Can I use vinegar on weeds growing in gravel or pavement? Yes, vinegar can be an effective and natural solution for killing weeds growing in gravel or pavement. It acts as a non-selective herbicide, meaning it can kill most plants it comes into contact with. To use vinegar effectively, apply it directly to the weeds on a sunny day, ensuring thorough coverage for the best results.
How Does Vinegar Kill Weeds?
Vinegar contains acetic acid, which is the active ingredient responsible for killing weeds. When applied, the acetic acid draws moisture out of the plant, causing it to dry out and die. This process is particularly effective on young, small weeds that have not yet developed deep root systems.
-
Acetic Acid Concentration: Household vinegar typically contains around 5% acetic acid, which can be effective on young weeds. For tougher weeds, you may need a horticultural vinegar with a higher concentration (10-20% acetic acid).
-
Application Method: Use a spray bottle or garden sprayer for even coverage. Apply the vinegar directly to the leaves of the weeds, avoiding any desirable plants.
When is the Best Time to Apply Vinegar to Weeds?
Timing is crucial when using vinegar as a weed killer. Here are some tips for optimal results:
-
Weather Conditions: Apply on a warm, sunny day. Sunlight enhances the effectiveness of vinegar by accelerating the drying process.
-
Time of Day: Morning applications are ideal, allowing the sun to work throughout the day.
-
Seasonal Considerations: Early spring and summer are the best times to tackle weeds, as they are typically smaller and more vulnerable.
Pros and Cons of Using Vinegar on Weeds

|---|---|---|
| Effectiveness | Natural and non-toxic | Less effective on mature, deep-rooted weeds |
| Environmental Impact | Safe for the environment | Can harm soil health with repeated use |
| Ease of Use | Simple application with household items | Requires multiple applications for tough weeds |
Practical Tips for Using Vinegar Safely
To ensure that you use vinegar safely and effectively, consider these practical tips:
-
Protect Surrounding Plants: Use a piece of cardboard or plastic to shield desirable plants from spray drift.
-
Wear Protective Gear: Use gloves and eye protection to avoid irritation from vinegar splashes.
-
Reapplication: Tough weeds may require multiple applications. Wait a few days between treatments to assess effectiveness.
