The claim “THIS burns weeds in 1 day! They NEVER grow again” is a common gardening headline, but it is usually misleading. A weed can be killed quickly on the surface without being permanently eliminated.
What can kill weeds quickly?
- Boiling water: Can scorch leaves and kill small weeds, especially in cracks in paving, but deep roots may survive.
- Vinegar-based sprays: Can burn green leaves within a day, but many perennial weeds grow back from their roots.
- Salt mixtures: May kill plants, but they can also damage soil, harm nearby plants, and make areas difficult to grow in.
- Commercial weed killers: Some are designed to move into roots and provide longer-lasting control, but results depend on the product and the weed.
Why weeds come back
Many weeds survive because they have:
- Deep roots (such as taproots)
- Underground stems or runners
- Seeds already present in the soil
Burning the leaves does not always remove the plant’s ability to regrow.
More reliable long-term weed control
✅ Pull weeds out with as much root as possible
✅ Apply mulch to block sunlight
✅ Fill cracks in paving where weeds grow
✅ Keep lawns and garden beds healthy so weeds have less space to establish
If you mean a specific “secret” mixture from a video (for example vinegar, salt, dish soap, or something else), tell me the ingredients and I can explain whether it actually works and whether it may damage your garden.
