Use Salt

The best time to do this is during dry periods when the ground is not moist enough for plant growth. This will kill your weeds over time by desiccating them with salt.

Cornmeal, coffee grounds and eggshells

1. Cornmeal

2. Coffee grounds and eggshells

To get rid of your pesky weeds, try sprinkling coffee grounds and eggshells around the weed. The caffeine will kill the roots while the eggshells will cut through the surface leaving your grass intact and looking healthy as ever! This method is not as effective on larger patches but can work well on clover in smaller areas where you have paths or driveways.

Diatomaceous earth

What kills weeds permanently is sometimes the most natural option.

Hot water with soap

Soap bubbles alone do the trick on small patches, but we found success in a hot water bath with soap. This kills the weeds because it damages the cell walls that plants need for growth. But watch out—soap leaves a buildup on plants’ surfaces and roots, preventing their access to oxygen and, in turn, slowing down their growth. Pour dish soap into a spray bottle filled with hot water, then mist both sides of weeds before sliding fingers or an abrasive pad (coffee filters are effective) between leaves and stems to remove any soap residue.

Then kill large patches of weeds naturally. Combining vinegar with baking soda will help prevent new growth if sprayed onto cut edges of newly-deceased weeds after you pull them out of the ground.


Killing weeds is as easy as taking a walk on the old school side and using that brick or mortar. Use sandpaper to scrape weed off the sidewalk or street in large patches. They can’t come back if you take them all out at once, so get the shovel and chop ’em up. Problem solved.

These include honeybees, butterflies, and other insects that many of us enjoy seeing in our gardens and ecosystems as they help out with pollination.
