Abstract: A post hole digger and a method of implanting a post in the ground. A boring implement having a piercing free end and also having an attachment flange is secured to an end portion of a post to be implanted in the ground. The implement has a tapered body section with a projecting serrated edge on opposed sides thereof. The serrated edges extend angularly from a common longitudinal plane and in opposed angular directions. A pipe section is secured to the implement and a garden hose is connected thereto whereby to direct a stream of water in the direction of said piercing free end whereby axial rotation and counter-rotation of said post causes the implement to bore into the ground to cause said post to descend in a bore hole. After the post is implanted the garden hose is disconnected from the pipe section by applying a pulling force on the hose.
