On two consecutive Saturdays, September 19th and 26th, a group of energetic NCGC members cut down several patches of Japanese knotweed, opposite the goat pen in Irwin Park. Armed with clippers, horticultural vinegar and black coffee, they cut and bagged the branches, and then poured vinegar and coffee in the hollow stalks. Hopefully, this will weaken the roots of the invasive knotweed plants at the time when they are the weakest (producing seeds). This action is part of a 3-year project to find the safest way to eradicate invasives from Irwin Park and encourage more native pollinators to return.
