1️⃣ Vinegar, Salt & Dish Soap Weed Killer (The Classic Recipe) 🍋
This is the most popular homemade weed killer online — and for good reason. It’s powerful, fast, and incredibly simple.
How it works
- Vinegar (acetic acid) dries out the leaves
- Salt dehydrates the plant and soil
- Dish soap helps the solution stick to the leaves
Ingredients
- 1 gallon white vinegar (5% acidity works, higher is stronger)
- 1 cup salt
- 1 tablespoon dish soap (not detergent)
How to make it
- Pour the vinegar into a large container.
- Add the salt and stir until fully dissolved.
- Mix in the dish soap gently.
- Pour into a spray bottle or garden sprayer.
How to use it
- Spray directly onto the leaves
- Apply on a hot, sunny day
- Avoid windy conditions
- Do not spray soil you want to reuse for planting
🔥 Results: Most weeds wilt within hours and die within 24–48 hours.
