Are we facing a knot weed epidemic?!

Yeah, sounds like bindweed, rather than knotweed!
One method of attack is to unravel it as much as you can and place the stems into plastic sandwich bags of weak glyphosate solution (like 25% - 50% of the recommended mix)
The root structure is fragile and breaks up easily, but each fragment can grow a plant, the glyphosate will kill each root section, but if there are tens or hundreds of sections..

As above, it sounds like bindweed, not knotweed..... (you better hope it's not knotweed anyway!!)

My neighbour had loads of this and it kept creeping through and under my fence and all over my block paving and garage. I doused it with a 6 month path clear weed killer every day for a week, during all this sunshine. It's all brown and dead now, along with a few thistles and other weeds that had grown. Seems to have done the trick. I just hope it doesn't all grow back in a hurry.

Japanese knotweed, when mature, has red bamboo like stems and heart shaped leaves. It is nasty insidious stuff.

And there are some of the flowers.

Here is some bindweed. It is a pain in the arse but not as bad.
If it is knotweed get in touch with your Local Authority, there are very strict regulations regarding its disposal and strict penalties if not adhered to.
(Though to be honest the description of flowers sounds like bind weed.

Hedge bindweed (the bigger flowers/leaves) tends to spread mostly (but not always) by quite shallow roots, so if you put in a polythene root barrier to say 3ft, you should be able to gradually eliminate it from your garden. It responds quite well to weedkiller and constant pulling up.
Field bindweed (smaller leaves/flowers) nearly always has exceptionally deep roots (several metres) and is very difficult to eliminate, if you weedkiller the top, it severs the poisoned part very quickly from the rest of the root network. The war of attrition is long and hard.

yep..bind weed.....I'm on year 7 of my war against it...and I'm winning despite having a large field next door which is covered in the stuff....and I'm winning....sort of !
Responds well to glyophosphate...and important after you killed it NOT to put it in your compost ! Also try and dig down as deep as possible to remove roots. Start of the year is always a challenge and we make a game out of it with my son....weekend walk arounds to "Spot the nasty plant"......grows fast !

Funny how every weed is automatically 'knotweed' these days, even if it's clearly a tree!
Real knotweed has asbestos in it of course.
I think Knotweed is the new Asbestos.Real knotweed has asbestos in it of course.
5-10 years ago, Asbestos was the 'kiss of death' with regards to property; insurers, Mortgage companies etc all ran a mile at any suggestion of the presence of it, but nowadays there are procedures in place for dealing with it and it's just one of these things.
Knotweed is a right pain, but it can be dealt with.
You can deal with knotweed with a root and stump killer. We had it 7-8 foot tall with 1" diameter stems in a neighbours parking area. I cut a knotch into the stem about 2 foot up and drained a little of the fluid. Then using a syringe I injected he root and stump killer in. 90% reduction in the 1st year and repeat treatments for 2 more years on anything that came back ( very weak and spindly) seems to have cleared it.

We have bindweed coming from next door. Our garden isn't being worked on for another year at least so I'm trying to keep it in check but the bindweed is complicating this.
Is glysophate effective on it?
Yes — just unwind it & lay it down on the ground, away from anything you want to keep & give it the treatment. It may take a few weeks — but trying to dig it out really isn't an effective option. The tiniest piece of root left behind will regrow.Is glysophate effective on it?
