Vegetable planting calendars by state (2027)

Frost dates and planting windows for 27 vegetables and herbs in every state and DC, for the state capital and its largest city, plus a third city where the state's planting tables change. The dates come from NOAA's 1991-2020 frost normals and the planting rules of university extension guides, the same data the Rowtime app uses.

Rowtime: Garden Planner works these dates out for your own ZIP code in the US, shows where each one comes from, and recalculates when a planting slips. Get Rowtime on the App Store.

Dates are estimates. Check your local extension office before you plant, and use your own frost records if you have them.
