The Mushroom Festival is an all-volunteer event. Without our volunteers we could not have this spectacular weekend in Kennett Square. Mushroom Festival volunteers are at the core of our success. This year’s needs were just posted on Sign-Up Genius. Learn more at our Become a Volunteer page which highlights opportunities for individuals and organizations. Enjoy the Mushroom Festival in a new way — Volunteer for a half-day, all day, or even the entire weekend. Become part of the Mushroom Festival family. Free volunteer t-shirts and parking passes are given to all volunteers!
