They are like triffids and seem to be able to multiply for sport. Less roots does mean that once they are gone they should be easier to prevent from coming back though! If you get my meaning.

A bramble will grow at least 3-4 meters long and root so you sound like you're lucky. The knotweed could be a harder critter to get rid of though.

persist with the knotweed when it grows again ,and again and well you get the picture .you can win if you outlast it .
bramble runners can be awesome long ,better than roots though .

just finished clearing it all and it loooks likethe roots are all inside a ( say it quietly so cadaw dont hear me) dry stome wall that used to be part of a listed circular toilet ( apparently about 400 years old). i cant get in to dig out the roots as it has collapsed inwards and the pub next door has padlocked up the other access..
oh well, i will just have to keep beating it back and pulling it up where i can..

Fire!
A flame gun which can be applied every couple of weeks to the new green growth will defeat it on your side of the wall eventually.

The wall should be able to withstand the heat for longer than the brambles. Just don't heat the rock to red hot and avoid cold water hitting the stone after you have heated it. Fire and cold water was an iron age technique for smashing rocks and shaping them.

Note: even after you have cleared your side, if it is able to grow unhindered on the other side of the wall it will never be killed off.

The alternative is a systemic poison which will kill the brambles back to the root.

Flame gun only needs to wilt the leaves/stems, not to blast them completely. You may need to do this a few times with brambles. It works not by burning the foliage, but just by collapsing the cell structure of the leaves / stems.

Saw a tractor driven flame weeder for use on commercial organic carrot fields yesterday : impressive but rather expensive to hire in !
Flamer the width of a 4-row wide carrot drill, in protective housing, with a row of tiny chain harrows on the back to disturb the weed seedling roots. Being done a couple of times before carrot seed sowing in order to create a 'stale seedbed'.

Stale seedbed = creating a fine tilth for your seedbed but not sowing; leaving it until the first crop of weeds emerge, hoeing or whatever to get rid of weed; repeating again to catch the second weed crop, and only then sowing.

Brilliant Dave, Thanks.

I poured parafin over mine last month and set the b*ggers on fire (we have loads of bramble here) which seems to have done the trick for now but:
a) It was a waste of parafin &
b) It set fire to most of the grass nearbye - silly me

The heat gun idea is most certainly the first thing I will go for when the damned things start to re-appear. Much more of a controlled approach.

Good post!

<end senior moment>

<reads word on tip of tongue>

Blowlamp.

That was the word I was trying to think of!
Flame Gun/Bitumen Torch/Heat gun

and Blowtorch!

I have a small gas unit. Cost a couple of pounds from Netto.
Gas canister is small to large (1 to 5) from camping or DIY stores

If you get one with the paint stripper attachment, then you get a wide strip of flame rather than a point.

When I wanted to clean the allotment I used a large propane tank with the flame gun from flat roof repair. I allowed the heat to bake off the slug eggs and seeds, slightly more than was necessary to just kill off the plants. But gil was correct that you can kill off the leaves quite quickly, my warning was that there is such a thing as too much heat on stone.

Yes, you can, and its rather like rhubarb. Take the leaves off young shoots and stew down with sugar. Great stuff.

When you're clearing it, be very, very careful. Drop any and it can root.

Other than boiling it to make wine, whats the best way of disposing of the stuff once you've cleared it?

Aren't there restrictions on how you dispose of knotweed? I think you can't take it to landfill? Maybe the enviroment agency have some advice.

I tried just wilting the weeds on my patio with the flame gume, and now it has rained (at last!) the things are looking as healthy as ever, so you do have burn 'em. Mind you, it is couch grass, so it might be exceptionally tough stuff.
