Will Vinegar Kill Poison Ivy?
Common white vinegar can be used to kill poison ivy, but its effectiveness may be reduced by the soil. Homeowners can combine white vinegar with salt to maximize its potency. Alternatively, use horticultural vinegar to kill poison ivy as it is more effective against poison ivy.
Using Vinegar to Kill Poison Ivy
Poison ivy is a nuisance. You would be best served to get rid of it as soon as it makes an appearance in your garden.
As annoying and harmful as poison ivy can be, many homeowners still prefer not to use artificial products to eliminate it. They would rather use household ingredients to remove that unwanted plant.
If you’ve talked to other homeowners about your poison ivy woes before, some of them may have suggested using vinegar to resolve your troubles.
So, is using vinegar against poison ivy idea a good idea?
Vinegar is indeed a useful tool for eliminating poison ivy. The acetic acid in the vinegar can destroy the cell membranes of the poison ivy and effectively kill it.
However, common white vinegar only contains 5 percent acetic acid. Because of that, it may not kill the poison ivy completely.
Furthermore, the soil supporting the poison ivy may also save it from destruction. The soil can protect the roots of the poison ivy by neutralizing the vinegar.
If you intend to use white vinegar on poison ivy, you have to make it more potent.
Killing Poison Ivy Using White Vinegar
Since white vinegar by itself may not be strong enough to kill poison ivy, you need to give it a boost with another household item.
Grab a pot and pour some vinegar in there. A half-gallon of vinegar should suffice, but you may need more based on your poison ivy situation.
Turn on the heat now and add about a half cup of salt to the white vinegar. Continue stirring the mixture until the salt is completely dissolved.
After the salt dissolves, remove it from the heat for the mixture to cool down first. Then, transfer the salt-vinegar mixture to a spray bottle and use that on the poison ivy.
Both vinegar and salt are potent weed killers.
Adding salt to the vinegar also allows the latter to work faster. The soil will not be able to protect the poison ivy’s roots anymore.
Using Horticultural Vinegar on Poison Ivy
The salt and vinegar mixture we discussed above should be enough to eliminate small bundles of poison ivy.
But what if you have a poison ivy overgrowth in the backyard? Can you still use white vinegar and salt to eliminate those pesky weeds?
If you’re dealing with a lot of poison ivy, the white vinegar and salt mixture may no longer suffice. You may need to use something stronger.
Horticultural vinegar could be the product you are looking for.
According to Oregon State University’s post, horticultural vinegar contains 20 percent acetic acid. It is four times more potent than the vinegar you probably have stored in your kitchen cupboard.
The poison ivy growing in your yard will have no chance of surviving if you spray it with horticultural vinegar.
Then again, the potency of horticultural vinegar can be a double-edged sword. Its high acetic acid content will kill the poison ivy for sure, but it can also harm you.
Homeowners are urged to be very careful when using horticultural vinegar for any reason.
You should wear protective gloves and goggles at a minimum before you handle the horticultural vinegar. It would also be a good idea to wear articles of clothing that can protect your exposed skin.
You can burn your skin or damage your eyes if you mishandle horticultural vinegar so exercise as much caution as possible.
Potential Risks of Using Vinegar to Kill Poison Ivy
Vinegar can be an effective tool for eliminating poison ivy, but using it does carry considerable risk for homeowners.
One downside you must be aware of is the fact that vinegar can destroy more than just the poison ivy. If any of the plants growing near the poison ivy are hit by the vinegar, they may also end up destroyed.
Using salt and vinegar together may also have long-term ramifications for your garden.
As the salt permeates the soil, it may prevent plants from settling in there for the foreseeable future. You may be unable to use that patch of land to grow plants.
Lastly, you have to be wary of how the vinegar may affect some of the insects that live in your garden. While some of those insects are pests that you want to remove, others are actively stimulating plant growth.
You risk killing them as well if you use vinegar on the poison ivy.
