Abstract

Abstract A novel method is proposed for growing ground covers as sods. Advantage is taken of the growth habits of these types of plants to grow and expand laterally by planting them in permanent row/hill nurseries between which is placed plastic sheeting covered with an appropriate growing medium. The row/hill nurseries grow laterally into these areas and knit the growing medium into a sod which is harvested by cutting along the edge of the plastic sheeting. The latter may be harvested with the sod to protect it in shipment or left behind in place, covered with more growing medium, and the process repeated. The method, in comparison to the conventional method of planting ground covers by rooted cuttings one at a time, requires less labor to install, provides instant weed-free cover complete with mulch, and requires less watering and initial care.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 94 words
A method for producing ground cover sods, comprising establishing parallel spaced row/hill nurseries of ground cover plants which spread laterally by stolons, rhizomes, runners, or tillers, placing plastic sheeting or film on the ground in the spaces between said nurseries, covering said sheeting or film with a growing medium enabling rooting therein by the lateral growth from said nurseries, which growth becomes matted to form a sod, harvesting said sod by cutting off said growth in lines along both edges of the plastic film or sheeting, and removing said sod from between said nurseries.
Claim 2
Independent Claim 94 words
A method for producing ground cover sods, comprising establishing parallel spaced row/hill nurseries of ground cover plants which spread laterally by stolons, rhizomes, runners, or tillers, placing plastic sheeting or film on the ground in the spaces between said nurseries, covering said sheeting or film with a growing medium enabling rooting therein by the lateral growth from said nurseries, which growth becomes matted to form a sod, harvesting said sod by cutting off said growth in lines along both edges of the plastic film or sheeting, and removing said sod from between said nurseries.
Claim 3
Dependent Claim 27 words
A method as in claim 1, wherein the film or sheeting has perforations therein, which perforations are of a size to permit drainage but prevent root penetration.
Claim 4
Dependent Claim 18 words
A method as in claim 1, wherein a netting lies in, above, or immediately below said growing medium.
Claim 5
Dependent Claim 39 words
A method as in claim 1, wherein after said harvest of sod, plastic sheeting or film is again placed between said nurseries, a growing medium is placed thereon, and, when sod is again formed, said sod is again harvested.
