Lawn Verdict
Montgomery 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 (41.5 inches) generally supports healthy lawns with minimal supplemental watering.
Seasonal Breakdown

With 30.6 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 29.3°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
With 41.5 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.
