Caring for tomatoes in greenhouses. Caring for Tomatoes in Greenhouses: Detailed Instructions

When growing tomatoes, there are many nuances: proper planting and watering, pinching, feeding, maintaining humidity. Each procedure is able to influence both the quality and the quantity of the harvested crop. To reap a rich harvest, you need to pay attention to vegetables and promote their growth.

General requirements for growing tomatoes in a polycarbonate greenhouse

Greenhouse cultivation of crops is slightly different from outdoor cultivation. The crop in the greenhouse ripens faster, and the taste of the fruit is more juicy and rich. However, there are requirements for growing tomatoes in a polycarbonate greenhouse that should not be neglected:

• maintaining the temperature at the level of 22-26 degrees Celsius;
• pre-treatment of land and seeds before sowing;
• landing is carried out no later than the beginning of summer;
• further care of seedlings.

The polycarbonate greenhouse begins to be prepared in the fall. After harvesting, the walls are washed with clean water to collect settled dust and earth. Then they are treated with a weak solution of potassium permanganate to prevent the development of harmful bacteria and microbes. If holes or holes appear in the polycarbonate during the winter, they are sealed. In spring, the treatment is repeated a week before planting.

The greenhouse soil is dug up in autumn. They break up large clods of earth, add chicken at the rate of one bucket per square meter and superphosphate (1 glass per square meter). During the winter, fertilizers are absorbed into all layers of the soil, which increases its fertility.

With the onset of spring, starting from the second half of April, they begin to re-dig up the soil. Peat and river sand are added to the soil, humus can be used. Since tomatoes respond well to organic fertilizers, furnace ash is introduced into the ground. One cup of powder per square meter. Ash can be prepared at home by burning pine, birch, pine needles or spruce branches. The resulting coals are crushed to a powder state.

If the soil has a poor mineral composition, it is increased by adding crushed eggshells to the soil. It serves as a natural source of calcium, replenishes the supply in the earth. The consumption rate is a glass of fertilizer per square planting meter.

To cultivate the land from pests and viral diseases, dilute a teaspoon of copper sulfate in a bucket of water and water the soil in the middle of spring, repeat the procedure after 2 weeks. Copper sulfate can be replaced with potassium permanganate by mixing 5-6 powder crystals with 5 liters of water.

Ash is also sold in stores, garden products, it is already packaged in bags and crushed into a fine powder, so it is convenient to use.

Variety selection

From the whole variety of varieties of tomatoes, they choose exactly the one that will suit the climatic conditions of the region, have a high ability to resist viruses. Another indicator by which the variety is determined is the purpose of the fruit. If you plan to preserve tomatoes, then preference is given to varieties with hard skin and dense pulp. The shape of such tomatoes is small, and the weight is up to 100 grams.

These varieties include:

Tomatoes with fleshy flesh and thin skins are better suited for making salads, getting tomato juice. They are large in size, and the weight of some fruits can reach half a kilogram or more. Prominent representatives of fleshy varieties are:

How to prepare seeds

A growth stimulant can be added to a seed germination dish. It will accelerate the growth of seedlings and contribute to the development of the root system.

Planting material is soaked in potassium permanganate. The solution has an antibacterial effect and prevents the emergence of pathogenic microflora on future seedlings. In addition to effective disinfection, potassium is useful for the seeds themselves, it nourishes them and accelerates the process of future germination. Next, the seeds need to germinate: pour a little warm water in a saucer and put the seeds in it for 2 days. On the third or fourth day, the protective shell cracks, a sprout is visible. The landing itself will begin shortly.

Landing dates

In late February and early March, most gardeners start sowing seeds in the ground. This period allows you to get grown plants by the end of April, which are ready for transplanting into a greenhouse. Later than mid-March, you should not start planting seeds; it is better to purchase ready-made seedlings.

Prepare the soil mixture: fill the container with garden soil, mix peat and sand in equal amounts. The earth is watered and the tomato seeds are pressed into the moist soil, retreating from the previous seed at least 5 centimeters. Planting depth should not exceed 1 centimeter, otherwise the seeds will germinate for a long time. For seedlings, you need to create greenhouse conditions, so the container is covered with a film on top, but several small holes are made in it.

How to grow tomatoes in a polycarbonate greenhouse

For successful cultivation of crops in greenhouse conditions, you need to prepare good strong seedlings. Most of the characteristics of future fruits depend on its quality: their color, shape, taste, ripening period. Already grown plants take root better in the ground and do not die if the correct technique of agricultural cultivation is observed.

Growing seedlings

After 7-10 days after planting the seeds, the first sprouts hatch on the surface of the earth. They increase in size every day, after 2 weeks leaves form on the plants. When the development of the second leaf begins, the seedlings dive into individual cups. Seedling helps prevent overstretching of the stems and also allows the root system to develop.

Tomato seedlings are looked after: spraying and watering are carried out once a week. It is not necessary to overmoisten the soil, excess moisture can provoke the formation of rot or fungal infections. The soil is watered when the layer of earth at a depth of 5 centimeters is already dry.

On the May holidays, seedlings are accustomed to the ambient temperature. She is put up for several days on the balcony or transported to the country. Hardening tomatoes enhances their immune function and also reduces stress when transplanting to greenhouse conditions.

Scheme of planting tomatoes in a carbonate greenhouse

Planting tomatoes should be started on a cloudy day and in the morning. Holes are dug in the greenhouse with a depth of no more than 20 centimeters. The distance between adjacent holes should be at least 50 centimeters. The planting pattern is selected depending on the ease of maintenance, but most often bushes are planted in rows. Up to 4 plants per square meter. If you plant a larger number, then with the growth of the branches of neighboring bushes will be confused with each other, and the root system will not have enough space for development.

After digging the holes, half a glass of ash is poured into each of them. Ash contains a large amount of organic matter and minerals, accelerates the process of engraftment of seedlings and its growth. The bush is removed from the container along with the earth and the roots are placed in the hole. Cover with soil so that all the leaves are on the surface of the earth. After planting, tomatoes are watered with cool water, at least half a liter per plant.

Tomato care

The quantity and quality of the crop grown depends on the proper care of the crop. Tomatoes are watered and fed, and also tied up and stepchildren. Each stage of cultivation is important in its own way and cannot be excluded.

Watering tomatoes in a polycarbonate greenhouse

Tomatoes are considered a moisture-loving crop, but they do not tolerate the bay. After planting, it is enough to water the seedlings 1-2 times in 10 days. Watering is increased up to 2 times a week, when the summer time comes, and the temperature in the greenhouse rises. During flowering and fruiting, plants are watered every other day. You can use a hose, but be sure to adjust the water pressure so as not to damage the roots. It is necessary to water in the morning or in the evening, a thin layer of mulch is placed on moistened soil so that moisture remains in the ground as long as possible.

Attention!

Sawdust or straw mixed with peat is suitable for mulching the earth.

Sprinkling tomatoes increases the humidity in the greenhouse, protects the leaves from drying out. After irrigating the bushes, the windows and doors in the greenhouse are opened to improve air circulation.

Do I need to tie

Garter is a mandatory procedure when growing tomatoes. When the bushes get stronger and continue to grow, they need support. Some varieties reach a height of 1.5 meters, without a garter, under the weight of the fruit, the stem cracks and breaks, the tomatoes do not ripen to the end, and the bush itself dies. In the greenhouse, they are tied to a trellis. A wire is pulled over the top of the greenhouse, strong threads or long fabric flaps are tied to it. The other end of the flap or thread is tied to the top of the bush so that the plant is pulled up.

Instead of a trellis, you can tie the plants to a long wooden support. It can be a stalk from a shovel, rake, any long stick. Its height must be at least a meter. The stick must be firmly fixed in the ground so that it stands steadily and does not lean.

When to pinch tomatoes in a greenhouse

As the stem grows in the axils of the leaves, new branches are formed - stepchildren. They need to be removed in a timely manner, since stepchildren require additional nutrition, worsen yields and lead to late ripening of tomatoes. A tomato bush is formed depending on the variety grown, but not more than 2-3 stems.

Especially actively shoots are formed before flowering. Every day or every two days the bush is inspected. If stepchildren are found, they are pruned. It is desirable to remove excess shoots in the morning. Cut off the stepson to the very base with a pruner or a sharp knife. Juice is released at the cut site, the cut is immediately cauterized with hydrogen peroxide.

The juice released from the stem is toxic to the skin and can cause an allergic reaction.

When and how to feed

Top dressing is considered the most faithful helpers for getting an early rich harvest and tasty tomatoes. The culture can be fertilized with various mineral and organic additives. Each fertilizer must be used at a specific time. You can not thoughtlessly use top dressing, before use, you need to study the properties. Feeding tomatoes is carried out in 3 stages.

At the first stage, the main effect of fertilizers should be aimed at activating the growth of the stem, building green leaves and developing roots. From mid-May until the end, the first fertilizing with nitrogen fertilizers is carried out.

Prepare fertilizer:

• 10 grams of nitrophoska;
• 10 liters of water.

The ingredients are mixed and immediately after preparation, the plants are watered under the root. Re-feed with nitrophoska after another 2 weeks. The term of use of the additive is the beginning of May - June.

The second stage occurs before flowering and during its time. This period is important in that the laying of future yields is taking place. For top dressing, mineral fertilizers based on potassium and phosphorus are used. It is they who will determine the future taste of the fruit, accelerate the onset of fruiting.

The feeding recipe is as follows:

• st.l. potassium chloride;
• st.l. superphosphate;
• 10 liters of water.

Water the tomatoes with a freshly prepared mixture once every 10 days throughout the entire flowering period.

You can replace the mineral components with organic top dressing. Mullein has become widespread among gardeners. It is diluted with water in a ratio of 1:10 and insisted for a week in a warm place. The mixture should acquire a light green hue when it is infused, it is diluted with water 5 more times and watered under the bushes. Fertilizing with mullein is carried out from the beginning of summer until fruiting.

The third stage is at the time of fruiting. In order for a lot of tomatoes to grow, nitrogen fertilizing is repeated, but in combination with potash fertilizers. Potassium nitrate is perfect, as both substances are present in it. Prepare fertilizer:

• 10 grams of potassium nitrate;
• 10 liters of water.

The powder is dissolved in water and the soil around the tomatoes is poured with a solution. Top dressing with potassium nitrate is carried out 2-3 times during the formation of ovaries, fruit ripening.

The third stage is considered optional, if the fruiting proceeds abundantly, and the tomatoes ripen of high quality, then there is no need to feed. An excess of nitrogen and other mineral additives adversely affects tomatoes: the earth begins to turn sour, the porosity of the soil is disturbed, and the bushes themselves may turn yellow or begin to dry. If after fertilizing the condition of the seedlings worsens, then it is better to refuse the additive. For the entire spring-summer season, the number of dressings should not exceed 4 times.

How to get an early harvest

In order to collect the first fruits by the beginning of summer, it is necessary to plant varieties with an early ripening period. These are the Golden Brush, Early Greenhouse, Tangerine, Present, Sugar Plum. Peak fruiting in early ripening varieties occurs in late June-early July.

Early transplantation of seedlings in greenhouse conditions (end of April) can contribute to the appearance of a crop in the first half of summer, however, the temperature of the earth during planting in April should be at least 15 degrees Celsius. At lower soil temperatures, there is a risk that the plants may freeze, and fruiting, on the contrary, will be much later than the stated period.

For a quick harvest, you can prepare a nutritious yeast top dressing. For her you will need:

• a pack of dry yeast;
• 10 liters of warm water;
• a tablespoon of sugar.

All ingredients are mixed, infused for 2 hours and seedlings are watered under the root 2 weeks after transplantation. Such top dressing allows you to significantly bring fruiting closer, the harvest will appear 2-3 weeks earlier than planned.

Diseases of tomatoes in a polycarbonate greenhouse

The main problems that have to be faced when growing tomatoes include various diseases. Their nature of occurrence may be different, depending on the pathogen. Infection occurs through the ground or from neighboring plants, often insects carry viruses. You can recognize this or that disease by its appearance: blotches, spots, rot can form on tomatoes, and then the bush begins to fade. To start fighting the disease, you need to know the symptoms of infections.

late blight

The most common diseases include phytophthora. The cause of the disease lies in the infection of tomatoes with a fungus. It lives in the soil, survives the winter frosts well, and in the spring it activates and affects the culture. The fungus can be transmitted from potatoes and cucumbers.

The disease can be recognized by the formation of a white coating on the back of the leaves. Blurry brown spots begin to appear on the stem, then they pass to the leaves. Seedlings wither every day, and then die. Phytophthora development is facilitated by high humidity, spring and autumn frosts. The careless use of nitrogen fertilizers also leads to the emergence of a dangerous fungus.

As soon as the first signs of the disease are found on the tomato, treatment begins. Diseased areas of the plant are cut and burned. 5 grams of Fitosporin are diluted in 10 liters of water and healthy shoots are treated with the resulting solution. Phytosporin can be replaced with Ecosil, it protects healthy plants from fungal infection. 15 drops of the substance are dissolved in 3 liters of water and irrigated tomato bushes.

For the prevention of late blight, spraying with an iodine aqueous solution helps well. Take 10 milliliters of iodine in a bucket of water and irrigate the tomatoes 2 weeks after transplanting into the greenhouse. Repeat treatment after 10 days.

At the beginning of fruiting, you may encounter a dangerous disease called necrosis. Brown spots appear on the stem, then they crack. From the cracks formed, a white liquid flows out - the juice that is contained in the stem. After some time, the seedlings dry out from the loss of juice and die.

The causative agent of the disease can be present on the seeds, live in the soil. Sometimes infection occurs through garden tools or from neighboring crops. The incubation period is 2 weeks. Then there are signs of wilting.

It is no longer possible to save tomatoes infected with necrosis. They are dug out of the ground along with the rhizome and thrown away. The remaining tomatoes must be treated with a fungicide. Narcissus is used to treat stem necrosis. It significantly reduces the risk of infection by providing plants with normal growing conditions. For irrigation, dilute the solution to a working concentration of 0.25% and irrigate the plants. Part of the solution is used for watering the soil.

Regular ventilation of the greenhouse, infrequent watering will help to resist necrosis. Boric acid is often used to prevent this disease. A tablespoon of the substance is diluted in a bucket and sprayed tomato bushes a few days after transplanting into the greenhouse.

Septoria

In another way, the disease is called dry spotting. An infection appears throughout the bush, gradually affecting its parts. The disease begins mainly with the leaves: brown spots appear on them, they increase in size and acquire an oval shape. The surface of the stain has a velvety texture. The leaf is slowly dying. On the stem and fruits, such spots appear later.

Septoria is often transmitted to tomatoes from potatoes. The carrier of the disease are fungal microorganisms, their reproduction occurs by spores. Like all fungal infections, septoria progresses with frequent watering and high humidity. The disease is considered severe, a diseased plant cannot be recovered. The only way out is to save still healthy tomato bushes.

Sick shoots are immediately isolated from the rest. For treatment, fungicidal preparations are used - Kuproksat, Acrobat, Skor, Ditan, Metaxil. Any of the listed funds is diluted in the proportion indicated in the instructions for the drug. Fungicides can be used not only for treatment, but also for spring treatment for diseases.

Attention!

When breeding and watering with fungicides, gloves and goggles are used.

Blossom rot

The disease most often occurs due to improper care of tomatoes. With a lack of moisture in the soil, the root system begins to absorb water from the fruits and leaves. The pulp and stem begin to dry out, and a brown spot forms on the fruit, which grows in volume. Tomatoes infected with rot are not suitable for consumption.

To cure the culture, normalize watering. For prevention, use copper sulfate or irrigate tomatoes with a pink solution of potassium permanganate. Strengthen the immune ability of tomatoes nutritional top dressing. Calcium nitrate (10 grams) is mixed with potassium chloride (30 grams) and the substances are dissolved in a bucket of warm water. Feed the tomatoes with the resulting solution during flowering and during fruiting.

root rot

Rot or in other words "Black Leg" is a fungal infection. Transmission to tomatoes is possible from the soil and neighboring plants. A diseased plant cannot be treated, as it is completely affected by fungal spores. At the initial stage of development, gray spots form on the tips of the leaves, then the spot covers the entire surface, and the leaf dries. Gradually, root rot affects the stem and fruits.

In case of infection, the entire infected bush is dug up and burned. The land in which the diseased plant grew is shed with any fungicide. The remaining tomatoes are treated with antifungal drugs, for example, Rossa or blue vitriol, diluted in water to a concentration of 5%.

Other fungal diseases

Fungal infections include alternariosis - a less severe form of the fungus than the listed varieties. Alternariosis appears 10-14 days after infection. Signs are yellowed leaves and a sluggish stem that does not hold its shape well. If the tips of the leaves begin to turn yellow, then they are cut off. The bushes are sprayed with potassium permanganate diluted to pink, and the ground is watered with Fitosporin.

White rot is less common on tomatoes, but the disease is easily spotted by the characteristic white bloom. The infection is difficult to remove, treatment is complicated by the fact that spores quickly spread throughout the plant. Cutting off infected bushes is still considered an effective way to get rid of rot. At the same time, healthy plants are protected from possible infection with the help of fungicidal agents.

fruit cracking

Unlike fungal and viral diseases, cracking of the skin is not so dangerous for fruits, but it reduces the shelf life and spoils the appearance. Especially large tomatoes weighing more than 300 grams suffer from cracking.

The reason may be an excess of nitrogen components in the soil, as well as a large temperature difference. Frequent evening watering and the use of dressings also provoke the formation of cracks, as the fruit rapidly increases in volume. Most often already ripe red tomatoes with a thin skin crack.

There is no cure for cracking. However, if you take the following measures, then trouble can be avoided:

• planting varieties with strong skins;
• use of drip irrigation system;
• soil mulching after watering;
• obligatory closing of the greenhouse at night.

The secrets of growing tomatoes in a polycarbonate greenhouse

Those gardeners who have been breeding crops for more than one year have their own secrets of growing crops. Most often they consist in maintaining warm climatic conditions, proper care of plants. In order for tomatoes to grow healthy, their condition must be checked daily. It is regular monitoring of the culture that allows you to notice deviations in development or growth, as well as take timely measures to eliminate the problems that have arisen.

How to take care in winter

When growing tomatoes in winter, the greenhouse should be well heated, the temperature should not be lower than 18 degrees Celsius. Of the varieties, preference is given to frost-resistant varieties that are able to tolerate frost well. Such varieties are Revermun, Sobeto, Carlson, Swallow, Vnukovsky.

Seedlings begin to grow from the end of November. By spring, with this planting time, you can collect the first tomatoes. Winter cultivation is practically no different from the usual. Tomatoes are also looked after: watering and gartering, pinching are carried out. After watering, the earth must be loosened. To enhance the process of photosynthesis, it is recommended to install containers or barrels in the greenhouse that contain liquid mullein. During fermentation, the fertilizer releases carbon dioxide, which enhances photosynthesis.

In winter, tomatoes may lack sunlight. For the growth of seedlings, artificial light sources are used - lamps, spotlights. In addition to light, they give off heat, which tomatoes need for development.

1. Do not plant tomatoes in the ground where nightshade crops were previously grown.
2. Water the tomatoes with exceptionally warm water.
3. For lush flowering and early yields, yeast top dressing is used. For a liter of water, take 5 grams of dry yeast and a teaspoon of sugar. Dilute the solution 3 times and water each tomato bush 2 weeks after transplanting into the greenhouse. Reapply top dressing no earlier than 10 days after the first.
4. If the harvest turned out to be rich and tasty, then seeds are harvested from the largest tomatoes. Choose a large ripe fruit and put it in the sun to overripe. Then the pulp is dipped into a glass filled with water and left for 2-3 days. Seeds are separated from excess liquid and cake, dried on a windowsill and stored in a dark and dry place. The following year, seedlings can be grown from them. Do not forget to disinfect the seeds before planting.

Caring for a culture is not difficult, but requires attention. You can not leave tomatoes unattended, you need to assess the condition of the plants daily, even if they have fruited. If all the conditions necessary for growing tomatoes were carried out correctly, then even with a small planting on a few square meters, the crop will exceed all expectations both in terms of the number of tomatoes and in quality.

In order for the yield of tomatoes to be very high, you need to organize the right system for caring for them, which involves performing certain actions.

Most importantly, it is correct, which is intended for growing in a greenhouse. There are a very large number of types of tomatoes with a variety of yields.
So:

• As a rule, these varieties are distinguished by the elasticity of the fruit.
• It is also necessary to build a greenhouse that, thanks to the material, could constantly maintain the same temperature regime and have high technical and operational properties.
• Next, you need to grow seedlings, or you can buy it. Who will be more comfortable at this stage. Accordingly, then you need to plant it correctly.
  There is a specific technology for this, which is not always suitable for all varieties.

Advice. growing tomatoes is best in a polycarbonate greenhouse. This material is distinguished by its properties and characteristics. The price for this type is low.

What is included in the care system

In order for, care must be appropriate.
It consists of:

• Creation of an optimal temperature regime.
• The right watering system that would be suitable for a particular variety of tomatoes.
• Top dressing.
• Self-pollination.
• Pruning.

To perform all such actions, there is a special instruction for each of them. Only with strict adherence to a clear sequence can you get a good crop of tomatoes.

Optimal temperature

There are varieties that can freely tolerate not too low temperatures, but there are also heat-loving ones.
Peculiarities:

• Very often, a novice gardener may be faced with the question of why tomatoes rot. Everything is very simple.
  If one mode is needed for growing tomatoes, and the actual temperature inside the structure is several times higher, then the process of tomato rotting will not be uncommon.

Advice. You need to grow tomatoes under a certain temperature regime, which ranges from 23-26 degrees Celsius.

• Only in such conditions that are close to the real summer temperature is it possible to grow this vegetable. How can such conditions be created?
• The design itself plays an important role in creating the optimal temperature regime, the coating of which must not only be durable, but also not let cold air in.

The process of heating the structure itself is carried out in several ways:

• Independent production of a potbelly stove and removal of pipes from it around the entire perimeter of the greenhouse.
• Use of electrical equipment: electric heating cables and electric boilers, etc.

• The use of gas equipment.

But here it is worth considering that the last method of the system can be chosen if there is a centralized gas pipe on the site and it is permissible to make a tie-in to it. It is not recommended to heat a room of this type from gas cylinders, as fuel consumption will be unjustified.

Correct and timely watering

Photo of irrigation organization

Why do tomatoes crack in the greenhouse? In most cases, this can be observed with improper and untimely irrigation of tomatoes.
If there is an excess of moisture, then many varieties are saturated, and stop growing, thereby starting to crack. If it is in insufficient quantity, then deformation of the fetus is also possible.
What is the best irrigation system to choose:

• It all depends on the type of tomato. Some of them are moisture-loving and require almost daily watering, and for some, one irrigation in three days will be enough.

There are several options for watering tomatoes in a greenhouse:

• Do it yourself with a bucket or hose. This process takes quite a lot of time and effort and at the moment is practically not used.
  You can meet a manual irrigation system only with a small area of ​​\u200b\u200bthe structure.
• Automatic equipment. There is a very wide variety of irrigation systems that are most commonly used in greenhouses.

Advice. In order to spend less energy on caring for greenhouse plants during their irrigation, it is best to use automatic irrigation, which, thanks to special equipment, can turn on and off on its own.

Eat:

• Subsoil irrigation.
• Sprinkler.
• Drip.

More:

• The subsoil irrigation system is a pipe that runs under the ground and the water from them flows directly to the root system of the tomato.

Advice. It is necessary to use this method of watering very carefully, since due to oversaturation with moisture there is a possibility that the root system will die.

• The sprinkler irrigation system is more modern and is most often used in greenhouses. Along the entire perimeter of the greenhouse, pipes for water supply are installed at a certain height, and all their ends have special nozzles. Water is supplied from above.

Advice. This method of watering is best used for moisture-loving tomato varieties.

• - the most economical way. Water is supplied directly under the stem of seedlings in small doses.

Advice. This method can be suitable for both moisture-loving and ordinary varieties of tomatoes.

The video shows all these irrigation systems for tomato seedlings in a greenhouse.

Top dressing of tomatoes

It is necessary to perform such actions only after the seedlings planted in the greenhouse are accepted. This will be evidenced by additional leaves on the trunk and the rapid growth of the bush.
So:

• As a rule, top dressing (see) is performed only twice. The first time after the seedlings have taken the soil in the greenhouse and the second - as soon as the fruits (strings) begin to appear.
  At one time, any top dressing should take no more than 0.40-0.45 kg per 1 weave of soil.
• Calcium or ammonium nitrate is used as a means, and preferably in powder form - when the fertilization process is carried out after the seedlings have taken the soil. The soil is sprinkled with this powder and watered.
  You can use these products in a liquid state and apply them in the process of watering tomatoes.

Advice. The concentration of any solution for feeding tomatoes should not exceed 0.3%.

• Do not fertilize immediately after the seedlings start. you need to initially do a soil analysis for the presence of nutrients in it. If they are in it in sufficient quantities, then the first feeding can be canceled.

Advice. There are some other methods that involve feeding the root system directly.
But, as practice has shown, it is best to apply fertilizers on top of the soil. In this case, its results can be seen two weeks earlier than the root one.

Self-pollination of tomatoes in a greenhouse

In principle, all varieties of tomato seedlings that are grown in greenhouse conditions are capable of self-pollination. The gardener only needs to plant them correctly inside the greenhouse, so that air masses can carry pollen from bush to bush.
Necessary activities:

• For this purpose, vents are provided in the greenhouse, which serve not only to ventilate the structure, but also for such purposes.
• Self-pollination consists in shaking pollen from flowers on a tomato bush with a soft stick (lightly hitting the bush) or simply shaking the seedlings. After that, the pollen should crumble to the ground.
• There is also a special tool that is sold in the form of a solution. tomato flowers can be dipped into it or simply sprayed.

Advice. Before such work, it is best to consult with a specialist in this field so that your wrong actions do not harm the plant.

Cutting tomatoes in a greenhouse

What is pruning a tomato in a greenhouse? This is putting in order by cutting off excess branches and leaves.
How to do it right?
Everything is pretty simple. Using a pruner, the lowest branches of the tomato bush are selected and cut off.
In some cases, the upper shoots are also cut off. It all depends on the growth of the tomato bush.

Advice. Such actions are very important in the quality care of tomatoes, and especially in the greenhouse. They help the nutrients to be extracted by the fruit of the tomato, and not by the bushes themselves.

Weak branches of seedlings are also subject to pruning.

General recommendations for growing and caring for tomatoes in a greenhouse

How to grow and care for them correctly? These questions are always of interest to beginner gardeners.
In the event that you are not aware of some of the actions for caring for tomatoes, then it is not recommended to perform them without prior consultation with a specialist. Care for tomato bushes can be anything.
The most important thing is high-quality soil in the greenhouse itself. Only thanks to its fertility is it possible to get an excellent tomato crop.
It is necessary to plant seeds for tomato seedlings closer to the beginning of spring, and in the middle of summer, ready-made bushes of small size are planted in the greenhouse soil. There they need to create all the conditions for normal growth.
