Why Japanese knotweed is a problem in Aberdare
On Aberdare properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Aberdare sits in the Cynon valley, where former coal tips and the River Cynon's disturbed banks carry knotweed down from the heads of the valleys to the Taff confluence at Abercynon.

How we treat Japanese knotweed in Aberdare
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
Aberdare and nearby Cwmbach, Aberaman, Trecynon.
