What Type of Grass Grows Best in Seattle?

Seattle’s cool, rainy climate is perfect for cool-season grasses that love moisture, handle shade, and stay green most of the year. Some of the best options for local lawns include:

• Perennial Ryegrass— Quick to germinate, durable under foot traffic, and reliable for family-friendly yards.

• Fine Fescue— Shade-tolerant with a soft texture, perfect for homes surrounded by trees.

• Kentucky Bluegrass— Lush and vibrant, especially when paired with rye or fescue for a balanced, hardy mix.

Warm-season grasses like Bermuda or Zoysia don’t hold up here—they struggle in Seattle winters and go dormant too early.

Why Seattle Lawns Struggle

Our climate can be beautiful, but it’s also tough on lawns. Common challenges include:

• Too much moisture→ moss, fungus, and root rot

• Too much shade→ patchy growth and thinning areas

• Clay-heavy soils→ poor drainage and compacted roots

Without proper care, even the healthiest grass can quickly turn into a soggy, moss-filled lawn.

How to Keep Your Seattle Lawn Healthy

With the right care plan, your lawn can stay green and resilient year-round. Here’s what we recommend:

• Aerate yearly to loosen compacted soil and improve root growth.

• Mow high (2.5–3 inches) to encourage deeper, stronger roots.

• Fertilize lightly in spring and fall with a slow-release formula suited for PNW soils.

• Treat moss carefully—but also address the cause (shade and drainage).

• Water smart—avoid overwatering during Seattle’s rainy months.
