Abstract: Brackets for engaging frame members of a raised garden bed have a plurality of sockets, for example, a larger socket and a smaller socket, for engaging one end of alternative supports of different diameters. The brackets are made of substantially rigid material and the alternative supports are adapted to alternative coverings of different materials for extending the growing season of plants planted within the frame of the garden bed. Brackets may either be simple straight brackets for fastening on the outside of a straight member of the frame, corner brackets having an L-shaped angle at one end, or J-shaped brackets for engaging over the top of a frame member.

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.
