Isabelle Martineau, a Montreal‑based entrepreneur, began removing Japanese knotweed in the community of Abercorn, Quebec, on the morning of Saturday, 22 August 2026. The plant is being harvested and processed into lemonade as part of her effort to reduce the spread of the invasive species.
Japanese knotweed is a non‑native, fast‑spreading plant that can damage natural ecosystems and infrastructure. Provincial authorities in Quebec have identified the weed as a threat and are urging residents and businesses to take part in removal campaigns.
Martineau’s approach involves collecting the knotweed from affected sites, then subjecting the material to a processing method that yields a beverage. The resulting lemonade is made from the harvested plant, turning what is typically considered waste into a consumable product.
The initiative aligns with the province’s call for active removal of knotweed. By providing a commercial outlet for the plant, Martineau creates an incentive for further collection and disposal, potentially limiting the weed’s ability to colonise new areas.
Officials have noted that innovative uses for invasive species can complement traditional control measures. Martineau’s project demonstrates a practical application that both addresses an ecological concern and generates a marketable product. The effort in Abercorn reflects a broader trend of community‑based solutions aimed at managing invasive flora across Quebec.
