RApologies for reserecting a year old thread (almost to the day), but could someone tell me for definite if this is Japanese knotweed please?



Because if it is, I think my neighbour (and possibly me) may have a problem....this tree is covered in it

Ok. Get a picture of the stem at ground level and a flat picture of a leaf, then I will be able to tell - I recognise the stuff easily now!!

Samples from the web:








Your photo's certainly close, I suppose. But yeah, as above, need a photo of the stem and the leaf.

looks like russian vine to me (otherwise known as mile a minute)?
If it is, its not a problem. I grow this stuff on purpose to act as a natural fence

One thing I notice with knotweed's leaves is that the part of the stem where the leaf spouts from is like a junction, almost as if the plant's fighting with itself.

Just waiting for my latest pics to load, but I think you may be correct with the vine.

£4 a plant?

I've got tons of the fecker here - I could retire on the proceeds.

I can't get to the stem at ground level as its over the fence, and I can't see it for vegetation (part of my neighbours garden that I don't think he knows exists - he has about 1.5 acres...)

This is what is growing over the fence -



And here's a leaf -

Hello wavey

That looks like Russian vine. It's related to Japanese knotweed but not as problematic but can still be a pain to get rid of as it grows like lightning.

Doesn't look like knotweed - kill it with regular sprays of glyphosate/picloram and you'll be fine...

Slightly off topic, but how would one become a "Specialist" in eradicating or at least treating Invasive Species such as Knotweed? I have a Ground work company and wouldn't mind creating a sub branch specialising in invasive species and more specifically - Japanese Knotweed.

I would want to have all the training and have the ability to professionally "brag" about our knotweed treating credentials. Would every person working for my company have to be trained to the same level or would one suitably qualified supervisor overseeing operations suffice? Any detailed information on this would be much appreciated smile

This stuff works. Break off some of the stem and use the included dropper to pour some down the hollow middle:

He's not wrong...I have it in my garden, and while its easy to pull up and clear, it grows at a mental rate. If you don't keep on top it it it gets everywhere.

Qualifications in professional pesticide usage, then specific qualifications in the chosen application method. I assure you in a professional setting it isn't as simple as sloshing some weedkiller about.

I appreciate that. However would you like to expand on this comment? If I was serious about becoming a knotweed eradication specialist what would be the best route to go down? Are there any specialist courses or is it simply a case of acquiring NPTC PA1 & PA6? If I wanted to start injecting knotweed what would I require, PA13?

Once I acquired these and all the EA licences to dispose of any knotweed clippings etc can I then simply promote myself as a knotweed eradication specialist?

This may be a good starting point...........

Personally I would look at employing somebody already in the business maybe on a commission basis?

Having reread the thread I am seething over the previous owners actions. I'd have hunted then down and used their blood as a herbicide. mad

Utterly outrageous statement - blood is actually a pretty good fertiliser. wink

I'm pretty certain this isn't Japanese Knotweed but could someone please help identify it and if removal would just be a case of painting the leaves with a Glyphosate based weed killer? It's the broad leaved plant not the narrow one with the red canes which is the bamboo.





It's growing up and entangling itself amongst a bamboo plant I've recently bought and planted. I've managed to untangle much of it from the bamboo so far so can access the leaves without touching the bamboo.
