Why Japanese knotweed is a problem in Watford
On Watford 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 Colne and Grand Union Canal run through Watford, both classic knotweed conduits, and former printing works and industrial estates near Cassiobury Park continue to harbour long-standing infestations.

How we treat Japanese knotweed in Watford
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
Watford and nearby Bushey, Croxley Green, Abbots Langley.
