Just think, but even 20 years ago, gardeners were not tormented by the question of which variety of tomatoes to plant - they simply did not exist. Now the seed market is flooded with a variety of varieties for certain climatic conditions, including for greenhouses. How not to drown in the flood of names and make the right choice?
- Indeterminate varieties
- Determinant varieties
- Types of tall tomatoes
- Types of determinant varieties
All experts agree that it is the indeterminate or tall varieties of tomatoes that are ideal for greenhouses. They are formed into 1 stem and its growth is not limited as long as there is space and favorable temperature conditions. Of course, they need more careful care, but at the same time, the yield increases significantly. In particular, with proper care and watering, you can collect up to 50 kg of tomatoes from a bush.
The main advantages of indeterminate varieties:
- The bush gives more yield due to more color brushes
- They are less susceptible to fungal infections due to the greater air intake
- Long fruiting phase, which allows you to enjoy tomatoes for a long time
- Bushes are much easier to form, since you only need to leave the stem without stepchildren
The disadvantages include:
- Tomatoes are very picky about heat and care, so they may not grow in all areas.
- Unlimited growth, not only in height but also in width, not suitable for small greenhouses and plots
- Due to early maturity, there may be such a minus as a different size of fruits on one bush.
In contrast to tall varieties, determinant ones do very well in different climatic conditions, they need less maintenance. But at the same time, they have limited growth and, consequently, a harvest. This species is also suitable for growing in greenhouses, especially if there is not a lot of space.
The main advantages of determinant tomatoes include:
- Early fruits. They ripen earlier than the identity ones, since flower clusters are laid through fewer leaves.
- High level of early harvests in a variety of climatic zones.
- A more harmonious return of the harvest - several brushes are tied at once and almost at the same time.
Cons of determinant tomatoes:
- The total yield is lower than that of tall ones, again due to the small growth of the bush.
- Diseases. These varieties are more prone to disease. Loaded with brushes, their resistance to viruses decreases. That is why these varieties need to be treated more with chemicals.
- Increased fertilization and mineral nutrition, again, due to the load of the brushes.
The main types of tall tomatoes
Of course, it is impossible to list all types of tomatoes, because every year breeders come up with more and more new hybrids. Let's try to list the main and most popular ones.
One of the most famous varieties of indeterminate tomatoes. Its bushes reach up to 3 meters. At the same time, it can be cultivated both in the greenhouse and in the open field. A high yield can be harvested from each square meter - up to 10 kg per bush.
Like all tall ones, it has an increased resistance to diseases.
De Barao is divided into several subspecies (pink, royal, gold, black, red, yellow) depending on the color of the fruit, but with the same characteristics - a large yield and high stature.
Also one of the leaders of tall tomatoes. It is ideal for growing in greenhouse conditions, while looking quite interesting. 3-meter tree with vines on which cherished tomatoes grow. From such a tree, you can get 1-1.5 tons of harvest. At the same time, the fruits have excellent taste, they can be stored for several weeks or even months with the correct content.
Fruits are formed on the 110-115th day of planting. Its excellent yield is successfully combined with another plus - the brushes are not refracted. The taste of tomatoes is excellent. Alhambra in greenhouses bears better fruit from April to January, while forming huge, ten-meter lashes. The fruits keep well for 3-4 weeks and tolerate long-term transportation.
The main types of determinant tomatoes
A classic to introduce an early, fruiting variety. A very early variety, the first fruits can be harvested after 90 days. On its branch 8 fruits are formed, weighing 100 g. The variety can be grown not only by seedlings, but also by planting seeds directly into the ground, while it has a high resistance to infections.
This is a mid-season variety, the fruits of which can be removed from the branches on the 100-110th day after planting. The average weight of such a fruit is 200 g. Due to its resistance to temperature extremes, it grows well, both in the southern regions and in the regions of the middle zone. With good care, gardeners collect up to 3 kg of fruits from one bush.
Hybrid Ivanhoe F1
Originally from Holland, tomatoes are loved by Russian amateur gardeners. Like all determinant varieties, Ivanhoe is unpretentious to the weather and easy to grow. The taste is much brighter than other greenhouse varieties of tomatoes, and the early fruits can be obtained already at the beginning of summer.
This variety is ideal for connoisseurs of natural cultivation - it does not require chemicals! In conclusion, I would like to note that experienced gardeners are experimenting with several varieties of tomatoes at once.
After all, they are all suitable for different climatic zones, where yield levels differ. When choosing a particular variety, you need to take into account the type of greenhouse and weather conditions. Also, do not forget about new products that are more productive and more resistant to diseases.
