Indeterminate varieties of tomatoes for greenhouses: tall and high-yielding, names and characteristics

Many gardeners pay attention to indeterminate tomato varieties for greenhouses. When designing a greenhouse or greenhouse, you always want to grow something unusual. Large bushes appear, on which unusually large fruits ripen. Domestic breeders have long turned these dreams into reality. Complex hybrid varieties can grow to gigantic sizes in private or industrial production.

Definition

Indeterminate varieties have the main difference from their counterparts.The bush has the possibility of almost unlimited growth. It seems fantastic, but in practice we see a striking result. Tall tomato varieties for greenhouses are already growing in favorable conditions in Moldova, Ukraine, and Spain. Many domestic varieties feel great in the greenhouse conditions of central Russia.

Determinant crops dose growth. After tying a certain number of tassels (usually 4-5), they throw all their strength into the formation of fruits. There is some sense in this. Many crops produce large tomatoes in the greenhouse, due to the competent distribution of natural resources. We usually deal with early determinant varieties, for which the fundamental factor for rapid growth is the optimization of all processes.

Greenhouse selection

There is a wide variety of designs for greenhouses. Each of them has its own characteristics, but in order to grow tall tomatoes, it is best to make a choice in advance.

1. Design.
2. Height above 2 m.
3. Useable area.
4. Applied materials.
5. Price offers.

These are the main questions that arise when designing a greenhouse for a private household. A well-designed greenhouse will help increase productivity. Mobile structures are often used. You can search for a special video on how to grow tall tomatoes in a greenhouse.

Mobile structures have a number of advantages over their stationary counterparts.

1. At the end of the season, it is possible to dismantle the structure.
2. In the spring, you can change the location of the greenhouse.

This provides an excellent opportunity to competently manage your household. The soil preparation procedure is simplified, seeds can be sown directly in the greenhouse.And growing indeterminate bushes with this method is best. Competent crop rotation is provided, the amount of mineral dressings is reduced. The risk of over-enrichment of the culture with individual elements is minimized.

The following materials are used as cover for the greenhouse:

1. Glass.
2. Polycarbonate.
3. Plastic film.

They all have their advantages and disadvantages.

• Glass is an environmentally friendly material. Indeterminate tomato varieties feel great in such a room. But it may be unsafe during installation, dismantling of the structure.
• Polyethylene film is free from such shortcomings, but with frequent use it becomes cloudy, poorly transmits sunlight. This is true for both greenhouses and greenhouses.
• Polycarbonate.It has good characteristics as a building material for greenhouses. Typically, blocks having a honeycomb structure are used. They retain heat well, let in a wide range of sunlight. They are light in weight, easy to mount / dismantle if necessary.

Growing tomatoes in a polycarbonate greenhouse is the most preferable. When designing a greenhouse for nightshade crops, you can choose blocks with certain properties. For example, blocks with color additives filter sunlight and allow the culture to fully develop. For good development of seedlings and ovaries, blue and red light is useful. This spectrum is especially useful if the seeds are sown in a greenhouse. For the formation and growth of fruits - green.

UV exposure is best kept to a minimum. It inhibits the vital activity of the plant. All varieties of greenhouse tomatoes have delicate leaves that are sensitive to ultraviolet light.

Intense radiation can cause leaf burns. Given the above design features, it is possible to plan the planting of high-yielding tall tomatoes for the greenhouse.

Nuances

It is known that growing tomatoes requires special skills. Modern hybrid varieties do not grow in the wild and require special care. All gardeners are well aware that each variety has its own characteristics. When growing a single crop, consider:

1. Composition of the soil.
2. Time for planting seeds, seedlings.
3. Care.
4. Schedule of watering, top dressing.
5. Collecting, storing, processing crops.

Soil composition

Indeterminate tomatoes make great demands on the composition of the soil. They need a large amount of nutrients, which can only be obtained through special feeding.

• During the formation of green mass, before the first fruit set, potassium monophosphate is used. This element performs a transport function, transfers useful microelements to each cell of the plant. Contributes to the normal development of the tops. Growing indeterminate tomatoes in a greenhouse requires good seedlings. You can distinguish it by a strong stem, bright green color of the whole plant.
• Nitrogen begins to be introduced from the moment the fruit is formed. This helps them grow. The green mass has already formed, the planted plants give all their strength to the fruits. The ratio of the main active elements that allow you to get the largest fruits should be balanced. The nitrogen/phosphorus/potassium ratio is 1:1:1.
• During ripening, the ratio of the main elements is changed. In particular, increase the dose of potassium and phosphorus. Potassium gives resistance to diseases. Even very large tomatoes have a crumbly structure, a characteristic sweetish taste.The nitrogen/phosphorus/potassium ratio changes to 1:3:9.

The fertilization schedule may vary depending on the method of growing indeterminate tomatoes, vary within a small range. But how to grow plants and form the necessary order of feeding. Usually every 10 - 15 days make the recommended amount of nutrients. A certain planting pattern should be planned so that there is free access to the bushes for adjusting nutrition.

It is important not to overfeed the plant, an excess of fertilizer will lead to the accumulation of elements in the fruits, they will become non-edible.

Irrigation

Hybrid tomatoes love plenty of watering. Water dissolves various trace elements, promotes the flow of vital chemical reactions. A well-designed landing scheme suggests:

1. Access water to every plant.
2. Excludes its accumulation at the end of the bed.
3. Excludes moisture from entering the stems or leaves of the plant.

Following these three simple rules, you can get tall bushes with good yields.

It is recommended to design the greenhouse design with special plastic pipes. Small shapers are inserted into them, which supply water to each bush. Accordingly, the scheme for planting bushes is developed taking into account the nuances of irrigation. Pipes are easy to assemble / disassemble if necessary.

Sometimes you can pamper crops with sprinkling. This will wash away any accumulated dust or dirt from the foliage. I design the height of the greenhouse and plant the plants with this in mind. After sprinkling, the crop comes to life, the process of photosynthesis accelerates, growth accelerates.

It is best to carry out this procedure in the evening so that the morning or midday sun does not burn the delicate greenhouse foliage.

You can grow indeterminate bushes until late autumn. Before the first frost begins, it is necessary to drain the water from the pipes. It expands when frozen, which can damage the plastic. Finished pipes are dismantled and stacked in a specially designated room. It is advisable to protect them from sudden temperature fluctuations.

If individual watering is not provided, then tomatoes in the greenhouse can be watered from a hose. The main thing is that mineral fertilizers applied by the dry method are not carried over the beds by a stream of water. This can lead to starvation of some plants, due to the excessive consumption of minerals by others. We will get the effect of an unbalanced diet, tomatoes grown in this way will differ in their taste, commodity or other characteristics.

Fertilizers

With special care, it is recommended to treat the feeding of hybrid crops. All large-fruited crops are not distinguished by excessive modesty and are happy to eat the proposed elements:

• Overabundance of nitrogen. Leads to strong growth. It would seem that he should influence the development of bushes from the best side. Actually this does not happen. Incidence is on the rise. The leaves are suffering. Petioles are bent. The edges of the leaves are turning yellow.
• Overabundance of phosphorus. Metabolism of hybrids occurs more intensively than in conventional varieties. Hybrid large-fruited plants can literally be poisoned by phosphorus. Foliage suffers, culture aging occurs. The ends of the leaves gradually turn black.
• Overabundance of potassium. Noticeable by elongation of internodes, lightening of foliage, developmental delay. All this leads to the development of necrosis, dropping foliage. Large-fruited plants are especially affected by this; for full development, they need a normal metabolism.
• Overabundance of magnesium. The color of the foliage becomes saturated - dark. The leaves curl, elongate along the edges, die off. All interdeterminate varieties react to this by reducing yields and dropping fruits. In some cases, the culture may die.
• Too much calcium. Stimulates vigorous growth. Unformed bushes, with a lack of other elements, are unable to cope with such a load. Indeterminate varieties that are tall for greenhouses will respond to such stimulation with explosive leaf growth, leading to early wilting.

Feeding is best done individually, under the root of each plant. Use balanced formulations:

1. Ammophos.
2. Nitroammophos.
3. Diammophos.

Unbalanced fertilizers

These types of fertilizers are usually used when carefully studying the characteristics of crop growth. Here are some of the names that are widely used in all regions of the country.

For top dressing with phosphorus:

• Can be applied with simple superphosphate. Contains about 20% of the useful element. In extreme cases, double superphosphate is used, the element content is about 45%.

To apply potassium use:

• Potassium sulfate.
• Potassium sulfate.

Nitrogen fertilizers:

• Ammonium nitrate.
• Urea.
• Ammonium sulfate.

What to do if overfed

Of course, you are unlikely to be able to get the applied fertilizers from the soil mechanically. But you can always save the best varieties from excess elements, with the help of intensive watering. Water will reduce the concentration of substances, which will save the crop. But at the same time, you will have to re-coordinate the feeding scheme, form a new schedule.

Which variety to choose

When planning a sowing plot, every gardener wants to choose the best varieties of various crops.The desire is understandable, obtaining high yields is one of the main goals of vegetable growing. But there are many factors to consider when buying seeds. Many varieties of tall tomatoes produce excellent harvests in some regions, and absolutely do not take root in others.

Among the popular mid-early varieties of central Russia can be noted:

• Watermelon.
• Verlioka.
• Scarlet Mustang.
• Commissar.

Many ultra-early tomato varieties for greenhouses have taken root in vegetable growers' plots:

• Sweet bunch.
• Banana.
• Poznan.
• Mandarin.

Many tall varieties of tomatoes for greenhouses bear fruit in the harsh conditions of Siberia. If you create greenhouse conditions for development, then lighting becomes one of the main factors.The short summer is not conducive to planting late varieties. But the super early ones showed themselves perfectly in the extreme conditions of a short summer.
