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

Lawn Care Advisory: Spencer County

Lawn Verdict

Spencer County sits in USDA hardiness zone 6b, a transitional zone where cool-season grasses dominate but some warm-season varieties can survive. with winter lows reaching around -5.0°F. Moderate rainfall (49.8 inches) generally supports healthy lawns with minimal supplemental watering.

Seasonal Breakdown

Target mid-to-late spring for seeding once soil temperatures stabilize above 50°F. Cool summers (July averages 74.9°F) reduce heat stress — maintain regular mowing and moderate watering. With 34.2 days above 90°F annually, warm-season grasses recover faster from summer stress than cool-season types. Fall is the prime seeding season here; aerate, overseed, and fertilize cool-season grasses before October. Cool winters (January averages 31.0°F) mean slow or dormant growth; keep debris off the lawn.

Watering Guidance

With 49.8 inches of annual rainfall, established lawns typically need watering only during extended dry spells. The county is currently free of drought conditions. Cool summers reduce water demand; overwatering is a bigger risk than drought stress.
