How to Kill My Grass


A typical homeowner can have many reasons to kill their lawn. Maybe your lawn is in shambles, or maybe you want to put in a garden or flower bed where part of your lawn currently grows. To effectively do those things, you must kill off the existing grass. Grass can be killed with a non-selective herbicide like Roundup. One or two applications of the herbicide will effectively kill all the grass. Non-selective herbicide rapidly breaks down in the soil, so the area killed can be planted again immediately.

Step 1

Mix up the correct amount of non-selective herbicide concentrate and water and fill your pump-up sprayer. Read the bottle for the correct mixing ratios.

Step 2

Spray the grass you want to kill with your pump-up sprayer. Getting the grass blades moist is sufficient to kill them.

Step 3

Apply a second round of non-selective herbicide a week later to kill any remaining grass in the area that wasn't killed with the first application.

Tips and Warnings

  • Be careful with non-selective herbicide. It will kill any plant it comes in contact with, including desirable flowers, trees and shrubs. Don't spray when it's windy outside; this will reduce the chance of the spray getting where you don't want it to. Wear protective clothing, gloves and safety goggles when dispensing herbicides. They can be irritants to the skin and eyes.
