On Tuesday, July 6, from 1 to 3 p.m., Holly Bellebuono of Vineyard Herbs returns to the Polly Hill Arboretum for her popular salve-making workshop.

This fun, hands-on workshop starts with a walk to identify and collect medicinal herbs and weeds on the arboretum grounds. Next, participants make their own oil infusions and beeswax-based ointments.

Learn practical knowledge on when and how to use herbal salves and take home your useful creations. Supplies included. Please preregister. The cost is $45; $40 for arboretum members.
