Water gardens are the greenest way to solve drainage issues. In fact, some cities will pay you to put a water garden in instead of connecting to the storm sewer.
Water gardens are basically an eight inch depression in the ground, usually in the lowest part of your yard. We dig the depression in a natural shape that fits your property. Then inside that depression we plant only plants that like water around their feet. We also pick plants that bloom at different times of the year, so we can keep color in the garden through three seasons. Then we use natural stone to line the edge and accent the garden.
