Japanese Knotweed. Maybe. What do I do?

I think I might have Japanese Knotweed on my garden. Please help.
Living in London means,living in very close proximity to each other. In my area the Victorian houses are split in two flats and each flat gets half of the garden. Between my garden and my neighbours garden there's only a foot high wall which I have heightened with a bamboo fence. So weeds transfer easily.
I've been watching the bluebells appear in my neighbours garden. And have noticed that this weird stems with red speckled have started to sprout at a crazy speed. Both the bluebells and one of those stems have appeared in my garden.
I just looked up pictures of Japanese knitwear. And I believe that's what it is. I have heard this is incredibly invasive. What do I do.
I will post a picture tonight.

 

Hide!!!!!





I would be frightened of this entering my garden too



Umm not an expect on japanese knotweed but i think you have to use a chemical treatment to fully kill it that needs to be injected in the stems. Fingers crossed its a plant that looks like japanese knotweed and not the deadly stuff

 

I really hope it isn't kbotweed. But I have a bad feeling. Mist people in my area don't look after their garden. It's weed heaven.
What looks like Japanese knotweed.
Would I need to notify my landlord? Apparently it can devalue property

 

If it is japanese knotweed I think you would have to notify you landlord and I think he/she would have to pay for its removal but Im not sure. pretty sure someone else will know

 

Hmm that will be hard. Our washing machine is broken and we've been asking him to repair it for other a month now. I doubt he'll get it removed.
But it can devalue his propert. So it probably is my responsibility to inform him. Can I kill it with weed killer?

 

Found this on the RHS it might help

"Perhaps the most effective and simplest method for the home gardener to tackle Japanese knotweed is with the glyphosate-based weedkiller Scotts Roundup Tree Stump & Rootkiller. This has label recommendation for controlling Japanese knotweed, instructing it to be applied to the cut canes. Bayer Garden Super Strength Weedkiller also has label control for this weed"

 

Thank you Dips. I will post a picture tonight to identify it. Then I'll notify my landlord so I've done my duty. Then attack it with the glyphosate weedkiller

 

I have 2 fields next to me that have the dreaded stuff. Did you know that Alan titmarsh grows the stuff. He keeps it in a pot and cuts back new shoots as they appear to control it. He likes the flower apparently. The owner of one of the fields near me just cut it back to ground level. Their thinking is that it's waste ground for horses not a thought to the neighbouring gardens I'm afraid. I reported it to the council who showed no interest. Short of nuking your garden you will only be able to control it as its spread is astounding. It's supposed to be a controlled substance but as I say the authorities couldn't give a monkeys. You do have my commiserations indeed.

 

All that doesn't sound good :( Even with the off chance that the landlord pursues it. It's all other tg e neighbours garden. So unless they do smthg it will keep growing in ours :(

 

If it's Japanese Knotweed, i've heard that the best way to kill it is to cut the stems to about a foot tall and then put strong weed killer into the stems but you will have to keep on repeating it, i've not done it only what i've heard but it's going to be a long job, good luck

 

Hi Jiffy ,
I agree with what you have said but you use that method in Autumn as the plant is dieing down and the glyphosate get sucked in to the roots in the ground over the winter and it has the best effect

 

Just thinking, if some one planted Japanese Notweed in there garden as a flower and you start to kill it because it coming into your garden, can you get done for killing it??? (just thinking)

 

No, they'd get done for letting it spread, according to https://www.gov.uk/prevent-the-spread-of-harmful-invasive-and-non-native-plants
"However, if you allow Japanese knotweed to grow onto other people’s property you could be prosecuted for causing a private nuisance"

 

It's illegal to plant it and it's the property's owner's responsibility to stop it from spreading. That much I do know

 

I doubt they planted it anyway. I don't think they planted anything to be honest. Probably renting the flat too.
I'm on my way home. Will post pictures soon. And hopefully someone can identify it (as not Japanese knotweed preferably). If it is I will let them know and my landlord
