Why Japanese knotweed is a problem in Bristol
On Bristol properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Bristol's extensive docklands along the Avon Gorge and Floating Harbour, together with old railway sidings near Temple Meads, have long provided the disturbed brownfield ground that Japanese knotweed favours.

How we treat Japanese knotweed in Bristol
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
Bristol and nearby Shirehampton, Sea Mills, Stapleton.
