That headline is almost certainly an exaggeration.
The reality about killing weeds
Many substances can make weeds wilt or die quickly, including:
- Vinegar-based weed killers
- Boiling water
- Commercial herbicides
- Salt solutions
However, “they never grow again” is rarely true.
Why weeds come back
- Many weeds have deep roots or underground stems.
- Some produce seeds that remain viable in the soil for years.
- A product may kill the visible leaves while the root survives and regrows.
Common “miracle” remedies
You may see claims about:
- Vinegar
- Salt
- Dish soap mixtures
These can damage or kill some weeds, especially young ones, but they can also:
- Harm nearby plants
- Damage soil if used excessively (especially salt)
- Require repeated applications
What works best
The most effective method depends on the weed:
- Hand-pulling (including the root) for small infestations
- Mulching to block sunlight
- Targeted herbicides for persistent weeds
- Repeated treatment of perennial weeds
Bottom line
A product or homemade mixture may burn weeds within a day, but claims that weeds will “never grow again” should be viewed skeptically. Long-term weed control usually requires removing roots, preventing reseeding, or repeated management.
If you tell me what “THIS” is (the ingredient or product in the headline), I can explain whether it actually works and what the evidence shows.
