Cumberland Council has urged local residents to exercise caution regarding a highly invasive plant that is spreading across the county.
Japanese knotweed is an invasive weed that is exceptionally difficult to remove and control.
The root system is extremely complex and can obstruct drainage systems and compromise road infrastructures.
The plant spreads rapidly both by natural means and because of human activity, so the council is urging landowners not to strim, strike, cut, mow or dig up to remove it.
Japanese knotweed is spread via fragments of rhizome or stem being transported to new sites and should instead be destroyed with professional glyphosate products, which can be purchased at garden centres.
However, to fully control the plant, this should be done in late summer/autumn after it has flowered, while users should take care not to damage other vegetation.
Councillor Denise Rollo, Cumberland Council’s Executive Portfolio Holder for Sustainable, Resilient and Connected Places, said:
"Our intention is to keep the public informed rather than to cause undue concern. We believe it's important for everyone to know that Japanese knotweed is present in the Cumberland area. Our primary goal is to empower individuals with knowledge about the appropriate steps to take if they happen to be landowners dealing with this issue.
"Japanese knotweed is a highly persistent plant, and our collective efforts are crucial in managing its impact. We kindly urge everyone to take proactive measures to address it. Remember, awareness is the first step toward effective control.
"Together, we can create a Cumberland environment that thrives. Thank you for your attention and cooperation."
Members of the public can public can report Japanese knotweed on highway verges (not private gardens or land) by visiting the council’s website, or by phoning the Highways Hotline, Monday to Friday, 8.30 am – 5 pm at 0300 373 3736.
