Why Japanese knotweed is a problem in Ystradgynlais
On Ystradgynlais properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Ystradgynlais sits at the upper end of the Swansea Valley, where former quarry, coal and tinplate land along the River Tawe gave knotweed a stronghold that recurs on disturbed banks toward the Brecon Beacons.

How we treat Japanese knotweed in Ystradgynlais
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
