About Lawn Care in Crook County, Oregon
Challenging High-Desert Lawn Care
Crook County’s score of 37.2 reflects a challenging environment where Hardiness Zone 6b winters meet very dry summers. Lawns here require significantly more intervention than those in the wetter western part of the state.
Sparse Rain and Intense Summer Heat
The county receives a meager 11.4 inches of annual precipitation, far below the 30-50 inches lawns prefer. With 35 extreme heat days, your grass faces significant evaporation stress, making smart irrigation the most critical part of your routine.
Testing for High Desert Alkalinity
Specific soil data for Crook County is currently unavailable, but high-desert soils often lean toward alkalinity. You should test your soil to see if sulfur is needed to lower the pH, ensuring your grass can access essential micronutrients.
Strategic Watering for Dry Soil
With 82.7% of the county currently abnormally dry, water conservation is a local necessity. Focus on early morning watering to minimize evaporation and use a weather-based irrigation controller to match your lawn's actual needs.
Wait for the Late Spring Frost
Choose drought-hardy species like Buffalo grass or specialized Tall Fescue blends for this region. Be patient with planting, as the last spring frost doesn't occur until June 2, giving you a shorter but intense window for establishment.

- 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
