A planter assembly to raise a garden bed to a height that eliminates or minimizes stoop labour is comprised of flexible materials with latent rigidity as well as a rigid element. Flexible wire mesh is formed into a perimeter frame of pre-determined width, length and height in combination with rods and wire. Rods used as corner posts on the outside of the wire mesh hold the mesh taut. Rods are also used as braces for these corner posts. And they are used as clamping rods on the inside corners of the mesh to hold it to the corner posts. Wire is used to tie the inner and outer rods and for other attachments. Other rods are interlaced vertically through the horizontal wires of the mesh. These rods are placed so that they push the bottom horizontal wire down, the top horizontal wire up, and increase the distance the other horizontal mesh wires travel between fixed corner posts. In this way, the rigidity of the perimeter frame is increased. A textile with adequate vertical and horizontal tensile strength lines the perimeter frame, providing a barrier impervious to soil. The textile encloses the top horizontal wire of the mesh within a hem held fast by wire and is thereby restrained. A band of the textile, sufficiently wide to be held to the ground by the placement of soil, extends from the base of the perimeter frame towards its middle. Wire is also used as crossties to hold opposite side walls straight and upright. Crossties enable the lateral earth pressure pushing against one side to resist the lateral earth pressure pushing against the side opposite.
