Rules for growing tomatoes in greenhouses

After transferring the seedlings to the greenhouse, it is necessary to regularly water the seedlings. It is important to remember that the plant does not tolerate wet soil.
Until the tomatoes bloom, you will need about 4 liters of water per square meter. Subsequently, the volume increases to 12 liters. It is also recommended to adhere to the temperature regime. The optimum water temperature for irrigation is 22-24 degrees.
Water the tomatoes every 6-7 days. At very high humidity, the pollination process may not take place. Airing is an important part of tomato care. Always open the vents during the day. Daytime temperatures should be within 22 degrees, and night temperatures should be at least 20 degrees. During flowering, the temperature can be raised to 25 degrees.

Ripe tomatoes can be sprinkled with a special stimulant preparation that promotes the appearance of new ovaries. It should be sprayed at the time of the appearance of the peduncle and after the rapid flowering.
Pollination of tomatoes should be not only natural, but also mechanical. To do this, you need to knock on the stems so that the pollen hits the pistil. When growing tomatoes in greenhouse conditions, it is important to create favorable conditions, only in this case you can get a good harvest.
