Why Japanese knotweed is a problem in Norwich
On Norwich properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Norwich's riverside industrial past along the Wensum and Yare, including old maltings and railway yards near Norwich Thorpe station, has left disturbed ground where knotweed has become well entrenched across the city.

How we treat Japanese knotweed in Norwich
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
Norwich and nearby Thorpe St Andrew, Sprowston, Old Catton.
