Why Japanese knotweed is a problem in Marlborough
On Marlborough properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Marlborough's historic wide high street and the River Kennet's disturbed water meadows have given knotweed a foothold, spreading from the old college grounds into the surrounding downland verges.

How we treat Japanese knotweed in Marlborough
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
Marlborough and nearby Preshute, Mildenhall, Manton.
