Know exactly when to overseed, aerate, and apply pre-emergent — for your ZIP code.
Generic lawn care advice tells you "fertilize in spring." That doesn't help when spring in Maine is May and spring in Georgia is February. We build a personalized 12-month calendar for your ZIP using NOAA climate normals and a soil-temperature model — and email you the PDF in under 60 seconds.
Free. No credit card, no upsell wall, no spam.
Care Calendar
How your calendar is built
ZIP → climate profile
Your ZIP resolves to lat/lon, USDA hardiness zone, and the nearest NOAA weather station. We pull 30 years of climate normals (1991-2020) from that station.
Soil temperature model
Air temperature alone won't tell you when crabgrass germinates. A damped-and-lagged thermal model converts air-temp curves to 2-4" soil temperature — the metric grass and weeds actually respond to.
Regional best-practice schedule
One of five region templates (cool-season north, transition zone, warm-season humid, warm-season arid, Pacific NW) provides the right monthly tasks for your grass type. Climate dates get injected for windows like pre-emergent and overseeding.
Personalized PDF in your inbox
A 16-page PDF with a cover, key-dates page, twelve month pages with prioritized tasks, and a reference card. Print it, pin it to the garage wall, or open it on your phone in the yard.
A look inside the PDF
Every task is prioritized. Critical items (the ones that determine whether spring goes well) sit at the top of each month with a personalized date window drawn from your ZIP's climate model.
The single most important spring application. Apply prodiamine when soil temperature is 50-55°F and BEFORE forsythia drops its blooms. Water it in with 0.25" within 7 days.
A modest 0.5-0.75 lb N/1000 sq ft once the grass is actively growing. Avoid heavy spring nitrogen — it pushes shoot growth at the expense of roots.
Pelletized calcitic lime if pH < 6.2. Up to 50 lb/1000 sq ft per year. Acts slowly — start now, retest next year.
FAQ
Why is this free?
We're testing whether people want hyperlocal lawn care timing. If signups happen, we plan to add an optional paid tier ($19-29/year) for real-time emails timed to actual weekly forecasts and modeled soil temperature — not just monthly averages.
What if you don't have a region template for me?
We currently cover the cool-season north, transition zone, warm-season humid south, warm-season arid southwest, and Pacific Northwest — about 95% of US lawns. Areas outside these (high mountain west, parts of Alaska) get the closest match. Hit reply on your welcome email and tell us where you are; templates get added by demand.
Do you sell my data?
No. We use your email to send the PDF and, eventually, an opt-in announcement of the paid tier. We don't sell it, share it, or use it for advertising.
How accurate are the dates?
The dates are 30-year-average estimates based on your nearest NOAA station — accurate to about ±1-2 weeks year to year. Weather is unpredictable; treat each date as the center of a window. The paid tier will narrow this to "do this task this week" based on actual current-year forecast and soil-temp models.
Will this work for commercial properties or HOAs?
The schedule logic is the same for any cool-season or warm-season turf. For commercial-scale operations we recommend the calendar as a baseline plus a turfgrass agronomist's local input. If you're an HOA or facility manager, reach out — we'd love to learn what gaps to fill.
