About Lawn Care in Montgomery County, Kansas
Warm-Season Success in Southeast Kansas
Montgomery County sits in Zone 7a, the warmest hardiness zone in this group, with a lawn difficulty score of 58.7. This score nearly matches the state average, indicating a typical but manageable experience for Kansas growers. The warmer winters and higher humidity create a distinct environment for southern-leaning turf varieties.
Highest Precipitation in the Region
With 44.0 inches of annual precipitation, Montgomery County is the wettest in this group and well within the ideal range for lawns. However, the 4,606 growing degree days—the highest among these counties—mean that grass grows rapidly and demands frequent attention. The frost-free season is long, stretching from early April to late October.
Acidic Soils Require Careful Monitoring
The soil pH here is 6.18, which is on the lower end of the ideal range but still very productive for most grasses. A clay content of 27.5% and sand at 18.8% provide a balanced texture that supports the county's high rainfall. Periodic soil testing is wise to ensure the pH doesn't drop too far into the acidic range.
Total Drought Coverage Despite High Rain
Surprisingly, 100% of the county is currently classified as abnormally dry, following 19 weeks of drought in the past year. This illustrates how quickly the high heat and 4,606 GDD can deplete even the 44.0 inches of annual rain. Mulching and maintaining a consistent watering schedule are essential during these dry transitions.
The Best Zone for Warm-Season Grass
Zone 7a is perfect for Bermuda, Zoysia, or even St. Augustine grass, which thrive in the heat and high precipitation. Start your planting projects after the last frost on April 6 to take full advantage of the long growing year. Your lawn will benefit from the extra moisture as long as you stay ahead of the rapid growth.

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
