Why Japanese knotweed is a problem in Lisburn
On Lisburn properties, Japanese knotweed rhizome spreads several metres underground, exploits cracks in hard standing and drains, and can stall a mortgage offer or sale. In Lisburn, Japanese knotweed and Himalayan balsam spread along the River Lagan and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Lagan Towpath and Wallace Park, along with new housing on the edge of town towards Hillsborough and Moira, are where we most often find established stands.

How we treat Japanese knotweed in Lisburn
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
Lisburn and nearby Hillsborough, Moira, Dromore.
