Abstract
A plant container has a base and a sidewall upwardly extending from the base. The sidewall includes stepped sidewall sections that each include a plurality of generally vertical sidewall panels having successively larger cross-sectional dimensions with distance from the base and horizontal ledges extending between an upper edge of an adjacent lower one of the sidewall panels and a lower edge of an adjacent upper one of the sidewall panels. The sidewall further includes a plurality of ribs, where each rib is formed between two of the stepped sidewall sections and extends inwardly across the ledges of the two stepped sidewall sections. Each rib has two legs that extend apart to form an outwardly-directed open channel. Holes are formed in the sidewall for air root pruning, where each hole is formed directly between a ledge and a leg of one of the ribs.
