Abstract

The trays can be preplanted and installed with the plants already growing in the trays. Alternatively, the trays can be positioned as components of the green roof system, filled with plant growing medium, and planted following their installation. Desirably the trays are substantially rectangular with adjacent corners of adjacent trays interconnected when on the roof structure. Pieces of carpet cut in various shapes can be used to form the respective trays.
