On the second day, they build two rectangular redwood frames for the gates, add a diagonal board for support and attach heavy-duty hinges. The gates are constructed of overlapping slats, within the frame, to match the existing wood fence (figure D).The living wall is constructed like a sandwich, with two sheets of wire as the bread and soil in between. This unique wall will add interest and color to the yard. Unlike an ordinary redwood fence, though, this wall will house fragrant pockets of flowers that will attract butterflies and hummingbirds. The cost of a living wall is about the same as a fence.
The galvanized wire mesh is rolled out on a tarp on the ground and cut to the size of the wall. The mesh is spray-painted brown for camouflage. Shredded redwood mulch and wet sphagnum moss are spread on top of the mesh, followed by sod. Ahmed doesn't use sod for the grass but rather for the sheet of soil underneath. The grass side goes on the interior of the living wall. They use zip ties to attach the sod to the wire.
The living wall is attached to the front of the posts, and another sheet of wire mesh goes on the back. More sod and soil are stuffed between the two sheets of mesh. Irrigation lines run through the soil to keep the plants moist. The wire at the top of the living wall is bent inward to contain the soil and will be camouflaged with plants.
Ahmad has chosen a variety of plants for the living wall; ground covers and succulents work especially well. For the side yard, he chooses taller plants for the back, along the fence, and low-growing plants for in front. He plants white potato vines, which grow very fast, to climb the fence.
