How to Make Super Effective Homemade Weed Killer

1. Pour the vinegar into a spray bottle or large container.

2. Add the salt and stir or shake well to completely dissolve it. This step is essential—salt acts as a desiccant, drying out the weed roots.

3. Add the dish soap. It works as a surfactant, helping the mixture stick to the leaves and enhancing the effectiveness of the vinegar and salt.

4. Transfer the solution to a spray bottle or manual sprayer. Seal tightly and shake before each use.

5. Apply directly to weeds, preferably on sunny, windless days. Spray only the plants you want to eliminate—avoid contact with desired vegetation.

Recommendations

• If it rains within 24 hours of application, reapply the solution.

• Visible results usually appear within a few hours, and full effect is seen in 24–48 hours.

• Apply when the plants are dry, ideally in the morning or at midday, for best results.

• Do not use on lawns or near cultivated plants, as this solution can harm any plant it touches or seeps into.

• Store leftover solution in a closed container, away from heat and direct sunlight. Shake well before each use.

• You can double or reduce the recipe quantities, maintaining the same proportions.

• If using coarse salt, allow more time for it to dissolve fully. Stir well to ensure proper mixing.
