Natural grass grows well in the Northwest, until it doesn't. Shady yards turn to moss, high-traffic areas turn to mud every winter, and dogs wear paths that never recover. Synthetic turf solves those specific problems, but it isn't the right answer for every yard.
Turf makes the most sense in small or shady spaces, dog runs, play areas, and spots where grass keeps failing. A well-built turf install sits on a compacted aggregate base that drains quickly, so it's usable within minutes of a downpour. There's no mowing, no fertilizer, and no summer watering.
Natural grass still wins for big open lawns, for keeping things cool in summer, and for homeowners who enjoy lawn care. It also costs less to install per square foot. With good soil prep, proper drainage, and irrigation for the dry months, a real lawn can look great here.
Many yards end up with both: sod in the sunny open areas, turf in the shady side yard or the dog run. Either way, base preparation is what decides how it performs, so that's the part to ask about when you get a quote.
