An adjustable planter disk comprised of a circular disk constructed of a single resin composite sheet is disclosed. The sheet has a first terminating end that overlaps, or partially overlaps, a second terminating end. The sheet includes a peripheral edge and center hole. The first terminating end rotates overtop the second terminating end and latches thereto using a pair of hooks on the first terminating end and a series of corresponding holes on the second terminating end to create differing radii. The sheet is divided into a plurality of sectors, each sector including a living hinge that runs from the peripheral edge to the center that allows for the first terminating end to extend and contract. Additionally, along the peripheral edge of the circular are a plurality of water drainage holes.
