Growing and care
Seeds for seedlings should be planted in late March - early April in seedling containers to a depth of about 1.5-2 cm. If they are not granulated, then it is advisable to first soak them in a pink solution of potassium permanganate.
At temperatures from +23 to +25 C, seedlings will appear on the surface within 4-8 days. Next, the temperature should be lowered to +17...+20 C. When watering seedlings, try to prevent moisture from getting on the delicate leaves. In the phase of 2 true leaves, plant (pick) the plants in individual containers.
At the age of 50-55 days, bushes with 5-6 leaves are ready for planting in a permanent place. Planting pattern - 50x40 cm (4 bushes per 1 m2). If you plant in the exhaust zone, then step back 25-30 cm between plants in a row, and place adjacent beds at a distance of 50-90 cm from each other. Bushes should be formed into 1-2 stems.
In care, special attention should be paid to regular watering at the root at intervals of 1-2 times a week (with warm, settled water, in the morning or evening), weeding, loosening (once every 10 days). As the bushes grow, point garters should be made to individual support pegs.
Timely fertilizing improves the overall yield quite well. The first time comes 12-14 days after transplantation. You can use diluted mullein or chicken manure. A urea solution is also suitable instead.
During fruit set, the application of potassium-phosphorus mineral fertilizers, including wood ash, can be of great benefit.

The prefix “F” in the name of the variety means one thing - it is a hybrid. A unit indicates that the seeds in the package belong to the first generation. What does this mean?

Formation of a tomato bush Irina
Why are tomatoes planted? In their homeland - Mexico - tomatoes bear fruit well without any interference in the structure of the bush. However, in our climatic conditions, where there is not much light and heat, it is difficult for the plant to cope with the formation and ripening of a large number of fruits. In view of this, a practical solution would be to artificially reduce the potential yield of the bush.
In the photo there is an Irina tomato, formed into one trunk With abundant foliage of the bush, the roots are not able to provide adequate nutrition to the entire plant. The dry matter that goes into the formation of three tomato leaves is enough to form one full-fledged fruit. In addition, dense tops shade the plant, slowing down the process of fruit ripening and promoting the development of diseases.
How does pinching of tomatoes occur? Stepchildren are shoots of the main stem that form in the axils of the leaves. When forming a tomato Irina into two stems, you should leave the main trunk and the most developed stepson. All the rest are gradually removed, performing the procedure every week. The easiest ones to break off are the stepsons on which the leaves have not yet had time to fully develop.
Reminders for growing tomatoes
In conclusion, we would like to remind you of the main features of caring for tomatoes, which, if neglected, can cause serious problems:
Tomatoes should only be watered at the roots, using water heated in the sun.
During the rainy season, loosen the soil so that the moisture evaporates faster.
