Lawn Care Advisory: Colfax County

Lawn Verdict

Colfax County sits in USDA hardiness zone 5b, a transitional zone where cool-season grasses dominate but some warm-season varieties can survive. with winter lows reaching around -15.0°F. and 3,218 growing degree days, sufficient for most common turfgrasses. Moderate rainfall (28.6 inches) generally supports healthy lawns with minimal supplemental watering.

Seasonal Breakdown

Wait until after April 27 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 75.2°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 11; this is the best renovation window. Cool winters (January averages 22.1°F) mean slow or dormant growth; keep debris off the lawn.

Watering Guidance

Moderate rainfall (28.6 inches) means lawns benefit from weekly deep watering during summer stress. 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. Standard warm-season watering of 1 inch per week is usually adequate during summer.
