The claim “The best homemade weed killer: no poison (dries everything in 2 hours)” is misleading.Homemade weed killers can damage or kill weeds, but they are not harmless simply because they’re homemade.
A common recipe combines:
- White vinegar
- Salt
- Dish soap
Here’s what to know:
- Vinegar burns the leaves it contacts, especially on young weeds.
- Dish soap helps the mixture stick to the plant.
- Salt can kill plants, but it can also remain in the soil, making it difficult for other plants to grow.
Limitations
- Most homemade sprays only kill the above-ground parts of many weeds. Perennial weeds with deep roots often grow back.
- Results depend on the type of weed, weather, and vinegar strength. Claims that it “dries everything in 2 hours” are exaggerated—plants may wilt quickly, but complete control often takes longer or requires repeat treatments.
- These mixtures can also harm desirable plants if they come into contact with them.
Safer uses
Homemade vinegar-based weed killers are best reserved for areas such as:
- Driveways
- Sidewalk cracks
- Gravel paths
Avoid using salt-based mixtures in garden beds or lawns, as they can damage the soil and nearby plants.
In short, homemade weed killers can be effective for some weeds, but they are not universally safe, not always the “best” option, and they don’t reliably eliminate all weeds in just a couple of hours.
