About Lawn Care in Morton County, Kansas
Challenging conditions in Morton County
Morton County faces a tough lawn care environment with a difficulty score of 44.4, falling well below the national median of 50.0. Maintaining a green space in this USDA Zone 6b region is significantly harder than the Kansas state average of 59.1. Homeowners must work against high heat and limited natural moisture to keep turf healthy.
High heat and dry plains climate
The county receives just 17.7 inches of annual precipitation, far short of the 30-50 inches ideal for most lawn grasses. With 76 extreme heat days per year, nearly 20 more than the state average, lawns require intensive irrigation to survive the summer. The 4059 growing degree days indicate a long, warm season that accelerates grass growth when water is available.
Working with alkaline clay soils
Soil here is predominantly clay with a high sand content of 55.3% and a slightly alkaline pH of 7.25. While the pH is just above the ideal 6.0-7.0 range, the poorly drained nature of the soil makes proper aeration critical. Residents often need to manage water runoff carefully to prevent the clay-heavy texture from suffocating grass roots.
Managing near-constant dry spells
Drought is a persistent threat, with 99.7% of the county currently classified as abnormally dry. Over the past year, the area endured 15 weeks of drought, necessitating strict water conservation habits. Deep, infrequent watering and keeping grass taller can help lawns withstand these recurring dry periods.
Strategic planting for the high plains
Buffalograss or drought-tolerant fescue blends are the best choices for this Zone 6b climate. Aim to seed after the last spring frost on April 27 or plan for early fall before the first frost on October 23. Starting with the right seed and timing ensures your lawn survives the intense 79.2°F July heat.

- 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
