Why Japanese knotweed is a problem in Blaina
On Blaina properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Blaina sits in the Ebbw Fach valley in Blaenau Gwent, with terraced streets and former colliery land.

How we treat Japanese knotweed in Blaina
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
Blaina and nearby Nantyglo, Coedcae, Abertillery.
