TaskN Tonawanda windowWhy then
Crabgrass pre-emergent Apr 15 – May 6 Soil nearing 55°F — must beat germination
Light spring feeding May 6 – Jun 3 After green-up, before summer stress
Aerate + overseed Aug 16 – Aug 31 Fall growth surge; established before cold
Main fall feeding Aug 20 – Sep 17 The year’s most important nitrogen
Winterizer feeding Sep 17 – Oct 1 Root reserves for spring green-up
Final mow Oct 8 – Oct 29 Growth stops around first frost

Reading the N Tonawanda lawn year

N Tonawanda 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 16 – Aug 31, and the year's main feeding all land before the Oct 15 frost closes the year.

Frequently asked questions

When should I overseed my lawn in N Tonawanda?

For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in N Tonawanda that means roughly Aug 16 – Aug 31, timed 45–60 days before the average first fall frost (Oct 15) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.

When do I put down crabgrass preventer in N Tonawanda?

Aim for Apr 15 – May 6 — the estimated stretch when N Tonawanda soil approaches the ~55°F germination threshold, anchored to the average last frost (May 6). 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 N Tonawanda?

Keep mowing as long as the grass grows — in N Tonawanda that's typically until Oct 8 – Oct 29, around the average first fall frost (Oct 15). Take the final cut slightly shorter to discourage snow mold.
