Tomato formation - stepsonovanie
Finished planting tomato seedlings. Over a period of 3-5 days, plants overcome the stress state from changes in environmental conditions and begin to develop intensively. The height of the stem increases, new leaves bloom. In order for the plants to form a high quality crop, they must be provided with all the nutrients (organic and mineral, including basic and trace elements). When is it time to step-in? What it is? We will tell in the article.

What is pinching tomato?
Abundant nutrition of tomato plants causes increased branching of the side shoots. Greens thicken the planting of tomatoes, which contributes to the appearance of fungal and other diseases. To prevent this from happening, gardeners use a technique called bush formation or pinching.
Pasynkovka - removal of excess shoots at a certain age.
Reception helps to balance the ratio of green mass of plants with the amount of crop formation. Sometimes, to obtain large fruits, individual flowers or the entire flower brush are removed.
Stepsons are located in the bosom of the leaf, located on the main stem. In natural nature, the plant thus fights for survival, when grown in a stepson culture, the plant is not always needed and must be removed.
When do stepsoning take place?
Pasynkovka begin during the planting period and spend almost the entire vegetation. With plant disease, stepchildren are left in the bosom of healthy leaves in order to still get a fruit crop.
Tomatoes are divided according to the type of growth into determinant (limited in height 30-70 cm) and indeterminate, which can form plants up to 1.5-2.5 m in height. Both types of plants are subject to pinching, but the determinant form in three stems, and the indeterminate usually in one.
Formation of Determinant Bushes
In determinant bushes, after the appearance and development of stepchildren up to 5-7 cm, usually 3 stems form (one or two can be left). For this, stepsons are left in the bosom of the first two leaves (the lowest). They grow on the mother bush as independent plants - form leaves and fruits. The remaining vegetative stepsons on the central and two auxiliary shoots are constantly broken out when they reach 5-7-10 cm.
When removing, a 1-2 cm stump must be left, otherwise the next stepson will wake up and start to grow from the sleeping kidney.
Remember! Determinant bushes complete the growth with the formation of a flower brush at the end of the stem. Such a stalk will no longer grow and form fruitful brushes. In order to prolong the fruiting of the bush, it is necessary to identify the stepson each time during the stepsoning, which will replace the old stem that has finished growth and leave it for further growth, and remove the rest.
If the central stalk continues its development and fruit formation, then the grown stepson is pinched by 3-4 cm and this growth is limited by this technique, but not removed.
The determinant varieties and hybrids of tomatoes can not even be stepsoned or removed only those that greatly thicken plantings.
be careful! Vegetative stepsons from the first days of growth have rudimentary leaves and they are clearly visible on a small plant. Flower shoots do not have leaves, only a bare brush and the beginnings of flowers. Flower shoots are located nearby and it is easy for newcomers-gardeners to confuse them and break out the future crop.
Formation of indeterminate bushes
Indeterminate tomato bushes by their biological characteristics have unlimited growth of up to 2.0 meters or more. They are almost always formed into one stalk to get large fruits. For this, after transplanting seedlings or the final thinning breakthrough of seedling-free varieties and hybrids of tomatoes with the advent of stepchildren, the formation of bushes begins. In the axils of the leaves, all stepsons break out. Harvest is formed only on the central stem.
If bushes are formed in 2-3 stems, then on each additional stalk 1-2 shoots are also left, and the remaining stepsons are removed. Left shoots can be nipped over time.
Pasynkovka - a constant reception. You can not limit yourself to one-time removal of stepsons. In addition to pinching, it is necessary to constantly monitor the condition of the leaf mass of the bush. Old, yellow, brown leaves are removed. When changing the appearance of leaf blades, in addition to natural aging, they begin protective work to prevent the spread of diseases and pests.
