Nevada Lawn Mowing Calendar
Published: February 1, 2026 · Updated: April 23, 2026
Nevada's desert climate and persistent water restrictions have fundamentally changed residential lawn care in Las Vegas and Reno over the past decade. What remains of traditional lawn is typically Bermuda Grass with winter Ryegrass overseeding in the south, or Kentucky Bluegrass in the cooler higher elevations of the Reno-Sparks area and rural Nevada.

Mowing Tips for Nevada
Never mow during peak afternoon heat (12–4pm) in summer. Morning mowing reduces heat stress on cut grass.
Raise mowing height by 15–25mm during heat waves. Taller grass shades roots and reduces soil moisture loss by up to 25%.
Never remove more than one-third of the blade in a single mow. Removing too much causes shock, browning, and weed invasion.
What Makes Mowing in Nevada Different
Mowing in Nevada is shaped more by water policy than by climate or grass biology. The Southern Nevada Water Authority's cash-for-grass program has removed over 200 million square feet of lawn in the Las Vegas valley since 1999, and much of what remains is limited to smaller functional areas like children's play zones. For the Bermuda/Rye combination that dominates remaining Las Vegas lawns, mowing follows the dual-season pattern common in the desert Southwest: Bermuda at 40-50mm weekly from April through October, transitioning to overseeded Rye at 50-65mm from December through April. The transition periods — late September and late April — are the most demanding. Nevada's low humidity and intense UV radiation desiccate cut grass surfaces quickly, making morning mowing and sharp blades particularly important. Las Vegas's alkaline caliche soils (pH 7.5-9.0) cause significant iron chlorosis, making chelated iron applications a standard practice for any lawn that remains. Reno and northern Nevada experience a very different lawn environment — higher elevation, more precipitation, and cooler summers support Kentucky Bluegrass and Fine Fescue lawns that function more like northern California or eastern Oregon. These northern Nevada communities still face summer water restrictions but with less aggressive conservation pressure than southern Nevada. Rural Nevada communities near mountain ranges often have well-water access that removes municipal restrictions, though the underlying groundwater resource concerns remain.

Frequently Asked Questions
When should I start mowing my lawn in Nevada?
Start mowing in Nevada when grass shows active green growth and soil temperature exceeds 10°C. For zone 9a, this is typically February–March. Set mower at maximum height for the first 2–3 cuts.
What height should I mow St. Augustine Grass in Nevada?
St. Augustine Grass in Nevada should be maintained at 75mm during spring and fall, raised to 90mm in summer. Never cut below 50mm.
How often should I mow my lawn in Nevada in summer?
In Nevada's zone 9a climate, St. Augustine Grass typically needs mowing every 7–14 days in peak summer. If growth slows in heat, extend the interval.
When should I stop mowing my Nevada lawn in fall?
Warm-season grasses in Nevada go dormant when temperatures drop below 10°C — typically they may not go fully dormant. Final mow at 75mm.
Should I raise my mowing height in Nevada summers?
Yes — raising mowing height by 15–25mm in summer is one of the most important adjustments for Nevada lawns. Taller grass shades roots, retains soil moisture, and reduces heat stress. This applies to all grass types.
