About Lawn Care in Curry County, Oregon
Subtropical Influence in Curry County
Curry County’s lawn difficulty score of 33.8 is lower than the state average due to extreme rainfall and very acidic soils. However, its Hardiness Zone 9b is one of the warmest in Oregon, offering a unique opportunity for specialized turf.
The Wettest Corner of the State
An incredible 81.8 inches of rain falls here annually, creating a constant challenge for soil aeration and disease control. Despite the rain, only 9 extreme heat days occur, keeping your lawn cool and hydrated through most of the year.
Extreme Soil Acidity Management
At 4.38, the soil pH in Curry County is among the most acidic in the nation, requiring heavy and frequent lime applications to reach the ideal 6.0 range. The 32.3% sand content helps with drainage, which is vital given the heavy annual rainfall.
Stable Moisture with Low Drought
Currently, only 26.1% of the county is abnormally dry, and there were only 25 weeks in drought last year. Your biggest water challenge isn't a lack of it, but managing the runoff and nutrient leaching that comes with heavy Pacific storms.
Winter-Ready for Early Growth
Because the last spring frost hits early on February 17, you can start your lawn prep before almost anyone else in Oregon. Fine Fescue and Seashore Paspalum are excellent choices for these wet, acidic coastal conditions.

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
- Raise mowing height to reduce heat stress
- 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
- Overseed with ryegrass for winter color

Common Lawn Problems in Curry County
Excess Moisture & Fungal Disease
High annual rainfall (82 inches) increases risk of fungal diseases like brown patch and dollar spot. Ensure good drainage and avoid overwatering.
Acidic Soil
Soil pH of 4.4 is below the ideal range for most grasses (6.0-7.0). Apply agricultural lime to raise pH gradually.
Persistent Drought Conditions
Curry County experienced drought conditions for 25 of the past 52 weeks. Prioritize water-efficient grasses and consider reducing lawn area.
