Why Japanese knotweed is a problem in Cwmbran
On Cwmbran properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Cwmbran's new-town construction exposed fresh disturbed ground across the Afon Lwyd valley, and knotweed quickly colonised the canal and railway corridors that run through the town's edges.

How we treat Japanese knotweed in Cwmbran
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.
Local coverage
