Why Japanese knotweed is a problem in Devizes
On Devizes properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Devizes' position on the Kennet and Avon Canal, with its famous flight of 29 locks, has left disturbed towpath verges where knotweed spreads through former wharf sites and canal-side warehouses.

How we treat Japanese knotweed in Devizes
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
Devizes and nearby Rowde, Roundway, Potterne.
