Why Japanese knotweed is a problem in Lewes
On Lewes properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Lewes sits on the River Ouse, a major knotweed corridor in East Sussex, and the town's former brewery and malthouse sites, combined with the old railway sidings near the station, offer further disturbed habitat.

How we treat Japanese knotweed in Lewes
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
Lewes and nearby Ringmer, Barcombe, Kingston near Lewes.
