On 26 October 2025 from 1:00 to 3 pm, Tom Hoagland, President, Friends of Canonchet, and Alan Woodmansee, Master Gardener, will lead a guided trail walk in Canonchet Farm, a 124 acre second growth woodland that has become infested with invasive plants, shrubs and vines.

These plants are increasingly popping up in home gardens and natural landscapes due to their prevalence in South County.  Birds spread the seeds.

Learn how to identify and control common invasive plants, such as knotweed, porcelain berry, bittersweet, multiflora rose and privet. The trail is easy but does have protruding roots and can sometimes be wet. Appropriate footwear should be worn.
