Know before you mow
We watch real weather for your ZIP code and tell you the exact moment it's worth mowing, feeding, treating, or watering — so nothing's wasted and nothing's missed. A handful of emails a year. No app to check.
Cool-season lawn regions only for now — 11 states currently covered.
✂️ Mow time
Growth has accumulated enough since the last mow (as of 14 March 2026).
Same model
as our validated UK product — real soil-temperature and water-balance physics, not a calendar rule
11 cities
backtested against 86 years of US weather before this launched
How it works
Three steps to set up. Then we do the watching.
Drop in your ZIP
Takes about 30 seconds. No app to install, no account to create, no card.
We watch the real weather
Soil temperature, rainfall, and evapotranspiration for your exact spot, checked every single day.
You get an email when it matters
Only when there's something worth acting on. No daily digests, no noise.
What you'll actually get
No daily updates, no noise — just an email exactly when one of these four things is true.
Spring feed
The exact week your lawn can actually use nitrogen. Too early and it washes straight through; too late and you've missed the growth spurt.
Moss & weed treatment
Timed to land before germination actually starts, so the treatment has something to work against instead of going down early for nothing.
Mow rhythm
Mow exactly as often as your lawn's real growth calls for — never scalped after a growth spurt, never shaggy in a lull.
Drought watch
The moment your lawn is genuinely water-stressed, not just looking a bit dry — so you know whether watering is worth it or it's fine to let go dormant.
Where Turf Alert works today
The US splits between cool-season grass (North) and warm-season grass (South) — completely different growth biology. We've only validated the model for cool-season regions so far, so signup is limited to ZIP codes in:
Washington · Oregon · Utah · Colorado · Minnesota · Illinois · Michigan · Missouri · New York · Massachusetts · Washington DC
Outside these states? We're not there yet — nothing to sign up for until the model's been checked against your region's climate.
Questions people actually ask
Is it really free?+
Yes. Email alerts are completely free, no card required, and there's no premium tier hiding behind it.
How many emails will I actually get?+
A handful a year — one when it's genuinely worth mowing, feeding, treating, or watering, and nothing in between.
What are the alerts actually based on?+
Real weather data for your ZIP code — soil temperature, rainfall, and evapotranspiration — run through the same model as our UK product, backtested against 86 years of weather data across 11 major US cities before this launched.
Do I need to install an app?+
No. Everything arrives by email.
Does it cover my area?+
Not yet everywhere — the US splits between cool-season and warm-season lawn grass, completely different growth biology, and only cool-season regions are validated so far. Enter your ZIP above to check, or see the state list below.
Can I pause alerts for No Mow May?+
Yes — tick the No Mow May option under advanced settings when you sign up, and mow alerts pause automatically for the month.
Can I get a photo diagnosis of a problem patch?+
Yes — once you're signed up, you can upload a photo any time for an instant AI diagnosis, checked against your lawn's actual current conditions. $1.99 per photo, no subscription — entirely separate from the free alerts.
