THAN COVER THE BEDS

New technologies, garden tools, as well as the efforts of the vegetable grower himself help to grow strong seedlings and get a good harvest in the future. To help gardeners, many devices have been created. One of them is the covering material for the beds, which is used in almost every technology of growing plants. There is a wide variety of canvases on the market in different sizes, densities and colors. Each material has its own composition, and, therefore, properties are also different. What happens and what the covering canvas is used for, we will now try to find out.

Difference in composition of covering material

On trade counters, various types of covering material for beds are presented to the buyer, differing in their composition and purpose. In general terms, they can be divided into two groups: Film and non-woven fabric. Each material has its own density, and is designed to perform specific tasks in the beds.

Non-woven covering material for beds

Sometimes gardeners among themselves non-woven fabric is referred to simply as a covering material, but most often it is called agrofiber. In retail outlets you can find such brands of nonwoven fabric as: Spunbond, Agrotex, Agrospan, etc. You should not look for differences between these names. This is one and the same agrofibre, only from different manufacturers.

A non-woven covering material is made of polypropylene, although it feels like a regular fabric to the touch. Despite its chemical composition, agrofibre is not toxic. The porous structure perfectly allows air and water to pass through, but retains heat over the covered beds. Non-woven fabric is resistant to UV radiation, which is why it has a long service life.

Agrofibre allows sunlight to pass through to plants, but prevents leaves from burning. Nevertheless, in extreme heat, the beds with greenhouses need to be opened slightly, otherwise the plantings will turn yellow due to dehydration.
Non-woven covering material is in great demand among vegetable growers, but they must be used correctly. Agrofibre is produced in black and white colors, as well as in different densities. Before using a nonwoven fabric, all these characteristics must be paid attention to.
The higher the density of the agrofibre, the better the material is able to provide heat protection to plants.

Polyethylene film

Sheltering greenhouses and sheathing greenhouses with foil is still popular among summer residents. The advantage of this covering material is its low cost, excellent light transmission, and the ability to protect plants from strong wind and frost. However, the high density of polyethylene also determines its disadvantages. The film does not allow air to pass through. To prevent the plants in the greenhouse from steaming out, timely ventilation is required. Inside the greenhouse, water droplets form on the surface of the film, creating a lens effect. The refracted rays of the sun burn the young foliage of the plants.


Plastic wrap is usually sold in rolls as a sleeve. If a large width of the covering material is needed, the sleeve is simply opened with a knife or scissors and peeled off. The variety of polyethylene covering material is much wider than agrofibers. Now we will consider the types of films for covering the beds:
Clear polyethylene is used as greenhouse sheathing and greenhouse cover to protect seedlings early in the season. The film prevents the negative effects of cold wind and rain on young plants. Polyethylene does not withstand snow loads, prolonged exposure to UV rays and mechanical stress with sharp objects. Usually this cheap shelter is enough for one season. 
Polyethylene with light-stabilizing additives has a long service life. The film is not afraid of exposure to UV rays, so it can last for at least three seasons. You can recognize such polyethylene by its yellow color. Over time, in the sun, it burns out, but does not lose its properties. The area of ‚Äč‚Äčapplication is the same as for transparent polyethylene. 
Reinforced film wins in strength . The material is resistant to mechanical damage, and new types are even capable of allowing moisture to pass through. Reinforced polyethylene is excellent for greenhouse cladding. 


Colored polyethylene in vegetable gardening is used for soil mulching. The film prevents the growth of weeds and the evaporation of moisture from the soil, maintains the optimum soil temperature. If the colored film is laid out along the aisles between the beds, you get a clean path without grass. In agriculture, hay and other objects are covered with colored films for winter storage. 
The black film stops weeds 100%. Used for soil mulching. Due to its resistance to sun damage, black film is used in strawberry cultivation technology. The method is the same as when using black agrofibre. On the farm, black film is used in the construction of decorative reservoirs in the country, where it serves as a bottom waterproofing. 
Black and white polyethylene has a double effect . Most often, the soil inside greenhouses is covered with a film. When laying, make sure that the dark side is on the ground. This will prevent weeds from growing. The white side of the film is placed on top. It will reflect excess sunlight. 
The film with air bubbles is characterized by a high thermal protection index. The material is used to shelter greenhouses or greenhouses, and then only in the northern regions. Sometimes bubble wrap can be found inside the package of fragile goods.
