Weedkiller

Hootsmon

I need some " industrial strength" weed killer shit for a largish area of garden I have ignored for years.... as a matter of fact they filmed some episodes of Tarzan here......I ain't fit enough tae weed hand by hand so a blitz is in order....

SBK is good stuff.

I bought Tesco's extra strong stuff recently not expecting much, it was about 4 quid. Weeds were gone after a week and haven't returned at all. This was in April.

Cut it down and cover with black polythene and weight and leave for a while

And if want a killer I'd get sort you dissolve in water then go over whole area

Befriend a tree surgeon.
They have much higher strength stuff than what you can buy at retail.

Salt water but don’t expect to grow anything there for a while.

Kill it with fire.

Get a Sheen X300 flame gun and go all Colonel Kilgore on it... (with paraffin rather than napalm, admittedly )

Less harmful to the environment than weedkiller, and *much* more fun .

Recently  bought this commercial strength weedkiller: https://www.amazon.co.uk/gp/product/B071GVC33M/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 and sprayer: https://www.amazon.co.uk/gp/product/B00RD0KTZQ/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

Works a treat and the sprayer makes it easy. Takes about a week or so before it takes effect.

For £50 I'll come and play guitar in your overgrown area for a few days - that should take care of any organic life in the vicinity.

Glyphosate based weedkiller will kill most weeds. Won't touch mare's tail though, you need some stuff that you can't buy as weedkiller anymore but you can still buy as a compost additive, can't remember the name of it off the top of my head.

Also, nothing really kills Japanese Knotweed (although injecting with glyphosate is the most effective method)

I got some stuff called Rosate for cheap online. Not tried it yet but the packaging is adorned with many environmental warnings and suggests you use a mask and gloves when handling it so I assume its the good stuff

Take off. Nuke em from orbit. Only way to be sure......

I would also echo what strtdv says - get the most concentrated form you can (cant remember the name, but it has a mostly blackish packaging I think) and use a dedicated sprayer (dirt cheap from ebay). Doesn't always work quickly but it *does* work.

you need a proper sprayer, an eye mask and breathing mask

I bought my first 5L from a farmer's merchant, but this year's one from ebay:

not tried this bottle yet, but trader has 185k feedback!

you need something like an 8L sprayer with a shoulder strap:

Yes, this. I got mine from a customer in the agriculture industry. It's powerful stuff.

We had knotweed in our land before we built our house. We had it treated but according to the people who did it, it's just a matter of time before it comes back.

Glyphoshate (aka Gallup/Roundup) is the most effective stuff you'll get retail.

Safest option is to apply it via watering can, and just be sensible with it. You used to be able to get ready mixed stuff that came in a kind of watering can type container, but I've not noticed that for a while.
It's actually pretty safe stuff. It will make you a bit ill if you drink it neat, but it's actually further down the poisonous scale than salt, unlike some of the other commercial alternatives.

Get yourself a couple of pigs, not only will they do the weeding, but they’ll give it a good dig over as well.
Once they’re done, just enjoy the sausages.

Hootsmon

What! they are gonna cook me sausages too?
