Semi-determinate tomato variety: what does it mean, types for greenhouses and greenhouses

Most vegetable growers prefer to grow tomatoes in their gardens or greenhouses. These vegetables are anti-cancer, contain various beneficial trace elements and vitamins. There are many different types of tomatoes. However, many growers grow semi-determinate tomatoes.

Description

To understand what semi-determinant varieties of tomatoes are, you need to know the distinctive features and characteristics.

Distinguishing different types of tomatoes is quite simple. The difference between semi-determinate, indeterminate and determinate varieties is the height of the plant.Semi-determinate bushes are of medium height, they have adopted the best qualities from the other two types of tomatoes. That is why they are so popular with vegetable growers.

The first fruits of semi-determinate tomatoes can be harvested two months after planting in the ground. Such plants are resistant to diseases and cope with temperature changes without problems. However, they cannot cope with too low temperatures and sometimes they have to be grown in greenhouses.

In greenhouse conditions, most bushes grow up to two meters. During growth, about 10-15 inflorescences are formed on them, the first of which appears above the tenth leaf.

Features of cultivation

Growing these plants has some peculiarities that you should be familiar with before planting.

Seedlings

To get good seedlings, you need to know how to grow them correctly. Seedlings are not recommended to bring to flowering. If this happens, then you need to immediately get rid of the inflorescence. It must be grown in well-lit rooms with a stable temperature of about 20 degrees Celsius. It is necessary to transplant seedlings into the ground only after 5-7 leaves appear on them.

Temperature

It is recommended to regularly monitor the temperature in the greenhouse, as it affects the amount of the crop. During planting seedlings, the temperature should be about 15 degrees Celsius. The daytime temperature in the greenhouse should not be below 25 degrees, and at night - 15 degrees. Too high or low temperatures can adversely affect the development of bushes. Sometimes they stop growing and new fruits stop forming on them.

Irrigation

Tomatoes are plants that need regular watering. Newly planted seedlings need to be watered frequently. However, do not flood them too much, as this may adversely affect growth. It is recommended to moisten the soil only after its top layer is completely dry.

Adult seedlings are recommended to be watered twice a week. At the same time, the soil should be saturated with moisture by 20 cm. During the formation and ripening of fruits, the frequency of irrigation increases several times. It must be remembered that a large amount of moisture can lead to the appearance of fungal diseases.

Shrubs should be watered only under the root, as water should not fall on the stems and leaves of the plant. Also, this method of watering is used in order not to increase the level of humidity in the greenhouse.

Feeding

In order for semi-determinant tomatoes to give an early harvest, it is necessary to feed them in a timely manner. Such plants need mineral supplements with a large amount of phosphorus. They should also contain a lot of potassium, which will be needed to speed up the ripening of tomatoes.

You can understand what elements a plant lacks by its appearance. With a lack of nitrogen, the bushes will grow slowly and their leaves will be too pale. If the leaves turn purple, then most likely the bushes do not have enough phosphorus. The most dangerous is the lack of potassium, as this can kill tomatoes.

Staging

First you need to figure out what stepchildren are. Side shoots are called stepchildren, from which it is recommended to get rid of. This is done to accelerate the ripening of fruits and to increase their mass.If you do not remove the extra stepchildren in a timely manner, then a large number of leaves will form on the bushes and this will lead to the fact that the tomatoes will be too small.

It is recommended to remove stepchildren after they grow up to five centimeters in length. This procedure should be carried out early in the morning once a week.

Shaping a bush

Semi-determinant varieties of tomatoes are recommended to be formed in two stems. Thus, the most viable stem will form near the first brush. It is he who will give the best and greatest fruits. From the formed first stem, it is necessary to form the second one.

In the future, we will have to deal with the formation of the crop. To do this, you will have to remove excess fruits from the first two brushes and leave only 2-4 tomatoes there. All other brushes must be formed in such a way that no more than 5-6 fruits remain on them.
