This score far exceeds the Oregon state average of 38.9, thanks to a balanced 7b hardiness zone. Most turf varieties will flourish here with standard maintenance practices.
Ideal Rainfall and Moderate Heat
The county receives 33.2 inches of annual precipitation, placing it perfectly within the 30-50 inch ideal range for lawns. With only 17 extreme heat days—fewer than the state average of 23—your grass is less likely to suffer from summer scorch. The 1,931 growing degree days support a healthy, manageable growing pace.
Checking Your Local Soil Health
While specific county-wide soil metrics are unavailable, the region's lush landscape suggests generally productive soil. You should still test for pH to ensure it falls within the 6.0 to 7.0 range for optimal grass health. Proper drainage is key, especially given the healthy 33.2 inches of annual rainfall.
Smart Water Use Despite Good Rain
The county spent 27 weeks in drought over the last year, and 100.0% of the area is currently abnormally dry. Even with good annual rainfall, summer dry spells require efficient irrigation to keep lawns vibrant. Using rain barrels or smart timers can help you manage these seasonal shifts effectively.
