Japanese Knotweed Identification in Spring

Posted on

If you live in the UK, you will have noticed the incredibly mild winter we have just had. While typically a lot of us will be happy to have seen the back end of it, those of us who have a Japanese Knotweed infestation on their premises will have a feeling of dread when they see the tell-tale red shoots coming back up earlier in the year than expected.

 

Around this time of year, you can expect to see Japanese Knotweed shoots starting to come through with red/purple speckled stems. You may also notice that the Japanese Knotweed plants may have leaves that are furled with red veins running through them – by the end of the month, these leaves will have unfurled fully, displaying their distinctive heart shape. The leaves also alternate in a zig-zag formation; this being one of the key characteristics to look out for when identifying the invasive weed.

 

Treatment at this time of year is usually not recommended as it can be ineffective, waiting until mid-May, when the plant has had a chance to develop, is a lot more likely to have more of an impact on the weed, as there is a lot more green growth to absorb the active ingredient in the herbicide.
