Tool
Planting calendar by ZIP code
Personalized sow, transplant, and harvest dates for 69 frost-dated crops, built from your USDA hardiness zone and your nearest weather station's frost dates.
A personalized year
Sow, transplant, and harvest bands for 69 frost-dated crops on one visual timeline, shifted to your dates.
Your real frost dates
Pulled from your nearest NOAA station's 1991-2020 freeze normals, not a generic zone average.
Sourced, not guessed
Every crop's window traces to a named university extension publication.

Common questions
How are these planting dates calculated?
We take your ZIP code's USDA 2023 hardiness zone and the 1991-2020 freeze-date normals from your nearest NOAA weather station, then shift each crop by its planting window from university extension publications. Nothing is hand-typed per crop.
What does the frost risk setting do?
It picks how conservative the frost date is. Cautious uses the date by which a late frost is unlikely (only a 10 percent chance one comes later), so you wait longer and risk fewer losses. Optimistic plants earlier and accepts more risk. Typical year is the median.
My area never frosts. What happens?
If your nearest station shows no reliable freeze, frost-anchored timing does not apply and we say so. Plant by soil temperature and season instead; see each plant guide.
