Abstract: In order to reduce labor costs, enhance handling convenience, and encourage resource reutilization, a reusable tree-shrub carrier is disclosed. The carrier includes a plurality of side wall sections each configured so as to be arranged into a root ball container. Each of the side wall sections is substantially identical in shape and has an edge to be placed in juxtaposition to an edge of an adjacent one of the side wall sections such that the container has at least one open end. the carrier also includes a plurality of corner locking channels for releasably securing the edges of the side wall sections and retention strap assemblies for releasably securing a root ball during carrier transport.
