The headline “THIS burns weeds in 1 day! They NEVER grow again” is almost certainly clickbait. There is no household spray or homemade mixture that reliably kills all weeds in one day and prevents them from ever returning.
Here’s what different methods actually do:
- Boiling water: Can quickly kill the leaves of young weeds, but deep roots often survive and regrow.
- Vinegar: Household vinegar (5% acetic acid) may burn the tops of small annual weeds on a sunny day, but it usually does not kill the roots of established or perennial weeds.
- Salt: Can kill plants, but it also remains in the soil and may prevent desirable plants from growing. It’s generally not recommended for gardens.
- Commercial herbicides: Some systemic herbicides move into the roots and can be effective on perennial weeds, but even these do not guarantee weeds will “never grow again.” New weeds can sprout from seeds or neighboring plants.
The most effective long-term approach is to:
- Pull or dig out the entire root system where practical.
- Apply mulch to suppress new weeds.
- Remove weeds before they produce seeds.
- Use an appropriate herbicide only if needed and according to the label instructions.
If you tell me what type of weed you’re trying to get rid of (or upload a photo), I can suggest the most effective method for that specific plant.
