Weed mats need to be thick enough to be able to prevent light from reaching the soil. Even the slightest sliver of light can start germination, which will cause weeds to grow. This weed mat all but guarantees, however, that the weeds don’t end up growing any time soon. The thickness of the weed mat is more than enough to stop light from entering, preventing any weed germination from occurring.
The thickness of the fabric isn’t the only feature worth writing home about, though; the fabric itself is also environmentally friendly, so you can place your plants right next to the fabric with no issue at all. You can even cut a hole in the fabric and let a plant growing through it, and it’ll be completely safe. Unlike the potential dangers of herbicide, landscape fabric such as this are a much, much safer alternative.
