City planting calendars

Planting Calendars by City

Each city page shows the frost dates for every ZIP code in the city, and its planting calendar uses one ZIP code’s own data: its nearest NOAA 1991–2020 freeze-data station, its 2023 USDA hardiness zone, and the planting dates our planner shows for that ZIP. Where frost is rare, the page uses the regional planting table the planner uses.
