Proper preparation of the greenhouse for the winter season is the key to a future harvest.
Careful treatment of the structure from the inside prevents the development of diseases and the appearance of pests in the next summer cottage season.
Preliminary preparation of the greenhouse
Before starting the treatment, a thorough cleaning of the greenhouse is required, reminds the expert of the online publication "BelNovosti", scientist-agronomist and landscape designer Anastasia Kovrizhnykh.
Plant residues are removed completely, including fallen leaves and small parts of stems.
The internal surfaces are cleaned from dust and dirt with a damp cloth or brush.
Chemical treatments
Copper sulfate is considered a classic means for treating greenhouses. The solution is prepared at the rate of 100 grams of the substance per 10 liters of water.
The treatment is carried out using a sprayer, with special attention paid to the joints and corners of the structure.
Biological drugs
Biological products are a safe alternative to chemicals. Fitosporin helps fight fungal diseases.
Trichodermin protects against pathogenic microorganisms. The preparations are applied in accordance with the manufacturer's instructions.
Traditional methods of processing
Lime solution is a traditional method of disinfection. Whitewashing protects the greenhouse from fungus and gives the structure a neat appearance.
Mustard powder diluted in water repels pests and disinfects surfaces.
Sulfur fumigation
The method of fumigation with sulfur checkers is recognized as one of the most effective. Sulfur destroys fungal spores, pests and their larvae.
The procedure is carried out in windless weather with the windows and doors of the greenhouse closed.
Soil cultivation inside the greenhouse
The soil requires special attention when preparing for winter. Potassium permanganate, diluted in water to a dark pink color, serves as an excellent disinfectant.
The solution is applied using a watering can, the consumption is 5 liters per square meter.
Prevention of rodent infestations
Mice and rats often choose greenhouses as a place to spend the winter. Laying out aromatic herbs (wormwood, tansy) scares away rodents.
Ultrasonic repellents can be installed around the perimeter of the greenhouse.
Processing of the structure
The greenhouse frame needs to be thoroughly disinfected. Metal parts are treated with a solution of copper sulfate.
Wooden elements are covered with an antiseptic compound to protect against rot and mold.
Important nuances of processing
The air temperature during processing should be above zero degrees. Work is carried out in dry weather for better absorption of the preparations.
The procedures are repeated after a week to achieve maximum effect.
Seasonality of work
The optimal time for greenhouse treatment comes after the harvest has been completely collected and the structure has been cleaned.
Work is usually carried out at the end of September or the beginning of October, when the air temperature remains positive.
