Auburn-based EarthPlanter makes commercial self-watering planters designed to keep streetscapes, campuses, and other public spaces planted with less watering and maintenance. Now a division of Bo-Mer Custom Manufacturing, the business was acquired in 2010 and operates from a 35,000-square-foot facility, with more than 200,000 planters installed across North America. Its U.S.-made planters carry a lifetime warranty, and the company’s reservoir-and-wicking design can reduce water and labor use by 50% to 80%.
