Reading the Chicago Midway Airport 3SW lawn year
Chicago Midway Airport 3SW 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 2 – Sep 17, and the year's main feeding all land before the Nov 1 frost closes the year.

Frequently asked questions
When should I overseed my lawn in Chicago Midway Airport 3SW?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Chicago Midway Airport 3SW that means roughly Sep 2 – Sep 17, timed 45–60 days before the average first fall frost (Nov 1) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Chicago Midway Airport 3SW?
Aim for Mar 20 – Apr 10 — the estimated stretch when Chicago Midway Airport 3SW soil approaches the ~55°F germination threshold, anchored to the average last frost (Apr 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 Chicago Midway Airport 3SW?
Keep mowing as long as the grass grows — in Chicago Midway Airport 3SW that's typically until Oct 25 – Nov 15, around the average first fall frost (Nov 1). Take the final cut slightly shorter to discourage snow mold.
