Last July I blogged a post about a trial that I thought was worth undertaking on the hard to kill Japanese knotweed. The original post can be found here by following this link www.ayrshireriverstrust.org/blog/2014/07/31/japanese-knotweed-trial/
It was a very simple experiment to see if the plant could survive desiccation following 5 days in the cab of the van in warm weather. It would appear that it can’t as the photo below confirms. Well at least that’s one way of killing it even if it isn’t the most practical method.
