Data Story

About Lawn Care in Davis County, Utah

Davis County's superior lawn potential

Boasting a score of 37.4, Davis County is significantly easier for lawn care than the Utah average of 28.5. It also sits in a warmer Hardiness Zone 7b, providing a much longer and more flexible growing season.

Abundant rain and high energy

The county receives 23.2 inches of annual precipitation, which is nearly double the state average. This moisture, paired with 3,135 growing degree days, fuels aggressive lawn growth and helps mitigate the stress of 46 extreme heat days.

Strong growth in Davis soils

While detailed soil metrics are not currently available, the high precipitation suggests better nutrient cycling than in drier counties. Regular aeration is recommended to ensure the soil doesn't become compacted under the lush growth these conditions allow.

Managing water despite the rain

Even with better rainfall, the county has seen 53 weeks of drought and remains 100% abnormally dry. However, the lack of severe (D2+) drought areas makes it easier to maintain a healthy lawn with standard conservation practices.

The best growing window in Utah

Your growing season starts early on April 24th and stretches all the way to October 19th. This long window allows for a wide variety of grass types and gives fall-seeded lawns plenty of time to establish deep roots.

  3. 3

    Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.

Watering while it germinates

Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.

You’re in the transition zone — both cool- and warm-season grasses can work; the schedule above follows the species you selected.

Seasonal Lawn Care Checklist

Spring

  • 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

Aerate and overseed cool-season lawns by early fall, well before October 19; this is the best renovation window. Cool winters (January averages 29.1°F) mean slow or dormant growth; keep debris off the lawn.
