One of the most common lawn care mistakes homeowners make is cutting their grass too short. While a freshly cut lawn may look tidy at first, mowing too low can weaken the turf and create ideal conditions for weeds to take over.
In Michigan, most residential lawns are made up of cool-season grasses, which perform best when they are kept slightly taller.
Understanding the proper mowing height can dramatically improve the health and appearance of your lawn.
Ideal Mowing Height for Michigan Lawns
For most Michigan lawns, the ideal mowing height is:
3 to 3.5 inches
Cool-season grasses like Kentucky Bluegrass, Perennial Ryegrass, and Fine Fescue grow best when maintained at this height, while Turf Type Tall Fescue prefers to be a bit taller at 3.5 to 4.5 inches.
Taller grass blades allow the lawn to:
• Develop deeper roots
• Retain soil moisture
• Shade out weeds
• Resist heat stress
Keeping your lawn slightly taller is one of the easiest ways to improve turf health.
Why Cutting Your Lawn Too Short Causes Problems
Scalping the lawn (cutting grass too short) is one of the fastest ways to damage your turf.
When grass is cut too low, it can:
• Expose soil to sunlight, allowing weeds to germinate
• Reduce the lawn’s ability to retain moisture
• Stress the grass during hot weather
• Lead to thin or patchy turf
Many lawn problems actually begin with mowing height.
Adjust Your Mowing Height Throughout the Season
While 3–3.5 inches is a good target for most of the year, small adjustments can help your lawn perform even better.
Spring:
3 inches works well while the lawn is actively growing.
Summer:
Increase mowing height closer to 3.5–4 inches to protect against heat stress.
Fall:
Return to around 3 inches as temperatures cool and growth slows.
These small seasonal adjustments can make a big difference in turf quality.
Follow the One-Third Rule
We cannot stress enough, the importance of the one-third rule.
Never remove more than one-third of the grass blade during a single mowing.
If the lawn becomes too tall, it’s better to mow gradually over multiple cuts rather than removing too much at once.
This keeps the grass healthy and prevents shock to the plant.

Final Thoughts
Maintaining the correct mowing height is one of the most important factors in lawn health.
