Sometimes the modest size of the plot does not allow the summer resident to “go wild” and plant all the varieties of vegetables he likes. The optimal solution is to plant indeterminate varieties of tomatoes, thanks to which you can significantly save space and grow more different crops.
Description of the variety
Tomato Kirzhach F1 is a first generation hybrid, the result of the work of breeders. This is an indeterminate variety characterized by an average ripening period (105-115 days). Tomatoes are grown in greenhouses. The tomato variety Kirzhach F1 fully meets the characteristics of indeterminate varieties: a tall plant, very leafy.
The stems are strong and not susceptible to breaking. The leaves are large and not very dissected. When growing tomatoes in a greenhouse, you usually pinch off the tops. The manufacturer recommends forming the tomato into one stem. The first inflorescence appears above leaves 9-11.
Tomatoes of the Kirzhach F1 variety ripen in large sizes and have a round shape. The peel is red, smooth and with a glossy sheen (as in the photo). The tomato is distinguished by its fleshy pulp and pleasant taste. Excellent for fresh consumption. The Kirzhach F1 variety is distinguished by its stable yield. On average, up to 6 kg of fruit can be collected from one bush.
Advantages of the indeterminate variety Kirzhach F1:
- long growing season.On the Kirzhach F1 tomato, new fruits are constantly formed, right up to the first autumn frosts;
- the tomato is resistant to blossom end rot, fusarium, and tobacco mosaic virus;
- there is a constant flow of air to the tied stems. Thanks to natural ventilation, Kirzhach tomatoes are practically free from late blight and rot;
- high yields in compact areas. Tomatoes are perfectly preserved and transported.
When growing Kirzhach, some disadvantages should be noted:
- the need to arrange trellises, which is associated with both material and physical costs;
- You cannot collect seeds of the Kirzhach F1 variety for growing tomatoes in the future. Which, in principle, is typical for all hybrids;
- A tomato of this variety needs constant care in terms of forming a bush, removing stepsons and excess foliage, and tying up stems. If you do not remove shoots, the greenhouse will turn into a continuous green thicket.
Rules of care
To grow tomatoes of the Kirzhach F1 variety, the seedling method is used. Depending on the climatic characteristics of the region, seeds are planted in late February-early March.
Seeds of the Kirzhach variety from trusted producers usually do not require pre-treatment (information is indicated on the packages).
Germination stages
- Loose and nutritious soil is prepared in the boxes (with the addition of sand and peat). You can also add wood ash or superphosphate to the soil.
- Tomato seeds of the Kirzhach F1 variety are laid out on a moistened soil surface in even rows and sprinkled with a thin layer of earth (approximately 4-6 mm). The soil surface is sprayed with water.To prevent the soil from drying out, the box is covered with plastic film or glass.
- It is recommended to place the container in a warm place (approximately 20-23˚ C). As soon as the first tomato sprouts appear, the film is removed and the boxes are placed in a lighted place. Containers should be placed in a warm, well-lit place, without drafts.
- When the second pair of leaves appears on the tomato sprouts of the Kirzhach variety, it is necessary to fertilize. As a fertilizer, you can use a solution of a mixture of phosphorus, nitrogen, and potassium, taken in equal parts. After a few days, you can plant Kirzhach tomato seedlings in separate pots. The sprouts must be picked up carefully so as not to damage the tomatoes.
On the eve of planting Kirzhach seedlings in the greenhouse, it is necessary to harden the seedlings. To do this, two weeks earlier the tomatoes are taken out into the open air. Of course, you shouldn't get carried away. Only on warm sunny days can the Kirzhach F1 tomato variety stand outside for several hours. This procedure is especially important when planting seedlings in an unheated greenhouse.
It is advisable to start planting tomato seedlings in early May. To create favorable conditions in the greenhouse, it is advisable to annually update the top layer of soil. To do this, clean river sand and humus are poured into the garden soil.
The holes are dug at a distance of 35-45 cm from each other. Wood ash or a tablespoon of superphosphate is added to each hole.
After transplantation, each seedling of the tomato variety Kirzhach F1 is tied to a support (stakes, rods or trellis). Since the tomato grows very quickly, high supports are immediately installed. Form a tomato into one stem, carefully removing unnecessary shoots. After three weeks, you can fertilize the tomatoes.Solutions of mineral mixtures (mainly phosphorus and potassium) are used as fertilizers. During this period, it is recommended to abandon the use of nitrogen fertilizing, as it promotes abundant growth of tomato greens, which prevents the formation of ovaries.
Watering tomatoes
The Kirzhach variety does not welcome abundant watering. For these tomatoes, it is preferable to choose moderate soil moisture twice a week. But this regime depends on climatic conditions. In dry, hot summers, Kirzhach tomatoes need to be watered more often. It is recommended to pour water at the root.
It is imperative to regularly loosen the soil to remove the crust that impedes air exchange.
To provoke the appearance of new ovaries, you can pick Kirzhach tomatoes unripe. It is advisable to monitor the formation of deformed ovaries and immediately tear them off.
Tomato pests and diseases
Kirzhach is characterized by increased resistance to many diseases. However, in greenhouse conditions there is a possibility of the appearance of some diseases.
Late blight (fungal disease) is one of the most common diseases of tomatoes. High humidity in the greenhouse and cool temperature can provoke the appearance of fungus. Disease affects tomatoes, leaves, stems. Symptoms appear as brown spots.
The complexity of the situation lies in the fact that it is no longer possible to completely cure the plant. Alternatively, you can contain or slow down the development of the disease in time to harvest the tomatoes.Therefore, the main way to fight is prevention, which will prevent the onset of the disease or slow down its development:
- the soil in the greenhouse before planting seedlings is treated with a biological solution (Gamair, Alirin) in the proportion: tablet per 10 liters of water;
- after planting the seedlings, Kirzhach F1 tomatoes are sprayed with solutions of biological preparations (Gamair, Alirin) at the rate of one tablet per liter of water;
- Sudden changes in air temperature (decrease) and humidity (increase) should not be allowed in the greenhouse. If signs of disease appear, you should immediately reduce the number of waterings.
Of the greenhouse pests of Kirzhach tomatoes, slugs are especially worth highlighting, as they can significantly reduce the tomato yield. You can get rid of pests in various ways: chemical, agrotechnical and mechanical.
Agrotechnical ones involve loosening and digging the soil, weeding weed and timely thinning of tomatoes.
Mechanical ones involve the use of traps (sheets of cardboard, pieces of burlap, boards). The devices are installed in the evening, and in the morning the pests are collected and destroyed. However, this method is considered ineffective, since after a short period of time the slugs appear again.
Chemical agents are considered more effective. Saturated salt solutions, a 10% solution of copper sulfate, a mixture of stove ash, mustard, and red pepper are used. Processing must be carried out repeatedly.
Thanks to its high yield and unpretentiousness, the Kirzhach F1 tomato is becoming increasingly popular among gardeners. And disease resistance allows it to be grown in different regions.
