Japanese Knotweed Found in Wisbech

Japanese KnotweedWe spotted a rather worrying report from the EDP about 5 sites in Wisbech and Whittlesey where there is Japanese Knotweed growing. No doubt you’ve heard of it and know it’s an invasive plant that can undermine brickwork and concrete causing serious problems.

The good news is that is doesn’t spread by seed and the bad news is that even a tiny piece of root left in the ground can grow into a plant. And the worrying news is that this photo in the paper doesn’t really help to identify it. Non Native Species Secretariat has a really good list of fact sheets to help do that here: http://www.nonnativespecies.org/index.cfm?sectionid=47
