The headline “THIS burns weeds in 1 day! They NEVER grow again” is a common clickbait gardening claim. Some treatments can make weeds look dead within a day, but “never grow again” is usually not true because many weeds can regrow from roots, underground stems, or seeds already in the soil.
Common things behind this claim include:
- Vinegar: Can quickly scorch leaves, especially on young weeds, but often does not kill deep roots.
- Boiling water: Can kill the visible plant parts but may not stop established weeds from returning.
- Salt mixtures: Can kill plants, but they can also damage soil and prevent desirable plants from growing.
- Commercial herbicides: Some are designed to kill roots, but even they cannot prevent new weeds from sprouting later.
For more lasting weed control:
- Pull or dig out weeds and remove the roots.
- Use mulch or ground cover to block sunlight.
- Keep weeds from producing seeds.
- Use targeted weed-control products only as directed when needed.
A treatment may burn weeds quickly, but a guarantee that they will never return is not realistic.
