This plant is very invasive. It is all over the town I live in. I had a lot of it in the corner of my yard next to a fence. I accidentally got rid of it about fifteen years ago. Here is what happened. I had been away for a couple weeks and the grass in my lawn had grown really tall. So I bought myself a brand new lawn mower with a bagger attachment to mow my lawn. I mowed with my new mower and I kept dumping the grass clipping in the corner of the lawn where the knotweed grew. I only put the grass clipping there because this area of my lawn was unusable with the knotweed. Anyway I ended up with this huge pile of grass clipping on top of the knotweed. After a few days I noticed the huge grass pile was starting to generate heat as it was turning into compost. So I removed the compost grass pile from my yard and the knotweed never grew back! I don't know if it was due to the heat or something about the compost pile. I just thought I would share this as I haven't seen anyone else do this. My yard is still mostly free of the knotweed, but unfortunately my neighbor still has it in their yard on the other side of the fence.

HOW DO THE JAPANESE KEEP THIS IN CHECK ???

Roundup injected into the hollow stem is effective in controlling Knotweed.

Just trying to find knotweed it Lego Fortnite

I got rid of most of mine by cutting it down to the soil, getting huge vinyl mesh tarps (my source was free, from riggers who remove giant building wrap billboard ads) then putting 2" of earth or mulch on top to smother it. Some people use old carpeting. The bigger the better, they find any seams.

I see no instruct on methods to get rid of it.

Thank you for the thoughtful video. In North America, we are way behind you in awareness of the problem with invasive knotweeds. Regrettably, we may be ahead of you in creating more virulent hybrid species of knotweed from the four widely recognized species over here. We have had the best luck with successive applications of herbicide in the fall. This first shot is very successful at killing most of the underground rhizome. Thereafter, we use targeted applications of a different herbicide and mechanical removal to deal with the stragglers. It seems after the first shock of herbicide, the colony goes into semi-dormancy. I wonder whether that can be attributed to the plant's origins in Japan where it had to survive periods of heightened volcanic activity.

Being from the United States, I find it comical that I am about to send China money for a dried bag of this. it is considered an invasive species here in the US...even though it has highly profound medicinal properties. Sometimes nature screams in the face of our species, but to no avail. So, to China my money will go...Simply because it was cheaper, and in bulk, i suppose they don't have a problem with availability, or invasivity.

I still remember on a uni field trip near Juniper Hall fsc, my professor tried to pull out one of these large bushes by a small stream as an example and after about a minute, he realised all he had done was break off many tiny bits that floated away, thereby making it a lot worse! No one had the heart to tell him what was happening behind him as he furiously tore away at the plants stems and roots. Oops!

Very fine production. Thanks.

Thanks for the informative video. I appreciate your work.

Any updates on this, did they find anything to inhibit battery cell expansion?

Thank you to these nice Intelligent People, I really enjoyed this

Thank you. It’s so invasive and any information about control is valuable.

I really enjoyed this, thank you.

What about watering it with a super low or high Ph water. could that kill it?

Great video, v informative.

Nasty stuff, I once discovered a whole load of household waste and garden rubbish dumped at a friend's wood. In all this was some of this Japanese Knotweed. I know what a problem it is from my days on the railway, it'd even try and undermine tracks, grow up through seemingly impermeable tarmac, etc ! The only thing I could think to do was to burn it. Completely. Thankfully, touch wood, thus far, no sign of any growth. Just as well as the immediate area contains SSSIs.
