Why Japanese knotweed is a problem in Sunderland
On Sunderland properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Sunderland's shipyards and coal staithes along the River Wear left disturbed, contaminated ground where Japanese knotweed has colonised former dockland and railway sidings, spreading along the riverside from Pallion to the coast.

How we treat Japanese knotweed in Sunderland
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
Sunderland and nearby Fulwell, Grindon, Ryhope.
