How vinegar kills weeds<\/span><\/h2>
Vinegar’s active ingredient, acetic acid, kills weeds by dehydrating them. When acetic acid touches a plant, cell walls shatter, and moisture escapes the plant’s tissue. After a few hours, most plants show a decline. Within a day, many weeds shrivel up and die. <\/p>
Vinegar is a non-selective contact herbicide, and one of the best post-emergent herbicides<\/a>:<\/p>
- Contact herbicides<\/strong> can’t infiltrate a plant’s root system. Instead, they damage the parts they touch, like the stems and leaves. <\/li> <\/ul>
- Non-selective herbicides<\/strong> aren’t picky about which plants they pursue. Joe Neal, professor of weed science and extension specialist at North Carolina State, says, \u201cAny green plant that they contact will be injured or killed.\u201d<\/li>
- Post-emergent herbicides<\/strong> kill weeds after they sprout. Since vinegar dehydrates existing plants, it\u2019s a type of post-emergent herbicide<\/a>. Along with renting a goat<\/a>, it\u2019s one of the best natural weed killers.<\/li> <\/ul>
My tip: <\/strong>Vinegar doesn’t impact the soil for long. A few days after applying vinegar, new seedlings may sprout. Keep an eye on where you applied vinegar weed killer and reapply it as necessary.<\/p>

Amy Stenglein | Lawn Love<\/figcaption><\/figure> Although vinegar harms just about any plant, it controls some weed types<\/a> better than others. It’s most effective at killing young annual broadleaf weeds<\/a>, and least effective on mature perennial and grassy weeds<\/a>.<\/p>
Before applying vinegar weed killer, consider how well it controls the type of weed<\/a> in your yard:<\/p>
- Maturity:<\/strong> Since acetic acid kills with contact, it’s most deadly when it touches every leaf on a plant. Thus, vinegar weed killer is especially effective at eradicating young seedlings, and not as good at dealing with overgrown weeds<\/a>.<\/li> <\/ul>
- Leaf size:<\/strong> When comparing broadleaf vs. grassy weeds<\/a>, vinegar is better at killing the former. As the name suggests, broadleaf weeds have bigger leaves, giving acetic acid ample access to the large targets. <\/li> <\/ul>
