TaskNewport 1 SE windowWhy then
Crabgrass pre-emergent Jan 29 – Feb 19 Soil nearing 55°F — must beat germination
Light spring feeding Feb 19 – Mar 19 After green-up, before summer stress
Aerate + overseed Oct 17 – Nov 1 Fall growth surge; established before cold
Main fall feeding Oct 21 – Nov 18 The year’s most important nitrogen
Winterizer feeding Nov 18 – Dec 2 Root reserves for spring green-up
Final mow Dec 9 – Dec 30 Growth stops around first frost

Reading the Newport 1 SE lawn year

Newport 1 SE 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 Oct 17 – Nov 1, and the year's main feeding all land before the Dec 16 frost closes the year.

Frequently asked questions

When should I overseed my lawn in Newport 1 SE?

For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Newport 1 SE that means roughly Oct 17 – Nov 1, timed 45–60 days before the average first fall frost (Dec 16) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.

When do I put down crabgrass preventer in Newport 1 SE?

Aim for Jan 29 – Feb 19 — the estimated stretch when Newport 1 SE soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 19). 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 Newport 1 SE?

Keep mowing as long as the grass grows — in Newport 1 SE that's typically until Dec 9 – Dec 30, around the average first fall frost (Dec 16). Take the final cut slightly shorter to discourage snow mold.
