I used some stuff from a farmer friend, that killed everything, it was called "pastor" by
Dow Corning, dunno if you have to be a farmer to use/buy it though.

Ordered some of this yesterday. How safe is it to use on weeds around the base of trees?

I've found brick & mortar acid to be very effective this spring after accidentally spilling some on some weeds a few weeks back. It seems to be a 28% hydrochloric acid mix & just burns them to a crisp - no sign of them coming back either

Tried this 2 weeks ago before I pressure washed my block paved drive. Nothing living there now :-)

Whats the best mix i.e spoonfuls to litres of water?

Used this, very good.
Not spoonfuls unfortunately. 1kg to 5litres of water.
Doesn't go far tho.

who needs weed-killer? I've just bought one of these puppies to kill stuff with...



I've got ammonium-sulphamate but I've also got inquisitive cats...

With ground elder, crop it and eat it. Cooks just like spinach. Can also be used as a salad leaf.

I've just moved house and am in the process of sorting the gardens out. Have a huge infestation of ground elder and it's spreading.

Off the shelf Glyphosate is killing it slower than it's spreading. There is nothing in the area that I want to keep so any suggestions would be welcome. Google has suggested that it's basically a nightmare.

I can't eat that much salad!

Use something like Resolva, that has a contact herbicide (Diquat), and a root herbicide (plain old Glyphosphate again). Use a sprayer or watering can, but if it's Ivy then add the Resolva AFTER you fill it with water. Then add a good dose of fairy liquid - the waxy nature of Ivy means the stuff tends to run off, adding Fairy makes it stick for long enough to be absorbed.

I've just got some weeds coming up where the tarmac drive edges meet the walls. Also have family member with a drive that has gravel down the middles of parallel laid slabs and that is just full of grass/weeds. The idea is to just kill everything, forever.

Salt, and loads of it. Roadsalt is best as it just keeps on dissolving for bloody ages.
But a good line of Saxa poured in, then lightly dampemened, has kept my drive weed free for ages.

Poor weeds, they're simply plants that people don't like.

I found the chemicals barely had any effect against ground elder. It's a bit mandraulic, but the only thing I've found that really tames it regular strimming.

Or brick acid.

That's pretty much the definition of a weed. If you wanted to grow a field of dandelions and a rose sprang up in the middle, the rose would be the weed...

I wouldn't, not if you want the trees to be unharmed.

[Agrispeed]

Acid will only burn the top of the weed off, hence why it is quick acting . It was sprayed on spud crops for years as it burnt the tops off but didn't damage anything underground (killing spuds before harvesting is how you get set skins).

Glyphosate works more slowly but travels within the plant and kills off its roots, thereby hopefully stopping any re-growth.

I wouldn't advise the use of any agricultural chemicals as they are stronger and don't have room for error built in. Gardeners weedkillers have a dhead margin built in to stop them being dangerous if spilt, inhaled etc. If you make a mistake with a agricultural version you can be in pretty big trouble as they are much more concentrated.

You can get pre-emergence herbicides for agricultural use, which stop seeds germinating until the ground is disturbed. You might be able to possibly get a domestic version?

There was propachlor, but long gone now.

nisure yet but it's done a fine job of turning a st load of unwanted foliage in the middle of this drive a very unhealthy shade of light yellow.

Can't post pic off my phone.... Hang on

would suggest it's definitely not going to fell a tree, unless you soak the ground with a few thousand litres of the stuff.

[Patrick Bateman]

Is there a combined weedkiller that's fast acting and kills the root?

The Weedol Rootkill Plus seems to take a fair while for the weed to die off, by which time there are new weeds growing anyway so there's always something there without regular attention.

I've just sprayed a load of the weeds with the fast acting Weedol 2 I'd had for ages but never used, not sure how stubborn they'll be.

[Timmy40]

Well I can report that the Japanese knotweed I fed petrol to by pouring it into the stem is all very, very, very dead.

It works amazingly well. Finally ridded myself of herb robert. bd stuff is impervious to glyphosate and spreads like cheap margarine.
