About Lawn Care in Rawlins County, Kansas

Overcoming Hardship in the High Plains

Rawlins County is a challenging environment for lawns, with a difficulty score of 43.2, well below the national median of 50.0. The Zone 6a climate in this region presents unique hurdles that require specialized grass types and dedicated maintenance. Growing a traditional green lawn here is a labor-intensive endeavor compared to the rest of the state.

Arid Climate and Short Growing Seasons

With only 21.8 inches of annual precipitation, Rawlins is significantly drier than the Kansas average of 30.3 inches. The growing season is shorter, reflected by 3,403 growing degree days and 58 extreme heat days per year. Supplemental irrigation is not optional here; it is the lifeline for any non-native turf grass.

Alkaline Silt Loam Challenges

The soil pH is a high 7.51, which is more alkaline than the ideal 6.0-7.0 range and may lock up essential nutrients like iron. The soil is classified as a well-drained silt loam with 21.7% clay and 16.9% sand. Homeowners may need to apply elemental sulfur to lower the pH and help the grass access the nutrients it needs to stay green.

Persistent Drought Preparedness

Rawlins County faced 30 weeks of drought over the past year, and 100% of the county is currently classified as abnormally dry. In this semi-arid environment, xeriscaping or choosing native buffalo grass is often more practical than thirsty traditional turf. Reducing mowing frequency and increasing blade height can help shade the soil and conserve every drop of water.

Planting with Care in Rawlins

Native Buffalo grass is the gold standard for this region because it thrives on low water and tolerates alkaline soil. Wait until after the May 4 frost to begin spring projects, as Rawlins has one of the later spring frost dates in Kansas. Be mindful that the growing window closes early, with the first fall frost typically arriving by October 12.

  • 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
