An accessory support system includes a mounting plate, a deck support, and a mounting member. The mounting plate includes a tree facing side and an upper axial end in substantially perpendicular orientation relative to the tree facing side. The deck support is coupled to the mounting plate. The deck support includes a frame extending outwardly from the mounting plate and away from the tree facing side along a direction that is substantially parallel to the upper axial end. The frame defines a plurality of openings arranged along a perimeter of the frame and a central opening that is larger than the plurality of openings. The mounting member is configured to couple at least one of the mounting plate or the deck support to a tree.
