Vinegar can be used as a natural herbicide to kill weeds in your vegetable garden. It is an effective, eco-friendly solution for managing unwanted plants without relying on synthetic chemicals. However, it’s important to use it properly to avoid harming your vegetables.
How Does Vinegar Kill Weeds?
Vinegar contains acetic acid, which is the active ingredient responsible for killing weeds. The acetic acid in vinegar draws moisture out of the plant’s leaves, causing them to dry out and die. This process is most effective on young, annual weeds.
What Type of Vinegar is Best for Killing Weeds?
- Household Vinegar: Contains around 5% acetic acid. It can be effective on small, young weeds.
- Horticultural Vinegar: Contains 20-30% acetic acid. This is more potent and effective on tougher weeds but should be used with caution.
How to Use Vinegar Safely in Your Vegetable Garden
- Choose the Right Day: Apply vinegar on a sunny, dry day. Sunlight enhances the drying effect of vinegar.
- Target the Weeds: Use a spray bottle or garden sprayer to apply vinegar directly onto the leaves of the weeds.
- Protect Your Vegetables: Avoid spraying vinegar on your vegetable plants as it can harm them just as it does weeds.
Tips for Using Vinegar Effectively
- Repeat Applications: For persistent weeds, multiple applications may be necessary.
- Combine with Salt or Soap: Adding a small amount of salt or dish soap can increase the effectiveness of vinegar.
Can Vinegar Harm My Soil?
Vinegar is generally safe for soil because it breaks down quickly. However, excessive use can lower soil pH. It’s best to use vinegar sparingly and avoid repeatedly applying it to the same area.

| Feature | Advantages | Disadvantages |
|---|---|---|
| Eco-Friendly | Safe for the environment | Can harm beneficial plants |
| Non-Toxic | Safe for pets and children | Can lower soil pH with overuse |
