That’s almost certainly clickbait or exaggerated marketing, not a reliable gardening fact.
Weeds can be killed quickly, but the claim “burns weeds in 1 day and they NEVER grow again” is misleading for a few reasons:
What’s actually true
- You can burn or kill visible weed growth fast using methods like:
- boiling water
- vinegar-based sprays
- salt (not recommended long-term)
- flame weeders
- These methods may make weeds look dead within hours or a day.
What’s NOT true
- “They NEVER grow again” is unrealistic.
- Most weeds regrow from deep roots
- or seeds already in the soil
- Unless you remove or destroy the root system, weeds usually return.
Why these posts spread
They’re designed to:
- sound like a “miracle hack”
- get clicks (“See more”, “secret trick”)
- oversimplify real gardening problems
What actually works long-term
- Pulling weeds with roots (best manual method)
- Mulching to block sunlight
- Using proper herbicides if needed
- Regular maintenance (because weed seeds keep coming)
So yes—some methods can kill weeds quickly, but the “never grow again” part is just marketing hype, not science.
If you want, tell me what kind of weeds you have and I can suggest a method that actually works long-term for your situation.
