For those interested in rain gardens, a new University of Nebraska-Lincoln Extension online publication can help. It offers information about the benefits and how to choose the size and site, with many features, videos and charts.
A rain garden is a garden positioned so it can collect rainwater and runoff, preventing that water from reaching storm drains.
Rain gardens also filter out pollutants from rainwater, and their ability to capture water enhances soil moisture and reduces runoff volumes.
Information is included about how to measure a hill slope, a roof and the rate that the soil absorbs water.
These factors are important to consider when building a rain garden.
The captured water can also enhance garden plant health and potentially reduce the need to irrigate plants.
The publication can be found at: http://www.ianrpubs.unl.edu/epublic/live/ec1262/build/ec1262.pdf.
