A pan-like shaped device with at least one opening in the bottom to accommodate a plant stem or trunk, having at least one aperture in the bottom to permit water to escape to the plant roots and interlocking peripheral walls extending upward from the perimeter of the bottom of the device so the device can be easily connected with like devices having interlocking peripheral walls to expand the area encompassed by the devices. When placed around a growing plant, the horticulture device provides a basin for directing water to the roots of a plant, helps to control weeds because it acts as a weed barrier, and retains moisture around the root by slowing evaporation. The horticulture device can be made in various sizes and shapes to accommodate various kinds of plants and ground areas and various connectors can secure multiple devices together to cover a greater ground area.
