Data Story
About Lawn Care in Beaver County, Utah
Beaver County's challenging lawn landscape
With a lawn difficulty score of 25.9, Beaver County is a demanding environment for turf, coming in below the Utah state average of 28.5. This USDA Hardiness Zone 6a region faces significantly steeper challenges than the national median score of 50.0.
High heat and low rainfall
The county receives just 11.7 inches of annual precipitation, which is well below the 30-50 inches lawns ideally require. Combined with 50 extreme heat days per year and 2,638 growing degree days, homeowners must manage irrigation precisely to combat rapid evaporation.
Preparing your soil for success
While specific local soil data is currently limited, regional trends suggest a need for organic matter to improve moisture retention. We recommend a professional soil test to determine your specific pH and nutrient needs before the spring growing season begins.
Navigating a full year of drought
The county has spent all 53 weeks of the past year in drought conditions, with 100% of the area currently classified as abnormally dry. Residents should prioritize deep, infrequent watering early in the morning to maximize every drop during these persistent dry spells.
Strategic planting for high altitudes
Hardy cool-season grasses like Kentucky Bluegrass or Tall Fescue are best suited for Zone 6a. Aim to seed after the last frost on May 19th or in the early fall before the first frost arrives on September 29th.

- 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
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Keep lawn clear of debris
