The sifting implement includes a frame having an opening through which compost, dirt, rocks, sand, or other material is sifted. A primary screen is supported in the opening to catch larger items in the material being sifted. Other screens are used for separating different size materials. A bracket is attached to the implement and engages an edge of the container, which allows the implement to be tilted in order to dump the larger items.
