Invasive Plant Removal

Invasive plants and vines are a serious problem in Connecticut and throughout the world because they out-compete, displace, or kill other species. Many were introduced accidentally or intentionally for garden use and thrive and proliferate.

For example, Oriental Bittersweet (Celastrus orbiculatus), and Porcelainberry (Ampelopsis brevipedunculata) are vigorously growing vines that smother and kill other vegetation.

Japanese Knotweed

Japanese Knotweed (Polygonum cuspidatum), also known as Godzilla weed, is found along roadsides and stream banks, reaching up to 10’ in height. It is extremely hard to eradicate because it reproduces by both rhizomes and seeds and cutting back only strengthens the invaders.

Invasive vines

GG&C always seeks volunteer assistance in removing or at least slowing the growth of invasives. We explain the problems to many student groups as well as adults who then get to work either digging and pulling up or cutting down many of these aggressive plants.
