Reading the Port Alsworth 1 SW lawn year
Port Alsworth 1 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 Jul 14 – Jul 29, and the year's main feeding all land before the Sep 12 frost closes the year. With only ~102 frost-free days, the fall window is tight — miss it and the next real chance is spring.

Frequently asked questions
When should I overseed my lawn in Port Alsworth 1 SW?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Port Alsworth 1 SW that means roughly Jul 14 – Jul 29, timed 45–60 days before the average first fall frost (Sep 12) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When do I put down crabgrass preventer in Port Alsworth 1 SW?
Aim for May 12 – Jun 2 — the estimated stretch when Port Alsworth 1 SW soil approaches the ~55°F germination threshold, anchored to the average last frost (Jun 2). 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 Port Alsworth 1 SW?
Keep mowing as long as the grass grows — in Port Alsworth 1 SW that's typically until Sep 5 – Sep 26, around the average first fall frost (Sep 12). Take the final cut slightly shorter to discourage snow mold.
