The Hopkinton Garden Club’s Speaker Series continues on Tuesday, Oct. 18, at 7:30 p.m. with a presentation from Gretel Anspach on pruning basics. Attendees will learn about the science behind when, how and why to prune woody plants, and be able to determine which plants can be pruned by a home gardener and which require the services of a professional. The event will be held live at the HCAM studios (77 Main Street) and can be viewed on Zoom. It is free and open to the public.
