<p>A horticultural ground cover for gardens or any other area where it is desired to prevent the growth of undesirable vegetation but promote the growth of desirable vegetation. A horticultural ground sheet comprises a flexible sheet of opaque material, for example black polyethylene film, interspersed with a plurality of slits. These slits must prevent as much as possible the entry of undesirable plant seeds but permit the entry of air and water to allow the desired plants to grow. The ground cover prevents the growth of plant shoots beneath it. Openings are formed to allow desired vegetation to grow.</p> |
