What does semi-determinant tomatoes mean, varieties 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 gardeners grow semi-determinate tomatoes.
Description
To understand what semi-determinant tomato varieties are, you need to find out the distinctive features and characteristics.
It is quite simple to distinguish between different types of tomatoes. The difference between semi-determinant, indeterminate and determinant varieties is the height of the plant. Semi-determinant bushes have an average 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-determinant 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.
Growing features
The cultivation of such plants has some features that should be familiarized with before planting.
Seedling
To get good seedlings, you need to know how to grow them properly. It is not recommended to bring seedlings 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, since it is this temperature that affects the amount of the crop. When planting seedlings, the temperature should be about 15 degrees Celsius. The daytime temperature in the greenhouse should not be lower than 25 degrees, and the nighttime - 15 degrees. Too high or low temperature values can negatively affect the development of the bushes. Sometimes they stop growing and new fruits stop forming on them.
Watering
Tomatoes are among the plants that need regular watering. Newly planted seedlings need to be watered frequently. However, do not flood them too much, as this can negatively affect growth. It is recommended to moisten the soil only after its top layer is completely dry.
It is recommended to water adult seedlings twice a week. In this case, the soil should be saturated with moisture by 20 cm. During the formation and ripening of fruits, the frequency of watering increases several times. It should be remembered that a large amount of moisture can lead to the appearance of fungal diseases.
Bushes should be watered only at the root, as water should not get on the stems and leaves of the plant. Also, this method of irrigation is used so as not to increase the humidity level in the greenhouse.
Top dressing
To semi-determinant tomatoes gave an early harvest, it is necessary to feed them in a timely manner. Such plants need mineral fertilizing with a large amount of phosphorus. They should also contain a lot of potassium, which is needed to accelerate the ripening of tomatoes.
You can understand what elements a plant lacks by its appearance. If there is 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 lack phosphorus. The most dangerous is the lack of potassium, as this can kill the tomatoes.
Stealing
First you need to figure out what stepsons are. Lateral 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 stepsons 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.
Bush formation
It is recommended to form semi-determinant tomato varieties into 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.
In the future, you 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.
