Tips on product selection
Many hobby gardeners, who have too little time for gardening, lay a weed fleece on their plant beds. The material is in contrast to conventional film permeable to air and water. This is important so that the rainwater can seep in and the gas exchange in the soil is not affected. Weed fleece and other nonwoven products such as winter protection hoods for plants are made of plastic fibers such as polyethylene or polypropylene. The long and very thin threads are not interwoven, but form a felt-like structure. The quality of weed fleece is usually given in grams per square meter - the heavier, the thicker and more durable the material is.
For weakly weeded planting areas that are covered with bark mulch and barely entered, material thicknesses of 50 to 80 grams per square meter are sufficient. However, if the areas are heavily overgrown with root weeds, are more frequently entered and mulched with sharp-edged grit, qualities up to 150 grams are recommended. They show the best durability and resistance to the perennial shoots of couch grass, greed, horsetail and other unwanted bedding inhabitants. Note, however, that as the material thickness increases, permeability to air and water decreases, which can negatively impact the growth of ornamental plants in the bed. If the mechanical load is limited, it is often more sensible to lay a 50-gram two-ply fabric instead of a 100-gram weed fleece. It should be noted that you should always lay the nonwoven webs with a 10 to 20 centimeters wide overlap, which then quickly leads to a material thickness of 300 grams per square meter and more at these points.
The weed fleece is cut to fit the bed and the plants are set in small, cross-shaped recesses
Weed fleece or geotextile?
In the specialized trade also so-called ribbon fabric is often offered under the name weed fleece. It consists of thin and narrow, interwoven black plastic threads and is also called floor fabric or geotextile. You can use it just like real weed fleece to suppress wild herbs. Ribbon fabric is easier to cut, but has the disadvantage that it fray easily at the edges. It is not as permeable as weed fleece, but usually more UV-stable, a little more robust and also cheaper. Ribbon fabric is mainly used in professional horticulture to keep cultivated areas for container plants weed-free.
