A rain garden is not your typical garden but rather a kind of “Superhero” garden. To all the gardeners that may be shocked by my claim, please allow me to explain myself. Rain gardens are composed of native shrubs, perennials, and flowers that are planted on a small depression on a slope. These superhero gardens are beneficial to us and wildlife in many ways. The main tasks of these gardens are to temporarily capture and soak rainwater runoff that flows from roofs, lawns, and driveways. If you’re thinking” but all gardens do that!” the answer is: yes and no. The reason is that traditional gardens are not planted in a “bowl-shaped” area but planted in a flat area. On this flat area, some water filters into the soil but MOST of the water runs off until it reaches a lake, river, stream, or storm water drain. During its journey, runoff picks up pollutants such as fertilizers, pesticides, bacteria, dirt, oil, garbage, etc. Those pollutants will eventually reach and negatively affect our sources of drinking water and recreational areas. But with the help of our Superhero- Rain Garden the water will be captured and filter most of the pollutants. By collecting water in the “bowl-shaped” area, rain gardens also protect against flooding and erosion by minimizing the surge of water that rushes to a body of water after a storm. You can plant native plants that are accustomed to excess water in your rain garden. The added benefit of planting native is that these plants will help attract native species and reduce the amount of time spent in maintaining your garden. If you are trying to save the bees, butterflies and other friends the Superhero- Rain Garden will save them all along with enhancing the quality of our drinking water.
We have an upcoming volunteer opportunity to participate in planting a rain garden- Let’s Create a Superhero with Keep Durham Beautiful- Rain Garden Planting at Watts Montessori Elementary School on October 9, 2016 from 2:00 pm- 5:00pm.
