Data Story
About Lawn Care in Cottle County, Texas
The Hard Reality of High Plains Lawns
Cottle County presents a significant challenge with a lawn difficulty score of 24.4, well below the state average of 31.7. In Hardiness Zone 8a, the combination of low rainfall and extreme heat makes traditional green lawns a luxury.
Extreme Heat and Low Precipitation
Lawns struggle with only 23.9 inches of annual rain, which is far below the 30-inch ideal minimum for turf. This deficit is compounded by 111 days of extreme heat, forcing grasses into dormancy to survive the summer.
Sandy Loam and Alkaline Soil
The local soil is a very fine sandy loam, containing 51.9% sand for excellent drainage. However, the pH of 7.56 is quite alkaline, which can lock out essential nutrients like iron and phosphorus from the grass roots.
Battling Persistent Dry Conditions
Over the past year, the county endured 29 weeks of drought, and currently, nearly 40% of the area faces severe conditions. Residents should prioritize drought-tolerant native grasses and strictly follow local water restrictions.
Choosing Resilience Over Aesthetics
Buffalograss is a top recommendation for this climate because it survives on minimal water and handles the 111 heat days well. Wait until the last frost on March 30 before seeding to maximize the spring growing window.

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
- Raise mowing height to reduce heat stress
- 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
- Overseed with ryegrass for winter color
