    Why Japanese knotweed is a problem in Llantrisant

    On Llantrisant properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Llantrisant's hilltop castle and the surrounding former colliery and common land, plus the Ely valley's disturbed banks, give knotweed recurring stands on the town's rural edges.

    How we treat Japanese knotweed in Llantrisant

    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.
