Reading the Mullen 21 NW lawn year
Mullen 21 NW 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 Aug 2 – Aug 17, and the year's main feeding all land before the Oct 1 frost closes the year. With only ~144 frost-free days, the fall window is tight — miss it and the next real chance is spring.

Frequently asked questions
When should I overseed my lawn in Mullen 21 NW?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Mullen 21 NW that means roughly Aug 2 – Aug 17, timed 45–60 days before the average first fall frost (Oct 1) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Mullen 21 NW?
Aim for Apr 19 – May 10 — the estimated stretch when Mullen 21 NW soil approaches the ~55°F germination threshold, anchored to the average last frost (May 10). 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 Mullen 21 NW?
Keep mowing as long as the grass grows — in Mullen 21 NW that's typically until Sep 24 – Oct 15, around the average first fall frost (Oct 1). Take the final cut slightly shorter to discourage snow mold.
