Claims that a homemade substance can “burn weeds in 1 day and they never grow again” are usually exaggerated. Many DIY weed killers can damage or kill the visible leaves, but they often do not permanently prevent regrowth because weed roots and seeds may remain alive.
What can kill weeds quickly?
Some common approaches:
- Boiling water: Can scorch small weeds growing in cracks, sidewalks, and driveways. It may kill the plant tissue it reaches, but deep roots can survive.
- Vinegar-based weed killers: High-strength horticultural vinegar can burn foliage quickly, especially on young weeds, but many perennial weeds can return from their roots.
- Manual removal: Pulling weeds out with as much of the root as possible is often more reliable for long-term control.
- Mulching: A thick layer of mulch can block sunlight and reduce new weed growth.
Why “never grow again” is unlikely
Weeds can come back because:
- Roots or underground stems remain alive
- Seeds already in the soil germinate later
- Wind, birds, animals, and nearby gardens bring in new seeds
For longer-lasting weed control
- Remove weeds before they flower and produce seeds
- Use mulch or ground cover plants to reduce empty soil space
- Improve lawn or garden density so weeds have fewer opportunities to establish
If you mean a specific viral recipe (for example salt, vinegar, baking soda, bleach, or another ingredient), tell me the ingredients and where you want to use it (lawn, driveway, garden beds), and I can explain whether it actually works and what risks it has.
