Japanese Knotweed is a notoriously invasive plant, so it is important that it is identified as early as possible, in order to mitigate the damage it can cause to your property. With professional consultation and removal, japanese knotweed problems can be dealt with. However, for this to happen, it needs to be correctly identified in the first place so the issue can be reported.

One of the complications involved with this is that many people cannot determine the difference between Japanese Knotweed and other similar, but harmless, plants from the same family. A recent study has revealed that four out of five home owners are not able to successfully identify the problematic plant. If you form part of this 80% of the population, we have put together this guide with you in mind, so you don’t get caught out by failing to recognise Japanese Knotweed.
