Step 3: Allow the bleach to sit on the weeds for at least 30 minutes before rinsing it off. You can then either let the area dry or cover it with mulch. The weeds will die within a few days.

Note: If you’re concerned about damaging your sidewalk, you can test the bleach in a small area first. Apply the mixture to a small patch of weeds and wait 24 hours to see if there’s any damage. Or you can use a more diluted version by simply mixing up 1 part bleach to 10 parts water.

  • The best time to apply the solution is in the early morning or evening when the temperatures are cooler. Avoid using bleach on a windy day to prevent spreading to other plants.

When diluted, bleach acts as a herbicide, killing plants and weeds.
