Why This Trick Is So Effective
No chemicals No gloves or tools No waiting days for results Safe for driveways, sidewalks, and patio cracks Costs almost nothing
Gardeners have used this method for generations, especially before commercial weed killers existed.
Where This Works Best
This trick is ideal for:
- Sidewalk cracks
- Driveways
- Patio stones
- Garden paths
It’s not recommended for lawns or garden beds, since boiling water kills any plant it touches.
Bonus Tip From Grandpa
For stubborn weeds, repeat the process once more after a few days. Most weeds won’t survive a second hit.
The Bottom Line
Sometimes the simplest solutions are the best. This old trick proves you don’t need expensive products or hours of hard work to keep weeds under control — just a little hot water and a few minutes of your time.
