Vinegar is an excellent weed killer

b/c I doubt vinegar would kill things like couch grass.
Christian Graus Please read this if you don't understand the answer I've given you. If you're still stuck, ask me for more information.
Worth a try, I googled couch grass and it seems to be different in that it has a tap root like dandelions so might need repeated treatments. In a university study they used 20% acetic acid and it was 90% effective.

Hmm, thanks for the tip - i can't wait to try it on anything that survived the propane torch last Friday. :D

Ironically that's the reason why I found out about vinegar, I was searching for a weed torch, we have a *lot* of gravel trails to keep weed free but I was a bit worried about setting the place on fire, it's back in some heavy treed and jungly area.

You have a point. :) I was kinda psyched to tear into the swiffer and it does make a cool noise with it's battery and all but that would make far more sense. Cheers!

Cool! Three things he neglected to mention: 5% is a little weak: in the university tests they used 20% but I've tried 7% the strongest I could get and it works well, some plants are not outright killed by losing all their leaves but they can't survive without any leaves for very long so when they grow back you just spray it again, it *will* die eventually, the PH change caused by the vinegar is negligable if you are just spraying the leaves with a hand spray; if you are broad spraying everywhere then it will go down but in that same university test they found vinegar doesn't have a lasting effect and the ph went back to pre spray levels in a few weeks to a year in the most heavily dosed areas.

For long tap roots, an effective and safe method is to make a cut in the top of the root, exposing the "inside" of the the root, and pour some ordinary table salt on top, followed by a few drops of water. Effective, and just like the vinegar, a good solution if you have animals or small children around, when dedicated herbicides are a no-no.
Sounds like more work and though I see salt mentioned all the time with weeds I think people have forgotten the meaning behind the ancient phrase "salting the earth". Nothing will ever grow again if too much salt is put on some ground. I'm willing to bet that the dandelions that I sprayed and are now appearing dead will make a comeback from their tap root but I bet if I spray the new leaves a few more times there won't be any more life left in it. A taproot can't survive indefinitely without any leaves. I'll find out either way.

True, but the trick is to cut the root, and put the salt only on the root. It's the same with any non-specific herbicide - enough of it will kill anything. That's one of the advantages of the proprietary products - they target specific types of plants (lawn weedkillers for example, kill weeds but not grass).

No, it's not the same at all, salt *permanently* ensures nothing will *ever* grow where it's present in enough concentration.

For those who want a "green" solution to weeds that actually works I can confirm that white pickling vinegar (7% acetic acid) makes an amazing plant killer. Spray it on any leaf you want to kill on a hot sunny day and within 10 minutes it's starting to turn brown and shortly afterwards the leaves are completely dead (none took longer than overnight). It works by stripping off the waxy coating on leaves that prevents them from dehydrating too quickly. No need for expensive or potentially dangerous chemicals, just make sure it's at least 7% acetic acid (stronger would be better but not as available but "Pickling" vinegar is usually at least 7%) and put it in a cheap plastic spray bottle and you have a plant killer. It will kill almost any leaf you spray it on depending on how waxy they are some will be more resistant (that's why 20% would be even better) but it works great on dandelions, thistles, grass etc etc. For dandelions just spray the leaves and the center of the flower. Dandelions and others with a long tap root will need a subsequent application because it won't kill the root, just all the leaves, but as long as the leaves are dead the root will die in pretty short order. I'm going to hack a Swiffer WetJet mop so I can refill it with vinegar and use it's built in battery powered sprayer to do large areas conveniently (I have a lot of gravel trails in the back of our property that I want to keep vegetation free), the spray bottle gets tiresome after a while. There are commercial formulations based on vinegar now and they contain surfactants to make the liquid spread more evenly on the leaf and not bead up, I'm going to experiment with that as well, maybe dish soap or citrus based organic cleaners. Kinda makes you wonder why there are so many complex alternatives like Roundup when plain old vinegar works so well.

A neighbor told me about that earlier in the year, but his formula included dish detergent (I assume to help it stay on the leaves). I tried it, it worked, but it seemed to take a lot of vinegar, so I figured Round-Up would be more cost effective. I don't know about where you live, but this is the land of gravel yards. Ergo, need to cover a lot of area and don't want to leave anything alive. The idea of an old propane grill burner on a stick really appeals to me... :-D

I have about a kilometer of gravel trails throughout our property. The key thing with the vinegar is it has to be at least 7% (20 would be better but it's hard to find) and it has to be a dry hot day. Works great here even without the dish detergent but there's no doubt some weeds that are more resistant and need the higher percentage. I just use a fine spray on them so it's not very much at all per plant but whatever works.

I think it depends on where the weeds are. I remember being told how some weed killers (the feed'n'weed variety) work. The contain a growth hormone that broad leafed plants (typically weeds) can use, however the grass itself cannot. For the grass is a different formulation designed just to feed the grass. The weed is killed because it is forced to grow too quickly and it dies as a result.

Oh, come on now. I wouldn't say never - the Romans salted all (or at least got very good coverage) of Israel back in the first couple of centuries AD, and now they're a major exporter of fruits and flowers and all kinds of plant life. All you've got to do is wait a millennium or two. The drastic climate changes brought about by salting the land can be undone!
