Then the surface is covered with a transparent film and left for a month or two under the so-called steam. By the fall, you can sow any siderates. They actively sprout even in October, gaining green mass very quickly. Good results are obtained by sowing crucifers with legumes, they help from root rot.

In early spring, a mixture of compost, garden soil and sand is applied (directly to the green manure). The soil is carefully compacted and spilled. Already in March, any spring green manure can be sown again, except for rye. The rye is too allelopathic, its root and leaf secretions can overwhelm the tender tomato seedlings.

By the time the seedlings are planted, the beds are marked, their borders are fixed with the help of borders.

Various materials are suitable - bricks, boards, slate. It would be nice to lay boards or tiles along the paths - the earth does not like to be trampled. The grown siderates are not pulled out, they are simply cut off at the root and folded in the beds.

After planting the seedlings, the entire free area of ​​the earth is covered with a large layer of compost. Then, throughout the season, add a mulch layer of straw and cut grass. A large layer of mulch prevents late blight from spreading, even if its spores have entered or remained in the greenhouse. The lower leaves are cut off, do not allow contact with the ground.

The presence of earthworms also affects the health of the soil. Therefore, you can collect them at the bottom of the compost heap and transfer them along with the substrate. It is good to sow legumes in the aisle, they enrich the soil with nitrogen, and the root system of tomatoes will completely entwine their roots by the end of the season. Basil is sown along the curbs. It gets along well with tomatoes, makes the taste of the fruit richer.

So, growing tomatoes in greenhouses is a very exciting household. By learning how to ventilate the greenhouse in a timely manner, ensuring systematic watering and helping the plants with pollination a little, you will achieve a good harvest. And in order not to change the soil often, start to heal the soil with the help of regular application of organic matter, then the care of the greenhouse will become very easy over time. Of course, it will not be possible to get one hundred percent recovery in a year. But within three years, you will feel a real improvement in the microflora in your greenhouse.
