Why Japanese knotweed is a problem in Colchester
On Colchester properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. As Britain's oldest recorded town, Colchester's Roman walls, former garrison land and the River Colne towpaths provide disturbed ground where knotweed rhizomes have spread unchecked through allotments and old railway cuttings.

How we treat Japanese knotweed in Colchester
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
Colchester and nearby Wivenhoe, Fingringhoe, Marks Tey.
