A weed barrier is a material used in gardening and landscaping to prevent unwanted plants, or weeds, from growing in a specific area. It is typically made from fabric, plastic, or biodegradable materials that block sunlight while allowing water and nutrients to pass through. This helps maintain soil health and reduces the need for chemical herbicides. Using a weed barrier can save time and effort in garden maintenance. By suppressing weed growth, it allows plants, flowers, and vegetables to thrive without competition for resources. Many gardeners choose to use a weed barrier in conjunction with mulch or decorative stones for added effectiveness and aesthetic appeal.
