Growing tomatoes in a greenhouse

To correctly know how to grow tomatoes in a greenhouse, you need to follow the simple, but mandatory stages of care, starting from seed treatment and ending with the formation of fruits.

Tomato seed treatment before sowing

Caring for tomatoes in a greenhouse dates back to the seed treatment period, so that the crop resists viral diseases. To do this, use potassium permanganate treatment, which is performed before germination and includes the following steps:

• preparation of a special solution – 1 g of the product is taken in a glass of water;
• a gauze bag is taken, seeds are laid there, lowered into the solution;
• after 20 minutes, the seeds are washed with clean running water.

This treatment helps the rapid simultaneous emergence of seeds, strong growth of bushes. After processing with potassium permanganate, it is useful to saturate the seeds with useful substances, which is carried out according to the following technology:

• prepare a solution of 1 liter of warm water with 1 tablespoon of fertilizer (ash, nitrofoska, sodium humate);
• a container is taken, a bag with seeds is laid there for 12 hours at a temperature of at least 25 degrees;
• after taking out the dishes with clean water, the bag is put in there for a day.

Such care is useful for undersized varieties, along with hardening, when the bag is placed on the shelf of the refrigerator for 2 days at a temperature of at least 1 degree. During the time spent, the seeds must be constantly sprayed with water so that the bag does not dry out, and immediately after hardening it is planted. Soaking and hardening is not necessary for hybrid seeds and varieties with high stems.

Compliance with the temperature regime

It is carried out 10 days after germination, so as not to damage the small root. A competent transplant involves watering in 2 hours, taking out seedlings and selecting a large pot, watering again. The second method of picking is transshipment, when a few days before transplanting, the bush is no longer watered, due to which the earth dries and freely gets out of the pot. After transshipment, the plant needs to be watered to the best of its ability, so that it is better taken root.
