Know before you mow
We watch real weather for your postcode 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.

How it works
Three steps to set up. Then we do the watching.
Drop in your postcode
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.

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 postcode — soil temperature, rainfall, and evapotranspiration — run through models checked against 86 years of UK weather history. Not a generic ‘mow weekly from March’ calendar.
Do I need to install an app?+
No. Everything arrives by email. If you'd rather check in yourself, the live forecast page tracks the same model across UK towns and cities.
Does it cover my area?+
Turf Alert works UK-wide — enter any postcode at signup and we'll match it to the nearest weather data. You can browse coverage on the forecast page too.
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.
