Growing of grasses

Claim 1

A method of producing a grass bearing lamina comprising a sheet of flexible plastic reticulate structure composed of a first set of strands of single filaments positioned transversely to a second set of strands of single filaments to form a rectangular mesh of about 1/4 inch directly in contact with a surface impermeable to penetration by plant roots, the form of the reticulate structure being such that when placed in direct contact with said surface, shallow spaces are present between said surface and at least one of said sets of strands, distributing over the surface of the reticulate structure a layer of rooting medium containing an adequate quantity of grass seed of the selected variety or varieties, and subjecting the lamina to correct conditions of light, heat and moisture to effect rapid germination whereby the conducting roots from each seed grow through the layer of rooting medium lying above the reticulate structure, through the meshes in the reticulate structure, so that the the root system so produced bonds the rooting medium and the reticulate structure into a coherent unit of flexible laminar structure having at one surface growing grass blades and at the other surface a root structure which will strike and grow into an earth surface on which the lamina is laid.

Claim 2

A method of producing a grass bearing lamina comprising a sheet of flexible plastic reticulate structure composed of a first set of strands of single filaments positioned transversely to a second set of strands of single filaments to form a rectangular mesh of about 1/4 inch directly in contact with a surface impermeable to penetration by plant roots, the form of the reticulate structure being such that when placed in direct contact with said surface, shallow spaces are present between said surface and at least one of said sets of strands, distributing over the surface of the reticulate structure a layer of rooting medium containing an adequate quantity of grass seed of the selected variety or varieties, and subjecting the lamina to correct conditions of light, heat and moisture to effect rapid germination whereby the conducting roots from each seed grow through the layer of rooting medium lying above the reticulate structure, through the meshes in the reticulate structure, so that the the root system so produced bonds the rooting medium and the reticulate structure into a coherent unit of flexible laminar structure having at one surface growing grass blades and at the other surface a root structure which will strike and grow into an earth surface on which the lamina is laid.

Claim 6

A method of producing a grass-bearing lamina comprising placing a layer of rooting medium containing an adequate quantity of grass seed of the selected variety or varieties in contact with a surface impermeable to penetration by plant roots, embedding a sheet of flexible plastic reticulate structure composed of a first set of strands of single filaments positioned transversely to a second set of strands of single filaments to form a rectangular mesh of about 1/4 inch and subjecting the lamina to correct conditions of light, Heat and moisture to effect rapid germination whereby the conducting roots from each seed grow through the layer of rooting medium and the meshes in the reticulate structure so that the root system so produced bonds the rooting medium and the reticulate structure into a coherent unit of flexible laminar structure having at one surface growing grass blades and at the other surface a root structure which will strike and grow into an earth surface on which the lamina is laid.

Claim 7

A method of producing a grass-bearing lamina comprising placing a layer of rooting medium containing an adequate quantity of grass seed of the selected variety or varieties in contact with a surface impermeable to penetration by plant roots, embedding a sheet of flexible plastic reticulate structure composed of a first set of strands of single filaments positioned transversely to a second set of strands of single filaments to form a rectangular mesh of about 1/4 inch and subjecting the lamina to correct conditions of light, Heat and moisture to effect rapid germination whereby the conducting roots from each seed grow through the layer of rooting medium and the meshes in the reticulate structure so that the root system so produced bonds the rooting medium and the reticulate structure into a coherent unit of flexible laminar structure having at one surface growing grass blades and at the other surface a root structure which will strike and grow into an earth surface on which the lamina is laid.
