Why Japanese knotweed is a problem in Southampton
On Southampton properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Southampton's docklands and the Itchen and Test river corridors provide disturbed, nutrient-rich ground where Japanese knotweed has spread readily, aided by rail sidings around Southampton Central and reclaimed industrial land near the old Itchen wharves.

How we treat Japanese knotweed in Southampton
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
Southampton and nearby Netley, Hamble-le-Rice, Bursledon.
