Garden centers offer gardeners a variety of non-woven materials for insulating plants. We will understand which of them are intended for what.
1. Thin materials with a density of 13 to 30 g / m2 * (the most common option is 17 g / m2). used for light beskarkasnyh shelters. They can be placed directly on the leaves, and they let the light in well. Such a “non-wrap” will protect crops and planted seedlings from small changes in temperature, humidity, as well as pests (it is especially good for sheltering cabbage during the flight of cabbage-butterflies).
2. Materials of average thickness (35-45 g / m2) are used to cover crops and seedlings in small frame greenhouses. They miss the average amount of light, but pretty well protect plants from frost. It is useful to use them when planting seedlings of heat-loving crops in temporary spring greenhouses and greenhouses (material is removed when heat arrives, after 1-3 weeks), seasonal coverage of stationary greenhouses in regions with plenty of sun, winter plant protection (2-4 layers).
3. Thick white covering materials of white color (45-60 g / m2 and more) possess high heat-insulating characteristics, but do not transmit light well enough. They are best suited for winter shelter of roses, clematis and other insufficiently winter-hardy crops, as well as for emergency (for several days) protection of any plants from frost.
4. Thick covering materials of black or brown color (60-80 g / m2 and more) do not let in light, but let water through. As a rule, they are used as mulch coatings. If you spread out such a “non-fabric” between the rows, on the garden paths, in the near-trunk circles of trees and shrubs - you will not have to engage in exhausting weeding.
Choose materials that are uniform in density and made from the finest possible yarns. Compared to the coarser, they are less blown by the wind and better retain heat. Pay attention to the resistance of the selected “non-woven” to ultraviolet radiation (this parameter is usually shown on the package). White materials, as a rule, are resistant to sunlight, but among black ones there are also those that quickly lose their strength in the light.
* The figures indicate the weight of one square meter of nonwoven fabric. Accordingly, the larger they are, the thicker the material is.
