Most vegetable growers prefer to grow tomatoes in their gardens or greenhouses. These vegetables are anti-cancer and contain various beneficial microelements and vitamins. There are many different types of tomatoes. However, many gardeners grow semi-determinate tomatoes.
Description
To understand what semi-determinate tomato varieties are, you need to know the distinctive features and characteristics.
It is quite easy to distinguish different types of tomatoes.The difference between semi-determinate, indeterminate and determinate varieties is the height of the plant. Semi-determinate 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 among 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 such plants has some features that you should familiarize yourself with before planting.
Seedling
To get good seedlings, you need to know how to grow them correctly. 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. Seedlings need to be transplanted 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 harvest. 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 night temperature should not be 15 degrees. Temperatures that are too high or low can negatively affect the development of bushes. Sometimes they stop growing and new fruits stop forming on them.
Watering
Tomatoes are plants that need regular watering. Newly planted seedlings need to be watered frequently. However, you should not overwater them, as this may 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 to a depth of 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 fungal diseases.
Bushes should be watered only at the root, since water should not get on the stems and leaves of the plant. This method of watering is also used so as not to increase the level of humidity 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 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. 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 do not have enough phosphorus. The most dangerous is a lack of potassium, as this can cause tomatoes to die.
Stepsoning
First, you need to understand what stepsons are. Side shoots are called side shoots, and it is recommended to get rid of them. This is done to accelerate the ripening of fruits and to increase their weight.If the extra shoots are not removed in a timely manner, a large number of leaves will form on the bushes and this will lead to the tomatoes being too small.
It is recommended to remove stepchildren after they grow to five centimeters in length. This procedure should be carried out early in the morning once a week.
Bush formation
Semi-determinate tomato varieties are recommended to be formed 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 a second one.
In the future, we will have to start shaping the harvest. To do this, you will have to remove excess fruit from the first two clusters 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.
