If you’re referring to a weed-killing product or a viral claim that “burns weeds in 1 day and they never grow again,” that wording is usually an exaggeration.
- Some herbicides can make weeds look dead within a day (especially contact herbicides), but the roots may survive and weeds can return.
- Long-term prevention usually requires either a systemic herbicide that moves into the roots, repeated treatment, or changing the conditions that allow weeds to grow (mulch, ground cover, removing roots, etc.).
- “Never grow again” is rarely true unless the area is permanently altered (for example, paving or using a suitable barrier).
If you mean a specific product or recipe, share its name or ingredients and I can help evaluate whether the claim is accurate.
