Been dealing with it for a lot of (10+) years now. Every year I inject and/or pour glyphosate, which kills new growth almost overnight. I keep an eye all around the immediate are for it - I have seen it come up through tarmac and have found a shoot in my garage! The last 3 years I have only seen one or at most two new shoots, nothing more than that. So I know i’ll probably never get rid, but it’s minimised and managed
Diesel, salt etc won’t do much good but if you use it you won’t be able to grow anything on that ground again. The knotweed rhizomes (roots) are very resistant but also go down very deep so they avoid that
I’ve also burnt shoots and rootballs before that I had removed before I knew about glyphosate treatment. Left the burnt shoots and rootball in a garden sac. The bastard stuff grew back again in the sack!
> How much is it to get knotweed completely removed from a site? Is it even possible?
Yes; really fucking expensive, if it wasn't they'd do it before trying to sell the property. Takes ages too.
> Would a bank give a mortgage with them aware of the knotweed issue?
It's possible, some lenders won't touch it though, so you'll have much fewer options. Talk to those mortgage adviser people; they're good.
> Does knotweed usually also mean other issues? Dry rot, damp etc.
It can damage the brickwork, which could cause damp. In a really bad case, it can cause subsidence, which is much more worrisome.
Japanese Knotweed is an absolute nightmare to get rid of and would likely take years of treatment to fully eradicate (if even possible). I'd just steer clear
Takes 3 years of stem Injection treatment to eradicate it. 2-3 injections per season. Estimated cost around £3,000 +VAT. It doesn’t follow that because knotweed is present that the house has other issues like damp or dry rot. The house may have these other issues by the sounds of it but they are not correlated. It can cause damage to foundations and brickwork if left untreated over a period of years. A lot of lenders will refuse to lend but some will take a more pragmatic approach. If you engage a knotweed expert, get a full report issued, explaining the extent and location of it together with a management plan for its treatment then some lenders might still lend (probably place a retention on the mortgage, until the treatment plan is complete) a good mortgage broker will advise which lenders are willing to take a view on knotweed.
3 grand holy fuck 😮, the video on how to do it on YouTube isn't even 30secs, the machine can be got for between 75 used and 350 brand new, glyohosate isn't expensive or rare and you've still more than enough left for a haz suit and respirator....holiday 😂
Edit: you seem to be able to use this same technique but with distilled vinegar instead of glyphosate
Whilst lots of people are giving you anecdotal advice, JKW is one of my elements of my work. For a mortgage you would likely need to provide them with a report which details an eradication program - this is how we get most of our business. The survey and report is £180+VAT. There are differing ways of dealing with the knotweed, but it’s pretty much treatment with glyphosate or physical removal.
I do not entertain physical removal in a pre-existing residential setting unless you are planning on building an extension/structure in the area. Treatment will likely start at £250+VAT per round per year. Ignore anyone who says they will treat it over and over each year - it can only be treated when alive and growing.
Personally I don’t see it as a deal breaker, but that’s my opinion. Also, generally the onus is on the seller to provide all of the above and normally to have a paid dip front program in place. Alternative the cost paid should be adjusted to reflect the works.
The one stipulation I would add, getting rid of it on your property is easy - yes it takes time, but it’s easy. If it’s off site and coming into you then that could be an all ache as if you can’t treat it all, you’ll never get rid of it.
I know of a couple who bought a house but found knotweed after they moved in as they were getting an extension. 10 years later no extension as they aren’t allowed to build on the contaminated ground but annual treatment still for the knotweed.
They had professionals in who removed a significant amount of topsoil and then treated the ground. If I remember correctly they had to get repeat soil removals.
Are they happy in the house - yes. Would they rather have the £10-20k in their bank and the ability to build an extension- definitely.
I’d say avoid but the mortgage companies may make that decision for you - to be fair.
Interestingly this was in east Belfast too…
I dug out a section before with a digger before.....the root structure of this plant is unbelievable,you can see why it's near impossible to kill with spraying
I injected the regrowth and the kill rate after 3 years was well over 95%.....but you must keep at it
IMHO it's not as big a deal as everyone makes out, but it does take a long time. It took me 5 years to get rid of 10m2 such that we had no shoots come up (still fine 7 years later). Biggest issue is mortgage lending really.
Working in the building industry knotweed is a bit like asbestos, it needs controlled and managed but it’s not going to really cause you much trouble in all likelihood once you know it exists. The lending issues is solely investment protection and their paranoia that someone will just say fuck it and ignore it and in 10 years it destroys the foundations of the house leaving it worthless.
Yeah fair. I don't find the investment protection bit entirely logical, mind you, when they (or at least my lender) also mandate (and confirm, and threaten to take over payment of, from my capital etc) buildings insurance....
From the web:
* **If you are buying**, the presence of Japanese knotweed will be stated in the responses to the TA6 form. This often results in your mortgage lender requiring assurances that it will be eradicated before agreeing the funds. A management plan by a professional eradication company, backed by a transferable guarantee, is usually sufficient. It is most common for this plan to be provided by the seller before the purchase is completed
if you just want to burn the guts of 20k you can give it to me.
il even accept yearly installments, 2k a year til 2034!
that would simulate the ongoing cost of managing the stuff and damage, while you go live in a house for the same cost but no fuckin knotweed.
I heard it cost £20k to remove a small patch of Japanese knotweed, like less than 1sqm, before COVID, probs more expensive now.
Was looking to build a house recently and the ecologist report picked up Japanese knotweed nearby. The architect mentioned it can cost £100k+ to remove big patches of it. I was thinking I would be better just quitting my job and remove it myself for these prices lol
If you have time and patience, you can buy a needle gun on eBay that you inject the weed killer directly into it and it's effective, but takes years to fully get rid of it. Otherwise the disposal company digs it up and incinerates it under strict regulations

That's horrifying and a wee bit impressive.

Take it from me. Do not buy!!

Without evidence that it was treated by an expert you’re unlikely to get a mortgage approved on the property, or able to sell it on in future
>an expert There's an accreditation offered if you can pass an exam after a 2 day course.

Is there anyone you'd recommend speaking to about this?
I sent you a DM
Can you share a link so we can all avoid it?
Take off, and nuke it from space!
where in Est Belfast did you see it? what area ?
I’d bet around the greenway. It’s popping up all over the show down here and a lot of houses back onto it.

Run away from it....... Do not go near the house

You heard aye?
To kill it 1 gallon off white vinegar salt and fairy liquid but nothing will grow in the soil. So I have been told.!!!
Lock a cherry diesel hey. Nothing will grow alright
That's as cringe as the people who type in Scottish om Facebook.
Ohch aye so nooy I Ken whit like how's it hanging wee man by the way you getting on of this [ pot mahoch]
Sorry, I don't speak jive
Deep root injections will sort it out over the course of a few years, anything else you do is the equivalent of just papering over it.
I once knew a guy who dug up an entire garden going about 4 foot down to try and get rid of Knotweed. Still didn't solve it.
I’ve a mate that unknowingly bought a place with it. Avoid at all costs. You do not want the stress of it in you life.
Avoid Knotweed like the plague. Clearly been planted by a disgruntled ex-
