Homemade Vinegar-Based Herbicide

Ingredients

• 1 liter white vinegar (5% acetic acid or higher)

• 1 tablespoon dish soap

• 1 tablespoon salt (optional, for stronger effect)

Instructions

1. Pour the vinegar into a spray bottle or garden sprayer.

2. Add the dish soap and gently mix (avoid creating too much foam).

3. Add salt if using, and stir until dissolved.

4. Spray directly onto the leaves of weeds on a dry, sunny day.

5. Avoid spraying on plants you want to keep, as this mixture is non-selective.

How It Works

• Vinegar dries out and damages plant tissues.

• Dish soap helps the solution stick to leaves.

• Salt can enhance the drying effect and prevent regrowth (but may affect soil quality if overused).

Tips for Best Results

• Apply during hot, sunny weather for maximum effectiveness.

• Target young weeds; older plants may need repeated applications.

• Reapply if it rains within 24 hours.

• Use carefully around garden plants and soil you want to preserve.

Important Notes

• This solution kills most plants it touches, not just weeds.

• It doesn’t usually kill roots completely, so some weeds may regrow.

• Avoid excessive salt use, as it can make soil less suitable for future planting.
