The Garden Angel™ watering device is a polymer unit (food-grade plastic) designed to capture, direct, and contain moisture in a plant's root system. The units are designed for use in commercial and residential gardening purposes and can be installed in the ground, around existing plants/trees/shrubs, or in group or individual self-contained units. The Garden Angel™ watering device not only provides a better growing environment, but also requires less water and weeding than conventional planting! In May of 2014, 2 hand-crafted prototype units were created incorporating the single hole, 4 spike design.
