How to use this calendar
Start with seed type, then trust the soil
State timing is useful because frost, rainfall, soil texture, and heat stress change the risk profile. It is still a filter, not a guarantee. Confirm the grass species, soil temperature, and watering plan before you spread seed.
Local constraints
- Extreme aridity — driest state in the US
- Las Vegas heat exceeds 115F in summer
- Ornamental grass bans in new Las Vegas developments
- Highly alkaline soil with caliche hardpan
- Extremely hard water damages soil structure
- Intense UV degrades turf quality
Warm grass
Bermuda and zoysia wait for spring heat
Warm-season seed needs warmer soil. The same state can have two correct windows depending on grass type.
Seasonal plan
Season-by-season planting plan for Nevada
Use the Nevada calendar as a timing sequence: prep before the window, seed when soil temperature is right, and protect new turf through the first stress season.

Transition zone
Grass type decides
50 to 70F soil
March - May
Spring
- 1Turn on and test irrigation systems in late March (Las Vegas) or mid-April (Reno, Carson City, Elko) — check for broken heads, cracked lines from freeze damage, and proper coverage patterns before relying on the system
- 2Apply pre-emergent herbicide when soil temps reach 55 degrees — early March in Las Vegas, mid-to-late April in northern Nevada; track soil temps through UNR Extension resources rather than guessing by calendar date
- 3Scalp bermuda lawns in Las Vegas in mid-March when green-up begins — cut to 0.5 to 0.75 inches and bag all clippings to expose soil to warming sunlight and accelerate spring transition
- 4Begin mowing cool-season lawns in Reno and Carson City at 3 inches when growth resumes in mid-April — do not scalp cool-season grasses, which need leaf blade area to photosynthesize and build spring root reserves
- 5Seed bermuda in Las Vegas in late April through May when soil temps hold above 65 degrees — seed cool-season lawns in northern Nevada in May if fall seeding was missed, though fall remains the preferred window
- 6Submit a soil test through UNR Extension — Nevada's alkaline soils and hard water create soil chemistry that changes year to year, and testing annually is the only way to stay ahead of pH creep and nutrient lockout
June - August
Summer
- 1Water before 5 AM in Las Vegas and before 6 AM in northern Nevada — this is the single most impactful water conservation practice in a state where evaporation and wind are your biggest irrigation enemies
- 2Deliver 1 to 1.5 inches of water per week — in Las Vegas, split into 3 to 4 sessions on sandy soil; in Reno, 2 deep sessions per week on clay-loam soil; adjust based on wind conditions that reduce sprinkler efficiency
- 3Raise mowing height to maximum for your grass type during peak heat — 2 inches for bermuda in Las Vegas, 3.5 to 4 inches for fescue in northern Nevada to shade soil and reduce evaporation
- 4Do not fertilize cool-season lawns in Reno from mid-June through August — summer nitrogen stresses heat-affected grass, promotes shallow root growth, and increases disease susceptibility during the most challenging months
- 5Apply a light fertilizer (0.5 lb nitrogen per 1,000 sq ft) to bermuda in Las Vegas in June — bermuda is in its prime growing season and responds well to summer feeding when it can actually use the nutrients
- 6Monitor for white grubs in northern Nevada lawns in late July — irregular brown patches that peel up like loose carpet indicate grub feeding on roots below the surface
September - November
Fall
- 1Overseed cool-season lawns in Reno, Carson City, and Elko from September 1 through October 1 — this is the optimal establishment window for northern Nevada when soil is warm and air is cooling
- 2Core aerate cool-season lawns in northern Nevada in September — the volcanic ash, decomposed granite, and compacted construction soils benefit enormously from annual aeration before winter dormancy
- 3Apply fall fertilizer (1 lb nitrogen per 1,000 sq ft) to cool-season lawns in mid-September in northern Nevada to support root development and recovery from summer stress
- 4Apply winterizer fertilizer (high potassium, like 8-2-12) in late October in northern Nevada and early November in Las Vegas to harden grass for winter freeze cycles
- 5Gradually reduce irrigation through October as temperatures cool — most Reno-area lawns need their last watering by late October before system winterization
- 6Overseed bermuda with annual ryegrass in Las Vegas in mid-October if winter color is desired — this is optional and will increase water use during the mild winter months
December - February
Winter
- 1Winterize irrigation systems in northern Nevada by early November — blow out all lines with compressed air to prevent freeze damage in pipes and heads that will cost hundreds to repair in spring
- 2Las Vegas bermuda is dormant from November through February — no fertilizer, no mowing; water only if you've gone 4-plus weeks without any precipitation, which happens regularly in the desert
- 3Spot-treat winter weeds in northern Nevada lawns on mild days above 40 degrees — henbit, chickweed, and annual bluegrass germinate during fall and grow slowly through winter when your lawn can't compete
- 4Soil test in January or February through UNR Extension — Nevada's alkaline soils and hard water create changing soil chemistry that should be monitored annually to track pH drift and nutrient availability
- 5Research turf removal rebates if you're considering reducing lawn area — SNWA in Las Vegas pays $3 per square foot and TMWA in Reno offers similar conservation programs with real financial incentives
- 6Order grass seed by February for spring planting — improved bermuda and RTF fescue varieties sell out quickly at northern Nevada garden centers as spring approaches
Regional timing notes
Nevada is not one planting zone
Use these regional notes to adjust the statewide window for elevation, soil, heat, irrigation pressure, and local grass type.
Las Vegas Valley / Southern Nevada
The Las Vegas Valley — Las Vegas, Henderson, North Las Vegas, Summerlin, and surrounding unincorporated Clark County — is home to 2.3 million people in a Mojave Desert basin that receives 4 to 5 inches of annual rainfall. Zone 9a to 9b conditions bring summer highs exceeding 115 degrees for weeks at a time, winter lows in the mid-20s (cold enough to send bermuda fully dormant for three months), and year-round aridity that makes every irrigation dollar count. The soil is desert sand and caliche — alkaline (pH 8.0 to 9.0), nearly devoid of organic matter, and underlain by impenetrable calcium carbonate hardpan in many areas that must be mechanically broken before any lawn installation. Clark County banned new front-yard ornamental grass in 2003, and the SNWA pays $3 per square foot to remove existing turf through their Water Smart Landscapes program. Bermuda is the only viable lawn grass, and it's increasingly confined to functional backyards rather than ornamental front-yard displays. The conversation about a broader bermuda ban surfaces periodically in local politics, reflecting the ongoing tension between residential water use and Lake Mead's declining levels.
- Water before 5 AM without exception — daytime irrigation in Las Vegas summer heat loses 60 percent or more to evaporation before reaching the root zone, making afternoon watering an expensive way to irrigate the atmosphere
- Bermuda needs 1 to 1.5 inches of water per week in summer, delivered in 3 to 4 sessions — the sandy soil and extreme heat demand more frequent but shorter watering cycles than clay soils in other states
Reno-Sparks / Northern Nevada
The Reno-Sparks metro area sits at 4,500 feet in the Truckee Meadows, flanked by the Sierra Nevada to the west and the Virginia Range to the east. Zone 6b to 7a conditions bring genuine four-season weather: hot dry summers (95 to 100 degrees), cold winters (teens to single digits), and 7 to 8 inches of annual precipitation — most falling as winter snow that melts and runs off rather than soaking into lawns. The soil is volcanic ash, decomposed granite, and clay-loam, generally well-drained but alkaline (pH 7.5 to 8.0) and low in organic matter. Wind is a defining factor — the Washoe zephyr, a powerful downslope wind from the Sierra, can gust to 80 mph and devastate sprinkler efficiency, blow newly seeded areas bare, and desiccate exposed turf. The Truckee River provides the region's water supply, and drought years create real conservation pressure. Cool-season grasses — Kentucky bluegrass and tall fescue — dominate the residential landscape. RTF water saver fescue is gaining market share rapidly as TMWA promotes water-efficient alternatives and homeowners feel the pinch of rising water costs tied to Truckee River allocation limits.
- RTF water saver fescue reduces irrigation needs by 30 percent compared to Kentucky bluegrass — in a water-constrained market like Reno, this difference shows up meaningfully on your TMWA bill from May through September
- The volcanic ash soil drains fast but holds almost no nutrients — fertilize in smaller, more frequent applications (three light passes rather than two heavy ones) to prevent nutrients from leaching through before roots absorb them
Rural Nevada / Elko-Carson City
Rural Nevada encompasses a vast geographic range — from Carson City and the Carson Valley (Gardnerville, Minden) in the west to Elko, Winnemucca, and Ely in the north and east. Carson City sits at 4,700 to 5,000 feet in Zone 6b with cold winters and warm but manageable summers, with slightly better soil than Reno thanks to Carson River valley alluvium and former ranch land. The Carson Valley around Minden and Gardnerville offers some of the best lawn-growing conditions in the state — fertile loamy soil, reliable well water, and cooler summers than the Truckee Meadows. Elko at 5,100 feet in Zone 5b to 6a experiences genuinely harsh winters (minus 20 is not unusual) and hot dry summers, with ranching culture that favors practical landscapes over manicured turf. Water sources in rural Nevada vary from mountain wells to river diversions to municipal systems, and many rural properties rely on well water that can be extremely hard. The growing season in these communities runs from mid-April through mid-October in the Carson Valley, and mid-May through September in Elko. Cool-season grasses are the only option, with Kentucky bluegrass and tall fescue blends dominating in the western communities and hardier KBG and buffalo grass making sense in the colder eastern reaches.
- Carson Valley's slightly higher precipitation and cooler summers make it the best lawn-growing environment in Nevada — the fertile valley bottom soils around Minden and Gardnerville respond well to a standard cool-season lawn program that would fail in Reno or Las Vegas
- Elko's Zone 5b winters demand cold-hardy grass selection — standard tall fescue can suffer winterkill at minus 20, so Kentucky bluegrass or KBG-dominant blends are safer choices for the northeastern Nevada ranching communities
