Why Japanese knotweed is a problem in Warrington
On Warrington properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Warrington's dense railway network, old chemical works and the Manchester Ship Canal have created disturbed corridors along the River Mersey where Japanese knotweed proliferates, especially near former wire-works and tannery sites.

How we treat Japanese knotweed in Warrington
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
Warrington and nearby Lymm, Stockton Heath, Grappenhall.
