Claims like “this burns weeds in 1 day and they never grow again” are usually exaggerated. There is no simple household spray that permanently prevents all weeds forever — many weeds regrow from roots, seeds, or underground stems.
What actually works depends on the situation:
For killing existing weeds quickly
- Boiling water: Works well on weeds growing in cracks (driveways, patios). It kills the above-ground plant, but deep roots may survive.
- Hand pulling with the root removed: Best for long-term control in gardens.
- Commercial herbicides: Some work within hours to days, but they must be used carefully and according to the label.
For preventing weeds from coming back
- Mulch (2–4 inches): Blocks sunlight and suppresses new growth.
- Landscape fabric (where appropriate): Helps under paths and decorative areas.
- Regular removal before seeds form: Reduces future weed problems.
Be cautious with viral “weed killer” recipes containing things like strong acids, excessive salt, or harsh chemicals — they can damage soil, harm nearby plants, and create runoff problems.
If you mean a specific product or recipe from a video (“THIS burns weeds…”), share its name or ingredients and I can help check whether it actually works and whether it’s safe to use.
