Rated 4.8 Across 400+ Reviews


In the diverse climate of Utah, where temperatures can fluctuate significantly throughout the year, it is important to keep your lawn at a healthy length through the seasons. Cool-season grasses (Kentucky bluegrass, fine fescue, etc.) emerge as the ideal choice for achieving a lush and resilient lawn in our area, but what is the ideal height for these types of turfs? The team at Holmes Lawn & Pest put together this guide to help you answer this question and maintain the perfect lawn height in every season. 

The Standard Mowing Height For Utah

Maintaining a standard mowing height between 2 to 4 inches is the key to cultivating a healthy and resilient lawn in Utah. This range strikes a delicate balance, providing the optimal conditions for grass growth while addressing the diverse challenges posed by the state's varied climate. Keeping the grass within this height range encourages deep root development, enhances drought resistance, and promotes a thick, lush turf. The slightly taller grass blades offer shade to the soil, aiding in moisture retention during the warmer months and providing insulation against the cold in winter.

Spring Mowing Height

As spring unfolds in Utah, the emergence of new growth and the transition from winter dormancy mark a critical period for lawn care enthusiasts. Adjusting your lawn mower to a slightly lower setting, typically between 2 to 3 inches, during this season is a strategic move with multiple benefits. Lowering the mowing height in spring helps remove any accumulated thatch and winter debris, providing a clean slate for the fresh, tender grass blades to reach sunlight and nutrients. This initial trim serves as a rejuvenating boost, promoting the growth of a more vigorous and vibrant lawn.

Maintaining a slightly lower mowing height in spring enhances the lawn's resistance to common springtime challenges, such as fungal diseases. With increased air circulation at a shorter grass height, the risk of moisture retention and the development of fungal issues like snow mold is significantly reduced. This practice also encourages a more upright growth habit, preventing the grass from becoming excessively lush and prone to disease. 

Summer Mowing Height

The summer sun in Utah makes maintaining an optimal lawn mowing height paramount for the health and vitality of your grass. Setting your lawn mower to the standard 2 to 4 inches during the summer months promotes both aesthetic appeal and the resilience of the turf. The slightly taller mowing height in summer offers several advantages, primarily centered around the well-being of the grass blades and the overall health of the lawn.

The increased mowing height provides shade to the soil, aiding in moisture retention and reducing the risk of water evaporation. This is particularly crucial in Utah's arid climate, where water conservation is a key consideration. The shade cast by the taller grass blades also helps suppress weed growth, maintaining a neat and uniform appearance. Furthermore, a grass height of 2 to 4 inches allows for more extensive root development, enhancing the lawn's ability to withstand periods of heat stress and making it more resistant to drought conditions.

A slightly higher mowing height in summer ensures that the grass retains more energy, contributing to a thicker and more resilient turf. Taller grass and deeper roots allow for more nutrients to be absorbed, which is crucial to proper growth and sustained health during the damaging effects of the summer heat. 

Fall Mowing Height

Fall lawn care practices in Utah must adapt to the changing needs of the grass. Adjusting the mowing height during fall to approximately 1 inch lower than your summer setting is a strategic maneuver that takes into account the slowing growth of the grass and the impending winter dormancy. The slight reduction in mowing height ensures that your lawn does not become overstressed by trying to absorb enough nutrients to sustain more robust plant matter, which is especially difficult in colder temperatures. 

During fall, grass growth naturally begins to taper off as temperatures cool, and daylight hours decrease. By lowering the mowing height by about an inch, homeowners can also help prevent the grass from becoming excessively lush and prone to matting under layers of fallen leaves. The reduction in mowing height during the fall season helps prevent the development of fungal diseases, such as snow mold, which can thrive in excessively tall and matted grass. The shorter grass allows for improved air circulation, reducing the risk of moisture retention and creating a less hospitable environment for disease. 

Winter Mowing Height

Maintaining a winter lawn in Utah between the range of 2 to 4 inches is a strategic approach that helps fortify the grass before it enters dormancy. The taller grass acts as a natural insulator, providing protection against the extreme cold and potential frost. This insulation helps prevent the grass crowns from being exposed to harsh winter conditions, reducing the risk of winter damage. The range of 2 to 4 inches ensures that the grass retains enough leaf surface for photosynthesis even during the dormant period, enabling it to store essential nutrients and energy for a robust resurgence come spring. 

Lawn Mowing Tips For Utah

Achieving and maintaining a healthy lawn in Utah requires a nuanced approach to mowing heights throughout the seasons. By adapting your mowing practices to the specific needs of your lawn during each season, you'll foster a resilient and visually pleasing turf that can withstand the challenges of Utah's climate. Take the time to observe your lawn, adjust your mower height accordingly, and enjoy the rewards of a lush and vibrant outdoor space year-round. Call Holmes today for more information on proper lawn mowing in Utah, and keep the following tips in mind: 

  • Mowing Height: Keep your lawn mower set to a height between 2 to 4 inches.
  • 1/3 Rule: Never remove more than 1/3 of the grass blade length in a single mowing session.
  • Regular Mowing: Mow your lawn weekly or bi-weekly in order to maintain healthy growth through the seasons.
  • Sharp Blades: Regularly sharpen mower blades to ensure a clean cut, promoting healthier grass.
  • Dry Mowing: Mow when the grass is dry to prevent clumping and achieve a more even cut.
  • Alternate Patterns: Change mowing patterns regularly to prevent soil compaction and encourage upright grass growth.
  • Leave Clippings: Allow grass clippings to remain on the lawn as they decompose, providing natural fertilization.
  • Adjust For Seasons: Adapt mowing height according to seasonal needs, such as slightly lower in fall and higher in spring.
