Abstract: A new and improved modular plant growth prevention apparatus is used in conjunction with a vertical surface extending vertically from the ground and includes a plurality of plant growth prevention modules which are placed on the ground a predetermined distance from the vertical surface. A plurality of first connector assemblies connect the plant growth prevention modules to each other. A plurality of second connector assemblies connect the plant growth prevention modules to the ground. Each of the plant growth prevention modules includes a vegetation-impervious horizontal portion for placement on the ground. The vegetation-impervious horizontal portion includes an outer edge and an inner end. A length between the outer edge and the inner end is equal to or greater than a distance between an outside surface of a wheel assembly and an outside edge of a blade of a mower.
