ABSTRACT:
An apparatus and method for removing unwanted vegetation (46). A fork (12) is provided having a vibratory motor (38) attached thereto. The fork is inserted into the rooting medium (48) surrounding the root mass (50) of the vegetation. While the fork is inserted therein, the fork is vibrated near the thixotropic level of the rooting medium, causing the rooting medium to liquefy. When the rooting medium is liquefied, the fork is raised upwardly, lifting the vegetation and corresponding root mass free of the rooting medium.
