Workshops and Events


Year after year, expert speakers in our popular Third Saturday Series draw an audience from miles away. Participants leave with knowledge they can use in their own gardens, yards and homes. Many events include demonstrations. The Hamilton College campus has been designated as an arboretum; please consider time to explore if you attend one of our events.

All events are free and open to the public and everyone interested in gardens and landscapes is encouraged to attend. Pre-registration is not required. We encourage membership in the Arboretum as it helps support the programs offered throughout the year. Members are also invited to two special members-only events held in May and July. Membership forms are available at the event sign-in or online.

All events begin promptly at 10 a.m. and end at noon. Events are held in the Taylor Science Center, GO27, Kennedy Auditorium, unless otherwise noted. Parking is available near the building. Directions & campus maps >>
