Why Japanese knotweed is a problem in Blackburn
On Blackburn properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Blackburn's former cotton mills and coal workings along the Leeds and Liverpool Canal left disturbed, damp ground where Japanese knotweed has flourished, particularly along disused railway sidings and old millrace channels.

How we treat Japanese knotweed in Blackburn
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
Blackburn and nearby Mellor, Feniscowles, Wilpshire.
