- Treating Japanese Knotweed pt 1 - Weeds
Japanese Knotweed is a destructive and invasive species which has to be killed off and/or burnt. Most councils need to be informed if you have it as it can be so destructive to buildings and the like. Hopefully this video can help get rid of your problem.
This treatment in the video has been continued spring and autumn since the video was recorded and this particular infestation is now dead.
There are more videos in this series and there are additional videos recorded in the pipeline for publication. If you want to follow us on social media, you can find me, Nick Barban, owner of LawN & Border, at any of the following:

Thank you.
One of the best videos I have seen.
New Subscriber I really appreciate it please provide any update you can thank you
Adam Slosar thanks for subscribing. Just remember, this is the way I have done it. Works for me. Others will say this way is wrong etc. Go the safe way and get a certified contractor to treat it. It will take a while. Expect absolute minimum of 3 treatments and then control after that. Hope you get it sorted
thank you!
The stem filling method is most effective in April/May when the shoots are young and the leaf spraying is best done in September when it's flowering.
Also, buy a 5L tank at the very least, that "toy" is for clearing the driveway cracks.
When I have cut knotweed, I have found that at each leaf, the stem is NOT hollow. There's a fiberous material there. Only under the most bottom leaves do you squirt the herbicide.
The point of this video is that JKW is not indigenous to the uk and has become a major problem all over the country. So much so, that this plant, that is a medicine, is reportable to local councils for scheduled removal. Mortgage acceptance have been put on hold or cancelled because of this invasive plant and my job is to remove it from where it's not wanted. After all, a weed is a plant in the wrong place and as time has shown, this one should have stayed I Japan
you should also show what the product looks like, where from and how much?
Looks like a great method to get rid of knotweed, unfortunately, I need to get rid of it at an apartment building with small children and I'm hesitant to use pesticides in an area that they're going to be playing in.
wondering what to do with the very young shoots coming up? iv about 3 to four tall stems and you made that clear on what yo do thanks.
Hi Andrew. If they’re really young, just spray the leaves. Hopefully that might nip them in the bud! Thanks for posting. Nick
Hi joe. No, you can't. The root system goes on forever. Consistent systemic or translocated treatment in the stems and on the leaves is the way to go. Digging it out is like trying to dig the roots out on ivy or ground elder. A waste of time
Hi Nick, thanks for the video, very clear. In your experience once you start treatment does it stop/stunt the growth getting any worse?
+Cemento yes. Initially it may just slow it but if your mix is strong enough it should stop further growth and spread quite quickly. N
As with all pesticides, you need to be careful around children and animals. One option that you can work with this, is to just do the internal treatment so there is nothing on the external leaves. If you do it this way, you could double the SBK stump killer or equivalent as you would only be treating the internals of the plant. Either way, your still looking at a couple of years to kill off this stuff
nick, have you treated knotweed before? because I am really unsure about your method. I have a property with knotweed and have been seeking knowledge to deal with this problem. i have read extensive information so far and have also met with a knotweed specialist. His quote to get rid of 21 stems and 2 stems on a neighbouring garden over a 3 year period treating the knotweed twice a year was going to cost 5,000 pounds inc vat. this is why i want to stem inject myself. any other tips??
Keep the kids away from the treated ares for a day or so so that any overspray onto the leaves has dried/absorbed. Yes, kids love to put anything in their mouths or licking things. Fortunately, kids don't do that with plants (most of the time), but if they do, seek medical advice immediately and tell the paramedics exactly what the JKW has been treated with. In 12 yrs, this has not happened once :)
Hi Nick.... Please give me an update ... and maybe a video of part 2 :-)
+Tommy Gee hi Tommy. Part 2 to what. I've not done a pt2 to the knotweed treatment
I'm sorry .... What I meant to say... is your method working..... thank you ...
+Tommy Gee yes it is. I'm at that site a very fortnight and all that's left atm is 1 stem that's in the hedge. I'll do a follow up video when I'm there next (this week I think)
Thank you...I am going to try your method...thank you again
Tommy Gee cool. Good luck and be patient. It can take a few years to clear, so don't expect 1 treatment to do the job
Is it good to inject each stem as well as spray it ?
Hi H K. It’s preferable. It’s a SOB to deal with and last year the RHS reclassified any treatments for JKW as control rather than eradication. Best to inject every hollow stem and spray the leaves, avoiding any overspray. Thanks for posting. Nick.
Hi john. Yes, sulphuric acid would certainly do the trick but it's not something I would recommend - privately or commercially. The persistency rate of sulphuric acid is very high and will stay I the ground for well over a year and affect the growth of other plants around it, apart from it being illegal to use in the treatment of JKW! Or any other weeds for that matter. Hope you were wearing gloves and a face mask and goggles
I did dig up moste of the rots and burned everything where it sat in the fall. Then put a thick rubber mat over the area. And now in the sumer when it shots out a few shuts far away outside the rubber mat i pick them straight away. That most kill it right? if it can't grow it will need to decomposte after a year or a few years right? its a really damp and rich soil btw
Hi Lucas. You’d think, wouldn’t you. Unfortunately, all that will do is cause it to spread faster. All the root system under the the rubber mat will just lye dormant, possibly for years and when it’s uncovered you’ll have a forest. It’s needs to be treated, usually a number of times over a number of years. Latest research says that most treatments won’t kill it, only control it. Your best bet is to speak to a local specialist and have a look at what you’ve got when it’s in active growth. Burning what you remove is absolutely the right move - even burning the cutting over the JKW stems won’t kill it though. Hope that helps. Thanks for posting. Hope to hear from you again soon. Nick
@@NickBarban okey then i just let the rubber mat lay there. Will build a small cabin there. Just build it over it then i quess haha. It does not have anywhere to spread really. And it's a Japans knotwed have hade some look at it and they said dig it up over and over agien and i will lose the battle. And thx for the raplay greatings from northern parts of Sweden
@@NickBarban
@@P4hko Any luck?
@@voxdomesticus they are gone to 90% but still ain't dead. Think it helped that I diden't covver it all so I could still drain energy from them. Aperently they can go dorment for like 10-15 years I they don't have room to grow.
Has anyone ever tried pigs that eat all sorts of plants including roots? I wonder what happens to Japanese Knotweed if pigs eat at them.
+Pink Lady cattle, sheep and humans can consume JKW. It's not toxic to them. In theory, not toxic to pigs, but that's just a guess. In my opinion, probably not a good idea to let them eat it. They wouldn't get all the roots and they would spread the rhizomes and you would end up with a forest of JKW. I guess that's not what your looking for
Nick Barban, I just looked at other treatment s for weeds. I came across weed steamers which are now being increasingly used by farmers. I wonder if the most powerful ones have ever been tried on Japanese knotweeds. My mother uses boiling water on ordinary weeds growing in tar. It works for her. I don't know it works on JKW.
I found something on steaming Japanese Knotweed.
www.soil-steaming-steam-boiler-blog.com/2015/07/freiburg-regional-council-once-again-uses-steam-against-japanese-knot-weed/
Yes people have used goats to eat the surface plant, and pigs to eat the roots in combination. I don't know what the results are though.
@@kinny2098 I recommended the pig method to a farmer who borrowed his neighbors pigs for a couple of months. The knotweed never came back. The area was about 20m x 25m and he put 10 pigs on it. It was a stand of knotweed about 5m in diameter and 2m tall in the middle of a field. He fenced it off. So yes it can work, but you have to catch it early.
How to spot it? You can't just pick random plants and guess if it's knotweed..
Large teardrop shaped leaves.
Hollow but slightly watery stem
Stem is in sections that are not entirely parallel to one another (a bit of a zig-zag pattern)
Stem has a slight spotted/dashed pattern on them.
Reddish shoots when first growing (kinda looks like asparagus)
Just use gallop 360 or 490 I killed with that never came back
Hi. Is that the Hi-Aktiv? I’ve used the Biograde 360 and it was okay but needed a repeat treatment. Thanks for posting and the advice. 👍
I do as living got all my certificates you really ment to inject it into stem for that I’ll charge about £2k I’m license to do that
oh my god this is NOT the way to treat JKW!!! and people have no idea what theyre talking about, this video needs banning!!!
Can you link us a video of how to treat Knotweed then? Or share your tips?
@@Cfazio76 There genuinely isn't one. All the land just has to be completely removed.
then how ?
Why?
Just burn out another car next to the weeds.
Job done lol.
What terrible advice.
Why?
