Saturday Speaker Series

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

All events in this series begin at 10 a.m. and are free and open to the public. 

We encourage membership in the Arboretum as it helps support the programs offered throughout the year. Membership forms are available at the event sign-in or online.

NOTE:  Individuals must be vaccinated and wear a mask to attend indoor events on campus at this time. Due to changing COVID concerns, the decision about whether an event speaker will be on-campus or only via Zoom will be made close to the event date. On-campus speakers will also be available on Zoom. https://hamilton.zoom.us/j/92317875511.

Please check the website prior to each event for its on-campus status.

With a PhD in forest management from Virginia Tech, Jim will discuss his research interest in using non-timber forest products (NTFPs) and the sustainable management of forest resources.
