Here Are the Cheapest Ways to Kill Grass
1. Use a black plastic
Killing grass with plastic sheeting is more effective in the summer months. This method uses high temperatures to cause serious stress to the grass. When the temperatures are above 95°, grass experiences heat stress and dies.
Black plastic is a good option because it blocks light from reaching the lawn, making the grass lose its color and die.
2. Consider newspapers
The use of newspapers is another cheap method of killing grass. This method requires a large collection of newspapers to block all the light.
And because the wind can blow the newspapers, it is good to apply mulch as a final step.
Spread a layer of mulch about 6 inches to press the newspapers against the grass. Also, spray water over the area to make the grass rot faster.
