A rain garden is a plant bed that collects rain runoff from your roof, driveway, patio, or other waterproof outdoor surface. A pipe connected to a downspout or an above-ground channel conveys the water to the garden. In a rain garden, the excess water is absorbed quickly into the soil.
A rain garden is built in a shallow depression, usually about six to eight inches deep. The slight depression allows the garden to hold water for a short period of time while it is absorbed into the soil. The down-slope side of a garden built on an incline will also have a low earthen berm to help the garden hold the collected water for less than twenty-four hours.
