The Gardeners of the Bluffton/Pandora Area will host a public lecture on rain gardens from 6:30 to 8 p.m., Tuesday, April 10, in the lower level meeting room of the Bluffton Public Library.

Tim Brugeman, president of the Blanchard River Watershed Partnership, is the speaker.

The Watershed Partnership is focusing much of itefforts this year on the Riley Creak Watershed Action Plan. Brugeman will talk about rain gardens, which are built in a natural or man-made depression that is designed to temporarily fill with rain water from downspouts, driveways, or streets.

Rain gardens allow the water to soak back into the ground and filter pollutants with the help of deep-rooted native plants.

The rain gardens can vary in shape and size and may include formally arranged plants, fields of wildflowers, shrubs, stone culverts and paths, and other landscape features.

The meeting is open to the public with no admission charge.
