Why Japanese knotweed is a problem in Southport
On Southport properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Southport's dune systems and the disused Cheshire Lines railway embankments have allowed knotweed to spread from Victorian pleasure gardens into the Marine Lake surrounds and coastal nature reserves.

How we treat Japanese knotweed in Southport
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
Southport and nearby Ainsdale, Birkdale, Churchtown.
