Crabgrass pre-emergent May 4 – May 25 Soil nearing 55°F — must beat germination
Light spring feeding May 25 – Jun 22 After green-up, before summer stress
Aerate + overseed Jul 5 – Jul 20 Fall growth surge; established before cold
Main fall feeding Jul 9 – Aug 6 The year’s most important nitrogen
Winterizer feeding Aug 6 – Aug 20 Root reserves for spring green-up
Final mow Aug 27 – Sep 17 Growth stops around first frost

Reading the Kaltag Airport lawn year

Kaltag Airport 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 Jul 5 – Jul 20, and the year's main feeding all land before the Sep 3 frost closes the year. With only ~101 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 Kaltag Airport?

For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Kaltag Airport that means roughly Jul 5 – Jul 20, timed 45–60 days before the average first fall frost (Sep 3) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.

When do I put down crabgrass preventer in Kaltag Airport?

Aim for May 4 – May 25 — the estimated stretch when Kaltag Airport soil approaches the ~55°F germination threshold, anchored to the average last frost (May 25). 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 Kaltag Airport?

Keep mowing as long as the grass grows — in Kaltag Airport that's typically until Aug 27 – Sep 17, around the average first fall frost (Sep 3). Take the final cut slightly shorter to discourage snow mold.
