Vinegar can be effective in killing weeds if it's high in acetic acid.
Vinegar contains acetic acid, which has herbicidal properties and can damage or kill plants, including weeds. However, it is important to note that vinegar is a non-selective herbicide, meaning it can harm or kill any plant it comes into contact with, including desirable plants.
When using vinegar as a weed killer, it's best to apply it directly to the leaves and stems of the weeds on a sunny day. The higher the concentration of acetic acid in the vinegar, the more effective it will be in killing the weeds. Household vinegar typically contains about 5% acetic acid, but for stronger results, you can use horticultural vinegar with a higher acetic acid concentration.
Keep in mind that vinegar may not be as effective on established or deep-rooted weeds, and it might need multiple applications to completely eliminate them. Additionally, be cautious when using vinegar around desirable plants, as it can harm them too.
