Data Story
About Lawn Care in Emery County, Utah
Emery County's uphill lawn battle
With a difficulty score of 25.6, Emery County is one of the hardest places in Utah to maintain a traditional lawn. This Zone 6a county is significantly below the state average of 28.5 and the national benchmark of 50.0.
Hot, dry, and demanding
The county receives just 11.1 inches of annual precipitation while enduring 39 days of extreme heat. These conditions require intense irrigation management to keep grass from entering permanent dormancy during the 2,391 growing degree days.
Assessing your local soil
Data on local soil texture is currently unavailable, but high-desert soils in this region are often low in organic matter. We recommend adding compost to your lawn every spring to improve its ability to hold onto what little water is available.
Critical drought across the board
Currently, 100% of Emery County is in severe drought after a full year of dry conditions. Lawns are under extreme stress, and homeowners should prioritize high-traffic areas if they must limit water usage.
Planting for the Emery climate
Stick to the hardiest cool-season grasses that can withstand the May 18th to October 18th growing season. Seeding in late summer is often more successful here, as it avoids the most intense July heat while roots establish.

- Apply pre-emergent herbicide when soil reaches 55F
- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Mow at recommended height weekly
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Apply pre-emergent for winter weeds
