Are rain gardens appropriate? |

Often runoff can be diverted to localized low
spots in your yard. These areas, when planted with water-tolerant vegetation
such as redbuds, st. john's wort, cherrybark oak, and sweet pepperbush, are
called rain gardens. Rain gardens naturally filter water and provide an
effective means for putting surface water back into groundwater. Rain
gardens without designed underdrain systems work best in sandy soils, so
their use is most appropriate in the coastal plain and sandhills of North
Carolina. They can be engineered by adding an underdrain, however, to be
used in the piedmont and mountains as well.
