Why Japanese knotweed is a problem in Flint
On Flint properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Around Flint Castle and the Dee estuary, Flint's mix of gardens, riverbanks, railway corridors and development plots gives invasive and persistent weeds plenty of disturbed ground to colonise, and infestations regularly cross property boundaries across North Wales.

How we treat Japanese knotweed in Flint
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
Flint and nearby Bagillt, Holywell, Northop.
