Abstract
A planting hole forming apparatus includes a central shaft having a longitudinal axis, a bottom leading end and an upper trailing end, and a discontinuous flighting comprising a plurality of flighting sections spiraling around the central shaft at spaced locations along the shaft adjacent the bottom leading end. Some form of drive mechanism, for example a hand-held drill, is used to rotate the central shaft about its longitudinal axis to thereby form the planting hole. The drive mechanism is chosen to accommodate the size of the central shaft and to supply the necessary torque to rotate the central shaft sufficiently to form the planting hole. The structure of the flighting sections is such that while the planting hole is being formed the soil is simultaneously pulverized with a substantial portion of the pulverized soil being left in the hole.
