Our Living Sustainably Series - Session 2

We strive to create a sustainable environment but there seems to be a lot of big issues out of our control as individuals. What can we do? Where can we start? Let's start with your own backyard and your home environment! You have control and you can make a difference!

Join us on June 11 @ 7PM, Radnor Lake State Park Visitors Center, for a presentation about Sustainable Gardening & Landscaping featuring guest speakers from WildOnes and Master Gardeners. Find out how you can make your own home and yard a more sustainable environment.

Social gathering with refreshments begins at 6:30. 

Register here for updates. 

And yes! the pre-program hike around Radnor Lake is back!
