Rain Gardens are one way to create a beautiful garden spot that serves a very functional purpose. Drain spouts and roof gutters can create areas around the foundation of a building that begin to erode or create washout pathways that create water problems inside. Rain Gardens can absorb and filtrate 30% more water from rainfall draining from the roof.

A well-constructed Rain Garden is simple to construct and to maintain. It help decrease mosquito breeding and other pest insects while creating a natural habitat for birds and butterflies. Rain Gardens can also enhance sidewalk appeal and decrease areas of flooding.

Rain Gardens are best suited for saucer-shaped landscape depressions and area located at least 10 feet downhill from a building in soil that is at least 24 inches deep. Any slope should be less than a 12% decline. It is also important that the Garden avoid being built over utilities, septic systems or an under any existing trees.

The size of a Rain Garden depends on the amount of water it needs to absorb from the roofline or problem area. Generally, for a downspout, a Garden should be about 4-8 feet across and 5-10% the size of the roof area that drains to the downspout.

The types of plants that work best for the Garden are native one to the area. These will be most tolerant of both local weather and soil conditions and will attract native birds and butterflies. A Nursery can help you find the right plants for the amount of sun exposure. The plants you select should be perennials (those that return year after year) and you can brighten the garden with annuals or seasonal plants placed around or in the dry margins of the Rain Garden.
