Abstract
Abstract A mulch product comprising an open-mesh fabric having knittedly inter-connected longitudinal and transverse yarn elements and a multiplicity of parallel strips of paper or other suitable material secured to a surface of the knitted fabric so as to form a laminated product wherein displacement between the strips and the knitted fabric in a direction parallel to the longitudinal elements of the knitted fabric is substantially prevented when the fabric is stretched in a direction at right angles to the longitudinal yarn elements and wherein one or both edge portions of the strips are free to move away from the fabric.
