Landscape fabrics are used to prevent weed growth while still allowing air, oxygen and water to flow to and from the soil. Landscape fabrics are a chemical-free way to prevent weed growth, endearing them to eco-friendly homeowners. Landscape fabrics, once laid, also are a far less labor-intensive method to prevent weed growth, as they can be effective for several years, during which homeowners can expect to perform little or no maintenance.
In addition, many homeowners prefer landscape fabrics because they can help the soil effectively maintain moisture during dry periods, when gardens might otherwise be highly susceptible to drought. Once put down, landscape fabric can be covered with mulch to add aesthetic appeal.
