Growing seedlings
The most favorable way to grow tomato variety Tretyakovsky F1 is in a greenhouse. Therefore, to obtain an earlier harvest, it is recommended to plant seedlings.
Stages of sowing grains:
- The soil mixture for seeds is prepared. When harvesting land yourself, it is advisable to first disinfect it. To do this, the soil is calcined in the oven. To obtain a fertile mixture, take equal parts of garden soil, compost and sand. The best option is a ready-made store-bought soil mixture.
- Typically, producers of hybrid tomato seeds inform buyers about seed treatment. Therefore, Tretyakov F1 grains can be planted dry. If you want to be on the safe side, you can soak the seeds in warm water and place them in a wet napkin until they germinate (the material is placed in a warm place). The material must not be allowed to dry out, so it is necessary to moisten the fabric periodically.
- On the surface of the moistened soil, grooves 0.5-1 cm deep are made, into which the sprouted seeds are placed at a distance of approximately 2 cm from each other. Seeds of the Tretyakovsky F1 variety are sprinkled with soil and lightly compacted. The box with planting material is covered with film or glass and placed in a warm place (+ 22...+25˚ C).
- After about 5-7 days, the seeds germinate. You can remove the covering material and place containers with seedlings in a bright place.
As soon as two leaves grow on the seedlings, you can plant the sprouts in separate cups.At this stage of growth, Tretyakovsky F1 seedlings are watered once a week. When more than five leaves appear on the stems, watering is carried out twice a week.
The use of lighting is an important condition for growing strong seedlings of the Tretyakovsky F1 variety. For these purposes, a phytolamp is installed near the container. The first time fertilizers are applied to the soil one and a half weeks after transplanting the seedlings. To feed the seedlings, water it once a week with a solution of vermicompost (add 2 tablespoons of fertilizer per liter of water).
10 days before planting the sprouts in the greenhouse, they begin to harden them and take them outside. The time spent in the fresh air is increased gradually.
Caring for tomatoes in a greenhouse
Tretyakovsky F1 tomato seedlings can be planted in late April-early May, which is determined by the climatic characteristics of the region. The soil temperature should not be lower than + 14˚ C, otherwise the root system of the seedlings may rot.
Greenhouse preparation:
- in film structures the coating is changed;
- disinfect the greenhouse;
- prepare the soil - dig up the soil and arrange the beds;
The indeterminate variety Tretyakovsky F1 is planted at a distance of 65-70 cm from each other. There should be no more than four tomatoes per square meter of land. To form a bush, leave two or three stems. Particular attention is paid to the garter of the Tretyakovsky F1 tomato, otherwise during the period of fruit ripening the branches may simply break off. To prevent the growth of the bush, pinching is constantly carried out.
Feeding and watering tomatoes in a greenhouse
Foliar feeding of Tretyakovsky F1 tomatoes is not practiced, since the humid environment of the greenhouse can cause the occurrence and rapid spread of infections. The solution for fertilizing the soil is prepared per 10 liters of water:
- the first time dissolve 20 g of ammonium nitrate, 50 g of double superphosphate and 10 g of potassium chloride. Fertilizer is applied one to two weeks after transplanting the sprouts;
- as soon as ovaries form on the bushes, add a solution of 80 g of double superphosphate and 30 g of potassium nitrate;
- the third time during the ripening period, a solution of 40 g of double superphosphate and 40 g of potassium nitrate is added.
Watering rules
Young seedlings are watered sparingly as the soil dries. During the ripening period of Tretyakovsky F1 tomatoes, there should not be a lack of moisture, so watering is required infrequently, but plentifully. It is advisable to carry out the procedure during the day, then the water will be warm enough and you can have time to ventilate the greenhouse well before the evening temperature drops.
The optimal option for watering tomatoes of the Tretyakovsky F1 variety is equipment of a drip system. At the same time, the structure of the top layer of soil is preserved, there is no sharp change in soil moisture, and a minimum of effort is expended on the process.
Diseases and pests
The Tretyakovsky F1 variety has high immunity, so it practically does not suffer from fungal diseases. However, it is worth paying attention to the prevention of late blight and pest control.
Late blight is a fungal disease that affects the leaves of individual bushes and spreads quickly.Greens and fruits become covered with brown and brown spots. If you do not carefully treat each bush, then all the plants can die in just a few days. A favorable environment for the spread of the disease is humidity and low temperature. The main measure to combat fungus is prevention. As soon as cold, rainy weather sets in, the tomatoes are sprayed with special preparations (Fitosporin, Ecosil, Bordeaux mixture). If the first affected leaves are discovered, they must be plucked and burned. Tomatoes should be picked green, washed and disinfected thoroughly (it is enough to keep them in water for 2-3 minutes at a temperature of +55...+60˚ C).
The cutworm is a small butterfly whose caterpillars can harm the Tretyakovsky F1 tomato. Pests destroy not only foliage, but also green or ripe fruits. The insect overwinters well at a depth of about 25 cm. To combat the pest, pollinate tomato bushes and carefully remove weed, digging up soil in late autumn.
