An apparatus and method of root pruning a woody plant having a main trunk and usually a distinct crown, such as a tree. More particularly, the invention relates to an apparatus and manner in which to prune root systems of trees, in preparation of transplantation or while excavating in proximity to a tree, more efficiently and effectively than in the past. The invention includes among its essential elements a vibratory apparatus coupled to a mobile device. The mobile device may be an excavator machine having an articulated machine arm with the root pruning vibratory apparatus attached thereto. The machine's articulated arm positions the vibratory apparatus in a desired location while applying force to the apparatus, pushing it into the ground while the apparatus is vibrating, penetrating the blade into the ground or, optionally, the vibratory apparatus having the ability to provide a hammering action. The vibratory apparatus has at least a lower member and an upper member, the lower member capable of vibrating and the upper member adapted to be removably attached to the mobile device. The vibratory lower member is capable of accepting a blade mounting member. The blade mounting member is adapted for ground penetration when placed in contact with the ground, capable of cutting cleanly through tree roots during ground penetration.
