Mixing vinegar and salt is a natural and effective way to kill weeds without harmful chemicals. This solution works by drawing moisture out of the weeds, effectively drying them out and preventing growth. To make this weed killer, simply combine vinegar, salt, and a bit of dish soap for improved effectiveness.
How to Mix Vinegar and Salt to Kill Weeds
What Ingredients Do You Need?
To create a homemade weed killer, you’ll need:
- Vinegar: Use white vinegar with at least 5% acetic acid for best results.
