How Tall
To Cut Your Grass During A Drought
By JUSTO ALVAREZ
Experts recommend infrequently trimming the lawn and keeping the grass as high as four inches during dry seasons to ensure your turf can withstand them much better.
Lawn Dawg's corporate agronomist Bob Dann told HGTV, "A height of 3 to 4 inches will create a deeper root system that will pull more water from deep in the soil."
Keeping your lawn longer also helps conserve water. Since longer grass will keep the soil cooler, you won't have to use as much water to keep the lawn healthy during a drought.
However, if your grass has already entered a dormant stage, experts recommend stopping cutting altogether to put the least amount of stress possible on your lawn.
To know if your brown lawn is dead or dormant, simply tug on the grass. Dead grass will result in the uprooting of the blades, whereas dormant grass
will remain in the ground.
