Abstract: A support frame is provided for supporting a lawn bag on the gound with its mouth open to receive leaves raked into the bag. The frame components include a flexible clip member having a longitudinal slot defined in one face of the clip. A flexible rod is adapted for press-fit engagement within the longitudinal slot of the flexible clip with a portion of the perimeter of a lawn bag trapped between the clip and the rod. The flexible rod has a length greater than the length of the flexible clip so that a portion of the rod overhangs from each end of the flexible clip. These overhang portions of the flexible rod are adapted to be pushed into the ground to support the frame, as well as the lawn bag. The clip and rod are sufficiently flexible to be bent into a U-shape while maintaining the mouth of the trash lawn bag open. In another aspect of the invention, a support block is provided which allows the support frame to be mounted to a vertical wall to support the plastic bag in a vertical orientation.
