    Why Japanese knotweed is a problem in Castlebar

    On Castlebar properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. In Castlebar, Japanese knotweed and Himalayan balsam spread along the Castlebar River and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Lough Lannagh and Turlough Park, along with new housing on the edge of town towards Turlough and Balla, are where we most often find established stands.

    How we treat Japanese knotweed in Castlebar

    Treatment method

    We use a three to five year stem-injection and foliar herbicide programme, or hybrid and full excavation with licensed off-site disposal where timescales are tight.

    Best timing

    Most effective late summer to early autumn, when the plant draws herbicide down into the rhizome.

    Your legal position

    Listed on Schedule 9 of the Wildlife and Countryside Act 1981 — allowing it to spread to neighbouring land can bring a civil claim, and the cut material is controlled waste.
