Why Japanese knotweed is a problem in Warwick
On Warwick properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. The River Avon flows past Warwick Castle, and the town's old canal wharves on the Warwick and Napton Canal have long supported knotweed, which also spreads along the disused railway sidings near the town centre.

How we treat Japanese knotweed in Warwick
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
Warwick and nearby Leamington Spa, Barford, Hampton on the Hill.
