The headline “THIS burns weeds in 1 day! They NEVER grow again” is mostly clickbait.
While some homemade or chemical weed killers can make weeds look dead quickly, almost no method guarantees that weeds will never grow again. Weeds return because many have deep roots, underground stems, or seeds already present in the soil.
Some common approaches:
- Boiling water: Can kill the leaves and shallow roots of some weeds, especially in cracks and pavement areas, but regrowth is possible.
- Vinegar-based sprays: Strong horticultural vinegar can burn foliage quickly, but it often does not kill deep roots, so perennial weeds may return.
- Salt mixtures: Can kill plants, but salt can damage soil, harm nearby plants, and make areas difficult to grow in.
- Commercial herbicides: Some work very effectively, but results depend on the weed species, product, timing, and correct application.
For longer-lasting weed control:
- Remove weeds with as much of the root system as possible.
- Use mulch to block sunlight and reduce new growth.
- Improve lawn or garden density so weeds have fewer opportunities to establish.
- Identify the weed first, since different weeds require different strategies.
Bottom line: A treatment may kill visible weeds in a day, but the claim that they will “never grow again” is unrealistic. Long-term control usually requires preventing regrowth, not just burning the leaves.
