Ep. 260 Managing Stormwater with Rain Gardens | #GoodGrowing

Rain gardens are one of the most effective tools homeowners can use to manage stormwater, reduce runoff, and add beauty to the landscape. In this episode of the Good Growing Podcast, Chris, Emily, and Ken explore how rain gardens work, why they matter, and how they can help keep excess water out of storm sewers and local waterways.

Plus, hear about upcoming rain garden educational programs and community installation projects happening across Illinois Extension.
