Abstract: A soil guard wall assembly includes a plurality of elongated soil guard wall modules each of which has a hexagonal configuration in section and is coupled together with each other so as to form the soil guard wall assembly with a honeycomb shape.

Abstract: A honeycomb grass planting unit includes a hexagonal body with six peripheral walls extending vertically and including a plurality of soilpots and a central fence therein. The soilpots are interconnected by plates to reinforce the structure. Holes are formed in the soilpots and the fence through which hoses pass. Two receiving sockets are disposed on diagonal apexes of the hexagonal body and are releasably engaged with four snapping fasteners disposed on the remaining apexes of another hexagonal body to provide a releasable interconnection between two honeycomb grassplanting units.
