Reading the Ann Arbor SE lawn year
Ann Arbor SE 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 11 – Aug 26, and the year's main feeding all land before the Oct 10 frost closes the year.

Frequently asked questions
When should I overseed my lawn in Ann Arbor SE?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Ann Arbor SE that means roughly Aug 11 – Aug 26, timed 45–60 days before the average first fall frost (Oct 10) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Ann Arbor SE?
Aim for Apr 14 – May 5 — the estimated stretch when Ann Arbor SE soil approaches the ~55°F germination threshold, anchored to the average last frost (May 5). 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 Ann Arbor SE?
Keep mowing as long as the grass grows — in Ann Arbor SE that's typically until Oct 3 – Oct 24, around the average first fall frost (Oct 10). Take the final cut slightly shorter to discourage snow mold.
What grass grows best in Ann Arbor SE?
