Is My Brown Lawn Dead or Just Dormant?
The Short Answer
It’s very likely dormant, not dead. Spokane’s most common lawn grass, Kentucky Bluegrass, naturally goes dormant and turns brown once temperatures consistently exceed 85°F. Spokane averages 26+ days a year above 90°F, so a browning lawn in summer is normal, not a sign of death.
Why Lawns Go Dormant
Dormancy is a survival mechanism. When heat and dryness threaten the plant, grass shuts down top growth and protects its root system, waiting for cooler, wetter conditions to resume growing.
Footprint Test
Walk across the lawn and look back — if footprints stay pressed down, the grass is dehydrated but usually still alive.
Color
Dormant grass is uniformly straw-brown; dead patches are often more localized or paired with bare soil.
Pull Test
Gently tug a small clump — dormant grass resists, dead grass comes up easily with no resistance.
What To Do
A light watering — about 15–20 minutes once a week — keeps dormant roots alive until cooler weather brings the green back on its own. You don’t need to (and shouldn’t try to) force a dormant lawn green in the middle of summer heat.
When to Worry
If patches stay brown well after temperatures cool in fall, or if you see thinning combined with visible pest activity, that may indicate a different issue — worth a quick inspection rather than assuming dormancy.
