Abstract: A container for seedlings to be grown by the air root pruning method is moulded as a flat plastic blank with walls hinged for folding and base hinged to one of the walls permitting the container to be erected by engaging the walls and the base and attaching one wall to another. The erected containers stand in a tray like carrier and are connected together by a tie which overlies the containers. A handle extends through the tie to engage the carrier allowing a group of containers to be handled.

Abstract: A panel (10) for use as a side wall of a plant growth container is disclosed. In one embodiment the panel (10) comprises an elongate cuspated sheet (11) having apertures formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant grown within the container. The sheet (11) includes a non-cuspated edge section (12), the non-cuspated edge section (12) being co-operable with a complementary edge section (13) of the same sheet (11) or of an adjacent sheet. The co-operable edge sections (12, 13) form a guideway for holding means (32), the holding means (32) passing along the guideway releasably hold the edge sections (12, 13) in use form a side wall of the container. A plant growth container having at least one panel (10) as described is also disclosed.
