Guess less.
Frost dates from NOAA's 1991–2020 climate normals and zones from the USDA hardiness map, turned into the answer you actually wanted: can I still plant this?

4 tools that cover the year
Between them they answer the season from both ends — when to start, when to sow again, what still fits, and what lives through the winter. 32 vegetables and 74 perennials.
- What can I still plant? Counts the growing days left before your first fall freeze and tells you, crop by crop, whether there is still time.
- What survives my winter? Reads your USDA hardiness zone and works through the perennial fruit, berries, vegetables and herbs that live through it — and the ones that fail for being too warm.
- When do I start my seeds? Anchors on your last spring freeze and dates every spring job — sow indoors, set out, direct sow — for 32 vegetables.
- When do I sow the next round? Works out how often each crop is worth re-sowing and when the next sowing is due — and, where summers are hot, which sowings would only bolt.

Guides for 388 US metro areas
Each one names every NOAA station that serves it, with its own freeze-date range and spring calendar. 91 sit inside a single hardiness zone and say so outright; the other 297 show how the answer changes across them.

- A dated calendar
Sow indoors, set out, direct sow — from your own last freeze.
- Heat, not just frost
Where summers bolt cool-season crops, the tools hold the sowing.

Planting zones by state
Every state spans several hardiness zones — not one of the 52 falls inside a single one — so each page gives the split across zones by ZIP code, the spread of freeze dates across the NOAA stations inside it, and the metro areas it contains.

The data underneath
Where every number comes from
- NOAA stations
- 7,125
- Each publishing freeze normals. Old Farmer's Almanac advertises 6,000+.
- ZIP codes
- 40,502
- With a USDA 2023 hardiness zone. 33,394 are matched to a station within 100 km.
- Median station distance
- 11.9 km
- Shown on every result, because a distant station is a different climate.
Nothing here is estimated or interpolated. Where a location has no station close enough to describe honestly, the tool says so and shows no frost date rather than a number you would reasonably assume was local. More about how this is built.
