ABSTRACT:
A vertical air-root-pruning container involving a series of vertical offsets or air gaps displaced around the sidewall of a container. The offsets or air gaps are alternately displaced outwardly or inwardly to air-prune spiral root growth in both right and left directions. Such a container inhibits spiral growth, promotes root branching, and results in more even root distribution as well as increased root growth in the growing medium.
