Why Japanese knotweed is a problem in Abergavenny
On Abergavenny properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Abergavenny's position at the Usk gap, with former railway and canal land around the town, gives knotweed disturbed corridors along the riverbank and onto the lower slopes of the Sugar Loaf.

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.
