Why Japanese knotweed is a problem in Newquay
On Newquay properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Newquay's coastal dune systems and former railway sidings near the harbour have provided disturbed sandy ground where knotweed spreads through the Gannel Estuary's tidal margins and golf course fringes.

How we treat Japanese knotweed in Newquay
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
Newquay and nearby Crantock, St Columb Minor, Quintrell Downs.
