Abstract
An air-root-pruning container for growing a plant and a unitary flat including a plurality of the containers. The air-root-pruning container includes a base and a sidewall upwardly extending from the base. The sidewall includes inwardly projecting ribs, each rib extending in an upward direction along the sidewall, and each rib having a first side and a second side. The sidewall further includes ledges extending from the first side of each rib, ledges extending from the second side of each rib, and holes through the sidewall, each hole being positioned adjacent a location where one of the ledges extends from one of the ribs. For each rib, each of the ledges extending from the first side of the rib extend from the rib at a location that is vertically offset from a location where each of the ledges extending from the second side of the rib extend from the rib.
