Unseasonable Japanese knotweed

Published on 18-11-2009 by Dr Paul Beckett

We’ve not really had a frost yet down in the south of England. Consequently, there’s still some areas of unseasonably healthy Japanese knotweed growth about. It often surprises me how sturdy and resilient Japanese knotweed is. The photograph above is of some Japanese knotweed growing quite happily in amongst the concrete of East London in January, during a particularly mild winter in 2007! If we don’t get a frost soon, we might see similar knotweed growth this winter.
