Japanese knotweed is a plant so invasive it is like a species from a horror B-movie. It can force its way through concrete and roadways, block drainage channels and damage foundations and is notoriously difficult to eradicate.
Now it seems it is spreading around the Northern Ireland countryside. And it has its enemies in disarray. No single agency is responsible for its eradication, in spite of its invasive qualities, a shortcoming that could see it spread unchecked. It is time that a concentrated and cohesive strategy for dealing with the weed is drawn up and implemented.
