Disinfection of a polycarbonate greenhouse in the spring. Copper sulfate is used as. Fumigation of a polycarbonate greenhouse after harvest

Elevated temperatures and fairly frequent watering form conditions in greenhouses that promote the reproduction of all living things. To ensure good harvest, it is imperative to cultivate the land from diseases and pests. A special microclimate favorable for growing garden crops promotes the reproduction and spread of bacteria. In this case, the plants begin to grow poorly and bear fruit.

Greenhouse processing in spring before planting

In greenhouses, pests breed, which can be very dangerous for plants and often completely destroy crops. To avoid their appearance in a greenhouse, it is imperative to take appropriate measures.

Pest and disease control must be comprehensive and involve:

• Adequate amount of sunlight;
• Use different kinds drugs;
• Mechanical cleaning of racks and soil.

Should be located in a sufficiently well-lit area. In this case, sunlight will hit the plants for as long as possible. It is best if the greenhouse is facing south. Thus, sunlight will penetrate inside and warm the greenhouse well. Depending on the growth phase of the plants, periodic treatments should be carried out. It is necessary to take into account what kind of diseases and pests appear in a certain period, and, based on this, it is necessary to select a drug for processing crops.

In spring, stem pests are especially active, and soil cultivation must also be carried out to protect plants from cytosporosis.

In addition, mechanical cleaning of the racks is also important. To disinfect the surface, you need to use hot water with the addition of copper sulphate, bleach or formalin. Spring processing soil from diseases and pests is considered the most important, since the quality of the future crop depends on it, and also helps to replace several much later treatments. in spring, carried out before planting plants, it requires certain measures, without which it is almost impossible to get a guaranteed good result.

The reason for this is that certain conditions are formed in the greenhouse that are most comfortable for growing cultivated plants, as well as:

• Weeds;
• Pests;
• Pathogenic microorganisms.

You need to deal with pests constantly, and not only when they begin to harm. As soon as the snow melts, you need to start preparing for planting. All work carried out in the greenhouse can be divided into several stages, in particular, such as: cleaning the site, assembling the structure, washing all elements of the greenhouse and disinfecting the soil and premises. Disinfection of the soil should be carried out several weeks before the intended planting of seedlings. So, what if you plan to plant cold-resistant or early cultures, then the processing of the greenhouse should begin at the end of February. This will allow you to get full protection against diseases and pests for a long time and increase the germination and growth of plants.

How is the processing of a polycarbonate greenhouse in spring

At the beginning of the new summer cottage season, compulsory soil preparation and greenhouse processing are carried out. The processing of the structure, made of polycarbonate, allows not only to reduce the risk of infectious diseases, but also to clean the greenhouse of dirt, dust and rust. Important! When preparing a greenhouse, it is very important to follow all the required steps, since the success of growing garden crops depends on this.

The initial preparation and processing of the greenhouse, carried out in the spring, implies:

• Elimination of all plant residues;
• Replacement of damaged parts;
• Greenhouse construction cleaning.

Then it is imperative to thoroughly process the soil before planting seedlings in order to protect it from diseases and pests. When the ground warms up well enough, you need to dig it up and proceed to the main stage of disinfection.

Disinfection methods can be divided into several types, namely:

• Biological;
• Chemical;
• Temperature.

Each of the methods used has its own specific characteristics, and also implies the use of special means.

Greenhouse processing techniques in spring

Processing a greenhouse in spring involves the use of several different techniques, which are selected depending on the characteristics of growing crops. The biological method is considered to be the longest and most difficult method of processing in spring. However, it is the safest for plants and does not in any way affect the quality of the future crop.

The biological method of soil cultivation implies:

• Soil replacement;
• The use of green manure;
• Replacement of crops.

Siderata are special plants grown to fertilize the soil and suppress the growth of weeds. Not everyone can afford to replace the soil, which is why this method is practically not used. The temperature method is widely used, since in early spring you can freeze the ground a little. At low temperatures, many insect larvae and bacteria die. In addition, the soil can be slightly steamed.

To do this, pour boiling water over the ground and immediately cover it with foil. This method is quite effective, as it helps to destroy a large number of bacteria.

The most common method is chemical. It is necessary to select preparations for soil treatment very carefully, since there are chemicals of a wide spectrum of action, and those aimed at fighting only a specific type of pest.

How to treat a greenhouse in spring from pests

It is believed that the main processing of the greenhouse is carried out in the autumn, however, this is not entirely true, since processing is required in the spring. There are various technological methods of processing and folk ways.

The most popular are:

• Sulfur smoke bomb;
• Fugicides;
• Folk methods.

A sulfuric smoke bomb is often used in polycarbonate greenhouses, as this can be very harmful to glass. The impact of such a checker is based on the release of a special gas. It is harmful to absolutely all living organisms, which is why, during processing, you need to set fire to the saber, tightly close all windows and doors and leave the greenhouse.

Fugicides are very suitable for treating greenhouses made of polycarbonate.

One of the most popular remedies is a mixture of copper sulfate and lime. Since the composition is very caustic, precautions must be taken when preparing and processing the greenhouse. Fugicide treatment can only be carried out under the condition of a stable warm temperature.

Competent care: how to treat a greenhouse in spring from diseases

Many instead of chemical solutions use relatively safe folk remedies... Of the simplest and most affordable means, you need to allocate watering the soil in spring with boiling water or potassium permanganate. These products are very effective against many pests and bacteria. Of the safest methods are infusions of garlic, mustard and tobacco. With this tool, you need to treat not only the soil in the greenhouse, but also its walls and racks.

When growing plants in a greenhouse, it is very important to create the most favorable conditions, which is why it is imperative to cultivate the soil from various bacteria and pests.

For cultivating the land, tools such as:

• Fitosporin;
• Redomil;
• Mokosan.

When carrying out processing, it is advisable to first remove the top layer of the soil, and only after that carry out a thorough sanitization.

Correct processing of the greenhouse in the spring from diseases and pests (video)

Spring processing of greenhouses directly depends on the purpose for which it is carried out. It is very important to determine with which pest the fight is being carried out, and what result must be achieved in the end.

Attention, only TODAY!

Do I need to process the greenhouse if last season the tomatoes in it did not hurt or any pests were noticed? Let's put it this way: prevention won't hurt. But in the event that there was an outbreak of the disease, the processing of the greenhouse is mandatory, otherwise the risk of plant infection is very high. And it doesn't matter what kind of greenhouse you have: made of polycarbonate or glass and film.

How to process a greenhouse

There are at least 2 options: treatment with chemicals, or with the use of biological agents. If there were diseases and pests in the greenhouse, then chemical treatment is more often used.

Greenhouse processing with copper sulfate

The task is to wash the entire greenhouse from the inside with a solution of copper sulfate, or Bordeaux liquid, which also contains microns. This can be done by hand, with a soft cloth or sponge, or with a sprayer. With this procedure, part of the solution will inevitably fall on the ground. And here there are again two ways: either remove the layer of soil on which the copper sulfate has fallen, or leave everything as it is. Naturally, this is not fatal for people, but some of this chemistry, of course, through the fruits will get to our table.

Greenhouse processing with sulfur checker

This is a very effective method, but not sustainable at all. When such a checker burns, sulfur dioxide is released in the form of smoke, which penetrates into all corners of the greenhouse and kills all small pests and their larvae, and also affects life forms such as mold and fungus. During this treatment, the greenhouse must be airtight, there must be no cracks or holes in it. All garters and equipment in the greenhouse can be reused after such processing. The disadvantages of such processing: all living things in the upper layers of the soil are killed, the light transmission capacity of glass and polycarbonate, that is, the material from which the greenhouse is built, decreases.

Greenhouse processing with biological products

If there were no outbreaks of disease, then it is better to treat the greenhouse with phytosporin, or simply wash the walls with soapy water and then rinse with clean water. The garter must also be soaked in soapy water to disinfect.
It is advisable to process the wooden parts of the greenhouse, as well as the pegs, with plum thick.

Many gardeners prefer to add Baikal to the greenhouse soil in the spring, like Fitosporin, it carries beneficial bacteria into the soil, which not only make it clean, but also increase its fertility.

Now many people talk about natural farming and crop rotation on the plots. How can you achieve crop rotation in a single greenhouse, because you won't drag it from place to place. This is usually a serious structure, which is erected for several years. Changing the soil in a greenhouse for a new one is also too tedious task. The solution is this - after harvesting in the greenhouse, you need to pull out all the bushes and sow siderates in place of tomato beds. A mixture of white mustard and phacelia is best suited for this purpose. They will quickly rise and start growing. After a month and a half, all this green mass just needs to be plowed into the soil. Thus, you at least partially restore its fertility.

You can also sow greenhouses in greenhouses and in the spring, before planting a tomato. And when the time comes for planting seedlings, the mustard can be mowed, or left to grow further, freeing up only space for holes for tomato bushes. It has been noticed that if mustard grows in the greenhouse along with tomatoes, they are less exposed to late blight.

How to cultivate the land in the greenhouse for tomatoes in order to get a good harvest? Intensive cultivation of vegetables in a greenhouse is impossible without fertile soil. At the same time, the conditions of closed ground contribute to the massive spread of diseases and the reproduction of plant pests, many of which winter in the soil. Therefore, before proceeding with spring plantings in a greenhouse, you need to take care of the condition of the soil. It needs to be disinfected and fertilized.

Disinfection

First you need to collect and burn the remnants of plants, ropes, pegs and other debris. In January-February, do not throw snow into the greenhouse to freeze the ground as deeply as possible. Before treating the greenhouse with drugs, it is recommended to select at least 7 cm of the top layer of the earth.

In the spring, before planting tomato seedlings, the greenhouse is disinfected using the following means:

1. 1 tbsp. l. copper sulfate is dissolved in 10 liters of hot water and immediately sprayed on the ground. Processing is carried out a week before planting tomatoes.
2. 100 g of bleach is applied to 1 m² and covered with a rake. The soil is sprayed with milk of lime: 0.4 kg of bleach is mixed with 10 liters of water, allowed to settle for 4 hours. For 1 m² you need 2 liters of solution. Autumn processing of greenhouses allows an increase in the amount of lime by 10 liters of water up to 1 kg. A solution of copper sulfate can be added to the milk of lime. Processing is carried out no later than 1 month before planting tomato seedlings, since bleach inhibits the plants.
3. Sulfur smoke bomb. It must be placed on a non-combustible material, since it heats up very much during combustion. 1 checker is designed for 15 m² of the greenhouse. Fumigation destroys pathogens, mold, ticks, scares off mice. 2 days after disinfection, the greenhouse is well ventilated. Tomatoes are planted in a greenhouse when the smell of sulfur has completely disappeared. Please note that when sulfur is burned, sulfur dioxide is released, which, when interacting with water, forms sulfurous acid - an aggressive substance that has a corrosive effect on metal parts of the greenhouse.
4. Spill the soil with hot water (90 ° C) and immediately cover with foil. With this treatment, organic matter decays, the earth warms up. Plants can be planted in a week.
5. In a small greenhouse, the soil can be disinfected with a gas burner flame.

You can treat the greenhouse from anthracnose, which cucumbers and tomatoes have been suffering from recently, with the following tool: dissolve 1 tablet of Inta-vir insecticide and 2 tablets of Oxyhom fungicide in 10 liters of water. Spray on 15-20 m² of soil.

The walls and ceiling of the greenhouse also need to be disinfected: remove fungi, mold, dirt. When processing with a sulfuric smoke bomb, the soil and all internal surfaces of the greenhouse are disinfected. In other cases, if the air temperature in the greenhouse has not reached 10 ° C, the frame and walls can be washed with water from laundry soap or window cleaner. Don't forget to clean up tools, boxes, shelving, pots, and other inventory. If the temperature in the greenhouse exceeds 10 ° C, the use of the modern microbiological preparation Fitosporin will be effective.

The use of biological products

Fitosporin is a fungicide based on a natural bacterial culture against fungal and bacterial diseases. Phytosporin is used to prepare the solution and cultivate the greenhouse soil. various shapes release:

1. Phytosporin in powder in an amount of 5 g is dissolved in 10 liters of water and watered a week before planting seedlings.
2. Fitosporin in the form of a paste is diluted with water 1: 2, kneaded until the lumps disappear. 1 tbsp. l. the resulting concentrate is dissolved in 10 liters of water, watered with soil (10 liters per 3 m²), loosened with a rake and immediately covered with foil or spunbond. The resulting concentrate can be stored in a dark, cool (not cold!) Place.

This preparation is very economical: 200 g of paste (1 bag) is enough to process 100 m² of soil. It is added to the water when washing the greenhouse frame. It is important that the biological product can be used not only to prepare the greenhouse for planting tomato seedlings, but also during the growing season of plants, flowering and fruiting. It can be combined with fungicides, insecticides and growth promoters.

Thermal soil treatment can replace soil treatment with Flora-S, which is able to deoxidize the soil and restore its structure. A month before planting seedlings, water the soil with this agent at the rate of 10 liters per 3-3.5 m². Greenhouse vaults are disinfected with Fitop-Flora-S.

To suppress phytophthora spores, which are harmful to tomatoes, the soil in the greenhouse is sprayed with a solution of biological products Alirin-B and Gamair: 1 tablet of each agent per 10 liters of water. This agent is sufficient for 10 m², after which the soil is mixed, evenly distributing the agent. Bacterial spores germinate and secrete polyene antibiotics at a temperature of 18-25 ° C, it is this temperature regime that is favorable for the development of tomatoes. The use of biological products in the complex creates a powerful barrier for many pathogenic organisms. When working with them, use rubber gloves, a respirator, goggles and a hat.

When the soil in the greenhouse warms up to 10 ° C, a solution of the preparation Baikal EM-1 at a concentration of 1: 1000 is used to revitalize the soil and improve its fertility. The soil is loosened and watered with 2-3 liters per 1 m². The preparation Baikal EM-1 helps to restore the balance of microorganisms in the soil, to rapidly decompose and turn organic matter into humus. Plants can be planted in 10 days.

Siderata in front of tomatoes

It is possible to significantly improve the soil if, after processing with the above means, sow it with siderates - green fertilizers. Sowing them in the greenhouse in spring is necessary as early as possible, when there is still snow on the ground. In spring, green manure sows very densely. Before sowing, it is enough to loosen the soil with a flat cutter. After sowing, the seeds are covered with a rake, watered and covered with foil. The best green fertilizers for tomatoes:

1. White mustard - germinates at 3 ° C, grows very quickly, has a deep root system. By decomposing in the soil, it improves the living conditions of soil microorganisms and worms.
2. Phacelia - 45-55 days after sowing, forms lush bunches of greenery, not demanding on the soil. It has no "relatives" among garden crops, so it is considered a good predecessor for all plants. Phacelia embedded in the soil improves its structure no worse than cow dung.
3. Vetch - enriches the soil well with nitrogen, as it belongs to the legume family.
4. Lupine - 5-7 weeks after germination, its tops can be embedded in the soil. The plant has a powerful root that loosens the earth. The biohumus obtained from 1 m² of the aboveground part of lupine is equivalent to 4 kg of manure.
5. Rye is a soil orderly. Rye roots reduce the number of nematodes in the soil. In order for rye to grow a sufficient root system and a powerful green mass before planting tomato seedlings, it must be sown in the fall.

Green manure extract nutrients and moisture from the lower soil layers, do not require frequent watering. Before planting seedlings, they can be dug up, from this the soil will be saturated with nitrogen and calcium. Tomato seedlings can also be planted over the siderates by making holes. Green fertilizers will protect the roots from overheating, create a microclimate for young seedlings. The grown green fertilizers are mowed and left under the tomato bushes as mulch.

At an experimental station in the south of the country, in August, after harvesting, a mixture of oats, vetch and mustard was sown in the greenhouse, and on November 1, the plants were embedded in the soil. The next year, the tomato and cucumber harvest in this plot increased by 1-2 kg per square meter compared to another plot where humus was introduced into the soil. It follows that green manure must be used more widely.

Disinfection of the greenhouse and soil (video)

In structures closed type, in combination with high temperature and humidity, optimal conditions are created for the development of pests and various kinds of microorganisms. Therefore, twice a year, the greenhouse should be treated with some means.

Recommendations: what can be processed greenhouses and what drugs to use

Greenhouse processing should be carried out 2 times a year in spring and autumn, this applies not only to the soil, but in general to the entire greenhouse.

How to treat a greenhouse after winter: a general description

It is necessary to deal with the processing of the greenhouse not only in late autumn, but also in early spring before planting plants. In the spring, you should dig up the ground again, you should inspect the greenhouse itself, if there is any damage, you should fix it, and also wash the greenhouse both from the inside and outside.

Should wash warm water with soap, and the greenhouse should be wiped with a soft sponge or rag.

Do not use hard sponges, brushes, abrasive materialsas this could damage the polycarbonate.

After that, you can proceed to the following steps:

1. Processing the greenhouse from the inside with sulfur sticks, for 1 m 3 of the greenhouse you need about 50 gr. sulfur, checkers should be set on fire, and all doors and windows of the greenhouse should be tightly closed. The greenhouse should be kept closed for 3–5 days. You can also process the frame and the entire surface with a solution of slaked lime with copper sulfate, at the rate of 3 kg of lime, 500 gr. vitriol per 10 liters of water.
2. You can also use more modern biological products, for example, treatment with Fitosporin. Such drugs perfectly cope with fungal diseases, and suppress the growth of pathogenic microflora in the future. Processing is carried out twice, the interval between processing is 2 weeks.
3. If last season a large number of dying plants were noticed in the greenhouse, despite all efforts, then in this case the topsoil layer 5-8 cm thick should be completely replaced, since it is in this soil layer that the largest number of microorganisms and pests are located.

Using all these methods, you can perfectly prepare the greenhouse for the next summer season, and get healthy and strong plants and, as a result, a good harvest.

Tips: what composition to choose and how to treat a greenhouse made of wood

Many summer residents use greenhouses built of wood in their plots, but constant humidity and high temperatures create optimal conditions for the development of fungus, mold, rotting on the wood, and also the development of microorganisms harmful to plants.

To minimize education on wooden structures of all of the above, you must do the following:

1. Before construction or before replacing any parts, the tree should be treated with an antiseptic, and it is best to cover it 2 times, after the antiseptic has dried, the tree should be covered with paint for outdoor use, and at the same time, preferably in 2 layers. Instead, varnish can be used. Before construction, all wood that will be used in construction should be covered with 2 or even 3 layers of varnish.
2. You can use folk methods to protect the tree, for example, you can process all the parts with used machine oil. The oil is heated in a container to a temperature of 70 ᵒС, after which it is applied to the wood with a brush. Particular attention should be paid to joints and crevices.

In order not to use chemistry, many people burn wood with a blowtorch, and many also use bitumen for those parts of the greenhouse that are as close to the ground as possible.

To do this, bitumen is heated, then poured into a thin stream of cold diesel fuel.

The greenhouse is treated with this mixture, and it is possible to process it not only the lower parts of the greenhouse, but the entire frame as a whole.

High-quality processing of greenhouses and greenhouses

Many people use the same greenhouse to grow seedlings.

This, sooner or later, can affect the seedlings, it can get sick and die.

To avoid this, it is necessary to treat the greenhouse from microorganisms, fungi and pests.

And further:

1. It is important to alternate the crops that are planted in the greenhouse, as well as sow green manure plants (mustard, watercress) to the main crops, and they can also be planted in late autumn. You can cultivate the soil in a greenhouse with gray, copper sulfate. For the winter, you should completely open the greenhouse so that the cold destroys pests, as well as some microorganisms.
2. A wooden beam, from which, should also be processed for this, a solution of copper sulfate is perfect, they should be wiped, abundantly wetting the entire surface of the tree. The same goes for. But, in case of severe damage to the tree by fungus, rot, etc., the best way out is to build a new greenhouse or a new greenhouse.
3. If outbreaks of phytophthora were observed in the greenhouse, the entire greenhouse should be treated with Trichopolum, such a drug can be bought at a regular pharmacy. One tablet is dissolved in one liter of water, and the entire greenhouse is sprayed with this solution from a spray bottle.

The greenhouse should be kept disinfected.

Instructions: how to treat a greenhouse after harvesting in the off-season

When the summer season ends and the harvest ends, it is necessary to prepare the beds located in the greenhouse for winter.

After harvesting, it is necessary to remove the remnants of plants, remove all auxiliary material, such as slats, boards, ropes, and so on. All auxiliary material must be disinfected, for example, pour boiling water over (except plastic), the ropes can be disinfected by soaking them with chloramine or formalin can be used for disinfection.

If this is not possible, then it is best to burn all the auxiliary material along with the remains of plants.

In addition, you need to do the following:

1. To clear everything from dirt, remove the moss that has appeared, after that, it is worth rinsing not only with warm water with soap or with the addition of bleach, but also the entire frame, paying special attention to the joints and crevices. If the greenhouse cover is film, the film must be removed, fully expanded, rinsed and dried, and then stored.
2. The soil should be carefully dug, remove all plant roots, as well as all insect larvae that will be found during the digging. After that, the soil in the greenhouse should be sprinkled with ash, and after that, you can fertilize the soil with peat, humus or manure.
3. In order for the cold to finally destroy all harmful microorganisms in the soil in late autumn, it is worth opening the doors to the greenhouse. The soil will freeze, and this will kill the remaining harmful insects and most of the microorganisms.

Attention, only TODAY!

Not all novice gardeners or gardeners know that purchasing and planting original seedlings does not guarantee a rich harvest. To do this, it is necessary to carefully monitor the maintenance of favorable conditions for the growth of young plants: temperature, humidity, timely fertilization of the soil and processing it against the appearance of fungi and other pests. One of the easiest and effective methods for the care of the land - processing of greenhouse with copper sulfate in spring and autumn. Thanks to him, you can get rid of all types of fungi and larvae of various pests on the land.

Copper sulfate as soil fertilizer

All lovers of growing plants on their site are familiar with copper sulfate, since sooner or later every gardener or vegetable grower encounters this substance, regardless of the level of professionalism.

Copper sulfate is used as:

• Fertilizing the soil to improve yields;
• Treatment of soil from pests;
• Disinfection of trees and bushes from pests and various diseases.

The main advantages of this substance are ease of use, availability and low cost.

Copper sulfate is a blue powder substance. It contains crystals of sulfuric acid, as well as copper ions, which dissolve well in water without emitting compounds harmful to humans. Therefore, the harvest from the soil fertilized with copper sulfate is safe for human and animal consumption.

The interval between treatments of one plot of land with copper sulfate should be approximately five years. If you do this much more often, then there is a possibility of copper accumulation in the soil and the subsequent deterioration of the yield of some crops.

How to properly breed copper sulfate for greenhouse processing

Since copper sulfate is highly acidic, it is capable of spoiling plant leaves when it gets on them.

To avoid damage to plants in the greenhouse, or open ground after treatment with copper sulfate, experts mix it with lime, previously slaked. The resulting liquid is called Brodsky. The recommended ratio of copper sulfate to lime is 1: 1.

The dosage of copper sulfate can vary in accordance with the time of its production and the desired result from the procedure. The ideal time for soil treatment with this substance is early spring or late autumn.

We prepare the vitriol solution correctly:

• For pest-free soil, 75 grams of the substance should be diluted in a bucket of water;
• In the presence of insects in the soil, such as spider mites and others, the dosage of the powder, respectively, increases to 200 grams per bucket of water;
• must be treated with a solution of vitriol in a dosage of 100 grams per bucket of water.

Each manufacturer indicates the permissible dosage on the packaging of the substance, therefore, before preparing the solution, you must read the information provided. The finished solution can be stored for no more than a day. It is best to use this fertilizer before planting garlic and onions. It is quite useful to cultivate the land with vitriol to improve the yield of crops in small dosages, which are about 1 tablespoon per bucket of water.

How to properly cultivate the land with copper sulfate in a greenhouse

If a large number of insects and pests are bred in the greenhouse, then disinfection of the soil may not give desired result... In this case, some gardeners completely change the land in the building for a new and clean one.

It is possible to cultivate the land in combination with a solution of vitriol not only with lime, but also with formalin or special compounds purchased in the store. They should be diluted taking into account the recommendations indicated on the package.

• To prepare a solution of vitriol, it is necessary to dilute it and lime in separate containers, dividing a bucket of water in half;
• After dissolving and filtering the solutions, they should be drained into one bucket;
• Water the loose earth with the resulting product.

How the greenhouse is processed with copper sulfate in autumn and spring

Disinfection of soil with vitriol is effective in both autumn and spring. In the latter case, it is better to fertilize the soil a month before planting seedlings or on early stages sowing seeds. You can do this in February, subject to suitable weather conditions and freezing temperatures. If there is snow in the greenhouse, then it must be removed. For this you can use boiling water or a layer of peat, earth or ash.

Stages of greenhouse preparation in spring:

• Watering the soil;
• Coating material processing;
• Applying material to the ground;
• Overlapping doors and vents;
• Sealing cracks.

Before disinfection of the soil in the fall, it is required to prepare and thoroughly clean the site.

Stages of soil processing in autumn:

• Removal of plant and crop residues that were previously collected from the site, cleaning inventory;
• The soil for fertilization must be carefully dug up, and large lumps of soil must be crushed to achieve maximum looseness, and the remaining roots must be removed;
• If there is such a need, you should replace the land in the greenhouse with a new one;
• Thoroughly wash all surfaces, joints and glazing using special chemical compositions, process and fix it with boiling water;
• Irrigate surfaces and soil with lime solution for several hours.

Correct processing of the greenhouse with copper sulfate (video)

To fertilize soil with a low iron level, treatment with iron sulfate is used. This tool has its own characteristics and helps prevent the development of chlorosis in plants from a lack of nutrients in the soil. Those looking for material for the construction of a new greenhouse should pay attention to polycarbonate. It has special characteristics. In combination with proper care behind the structure and the plants planted in it and the timely feeding of the soil, as well as its disinfection, a person will be able to grow even the most capricious and atypical cultures for our climate.
