  • Patent number: 7497173
    Abstract: A seed placement device (10) that is comprised of a seeding strip (12) and a boring tool (32). The seeding strip (12) has a multiplicity of equidistant holes (26) extending therethrough, and the boring tool (32) has an upper end (34), a shank (36) and a lower end (38) that terminates in a point (40). The seed placement device (10) is designed to quickly and easily allow a person to place a multiplicity of seeds (90) in the ground (92). Once the seeding strip (12) is placed in a desired location on the ground (92), a person inserts the boring tool (32) through each of the holes (26) and into the ground (92), thus creating a series of equidistant cavities (94), into each of which at least one seed (90) can be placed.
