If you’re looking for a homemade weed killer, there are a few options that can work for certain situations. Keep in mind that “natural” doesn’t necessarily mean harmless—these methods can also damage desirable plants.
Homemade weed spray
Ingredients:
- 1 gallon (3.8 L) white vinegar (5% acetic acid)
- 1 tablespoon liquid dish soap
Directions:
- Mix the vinegar and dish soap in a spray bottle or garden sprayer.
- Spray directly onto the leaves of weeds on a dry, sunny day.
- Avoid getting the spray on nearby plants, as it can harm them too.
How it works:
- Vinegar burns the exposed foliage.
- Dish soap helps the solution stick to the leaves.
What to expect
- This works best on young, annual weeds.
- It usually does not kill the roots of established perennial weeds, so they often regrow and require repeated treatment.
- It’s most effective in warm, sunny weather.
Other non-chemical weed control methods
- Pull weeds by hand, especially after rain when the soil is soft.
- Apply 2–4 inches (5–10 cm) of mulch to suppress new weeds.
- Use landscape fabric in garden beds where appropriate.
- Hoe weeds while they’re small.
- For cracks in driveways or patios, repeated boiling water can kill top growth, though it may not eliminate deep roots.
A common online recipe combines vinegar, salt, and dish soap. While adding salt can make the spray more persistent, it can also remain in the soil and make it difficult for other plants to grow in that area for some time. For that reason, it’s generally best to avoid using salt in garden beds where you want future plant growth.
