Why Japanese knotweed is a problem in Tredegar
On Tredegar properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Tredegar's ironworks legacy left vast spoil tips along the Rhymney and Sirhowy, and these disturbed banks remain one of the most persistent knotweed strongholds in the South Wales valleys.

How we treat Japanese knotweed in Tredegar
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
Tredegar and nearby Sirhowy, Georgetown, Dukestown.
