How to Kill Grass With Plastic
- 1). Decide how much area of the lawn to kill. Are you killing the grass to redo the lawn or do you just want to start a small garden? Plan carefully and map out the area so you don't end up killing more grass than you want to.
- 2). Measure the area where the grass will be killed. This will help you buy the right amount of plastic.
- 3). Purchase heavy plastic black or clear plastic. This will block out light in addition to smothering grass. Plastic about 1 or 2 ml thick will work best as it won't reflect as much sun as the thicker plastics will.
- 4). Mow the grass you want to kill and cut it very close. Set your lawnmower blade to the shortest available height.
- 5). Level the area. Rake it and remove any large rocks or dirt clods.
- 6). Water the soil. Make sure it is damp but not soaking. The wet soil will conduct heat better than dry soil.
- 7). Cover area with plastic. Anchor the edges with rocks or soil.
- 8). Leave the plastic on for one to two months in the spring or summer. In the fall or winter, leave it on for up to three months.
