Why Japanese knotweed is a problem in Stevenage
On Stevenage properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. As one of the first post-war new towns, Stevenage saw extensive earthmoving during development, and knotweed has since colonised disturbed verges along the River Beane and old railway sidings near the original town.

How we treat Japanese knotweed in Stevenage
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
Stevenage and nearby Knebworth, Old Stevenage, Aston.
