Landscape fabric is constructed from woven fibers or manufactured as a solid sheet with perforated holes to allow water to soak through. Some brands offer UV protection to maintain the life of the fabric. It comes in rolls, typically at least 3 feet wide and anywhere from 50 feet to 200 feet, or more, in length.
Most gardeners agree that the best place for landscape fabric is around shrubs and trees where it can be installed and topped with quality mulch to hopefully last for years. Because it’s intended to be left in place, it’s not recommended for vegetable gardens or annual flower beds.
