We've used vinegar for killing weeds around the garden, for several years now. It's a great way to get rid of weeds in cracks in cement or in a paved driveway. You can pour it on directly from the jug or put it in a spray bottle (use full strength). Just a word of warning, if you don't want it to die, then don't go near it with the vinegar. If using in a flower garden, be careful around the plants you want to keep. The vinegar will leach to the other plants through the roots and kill them, so it may be better to pull these by hand.
Hope this helps! Good luck!
The higher the acidity percentage in the vinegar, the better it works.
Put straight vinegar into a cheap garden sprayer ($12) and spray this onto your weeds. You can also pour the vinegar right on to the soil to kill the roots and stop everything from growing there in the future. If you heat Vinegar up, it works even better. You can also buy a special vinegar with a stronger acid content at most plant nurseries that works even better!
If you want a temporary week killer and don't want to stop everything from growing, just pour boiling water on to the area. It's easiest to use a propane camping stove and boil your water outside. Use a camping coffee pot with a handle and a pouring-spout if you have one. Be careful that the steam doesn't splash back and scald you!
Use pickling vinegar instead of regular white or malt vinegar since it contains 7% acetic acid and not the usual 5%. The ratio of 1 teaspoon (5 millilitres) of liquid washing soap to 1 gallon (4 Litres) pickling vinegar is fine.

When someone said to use vinegar for weeds, do they mean the white vinegar or not?
It is the white vinegar. Be careful though - it is not selective at all. Any plant you get vinegar on, is going to be cooked by the vinegar!
White vinegar from your grocer. In my area it sells for about $2.40 per gallon.
I like using the white vinegar for weeds.
What ratio of vinegar and orange oil would you use to kill weeds?
Hardiness Zone: 9a
Spraying straight vinegar on weeds kills them; be sure to do only when the wind is not blowing!
You can also use boiling water to kill weeds.
I don't use Orange Oil, I just use full strength Vinegar, it cheap and work good. The only thing I might change would be adding something to thicken it so it doesn't run off, maybe cornstarch or something.
What kind of vinegar do you use to get rid of the grass in your driveway? Thx.
By L J from NPN, VA
Use a distilled white vinegar with a 15%-20% acetic level, the higher the level the better it will work. Spray it after the dew is gone and it should kill them in a few days. Be careful not to spray them on any other plants because it will kill them as well. :)
I buy the cheapest white vinegar I can find! To one gallon of vinegar, add a cup of salt and two tablespoons of dish detergent. The dish detergent acts as a sticker, making the vinegar stick to the plants leaves, better. Don't get this on anything you don't want to kill! It's best to spray the plants, during the hottest part of the day, when the sun is shining on the plants.
How do I make and use vinegar weed killer?
By Glenda from Winfield, MO
I used it when I lived in Louisiana & had fairly good luck. On a bright sunny day, I would spray full strength white vinegar on weeds & grass growing in places I didn't want it growing (like a small crack I had in the driveway). It took a few days to work. It won't work on huge patches, just strays and small clumps.
I remember reading something about this. It was mentioned to use on moss on sidewalks, driveways, etc. instead of harsh bleach. They used it in a garden sprayer. I was thinking of trying it myself this spring also. Still a little to rainy here in Oregon. If it works good, I'll try it again at half strength and cut it again if that works to.

When too much salt gets into the soil, whether it's Epsom salt or a build up of fertilizer salts, water is drawn out of a plant's roots instead of flowing into them. This is normally referred to as "burning", but actually the plant is becoming severely (or fatally) dehydrated. The plant's leaves and stems start to shrivel and turn brown and leaves may mutate from chloride toxicity. The best way to remedy soil containing excess salts is to remove the contaminated soil and amend it with healthy, nutrient-rich soil. For the amount of salt used by most gardeners in homemade tonics, the area can probably be considered "recovered" as soon as it's refreshed with some nutrient-rich soil.
Vinegar is a weak acid and when applied to the soil, it lowers the pH. Changing the pH too quickly can damage or even kill plants by altering their roots ability to absorb water and minerals. Fortunately, because vinegar is a weak acid, it degrades in water and doesn't bioaccumulate (stay in the environment). After flushing the soil with water, you can expect the pH to return to normal within 48-72 hours.
Very few plants will survive a dose of salt and/or vinegar. The only way I know of getting rid of it is to leach it out by regular watering. How effective this will be depends on what lies below the top soil; if its clay for e.g. then the remedy may not work - you may have to remove the top soil altogether. If its a well draining subsoil i.e. sandy then you should have some success - I hope. Also try a neutralising treatment to adjust the ph.
Salt kills plants. Dont use rock salt on your sidewalks. Only use plants near a roadway that can survive salt spread to prevent icing during the winter.
I'd try watering the effected plants heavily to try to wash the salts from the soil.
Having just experienced Katrina I can certainly attest to the fact that salt kills many things. We lost most all of our grass after everything was submerged by the Gulf of Mexico and were left with pretty much nothing but nasty weeds. Apparently weeds can thrive in salt! It has been a lot of work to get the grass back. And, while some of our shrubs and plants survived, a lot, like my precious azaleas, didn't make it.
If you spray vinegar ''at what rate?" will you be able to grow other plants in the same area? Does the vinegar sterilize the ground or how long will it keep weeds from reappearing?
I sprayed some moss with 100% vinegar and it killed the moss. It also killed the grass that abutted the moss. That was about 4 weeks ago and the areas that I sprayed have not turned green. So, it will be some time before any grass grows in those areas.When the weather turns better I will put down some lime in those areas to see if that helps the grass grow again.
Vinegar is a great weed killer, even better with dishsoap in it (the soap acts like a bonding agent) It will kill anything.
But unfortunately it changes the soil so that nothing will grow there after it has been used. Bleach is better 50/50- it doesnt hurt the soil and doesn't harm the environment. It dissipates after about 12 hours.
Although found this...Bleach, or sodium hypochlorite, has a pH of around 11, which means it can raise the pH of your soil, and this may damage valuable plants. Application of bleach to kill weeds also adds sodium to the soil, and this can make it difficult to grow plants in areas of your landscape treated with bleach. Vinegar, on the other hand, is a natural weed killer that does not negatively affect the soil. http://homeguid negar-42435.html So personally I'd stick with the vinegar if you think you want to grow something there later.
Will using vinegar to destroy grass and weeds between bricks harm newly planted trees?

How do I use vinegar to kill weeds in my lawn?

Just pour it straight on the weeds, but try not to get the grass or flowers, it will kill them too. (Pour in a small stream if possible). (06/15/2010)
I've tried using vinegar, but our weeds just laugh at it. :-( (06/15/2010)
Can you use vinegar to kill weeds? I need an inexpensive remedy to kill weeds.

By gperz from Old Saybrook, CT
Yes, you can! The very best vinegar to use is the stronger type you purchase at plant nurseries. It has a stronger acid concentration, but regular vinegar will also work (any type) and if you heat it up it works even better. Another thing that will work for one season is plain old boiling water.

Vinegar is non-selective, meaning it will kill anything it comes into contact with. This is usually limited to the above ground growth on a plant, which is why repeated applications are often necessary to completely kill weeds. How much damage a "desirable" plant sustains from contact with vinegar depends entirely on the amount of its exposure to it.
The reason using vinegar is so popular is because it's inexpensive. It also doesn't have any permanent negative long-term effects on the soil, although it does alter its ability to support growth in the short term. The distilled vinegar commonly found in grocery stores is usually a weak concentration (5 %), so it's considered safe for use around children and pets.
Higher concentrations of vinegar (20%) are available at some home or garden centers, but they can cause eye and skin irritation and should be used with extreme caution. I don't know of any "earth-friendly" chemicals that work on weeds without also harming grass and desirable plants.
Surrounding weeds with a coffee can (bottom and top removed) or another type of barrier will prevent the vinegar from drifting onto desirable plants while your spraying. You can "paint" vinegar on individual weeds to avoid damaging grass. To prevent weeds from emerging on your lawn while simultaneously fertilizing it, try to time an application of corn gluten meal to coincide with emerging weeds.
Hormoban will kill weeds but not the surrounding grass and plants. (07/10/2006)
20% vinegar is dangerous - it burns skin and eyes.

|I need to know what percentage is used to kill weeds with vinegar and water. I still want to grow some plants at a later time. How much should they be saturated?|
Hardiness Zone: 4a
|Killing Weeds With Vinegar||06/22/2006|
|When I spray the sidewalk cracks and such I use straight vinegar but be sure not to get it on things you want to live. Saturate welll as to get the roots, the weeds will turn brown and die. In a couple days you just pluck the brown above ground, if you see new sprouts then the root wasn't penetrated and you simply repeat the process.|
|Killing Weeds With Vinegar||06/24/2006|
|You need 20%. I used 5% and it killed dandelions when it was straight. I've never been able to find 20%, I was told you could get it at the garden centers.|
