A Douglas-fir can look green and upright right up until the day it tips over, and laminated root rot is one of the most common reasons why in western Oregon.
This native fungal disease spreads from tree to tree where roots touch, slowly decaying the roots that anchor a fir in place. Crowns may thin, yellow, or produce heavy stress cone crops, but many infected trees show few obvious symptoms above ground.
As fall rains saturate the soil and the first windstorms move through the southern Willamette Valley, trees with compromised roots are far more likely to uproot entirely. Infection centers often appear as small openings in a stand where trees have fallen or died over the years.
Lane Tree Doctor looks at the whole group of trees, not just the one that worries you, and explains what the evidence shows. For properties in Pleasant Hill, Dexter, and the foothills, knowing where root disease is present makes planning safer.
