Data Story
About Lawn Care in Kimball County, Nebraska
The State's Toughest Turf Test
Kimball County is one of the most difficult places in Nebraska to maintain a lawn, with a score of 32.0. This is far below both the state average (54.2) and the national median (50.0). In Hardiness Zone 5a, the combination of extreme dryness and a short growing season creates a high-stakes environment.
Arid Conditions and Late Frosts
With only 16.3 inches of annual rainfall, the county receives barely half of the ideal 30-50 inch range for turf. The growing season is compressed, beginning late after a May 25 spring frost and ending early on September 26. Just 2,044 growing degree days are available, meaning grass grows much more slowly here than elsewhere in the state.
Fast-Draining, Alkaline Soils
The soil contains 53% sand, causing what little moisture falls to drain away rapidly. A pH of 7.15 is slightly above the ideal range, which can occasionally lock out specific micronutrients like iron. Regular applications of organic compost can help lower pH slightly and improve the soil's ability to hold onto water.
Severe Drought Is the New Normal
A staggering 100% of Kimball County is currently in severe drought, having spent the entire last year (53 weeks) under drought conditions. Traditional lawns are extremely difficult to sustain under these circumstances without heavy, expensive irrigation. Residents should consider xeriscaping or choosing the most drought-hardy native grasses available.
Strategic Planting for Survival
Buffalograss and Blue Grama are the only practical choices for this extremely arid Zone 5a environment. You have a very narrow window to seed between the late May frost and the early September freeze. High-effort maintenance is required here, but selecting the right species makes success possible.

Pick a grass and a goal to get a personalized schedule anchored to this county’s frost dates.
- 1Prepare the seedbedMay 24 – Jun 6
Mow low, dethatch or rake, and loosen the top ½ inch of soil so seed makes good contact.
- 2Sow seedJun 7 – Jul 5
Best window to sow Buffalograss in Kimball County, anchored to your local frost dates.
- 3EstablishJul 6 – Aug 2
Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.
Sandy soil drains fast — water lightly and often. Aim to keep the top 1 inch moist with 2–3 short cycles a day (~0.1 in each) until germination, then taper to deeper, less frequent watering.
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

Cool summers (July averages 69.3°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before September 26; this is the best renovation window. Cool winters (January averages 25.8°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
Low annual precipitation (16.3 inches) makes irrigation essential for maintaining green turf through summer. Currently, 100.0% of the county is in severe drought according to the US Drought Monitor. Mandatory watering restrictions may be in effect; follow local guidelines and prioritize tree and shrub watering over turf. Cool summers reduce water demand; overwatering is a bigger risk than drought stress.
