Weeds sprout and regrow rapidly, especially between cobblestones and driveway slabs. If your driveway is overrun like mine once was, you'll appreciate a safe, effective solution.
I avoid commercial herbicides like Roundup due to their toxic chemicals, which harm health and the environment. Instead, I've perfected a chemical-free approach that's quick, reliable, and backed by years of hands-on gardening experience.
Here's my simple 3-step method to kill weeds and stop them from coming back:

Weeds pull out much easier once they're dead. Start by spraying a homemade, 100% natural weed killer directly on them.
For garden paths: Mix 100 g of salt and a small squirt of washing-up liquid in a spray bottle, then fill the rest with white vinegar. This potent blend dehydrates weeds effectively.
For larger areas like driveways, use a garden sprayer for efficiency. Combine 4 liters of white vinegar, 60 ml of washing-up liquid, and 500 g of Epsom salt (magnesium sulphate).

I've relied on these recipes for years—they're safe, inexpensive, and deliver professional results without synthetic additives.

Wait 2-3 days for the killer to take effect. The weeds will wilt and die, making removal effortless by hand.
The transformation is impressive: roots lift cleanly, leaving a tidy surface. While optional, pulling them immediately keeps things neat—I've done this countless times on my own property.

To keep weeds at bay, apply baking soda or cornmeal to cracks and joints where seeds settle.
Both inhibit germination effectively—my driveway has stayed weed-free for over a month. Cornmeal may attract ants occasionally, while baking soda starts white but dissolves naturally over time, becoming invisible yet still protective.
This method delivers a pristine, weed-free driveway quickly and sustainably—no toxic products needed.
For years, I hand-pulled weeds, only for them to return. Now, this routine keeps them gone. As a bonus, boiling water works well for spot treatments, but use caution to avoid burns.
