Why Japanese knotweed is a problem in Hemel Hempstead
On Hemel Hempstead properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. Hemel Hempstead's knotweed populations are strongly linked to the River Gade and the Grand Union Canal, which pass through the old industrial areas of the town where former paper mills once operated.

How we treat Japanese knotweed in Hemel Hempstead
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.
