Laying down weed mat is the easiest and often the most effective method for fighting weeds. It prevents weed seeds from germinating in the soil or from landing and taking root from above the soil. And because landscape fabric is "breathable," it lets water, air, and some nutrients to flow down to the soil to feed desirable plants.
Weed control mat works fine on its own, but it's usually best to cover it with a decorative mulch, rock, or other ground cover. The weed mat ground cover separates the cover material from the soil, keeping stone and gravel clean and slowing the inevitable breakdown of organic mulch. Black plastic (another type of weed barrier) performs a similar function, but plastic is prone to tearing, and it forms an impervious barrier that prevents water and air from reaching desirable plants.
Installing weed control mat fabric isn't much harder than spreading out a bed sheet, but it's important to prepare the ground properly to ensure a flat surface and prevent damage to the fabric. It's also important to overlap and secure the edges of the fabric to prevent weeds and cover material from getting through the seams.
