Measuring a little bit bigger than 3 feet square (37.37 inches square, to be exact), this waterproof tarp has snaps on each corner, allowing you to create a raised edge that will help keep messes contained. When you’re done with your gardening projects, just unsnap a side and shake out any excess soil and other debris, either outside or over a trash can. After unsnapping the rest of the sides, wipe the mat clean and dry, then fold it up for easy storage. Ready to get started on your gardening and want an easy way to clean up afterwards? Shop the ZZ Lighting Indoor Repotting Tidy Square Mat for just $11, and you’ll be set.
