Vegetable Planting Calendar by Location

Start with local freeze probability, then translate it into what to start indoors, set outside, or direct sow now.

How the calendar works

The local climate anchor is NOAA’s cautious 10% last-32°F-freeze date when available. Crop biology is stored separately. Warm crops are held back when the current NWS forecast still contains freezing temperatures.

The date is a planning anchor, not a guarantee. Local cold pockets, elevation and soil temperature still matter.

Crop timing is sourced separately

Indoor growing duration and frost-relative set-out timing are based on Cooperative Extension schedules, including University of Maryland Extension, Oregon State University Extension, University of Maine Extension, and Rutgers Cooperative Extension.
