Data Story
About Lawn Care in Kosciusko County, Indiana
Sandy Soils Lower Maintenance Scores
Kosciusko County’s lawn difficulty score of 67.8 is slightly below the state average, reflecting more challenging growing conditions. Homeowners in this 6a hardiness zone must contend with soil that loses moisture rapidly compared to central Indiana.
Cool Summers Benefit Cool-Season Grass
While the county only sees 10 extreme heat days per year, its 39.9 inches of annual precipitation is lower than the state average of 44.2. Low heat stress is a major advantage, but the shorter 3,025 growing degree days means slower recovery from foot traffic.
Fine Sandy Loam Requires Frequent Water
With a high sand content of 51.8%, these well-drained soils do not hold water or nutrients well. The slightly acidic pH of 5.90 suggests a light application of lime could help move the soil toward the ideal 6.0 to 7.0 range.
Extended Drought Vulnerability
The county spent 34 weeks in drought over the past year, and 96.2% of the area is currently abnormally dry. Because the sandy soil drains so quickly, lawns here require more consistent irrigation during these dry spells than those in clay-heavy counties.
Maximize the Northern Growing Season
The window between the last frost on April 28 and the first frost on October 24 is your time to shine. Perennial Ryegrass and Fine Fescues perform well in this cooler climate and sandy texture.

Seasonal Lawn Care Checklist

- 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
