Plant container for growing plants which are to be transplanted

Abstract

A plant container for growing plants to a stage suitable for transplanting. The plant container comprises a base having an imperforate upper surface with a rib upstanding from the upper center of the base and a removable sleeve arrangement that is disposed concentrically about the rib. The lower edge of the sleeve arrangement is disposed on or adjacent to the outer upper peripheral surface of the base to provide drainage openings therebetween. The sleeve arrangement is removable to permit the base and root mass and growing medium of the plant grown in the container and disposed about the rib to be transplanted as a unit. The rib functions to hold the root mass and growing medium of the plant on the base and to permit the container, absent the sleeve, to be handled with a minimum loss of growing medium in normal handling and transplanting operations. In one preferred embodiment, the underside of the base is provided with a depending nose section having a ground penetrating configuration for injection planting of the container absent the sleeve. In another preferred embodiment, a plurality of integrally interconnected bases are provided in an array of rows and ranks to provide a plurality of integrally interconnected containers for the initial growing of plants in the containers in a greenhouse.
