Why giant hogweed is a problem in Belfast
On Belfast properties, giant hogweed sap causes severe phototoxic burns and long-term light sensitivity, which makes it a genuine safety issue on footpaths, riverbanks and school boundaries. In Belfast, Japanese knotweed and Himalayan balsam spread along the River Lagan and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Belfast Lough and Cave Hill, along with new housing on the edge of town towards Holywood and Dundonald, are where we most often find established stands.
