Seasonal Lawn Care Checklist

Spring

  • Apply pre-emergent herbicide when soil reaches 55F
  • Overseed bare spots once frost risk passes
  • 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

  • Core aerate compacted areas
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering

Winter

  • Avoid walking on frozen turf
  • Service mower and sharpen blades
  • Plan spring soil amendments based on fall test
  • Keep lawn clear of debris

Lawn Verdict

Oxford County sits in USDA hardiness zone 5a, a transitional zone where cool-season grasses dominate but some warm-season varieties can survive. with winter lows reaching around -20.0°F. though only 1,848.94 growing degree days favor cool-season varieties like Kentucky bluegrass and fescue. Moderate rainfall (47.3 inches) generally supports healthy lawns with minimal supplemental watering.

Seasonal Breakdown

Wait until after May 17 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 67.1°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 1; this is the best renovation window. Winters are harsh (January averages 16.1°F); avoid foot traffic on frozen turf and plan snow mold prevention.

Watering Guidance

With 47.3 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.
