Data Story

About Lawn Care in Montezuma County, Colorado

Managing Turf in the High Desert

Montezuma County scores 30.3 for lawn difficulty, reflecting a more challenging environment than the state average of 37.4. In this Zone 6b climate, keeping a lush lawn requires significantly more effort than the national norm.

Dry Air and Consistent Heat

The county receives just 15.5 inches of precipitation annually, which is far below the 30-50 inches needed for ideal lawn health. With 23 days of extreme heat each year, supplemental watering is non-negotiable for traditional grass types.

Investing in Soil Health

While specific soil textures are not currently mapped, regional conditions often require amendments to balance alkalinity. Homeowners should aim to incorporate organic matter to bring the soil closer to the ideal 6.0-7.0 pH range.

Prolonged Dry Spells

The area has faced 53 weeks of drought over the past year, and 100% of the county remains abnormally dry. Using smart irrigation controllers can help manage water use effectively during these chronic dry periods.

Start Growing in Zone 6b

Drought-resistant Tall Fescue or Blue Grama are recommended for the local Zone 6b conditions. Target the window after the last spring frost on May 15 to begin your seeding or sodding projects.

Goal
  1. 1
    Prepare the seedbedMay 14 – May 27

    Mow low, dethatch or rake, and loosen the top ½ inch of soil so seed makes good contact.

    Sow seedMay 28 – Jun 25

    Best window to sow Buffalograss in Montezuma County, anchored to your local frost dates.

  3. 3
    EstablishJun 26 – Jul 23

    Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.

Watering while it germinates

Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.

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

Cool winters (January averages 28.3°F) mean slow or dormant growth; keep debris off the lawn.

Watering Guidance

Low annual precipitation (15.5 inches) makes irrigation essential for maintaining green turf through summer. Currently, 100.0% of the county is in abnormally dry according to the US Drought Monitor. Cool summers reduce water demand; overwatering is a bigger risk than drought stress.
