ABSTRACT:
An improved protective clamp for the root ball portion of a tree is disclosed. The clamp includes a plurality of arcuate plate members, each of which is provided with an outwardly extending foot portion at the lower end thereof. Raised re-inforcing ribs on the sides of each plate and a tie bar at the upper end thereof are additional features which provide a greatly improved protection for the root ball during removal of the tree from the ground, or when the tree is being transported, stored, or other-wise handled prior to planting, compared with the traditional "ball-burlapping".
