Why Japanese knotweed is a problem in Northampton
On Northampton properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. The River Nene and Grand Union Canal both pass through Northampton, historically linked to the town's leather and shoe industries, and the disturbed brownfield land left by former tanneries continues to support knotweed growth.

How we treat Japanese knotweed in Northampton
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
Northampton and nearby Duston, Kingsthorpe, Weston Favell.
