Japanese Knotweed...Say it isn’t so.

Having backfilled a recent landscaping project at home with bought in blended topsoil, I was miffed to see that the beds have become a botanic garden of weeds during the 10 days I’ve been away. Annoying, yet on closer inspection, and more worryingly, I’ve got a Japanese knotweed suspect among the motley crew of weeds. The rhubarb coloured speckled hollow stems with alternate leaf nodes being the give away, yet the leaves themselves don’t seem to be the heart shaped ones synonymous with JNW. Any confirmation of what this is will be greatly received.

Thanks!

Ben

    No they are not Japanese Knotweed. The photo looks like Persicaria Maculosa, an annual weed.

    I think it's Persicaria maculosa but a look at the plant, rather than bits, and an indication of size, would be helpful

    It doesn’t look like it to me, possibly willow herb?. This is what Japanese Knotweed looks like :smile:

    No not Knotweed.
    The whole truth is an instrument that can only be played by an expert.

    Persicaria  maculosa aka redshank is a common weed of arable fields ... I spent many hours hoeing it out of sugar beet fields. It’s a very shallow rooted annual ... pull or hoe it up. 
    If the seeds are in the soil it’ll probably reappear for the next few years but you’ll soon learn to recognise it as a seedling. 
    Its one of the things that happens when bringing in soil ...

    Psst Dove, do you get a £ for every time to mention hoeing the sugar beet fields?
