Abstract: A method of supporting vegetation in a multilayer vegetation support system on a roof, the method includes disposing a reservoir substrate on the roof. The reservoir substrate also includes a plurality of concave dimples separated by land areas. The method further includes disposing a composite on the reservoir substrate to overlay the plurality of dimples and forms a corresponding number of chambers defined by the reservoir structure and the composite, the composite having a root barrier layer and a multitude of projecting loops, the loops being interconnected at a multitude of locations spaced from the root barrier layer.

Abstract: A multilayer vegetation support system is provided, wherein the system includes a reservoir substrate and an overlying composite, wherein a growing medium and vegetation are disposed on an exposed surface of the composite. The reservoir substrate is a generally planar member having a plurality of recesses or dimples, and can include a plurality of drain apertures in land areas intermediate the dimples. The composite includes a water retention layer, a root barrier layer and a multitude of projecting loops, wherein a growing medium and vegetation overlie and intertwine with the projecting loops.

Abstract: A panel assembly includes a plurality of open faced cells fluidly interconnected for retaining a growing medium and live vegetation in a vertical orientation of the panel assembly. The fluid interconnection of the cells provides for gravitationally induced water transfer from the growing medium of a first cell to the growing medium of a second cell, as well as root growth between the cells.
