ABSTRACT:
Chip-like mulching material having a specific gravity greater than 1 is formed from various plastics. The surface of the chips is embossed with a design providing additional surface area, thereby facilitating the diffusion to the surrounding environment of fugitive active ingredients when the same are contained therein including, for example, animal repellents, insecticides, or odorants. In a preferred embodiment, the chips are made from thermoplastic material, embossed and colored to simulate bark chips from a tree.
