A pot for nursery plants having opposed walls joined along their edges with margins of the walls having a series of openings to promote air-pruning of the plant roots. The wall edges may be joined to one another by various means including fusing, adhesives, taping or the pot may be a molded structure. A rack is disclosed having receptacles of appropriate shape to receive a multitude of pots of similar external shape for pot support in a snug manner. A modified form of the pot includes three wall members each having a series of edge located openings. The walls are joined along their edges with each wall member having legs to provide a free-standing pot.
