Polycarbonate greenhouse tomato varieties
When choosing tomatoes for greenhouses, many factors should be considered: yield, fruiting period, size, disease resistance, tall or undersized variety. In polycarbonate greenhouses, mainly tall tomatoes are grown. They need to be constantly pinched and tied. Indeterminate tomatoes grow to the very roof. Popular tall greenhouse varieties are:
- "Miracle of the Earth"
- "King of the Giants"
- "The Pink King"
- "Southern Tan"
- "Scarlet Mustang"
These varieties yield more yields and have a long fruiting period. From the early varieties for the greenhouse, it is better to choose hybrids: Verlioka F1, Poisk F1, Druzhok F1, Typhoon F1, etc.
Many gardeners choose tomatoes by size. Of the large-fruited, Cardinal, Eagle Heart, Mikado and others are very popular. Medium-sized tomatoes can be obtained from such varieties as Brilliant, Peter 1, Bulb, Kindergarten, etc. The following varieties are suitable for conservation: Sugar Plum, Cherry, Empire, etc.
Seed preparation and planting
Seed material must be selected of high quality without signs of disease. Before sowing, the seeds must be soaked for several days in a weak solution of potassium permanganate. The optimal time for planting seeds for seedlings is February-March. The soil for sowing and planting seeds must be the same. So the plant adapts better to new conditions.
The first shoots should be watered with warm water once a week. In the future, watering is carried out as needed. With the appearance of several leaves, the seedlings are transplanted. The seedlings are fed 2 weeks after transplanting. A solution of nitrophoska is used as a fertilizer. When the height of the seedlings reaches 20-30 cm, then they can be transplanted into a greenhouse. Fertile soil for growing tomatoes must be prepared in advance.

It is necessary to remove the top layer, at least 10 cm thick, and disinfect the soil. To do this, dilute a tablespoon of copper sulfate with water in a 10-liter bucket and pour over the prepared solution. The soil mixture for a tomato should consist of peat, sawdust and humus in a 2: 1: 1 ratio. A week before planting seedlings, it is imperative to treat the soil with phytosporin, trichodermine or other biological preparation.
This procedure will reduce the likelihood of developing fungal diseases. Seedlings are planted vertically in the prepared holes. The distance between the plants should be enough so that the bushes do not shade each other. When planting low-growing varieties, it is necessary to observe a checkerboard order and a distance of about 30 cm, since they form 2 shoots.
Tall plants are planted at a distance of 60-70 cm from each other. Moisten the bottom of the hole slightly, plant the plant and sprinkle with earth. In this case, it is necessary to ensure that the roots of the plant are completely closed. There is no need to water the bushes when planting. The first watering is performed after 2 weeks.
Tomato care rules
Caring for tomatoes consists in timely watering, high-quality feeding, garter, weeding and processing of plants. The plant is watered once a week before flowering. Watering should be moderate and only at the root. It is important to prevent waterlogging of the soil, as this can lead to rotting of the fruit.
Watering is desirable in the evening. A few weeks after planting the seedlings, the bushes need to be tied up. It is also necessary to carry out pinching when the plant begins to gain green mass.
This procedure is performed only in the morning. Side shoots should be removed regularly, and top dressing should be done during the growing season. Fertilizer is applied when the first ovaries are formed. You can use mullein solution, urea potassium nitrate, potassium monophosphate, etc. Foliar dressing is recommended in the evening. Dew in the morning promotes better absorption.
To increase the number of ovaries, it is recommended to spray the tomatoes with a boric acid solution. When growing tomatoes in greenhouses, the temperature regime must be observed. In the daytime, the optimum temperature is 20-28 degrees, and in the evening and at night 15-16 degrees. Pollination of tomato flowers is carried out manually, since the access of bees to flowers is difficult. During pollination, you need to gently shake the brushes of the plants, and then water and spray the bush with water.
After that, it is necessary to ventilate the greenhouse, in order to avoid waterlogging of the air and soil. Ventilate tomatoes regularly. You need to open not only the side, but also the upper vents. Airing must be done during the flowering of tomatoes. If flowers and fruits fall off a plant, this indicates an increased dryness of the air in the greenhouse. This problem can be eliminated by watering and ventilating the greenhouse.
To prevent the appearance of pests and diseases, it is necessary to carry out agrotechnical measures for the care of tomatoes in a timely manner. Tomatoes are most often exposed to root rot, late blight, black leg. To combat possible diseases, it is necessary to disinfect the soil, spray the plants with fungicidal agents.
Good lighting, the right amount of moisture and heat, timely fertilization and regular maintenance - all this contributes to the early ripening of tomatoes. If you follow all the recommendations for caring for tomatoes, you can grow a good harvest.
