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.

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 seven region templates (cool-season north, PNW, mountain west, transition zone, warm-season humid, warm-season arid, California coastal) 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.

Real-time emails. Not 30-year averages.
Right now, your free calendar uses 30-year NOAA climate averages — the dates are typical for your ZIP, but not for this year.
Weekly-email subscribers get emails that pull their actual local forecast, real-time soil temperature, and current-year weather to tell them exactly what to do this week — not "around April 10."
$4.99 / month. Cancel anytime. The free 12-month calendar always stays free for everyone.

FAQ
Why is this free?
The free calendar gives every homeowner a useful 12-month plan. The optional $4.99/month weekly subscription adds a current National Weather Service forecast and a prioritized Monday briefing.
What if you don't have a region template for me?
We currently cover cool-season north, cool-season Pacific Northwest, cool-season Mountain West, transition zone, warm-season humid south, warm-season arid southwest, and California coastal Mediterranean — about 99% of US lawns. Areas outside these (parts of Alaska, Hawaii) get the closest match. Hit reply on your welcome email and tell us where you are; new templates get added by demand.
Do you sell my data?
No. We use your email to deliver the calendar and any subscription emails you request. We don't sell it, share it for advertising, or use third-party advertising cookies.
How accurate are the dates?
The PDF dates are 30-year-average estimates based on your nearest NOAA station. Weather is unpredictable, so treat each date as the center of a window. Weekly subscribers also receive current seven-day forecast context.
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.
