To grow vegetables in the middle latitude of Russia, which is so necessary warmly, without such premises can not do. But creating comfortable conditions for plants, weeds and infectious pathogens feel great in greenhouses at the same time. There is a golden rule of prevention: it is easier to prevent than to treat later. Is it possible to plant tomatoes, cucumbers and peppers in one greenhouse, every gardener should know about this.
Initial stage: preparation and restoration of the greenhouse
At this stage, the following workloads should be completed:
1. It is important to review the integrity of the structure. If necessary, replace damaged parts of the frame.
2. Also pay attention to the condition of the coating. There should not be a hole in any case: you can restore the film by blocking it again or by applying latches with adhesive tape.
3. If in the fall not all plant residues were removed, then it is imperative to do this now. After all, pathogens and pests could overwinter in fallen leaves, shoots, branches.
4. Greenhouse coverings are usually washed with a soap-soda solution. But if it consists of polycarbonate, then cleaning should be done carefully: use only soft materials and do not use abrasive scratching substances.
Next, you need to dwell in more detail on how to cultivate the earth in a greenhouse. In the spring of pests and diseases, the sanitary soil treatment procedure is performed by several methods, which will be discussed later.
Greenhouse tillage options
When the greenhouse area does not exceed 30 square meters. m, boiling water is most often used. Hot water helps kill pests and many pathogens in the soil. In the southern regions with plenty of solar heat, a “wet bath” is often used. The essence of the method is as follows: the greenhouse is clogged so that the air in no way gets inside for a week, after filling the soil with water in huge quantities. During this period, many pests will also be destroyed. Cucumber care in the greenhouse must be done correctly.
For central regions and colder northern areas, of course, such a procedure is not possible. Therefore, there the method of replacing the upper soil layer will be especially relevant. They remove about 10 cm of soil, distribute it in the garden, and instead of the old soil, compost, organic fertilizers are introduced into the greenhouse and carefully digged.
It is possible to improve the soil under the cover in a natural way by planting special plants. Siderata is a solution to the problem for gardeners who are ready to wait with a large crop, since sufficiently large areas of the greenhouse will go under planting precisely such crops. For proponents of organic farming, this is the best way out.
To disinfect the soil often resort to chemicals. For soils with acidic environment, solutions of bleach are used. Experienced gardeners and garden hobbyists will tell you how to process a greenhouse in the spring from pests and diseases. Many of them use the old proven method of using effective copper or iron sulfate. As a prophylaxis, these agents fully justify their purpose.

It is important to remember that early chemical soil treatment is practically not able to have a negative effect on the growth of vegetable plantings.However, having missed the most suitable time for treatment with pesticides, do not despair, use folk remedies that are safer for plants. Many of them have proven effective in combating pathogenic bacteria. Among such natural preparations are onion and garlic infusions, mustard, tobacco dust.
How to disinfect greenhouse frames and cover?
The washed greenhouse design should also be disinfected. Not knowing how to do this, check out the recommendations below. It is believed that the easiest and most harmless way to prepare the greenhouse for the new season is to smoke fumigation. For this purpose, an ordinary bonfire is suitable, the smoke of which will just fall on the structure.
For one hundred percent confidence that pests and diseases will not be scary for your plantings, use a more effective sulfur fumigation. Sulfur anhydride penetrates deep into the soil and any places with difficult access, destroying all life in its path: insects, infections, rodents. However, this method is also quite dangerous for humans. Sulfur fumes pose a threat to the respiratory system of the body, contributing to the induction of bronchospasm.
In order not to harm yourself during the procedure, before treating the greenhouse in the spring from pests and diseases with the help of sulfur, take care to provide a gas mask, or at least a respirator. Ignite the sulfur drafts, starting from the farthest, to be at the exit as quickly as possible.
Another common option spraying is spraying the frame and coating with special solutions based on chemical or natural preparations. Chlorine lime and copper sulfate will also help to cope with the disinfection of the greenhouse. Such solutions process only the internal elements of the building.
Iron sulfate is especially relevant when trying to get rid of lichens and moss spores. It is possible to spray with the prepared solution only when the surfaces are completely cleaned of fungal growths.
A safer way for human health is the use of bio-compounds. Of course, in the presence of pests, they are less effective in comparison with chemistry, but for prophylactic purposes they are best suited, while also positively affecting the fertile properties of the soil.
Before treating the greenhouse in the spring from pests and diseases, think about why you will carry out the procedure - soil treatment or prevention.
