How to form tomatoes in two stems in a greenhouse

Experienced gardeners know that it will take a lot of effort to remove a good harvest of large tomatoes from greenhouse beds. In addition to the timely watering and application of fertilizing, the plant needs to be helped to form correctly so that it does not waste power on the shoots. How to form tomatoes in two stems and will be discussed in this article.

Why is it necessary to form a tomato in a polycarbonate greenhouse

During the growing season from the main stem of a tomato can break off a lot of shoots, which will also be fruit. It seems that the process itself should please the gardeners with a large number of ovaries, but in reality it looks quite different.

A mature shrub with bulky greens and a small number of ovaries is not capable of providing vitamins and minerals in the required amount of fruit., as a result of which some of them fall off, others are deprived of the opportunity to ripen completely.

Forming bushes is required for almost all varieties of tomatoes. The only exceptions are standard cultures (a type of plant of the determinant type).

But how many stalks to leave on the bush? Depending on the selected hybrid / variety and haulm development features, gardeners form a bush in three ways:

  • in 1 stalk;
  • in 2 stalks;
  • in 3 stalks.
The formation of bushes in the 1-2-3 stem

In the polycarbonate greenhouse pasynkovanie aimed at obtaining high-quality yield, which is ensured by redirecting power to the main stem and fruit. Pysynki rob a plant of most of the micro and macro elements useful for development, therefore it is advisable to remove them. It is important during the procedure not to confuse the stepson with the fruit-bearing branch. Determine the excess escape can be at the place of its growth. This is the bosom of the leaf.

The advantage of pinching is to reduce the ripening time of the fruit, that is, you can pick up tomatoes 1-2 weeks earlier. Besides productivity increases due to increase in the period of fructification. Yet the main merit of the procedure is to obtain high-quality tomatoes.

How to shape the bushes in two stalks

Before you begin to remove extra shoots, you need to decide on the following questions:

  • the frequency of the procedure (in the greenhouses pasynkovat tomatoes should be 1 time in 7-10 days);
  • technique of staving plants with a method of two.

It is also worth considering that with a break in the sprout a tomato juice can get on your hands. Moving from bush to bush, there is a high probability of infecting other tomatoes with various diseases, if there is at least one affected tomato. Therefore, experts recommend wearing rubber gloves before the procedure and wipe them with an alcohol solution after each whip.

The scheme of removal of excess shoots on tomatoes

The essence of the technique of the formation of the bush is in the selection of the main stem and the first stepchild, as it is the strongest, capable of intensive development and fruiting. To determine it simply, it is located under the first brush of the inflorescences. The remaining stepchildren, who have reached a length of 4-7 cm, are boldly removed. Cut off shoots need sharply, holding them with your index and thumb. In order not to damage the main stem, move the sprout to the side when jerking, not to the side. Also cutting with the tool having a sharp edge (knife) is allowed.

When growing tomatoes in a greenhouse, bushes are formed into one or two stems. With a large number of branches, the plants are shaded and interfere with air circulation, therefore the 3-branch technique is not suitable.

How to form deterministic brushes

This group includes stunted plants of early and middle ripening periods. In principle, they do not need the formation of a bush (on average, the height of the tops reaches 55-65 cm). But experienced gardeners still carry out the procedure for obtaining an earlier harvest and increase in fruiting.

Bush, which must be removed

In determinant tomatoes, after the formation of 3-4 leaves, the first flower brush is laid on the main stem. After 2-3 leaves a second one appears, and all subsequent brushes are tied through a leaf. The last closing growth of tomato inflorescences are arranged in a row without an interval on the leaves. In the southern countries, the culture is grown without removing the stepsons, aided by the climate and the long daylight hours. In our regions it is simply necessary to participate in the process of staving.

For the formation of tomatoes of the determinant type, in addition to the main stem, the first or second stepsons are chosen. After the beginning of flowering, you need to install a support so that the branches do not break under the weight of the fruit. In a greenhouse, plants are tied up to a trellis.

Removing excess bush

Formation of indeterminate varieties

This type includes cultures that do not have growth restrictions. Most often, these varieties form in one stem, less often with two. The use of these methods is explained by the ability of indeterminate tomatoes to form a large number of side shoots.

On a plant whose height exceeds 50-70 cm, in addition to the main stem, the first or second stepson is left (a stronger and more developed version is chosen). On each branch leave 4-5 brushes of inflorescences. Sprouts located on the sides and in the root zone are removed.

Favorable time for trimming the bush are the morning hours (the weather should be dry and sunny). During this period, the plant is filled with juice as much as possible, which facilitates the process of breaking. The wound will dry out during the day, which reduces the risk of infection with fungal disease.

What will happen if growing tomatoes let go

Removal of useless sprouts contributes to the ripening of large fruits, because a tomato does not waste energy and energy. If young seedlings are not subjected to such a procedure, then the bush turns out to be highly branched, and the fruits on it will be small. Many ovaries can fall due to lack of vitamins and minerals. In addition, the beds thicken and there is a problem with airing. With increased humidity, various fungi are activated, which causes plant diseases.

Spontaneously forming tomatoes in height can reach 1 m or more, which creates problems with illumination in a polycarbonate greenhouse. And for normal growing season, light is simply necessary; it promotes protein synthesis. Therefore, the adjustment of the growth of the bush is another advantage of staking.

Scruffy tomatoes produce a lot of greens and little fruit.

The beds without the formation of bushes look unclean, it is extremely inconvenient to process them, you have to make your way through the thickets. By the end of the season, the plant remains a lot of undiminished fruit, which is unsuitable even for preservation because of its too dense structure and bitterness in the taste.

Removing stepsons does not take much time, and knowledge to perform cutting or pinching will require a minimum. But the harvest will delight large tomatoes, which will correspond to the product and taste characteristics. The scheme of how to form bushes can be applied in the open field.
