An EarthWall is essentially a vertical set of trays which can be filled with growing material and planted. Although the tray system initially looks like a set of horizontal galvanized metal fence rails, after plants or ground cover takes root, the planting trays become grown over and the galvanized railings are hidden from view. If need be, the galvanized side can be painted or covered with wood to temporarily obscure the galvanized material from view.
