The August 29, 2026 Westerville Library Sustainability Fair was a rousing success to end the month on a high note. Delaware and Franklin County Master Gardener Volunteers (MGVs) were respresented at the Sustainability Expo session. The MGVs were in good company with other tables representing Dawes Arboretum, Audubon Columbus, Soil and Water Conservation Service, Franklin Park Conservatory, Sustainable Westerville, SWACO and electric appliance/car and solar power consortium advisors.
A constant flow of interested attendees of all ages passed through to learn at MGVs' two tables full of informational posters, materials, and plant examples focusing on the importance of native species. The Expo participants were excellent partners for referrals and providing supporting resources. A number of attendees were interested in learning more about the Master Gardener program and were appreciative of followup contact information. Each MGV table visitor was provided an educational overview of the importance and co-reliance of native species throughout the spectrum of plants, insects and bugs, birds, and mammals. Supplementary Ohio Department of Natural Resource field guides and College of Food Agriculture and Environmental Sciences (CFAES) handouts were made available for further study. Master Gardeners were well prepared and equipped to provide answers to questions and direction for tracking down further information through OSU Extension.

August was an especially fun month for both our TH team and the residents at The Avalon of Lewis Center and Willowbrook Christian Village. We always try to incorporate a dried flower activity toward the end of the summer. This year it was potpourri. Everyone handled drying at least one of the ingredients from our two potpourri recipes. We used a few different methods including air drying by hanging upside down, drying flat on a well-ventilated surface, as well as dehydrating fruit using an oven or dehydrator.
We used a few different methods including air drying by hanging upside down, drying flat on a well-ventilated surface, as well as dehydrating fruit using an oven or dehydrator. The residents were able to chose which potpourri they wanted to make…. dried marigold, lemon balm, dried oranges/ lemons and lemon essential oil or dried lavender, sage, mint, lambs' ear, and lavender essential oil.
Our friends thoroughly enjoyed this hands-on activity...smelling the herbs, flowers and lavender and creating their own individual jars of potpourri. The display looked like a kaleidoscope of colors! Each jar had a label attached reminding them to shake daily, keep the lid on for 3 weeks, open and enjoy! We were thrilled it was such a success and a terrific way to repurpose oui yogurt jars!
Some of our WillowBrook team attended an appreciation volunteer open house earlier in the month and had a wonderful time. We finished the month with a TH appreciation gathering and brainstorming meeting and welcomed 2 new interns to our team… Pat Hollingsworth and Deb D’Aurora!
