Abstract: A divot retainer (1) has a flat rectangular divot retaining head (2) and a ground-penetrating stem (3) which is cross-shaped in plan. The retainer (1) is of a starch/plasticizer/water composition which is injection molded. It is stored until use in an air-tight package (10) and it is hydrophilic whereby it degrades upon contact with moisture. In appearance and mechanical strength it is plastics-like and degrades under the same conditions as is required by the divot knits back into the ground.
