If you asked me a year ago what a rain garden was I would not have been able to explain it correctly. I believed one of the many misconceptions, that rain gardens are filled with water. A properly designed rain garden infiltrates the water into the ground within 24 hours. That is their primary purpose, absorb water. The majority of the time, the rain garden is bone dry. They do not breed mosquitoes, again because water does not pool long enough to hatch their eggs. They are low maintenance if you take the time in the spring and fall to tend to them. All these myths keep homeowners from solving their water problems with an aesthetic and effective system.
