Reading the Kaskaskia River Navigation Lock lawn year
Kaskaskia River Navigation Lock 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 31 – Sep 15, and the year's main feeding all land before the Oct 30 frost closes the year.

Frequently asked questions
When should I overseed my lawn in Kaskaskia River Navigation Lock?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Kaskaskia River Navigation Lock that means roughly Aug 31 – Sep 15, timed 45–60 days before the average first fall frost (Oct 30) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Kaskaskia River Navigation Lock?
Aim for Mar 18 – Apr 8 — the estimated stretch when Kaskaskia River Navigation Lock soil approaches the ~55°F germination threshold, anchored to the average last frost (Apr 8). 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 Kaskaskia River Navigation Lock?
Keep mowing as long as the grass grows — in Kaskaskia River Navigation Lock that's typically until Oct 23 – Nov 13, around the average first fall frost (Oct 30). Take the final cut slightly shorter to discourage snow mold.
