About Lawn Care in Dawes County, Nebraska
High Difficulty in the Nebraska High Plains
Dawes County presents a significant challenge with a lawn difficulty score of only 30.8. This is far below the state average of 54.2, making it one of the most demanding areas in Nebraska to grow traditional turf.
Extreme Heat and Limited Rainfall
The county receives just 15.2 inches of annual precipitation, roughly half of what most lawns require. Combined with a staggering 53 days of extreme heat over 90°F, natural grass faces intense stress nearly every summer.
Managing Alkaline and Sandy Loam
The soil pH of 7.35 is more alkaline than the ideal 6.0-7.0 range, which can lock up essential micronutrients like iron. With 46.3% sand, the well-drained loam soil loses moisture quickly, necessitating frequent but targeted irrigation.
Bracing for Persistent Severe Drought
Dawes County has been in drought for all 53 weeks of the past year, with nearly 40% of the area in severe drought. In these conditions, many residents find success using native prairie grasses that require significantly less water.
Patience is Key for May Planting
In hardiness zone 5a, Buffalograss is the best choice for resisting heat and drought. Your growing window starts late, with the last spring frost occurring on May 14th and the first fall frost arriving by September 30th.

- 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
