Planting calendar

When to plant — by crop and US state

Pick a crop, then your state, for exact sow, transplant, and harvest dates. Every one of these 2485pages derives its timing from the crop's real frost tolerance and that state's USDA zone frost window — a Florida tomato calendar is genuinely different from a Minnesota one.

How the timing is calculated

Each crop carries a frost-tolerance class and sowing offsets (weeks indoors before last frost, days to transplant relative to last frost, days to harvest). Each state carries its dominant USDA hardiness zone and average last-spring and first-fall frost dates. We combine the two: warm-season crops in cold states get an indoor-start date and a post-frost transplant date; cool-season crops go in before the last frost; garlic is timed off the first fall frost; and warm-state pages (Florida, Texas, Arizona desert) switch to the local two-season model — a spring crop and a fall crop around a deliberate mid-summer heat break.
