Headlines like “THIS burns weeds in 1 day! They NEVER grow again” are almost always exaggerated.
The truth is:
- Many homemade weed killers (such as vinegar, salt, or boiling water) can burn the leaves of weeds quickly, making them look dead within a day.
- However, very few treatments prevent weeds from ever returning, especially perennial weeds with deep roots or underground runners.
Common homemade weed killers
1. Boiling water
- Effective for weeds growing in sidewalk cracks or driveways.
- Can kill the above-ground parts and sometimes the roots of small weeds.
- Avoid using it near desirable plants.
2. Vinegar
- Household vinegar (5% acetic acid) can damage young weeds on sunny days.
- It mainly burns the leaves and often doesn’t kill established weeds with deep root systems.
3. Salt
- Salt can kill weeds, but it also remains in the soil and can prevent other plants from growing for a long time.
- It can also harm nearby vegetation and contaminate soil, so it’s generally not recommended for garden beds.
The best long-term approach
To reduce weeds over time:
- Pull weeds before they produce seeds.
- Apply mulch around garden plants.
- Fill cracks in driveways and paths.
- Use an appropriate herbicide according to the label if needed for persistent weeds.
No product or homemade mixture can honestly promise that weeds will “never grow again.” New weeds can emerge from seeds carried by wind, birds, or existing roots.
If you tell me where the weeds are (lawn, gravel driveway, patio, vegetable garden, flower bed, etc.), I can suggest the most effective and safest way to get rid of them.
