The determinant variety of tomatoes, what is it - what are its advantages and disadvantages?

Ogorodniku it is desirable to determine before the beginning of spring work, the seeds of which varieties of tomatoes will be optimal for his plot. To get the early harvest in the open ground, as a rule, use a determinant variety of tomatoes: what is this you need to understand in order to avoid mistakes in the planning of planting.

Determinant and indeterminate - what does this mean?

When we buy the seeds of tomatoes, then on the packaging indicated - a sort of determinant (or indeterminate). What are the determinant and indeterminate tomatoes and what is the difference between them:

  1. Determinant varieties of tomatoes. The height of the bush is up to 110 cm, its growth stops after tying 3-5 fruit brushes. These varieties give a harvest earlier (stunted - 80-90 days after planting, medium-sized - after 100-110 days). Varieties often have poor resistance to disease.
  2. Indeterminant varieties of tomatoes. In growth are not limited, therefore the bush requires obligatory garter to supports. Have a later maturation, because the first brush is formed only after the eighth-tenth sheet. In the open ground such varieties are better to grow in the southern regions. High resistance to diseases of tomatoes. When grown in heated greenhouses can bear fruit all year round. Bushes require regular formation.

Determinant tomato varieties for greenhouses

Specific requirements are imposed on determinant tomato varieties, which are grown in greenhouses, where it is difficult to avoid high humidity and sudden temperature changes. Hothouse conditions favor the development of fungal and other diseases of tomatoes. Therefore, the hybrid yielding determinant tomato varieties for the greenhouse, resistant to phytophthora , rot and other diseases,

Sadly, it is impossible to obtain seed material from hybrid varieties of tomatoes. So if you plan to self-provide yourself with seeds, it's better to start conventional, rather than hybrid, varieties:

Determinant tomatoes for open ground

The determinant tomatoes for open ground proved to be excellent:

The most productive determinant varieties of tomatoes

Ogorodniki constantly strive to find the best determinant varieties of tomatoes, so that the palatability is at an altitude, and the yield is more - in fact, the plots of land allocated for garden crops, as usual, a small size. Of the most fruitful can be called:

How to grow determinant tomatoes in a greenhouse?

Growing determinant tomatoes in the greenhouse, although it requires effort, but not an impossible task. The main thing is not to thicken the planting, properly form a bush and necessarily tie the branches of the tomato to the supports, not allowing the bush to fall under the weight of the fruit. It is also important to avoid excessive humidity, using drip irrigation or plastic bottles deep in the soil with holes made, the water from which will moisten the soil at the roots, not evaporating from the surface.

Care for determinant tomatoes

Any tomatoes need constant care. Determinant tomatoes are not an exception, care of them is necessary throughout the entire vegetation process. It includes the following steps:

  1. Before planting seedlings and in the process of plant growth, fight pests. Huge damage to plants can inflict a bear , wireworm, shovel, whitefly.
  2. Conduct regular fertilizing with fertilizers with microelements.
  3. To eliminate the threat of phytophthora, air must pass freely between the plants. Tie the stems and large brushes to the supports. This will reduce the load on the stem and avoid its splitting or scrapping.
  4. Conduct regular top dressing of tomatoes with fertilizers with microelements.
  5. Watering is carried out closer to the evening, but so that the moisture on the leaves is dried before sunset.
  6. During the ripening of the fruit brush, we remove leaves under it (1-2 pieces per week, not more). Only without fanaticism: on the plant should remain at least 15-20 sheets, especially in hot weather. Leaves do not tear your hands, but cut them off so as not to injure the stem.
  7. To inhibit the growth of weeds, the root system did not overheat and moisture remained in the soil, mulch the soil around the plants.

Formation of determinant tomatoes

If you intend to harvest a good crop of the determinant tomato variety, it is not enough to imagine what it is like to know how to form determinant tomatoes in a greenhouse and in the open ground. Already before planting in the seedlings determine whether you will form a bush as one stem or in two or three - this determines the distance that must be left between the bushes when planting (the less on the bush of stems, the thicker you can plant tomatoes).

Bushes of early and supernumerous tomatoes are fertilized even before growth and may well do without formation. Tall - form in one stem, regularly breaking out stepsons. In middle-aged under the first flower brush leave the stepson to form a tomato "in two stems." When forming "in three stems" through 1-2 inflorescences, leave one more stepchild. The remaining stepsons are removed until they reach a size of 3 cm. When cultivating tomatoes in a greenhouse, the bush is formed into two or three stems, leaving up to seven fruit brushes on the plant.

Depending on the location of the planting of tomatoes (closed or open ground), from the months in which you plan to harvest, can you regularly engage in the formation of shrubs to you and should you choose - prefer an indeterminate or determinant variety of tomatoes: what is it - you you know and do not admit wrong steps, having grown a plentiful harvest of tomatoes.
