Moss is the dominant pressure in wet PNW climates. Annual moss control treatments in early spring are standard. Avoid scalping — keep mow height at 2-3 inches to shade out moss and weeds.
Lawn Care Considerations in Seattle
PNW lawns battle moss year-round in shaded, wet conditions. Apply moss control treatments in early spring before the lawn fully greens up. Red thread fungus appears during prolonged cool wet stretches. Slugs and crane flies are common pest pressures. Tall fescue and perennial ryegrass dominate because they tolerate constant moisture and cooler temperatures.
