The headline “THIS burns weeds in 1 day! They NEVER grow again” is almost certainly an exaggeration.
There is no homemade spray or household ingredient that reliably kills weeds in one day and prevents them from ever returning. Many weeds regrow from roots or seeds left in the soil.
What works for small weeds
Boiling water
- Effective for weeds growing in cracks in driveways or sidewalks.
- Can damage nearby plants, so use carefully.
Hand-pulling
- Most effective when the soil is moist.
- Remove as much of the root as possible to reduce regrowth.
Mulch
- A 2–4 inch (5–10 cm) layer of mulch helps block sunlight and suppress new weeds in garden beds.
About popular homemade weed killers
Many viral recipes use:
- White vinegar
- Salt
- Dish soap
These can burn the leaves of young weeds, but:
- Vinegar usually doesn’t kill deep roots of established perennial weeds.
- Salt can remain in the soil and make it difficult for desirable plants to grow, so it’s generally not recommended for garden beds.
- Dish soap mainly helps the mixture stick to leaves; it isn’t a weed killer by itself.
The best long-term approach
- Pull weeds before they produce seeds.
- Apply mulch around desirable plants.
- Fill cracks in patios or driveways where weeds repeatedly emerge.
- For persistent invasive weeds, targeted herbicides may be appropriate if used according to the product label.
