ABSTRACT:
An improved container for growing a plant intended to be transplanted is provided. In one embodiment, the sidewall of the container includes an outer sidewall portion and at least one inset sidewall portion. The outer sidewall portion has a plurality of upwardly facing internal ledges positioned in spaced relationship one above the other. Each internal ledge serves to direct laterally growing roots to grow along the internal ledges. The inset sidewall portions of the sidewall are connected to and displaced inwardly from the outer sidewall portion, defining a plurality of root-pruning openings between the inset sidewall portion and the outer sidewall portion. Each root-pruning opening is aligned with an internal ledge so that roots growing along the internal ledges are directed to the root-pruning openings for air-root pruning. In an alternative embodiment, the sidewall of the container comprises a plurality of connected, rectangular sidewall sections disposed one above the other. Each rectangular sidewall section is greater in one dimension than the rectangular sidewall section below it, forming overhangs which are disposed opposite one another. The sidewall further comprises, a plurality of upwardly facing internal ledges connected between successive rectangular sidewall sections. Each internal ledge is disposed in an overhang and defines a plurality of root-pruning openings near the corners of the rectangular sidewall sections so that roots growing laterally in the container grow along the internal ledges and are directed to the root-pruning openings for air-pruning.
