The first mow should be ½” shorter than than the usual mowing height to remove dormant grass and encourage the lawn to “wake up”.

Ohio grasses such as Kentucky Blue Grass (KGB), rye, and fescue should be mowed at 2.5-4” in height. This reduces lawn stress, diseases, and reduces weed growth. Only remove 1/3 of the grass blade height per mowing to reduce stress and disease.

To prevent winter diseases like snow mold, grass should be cut to 2” in height max.
