Conserving Water During Persistent Drought
Residents endured a full year of drought conditions, with 100% of the county still classified as abnormally dry. Mulching around lawn edges and watering before 10 a.m. are essential strategies to prevent moisture loss.
Optimal Timing for Santa Fe Lawns

- 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
