Crabgrass pre-emergent Apr 13 – May 4 Soil nearing 55°F — must beat germination
Light spring feeding May 4 – Jun 1 After green-up, before summer stress
Aerate + overseed Aug 14 – Aug 29 Fall growth surge; established before cold
Main fall feeding Aug 18 – Sep 15 The year’s most important nitrogen
Winterizer feeding Sep 15 – Sep 29 Root reserves for spring green-up
Final mow Oct 6 – Oct 27 Growth stops around first frost

Reading the Trenton Falls lawn year

Trenton Falls 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 14 – Aug 29, and the year's main feeding all land before the Oct 13 frost closes the year.

Grasses that fit Trenton Falls

Frequently asked questions

When should I overseed my lawn in Trenton Falls?

For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Trenton Falls that means roughly Aug 14 – Aug 29, timed 45–60 days before the average first fall frost (Oct 13) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.

When do I put down crabgrass preventer in Trenton Falls?

Aim for Apr 13 – May 4 — the estimated stretch when Trenton Falls soil approaches the ~55°F germination threshold, anchored to the average last frost (May 4). 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 Trenton Falls?

Keep mowing as long as the grass grows — in Trenton Falls that's typically until Oct 6 – Oct 27, around the average first fall frost (Oct 13). Take the final cut slightly shorter to discourage snow mold.
