  • Patent number: 8056646
    Abstract: A device for making holes in the ground for easy insertion and planting of garden plants which are rooted in small containers. The tool has a least one frustro-conical or frustro-pyramidal shaped projection forming a cone extending down projecting downward from a base of a stirrup having a means for attaching a handle defining a cylinder formed at the top of the stirrup. A long handle may project up from the tool body with a large aperture just above the tool body into which the user's foot may be placed to help in pushing the projections into the ground to make holes sized for planting garden plants. The tool body can be connected to the handle rigidly or may swivel if desired. In one embodiment a plurality of frustro-conical shaped projections extend from a tool body. The projections are assembled onto a tool body in such a way that the distance between each of the projections is easy adjustable.
