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.
