This one's permanent. The salt sterilizes the soil, so only use it where you never want anything growing again, driveways, sidewalk cracks, gravel paths. If you're clearing a spot you plan to replant, skip the salt entirely and use straight vinegar with a teaspoon of dish soap instead. Reapply as needed on stubborn weeds, and always spray on a still day so it doesn't drift onto plants you love.
Homemade Weed Killer (Vinegar, Salt & Dish Soap)
The pantry combo that kills weeds for good, no Roundup required. Mix it, spray it, and watch your driveway cracks give up the fight.
Servings: 1 gallon
Cost: $3–$5
Equipment
- Garden sprayer
Ingredients
- 1 gallon white vinegar 5% acidity
- 1 cup table salt
- 1 teaspoon liquid dish soap
Instructions
- Pour the vinegar into a container larger than a gallon, so you've got room to shake.
- Add the salt, seal the lid, and shake until it mostly dissolves. It won't all the way, and that's fine.
- Stir in the dish soap.
- Pour the mixture into your garden sprayer.
- On a dry, sunny day, soak the weeds thoroughly, avoiding anything you want to keep.
- Let it sit. You'll see wilting within a few hours.
