• Construct the box for the raised garden beds: Screw the frames together by putting screws through the cleats on the inner corners. Make sure the frames’ “display” sides are facing outward.
• Trim the metal: Initially, put on some gloves—those metal edges can be razor-sharp! The panels should next be trimmed to length with metal cutters.
• Put the metal in place: Fasten the metal panels to the frames with screws, 8 to 10 inches apart along the upper and bottom sides. Drill a screw every second column along the side margins.
• Incorporate plywood support to the metal raised garden beds: Screw plywood over light-gauge galvanized or corrugated metal to reinforce it.
