I've a possibile giant not Japanese knotweed in the garden. May be something else anyone on here good with plants etc? Obviously I'll be sorted but I'll ask here 1st and say what pictures do you need? Leaves, stem base etc?
Photo showing height, leaves and flowers would be helpful.
Edit misread post
Pix Please.
Inject roundup (Glyphosate) into every stem.
Rather than inject it, just spray the foliage with Glyphosphate (round up). Once it's dead and dry bag the seeds. Repeat each year until no more plants appear.
Giant hogweed has purple streaks on the stems which can be jam jar diameter. Leaves typically 500mm across and the deeply lobed leaves are serrated. The leaves are typically more vibrant than the more muted hogweed.
It's also big. But native hogweed can reach 1.8m - 2m with narrow stems with white hairs.
Back to the OP. you think you have a large specimen of a native hogweed? NOT a giant hogweed.
Giant hogweed
But doesn't look much like
Japanese knotweed
Which spraying will knock back the visible plant but not get rid of it. That need will digging out to get rid of the rhizomes then disposing of correctly, as it's controlled waste. So yes, if it is japanese knotweed
Obviously I’ll be sorted
Make sure who ever does it knows what they're doing.
(don't get me wrong "giant not Japanese knotweed" isn't exactly a helpful description but it's not hogweed if it looks anything like)

No, he thinks he has Knotweed.
Make sure you follow the disposal restrictions and good luck it’s notoriously difficult.
Giant Knotweed is a plant that looks similar to Japanese Knotweed. It's not the same as Giant Hogweed.
I have seen both but my partner will give you advice on idetification.
We have a cycle ride we call the ride of invasive species which has includes Giant and Japanese Knotweed as well as things like giant Hogweed.
We had some Japanese knotweed in the garden of a house we bought (couldn't get a mortgage until owners had a treatment plan in place, that cost several £k).
It does occasionally come back and then I put roundup gel on the leaves and it goes away again.
Don't dig it up unless you know what you're doing as you'll only spread it, each bit of root can grow again.
Oops. Sorry. My mistake. Ignore my hogweed chat.
Knotweed is bad stuff to have, due to its pervasive, invasive nature, but giant hogweed is really something you don’t want, because it’s seriously harmful stuff if you just touch it! Just Google hogweed burns…

Pedant mode...
Rhyzomes aren't roots
I don't think its knotweed. Though google lense keeps suggesting it.
Wtf is it!
Pretty sure that isn't knotweed, it's too woody and I don't think knotweed has those berrys. I think we have that next door, overhangs our fence, if it's the same thing it grows way more slowly, I just cut the odd branch back from time to time. Knotweed can grow a foot a week and dies back over the winter coming back from ground level the following year.
It’s not Knotweed. Knotweed stems are smooth not hairy. They’re also segmented.
The leaves do look like out kiwi but the berries definitely don't
Are the berries not on the other bush it's intertwined with which looks to be a hawthorn to my far from expert eye?
Kiwi growing through hawthorn.
Baby Triffid plants I bet ya !
Bruce - Please look at link in previous post from me yesterday because that will help with I.D. of three types of Knotweed.
Bruce's other half here (Botanist). Apologies for very rushed reply. Photo attached showing two pressed specimens of Giant Knotweed to show typical leaf shape and size range. Note that the magins of the Knotweed leaves do not have any teeth (they are entire margins). Giant Knotweed does not have any hairs on the leaves or stems. Hope this helps you to rule this out for your plant. There are other differences but those are the two which are easiest to describe.
Looks like gympie-gympie plant to me. Good luck!
What's the stem like? I mean, does it grow like a vine or standing up straight & tall by itself?
Yeah the berries are the hawthorn bush.
Not sure what it is but it’s isn’t Knotweed.
I’m pretty positive you’ve got an Actinidia - Kiwi Vine there. Def not knotweed.
