ABSTRACT:
A frame for a garden bed collects and stores solar heat energy and transmits the energy to soil within a garden bed. Hollow frame members contain a heat storage medium such as water or a water antifreeze mixture. A variety of structures, including a clear plastic cover or a trellis, may be erected above the present frame. An electric immersion heat supplements solar heat energy to further warm the garden bed soil.
