Reading the Pretty Rock lawn year
Pretty Rock 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 25 – Aug 9, and the year's main feeding all land before the Sep 23 frost closes the year. With only ~126 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 Pretty Rock?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Pretty Rock that means roughly Jul 25 – Aug 9, timed 45–60 days before the average first fall frost (Sep 23) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Pretty Rock?
Aim for Apr 29 – May 20 — the estimated stretch when Pretty Rock soil approaches the ~55°F germination threshold, anchored to the average last frost (May 20). 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 Pretty Rock?
Keep mowing as long as the grass grows — in Pretty Rock that's typically until Sep 16 – Oct 7, around the average first fall frost (Sep 23). Take the final cut slightly shorter to discourage snow mold.
