Why Japanese knotweed is a problem in Lancaster
On Lancaster properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Lancaster's historic quayside on the River Lune and old canal basin have left disturbed riverside ground where Japanese knotweed spreads along the Lune's flood banks and former industrial wharves near the city centre.

How we treat Japanese knotweed in Lancaster
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
Lancaster and nearby Halton, Caton, Slyne.
