Lawn Care Considerations in Bothell

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.
