Why Japanese knotweed is a problem in Crowborough
On Crowborough properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Crowborough's elevated position on the Ashdown Forest sandstone ridge means knotweed tends to concentrate around disturbed verges and the old railway cutting, as well as streams draining towards the River Medway headwaters.

How we treat Japanese knotweed in Crowborough
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
Crowborough and nearby Jarvis Brook, Rotherfield, Mark Cross.
