Manageable Heat and Rain Patterns
The county receives 41.2 inches of annual precipitation, slightly below the state average of 44.2 inches. With only 14 extreme heat days and 3147 growing degree days, the climate generally supports steady growth without constant summer dormancy risks.

- 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

Lawn Care Advisory: Cass County
Lawn Verdict
Cass County sits in USDA hardiness zone 6a, a transitional zone where cool-season grasses dominate but some warm-season varieties can survive. with winter lows reaching around -10.0°F. and 3,146.85 growing degree days, sufficient for most common turfgrasses. Moderate rainfall (41.2 inches) generally supports healthy lawns with minimal supplemental watering.
Seasonal Breakdown
Wait until after April 25 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 73.1°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 23; this is the best renovation window. Cool winters (January averages 24.8°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
With 41.2 inches of annual rainfall, established lawns typically need watering only during extended dry spells. Currently, 100.0% of the county is in moderate drought according to the US Drought Monitor. Consider reducing irrigation frequency and allowing cool-season lawns to go semi-dormant during peak heat. Cool summers reduce water demand; overwatering is a bigger risk than drought stress.
