A rain garden is a garden designed to temporarily hold and absorb rainwater and snowmelt run-off that flows from roofs, driveways, patios and lawns.
Rain gardens remove up to 90% of nutrients and chemicals and up to 80% of sediments from runoff. Compared to a conventional lawn, rain gardens allow for 30-40% more water to soak into the ground.
A rain garden is not a water garden, pond or wetland. It only holds water during and following rainfall or snow melt. And because it drains within 12-48 hours, it prevents the breeding of mosquitoes.
Rain gardens also help make neighbourhoods cleaner and more beautiful, and provide habitat for pollinators.
