Why Japanese knotweed is a problem in Crawley
On Crawley properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Crawley's development over former woodland and streams draining to the River Mole has left disturbed ground prone to knotweed, particularly along Tilgate Park's lakeside paths and the old railway embankments near the town centre.

How we treat Japanese knotweed in Crawley
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
Crawley and nearby Ifield, Pound Hill, Three Bridges.
