Why Japanese knotweed is a problem in Amersham
On Amersham 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 Misbourne, which flows through Old Amersham, is a classic knotweed corridor in the Chilterns, with additional infestations found around the former brewery and railway yard sites near the town centre.

How we treat Japanese knotweed in Amersham
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
Amersham and nearby Chesham Bois, Little Chalfont, Coleshill.
