We watch the soil temperature in your zip code and email you the moment it's time to put down crabgrass preventer — no guessing, no wasted product.
You sign up once. We do the watching. You get one email when it actually matters.
Email and ZIP code — that's it. No account, no password, no app to download.
Every day we check the actual soil temperature near you and the 8-day forecast.
One plain-English email: "It's time — put down pre-emergent this week." Done.
Crabgrass seeds germinate once soil temperature holds near 55°F. Pre-emergent has to be down beforethat — too early and it breaks down, too late and it's useless. The right week shifts by weeks depending on where you live and the weather that year. A calendar can't catch that. Soil temperature can.
Yes. The spring pre-emergent alert is free. We may later add an optional paid tier with a full year-round lawn calendar, but the core alert stays free.
About one a season for the core alert. We're not a newsletter — we email when it's time to act, and otherwise leave you alone.
Perfect — that's exactly who this is for. Drop your zip and we'll tell you what to do and when, in plain English.
We use research-grade soil-temperature data for your location and build in a safety lead time so you can act before germination. It's guidance, not a guarantee — always follow the product label.
Join free. We'll watch the soil and tap you on the shoulder at exactly the right moment.
