Ha ha, get the glyphosate out. ??☠️☠️

[Ronan 1]

Oh no.... fecking horrible stuff. Did it come from neighbours "managing" it.

[SteamyTea]

No idea where it came from, the area has been free of it for several years now.

Glyphosated it, but that will probably kill some stuff around it, including the echiums and bamboo.

Stem inject it, don’t spray. 

Large syringe. 

[SteamyTea]

Luckily it has taken root in a large planter, so when it dies down a bit, I can remove it, along with the bamboo.

make sure you notify the council (As Jap knot weed is a notifibiable weed) just so they can log it against your property, and make sure it comes up on any future searches and de-values your property accordingly... Or, Kill the bar-steward, and tell nobody. Had some at my daughters tiny garden 10ft x 10ft total garden size. i spent 2 years spraying the crap out of it on a weekly basis. ( Over the top, and a waste of weed killer). Then dug it out, took 12" of soil out, and stuck 6"of concrete over 6" of rubble, over a geotex membrane.......I've never seen it again.

Cornwall had a large program to eradicate JKW a decade or so back. It was largely successful and I have not seen any for a good few years now. So this was a complete surprise. 15 years ago I started spraying it when it appeared in the car parking area. Couple of years of monthly spraying and it went away. Shall go out and check the area tomorrow when everyone has gone to work.

If it really devalued property, why have homes in Cornwall always been relatively expensive.

I see companies promoting opportunities for reps to take up reporting of this. Presume there is some bizzare financial incentive

Not any more.

We have some around me on verges etc, we take it in turns to spray it and it’s no worse.

[SteamyTea]

Does seem strange that it found its way into my planter. Right where I found the crossbow bolt.

Do you think some evil genius is going around coating crossbow bolts with JKW spores and then loosing them off at the planters of people they find tiresome.

Evil genius types tend not to have tiny minds - the clue is in the word genius, but I appreciate the sentiment...

Eh, what crossbow bolt?, can’t this be spread through seeds blown in the air???

In the U.K. all Japanese Knotweed is propagated by vegetative cuttings from a single female plant. https://www2.le.ac.uk/departments/genetics/people/bailey/res/f-japonica

[joe90]

However…..from the above piece….

 

Since only female plants occur in Britain they are unable to reproduce sexually, but are available for pollination by any related species in the area.  This they do very well, and most seed collected from F. japonica in Britain is the result of pollination by the related Russian Vine (Fallopia baldschuanica), to give Fallopia x conollyana. In locations where Japanese Knotweed grows close to male plants of Giant Knotweed or the hybrid F. x bohemica, enormous amounts of seed can be produced some years.

Let it dry out and then burn the lot, bamboo and all, not worth the risk trying to separate them.

Nooooo. Just burn the planter, knot weed and all.

[DavidFrancis]

Google reckons it could be Himalayan honeysuckle. 

[SteamyTea]

Pretty sure it is knotweed.

May burn it. Or just take it to the dump where they have a special place for it.

[PeterW]

Leaf position is incorrect for knotweed - it grows from alternate nodes on either side. Also the leaf colouring is unusual for knotweed as it is ordinarily green with red veins. 
 

That looks more like Himalayan Honeysuckle as @DavidFrancis said.
