Data Story

About Lawn Care in Worth County, Missouri

Exceptional Conditions for Easy Lawn Care

Worth County boasts an impressive lawn difficulty score of 81.1, making it one of the easiest places in the state to maintain turf. This score far exceeds both the national median of 50.0 and the Missouri average of 63.7. The county is located in USDA Hardiness Zone 5b, which is ideal for northern, cool-season grass varieties.

Cooler Summers Reduce Turf Stress

The region experiences only 20 extreme heat days annually, which is significantly lower than the Missouri state average of 37 days. While local precipitation data is limited, 3,269 growing degree days indicate a shorter, more manageable growing season. This cooler climate reduces the risk of heat-related browning and fungal diseases common in southern Missouri.

Optimal Soil Foundation for Healthy Grass

The soil foundation is a favorable silt loam with a pH of 6.14, placing it right within the ideal range for healthy grass. It is moderately well drained, which helps maintain moisture without drowning the root system. Homeowners here generally need fewer soil amendments and fertilizers compared to those in neighboring counties.

High Resilience and Minimal Drought Stress

Resilience is high in Worth County, which only experienced 3 weeks of drought over the last year. Although 100% of the county is currently flagged as abnormally dry, none of the area is suffering from severe drought. Occasional supplemental watering during dry weeks should be sufficient to keep lawns vibrant throughout the season.

Cool-Season Grasses Thrive in Zone 5b

Kentucky bluegrass and fine fescue are ideal for this cooler Zone 5b environment. Time your planting between the last spring frost on April 24 and the first fall frost on October 14 to maximize establishment. With such a high difficulty score, a little effort goes a long way toward achieving a lush, green lawn.

Seasonal Lawn Care Checklist

Spring

  • Apply pre-emergent herbicide when soil reaches 55F
  • Overseed bare spots once frost risk passes
  • 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

  • Core aerate compacted areas
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering

Winter

  • Avoid walking on frozen turf
  • Service mower and sharpen blades
  • Plan spring soil amendments based on fall test
  • Keep lawn clear of debris
