Knotweed survey to establish size of problem in Cork City

A city-wide survey of the invasive Japanese knotweed plant is to be undertaken across Cork next year to establish the full extent of the problem. The knotweed’s growth can render homes unsaleable.

City councillors welcomed the move, following calls from authorities in Cork county and Kerry, earlier this year, for a national programme to eradicate the weed.

Its presence can affect the granting of planning permission and can prevent the issuing of mortgages.
