Reading the Seattle Sand Pt WSFO lawn year
Seattle Sand Pt WSFO runs on the classic northern rhythm: a short, important spring (pre-emergent before soil hits 55°F, one light feeding), a defensive summer (mow tall, water deep, feed nothing), and then the season that actually builds a lawn — early fall, when aeration, overseeding around Sep 24 – Oct 9, and the year's main feeding all land before the Nov 23 frost closes the year.

Frequently asked questions
When should I overseed my lawn in Seattle Sand Pt WSFO?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Seattle Sand Pt WSFO that means roughly Sep 24 – Oct 9, timed 45–60 days before the average first fall frost (Nov 23) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Seattle Sand Pt WSFO?
Aim for Feb 15 – Mar 8 — the estimated stretch when Seattle Sand Pt WSFO soil approaches the ~55°F germination threshold, anchored to the average last frost (Mar 8). It's an estimate: a soil thermometer reading 50–55°F at 2″ depth for several days is the precise trigger, and pre-emergent must go down before crabgrass sprouts, not after.
When should I stop mowing in Seattle Sand Pt WSFO?
Keep mowing as long as the grass grows — in Seattle Sand Pt WSFO that's typically until Nov 16 – Dec 7, around the average first fall frost (Nov 23). Take the final cut slightly shorter to discourage snow mold.
