Why Japanese knotweed is a problem in Manchester
On Manchester properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Manchester's industrial canal network, including the Rochdale Canal and former cotton mill sites, has left extensive brownfield land where knotweed spreads rapidly through disused railway viaducts and inner-city wastelands.

How we treat Japanese knotweed in Manchester
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
Manchester and nearby Chorlton-cum-Hardy, Didsbury, Prestwich.
