That claim is almost certainly an exaggeration.If you’re referring to a video or headline that says “This burns weeds in 1 day! They NEVER grow again”, here’s the reality:
- Many herbicides can cause weeds to wilt or brown within 24 hours, but visible effects often take several days.
- No weed killer can truthfully guarantee weeds will “never grow again.” New weeds can sprout from seeds already in the soil, and some perennial weeds can regrow from surviving roots or rhizomes.
- Methods like boiling water, vinegar, salt, or flame weeding may quickly burn the tops of weeds, but they often don’t kill the entire root system, especially for deep-rooted perennial weeds.
- Systemic herbicides can kill the whole plant more effectively, but even then, they don’t permanently prevent future weeds from appearing.
If you saw this as a social media post or advertisement, it’s best to treat the “never grow again” part as marketing language rather than a literal claim.
If you meant a specific product or method, tell me its name or upload the image/video, and I can explain how well it actually works.
