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.
Here are questions related to Killing Weeds With Vinegar.
When someone said to use vinegar for weeds, do they mean the white vinegar or not?
For weeds in general, I use 1 gallon of white vinegar, 2 cups of table salt, and 8 drops of dawn dish soap. Pour about 2 cups from the gallon of vinegar, set aside, add the salt, cover and shake until you no longer see the salt. Add the dawn and shake again. Pour into your sprayer for use. Take care when spraying as it will kill flowers too.
Add the 2 cups of vinegar to a hand sprayer add water to the top, plus about 4 drops of dawn. Now you have a good all purpose household cleaner.

|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?|

|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.|

|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.|

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.

Try using 10% vinegar. It's safer and works better. (09/01/2006)

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.

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)
