Reading the Creston 2 SW lawn year
Creston 2 SW 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 12 – Aug 27, and the year's main feeding all land before the Oct 11 frost closes the year.

Frequently asked questions
When should I overseed my lawn in Creston 2 SW?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Creston 2 SW that means roughly Aug 12 – Aug 27, timed 45–60 days before the average first fall frost (Oct 11) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Creston 2 SW?
Aim for Apr 7 – Apr 28 — the estimated stretch when Creston 2 SW soil approaches the ~55°F germination threshold, anchored to the average last frost (Apr 28). 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 Creston 2 SW?
Keep mowing as long as the grass grows — in Creston 2 SW that's typically until Oct 4 – Oct 25, around the average first fall frost (Oct 11). Take the final cut slightly shorter to discourage snow mold.
