Data Story
About Lawn Care in Haskell County, Kansas
Haskell County's Uphill Lawn Battle
Haskell County scores a 45.1 for lawn difficulty, making it tougher to maintain grass here than the national median of 50.0. In this Zone 6b region, you face a more challenging environment than the Kansas state average of 59.1.
Dry Heat and High Demands
You manage just 18.3 inches of annual precipitation, far below the ideal 30-50 inches lawns prefer. With 72 extreme heat days and 4296 growing degree days, your grass requires heavy irrigation to survive the intense summer sun.
Sandy Loam Basics
Your soil is a well-drained fine sandy loam with a pH of 7.22, sitting just above the ideal 6.0-7.0 range. While the 48.0% sand content prevents pooling, it means you must fertilize carefully to prevent nutrients from washing away.
Managing the Dry Spells
The county endured 10 weeks in drought over the past year, though current conditions show no immediate dry areas. To stay ahead of the next cycle, keep mower blades at three inches or higher to shade the soil and preserve moisture.
Timing Your 6b Lawn
Drought-tolerant varieties like buffalograss or tall fescue are your best bets for this climate. Aim to seed between the last spring frost on April 23 and the first fall frost around October 21.

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
- 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
- Plan spring soil amendments based on fall test
- Keep lawn clear of debris
