ABSTRACT:
A feeder tube and method for dispensing a selected compound to the roots of a specifically targeted plant. The feeder tube contains a tubular body having an open top end and an open bottom end. A plurality of perforations are formed through the tubular body that communicates with a central conduit. A penetration cap is provided that protrudes below the bottom end of the tubular body. The penetration cap has a pointed tip and a wide base that is wider than the tubular body. As the plant feeder tube is driven into the ground, the penetration cap advances into the ground and creates an opening in the ground that is wider than the tubular body. Consequently, dirt does not press against the perforations in the tubular body as it is driven below ground level.
