Orlando, Florida is in USDA plant hardiness zone 10a. Its average last spring frost is around January 25 and the first fall frost around January 10, giving a growing season of about 355 days (NOAA 1991–2020 normals, 32°F, median). Start tender crops like tomatoes and peppers indoors weeks before the last frost and set them out afterward; sow hardy crops such as peas, spinach, and lettuce before it. The planner below turns those frost dates into a printable per-crop planting calendar.
Orlando planting calendar
Each crop's windows are counted from Orlando's average frost dates. hatched = start seeds indoors, solid green = plant out, teal = a fall sowing, and the terracotta dot marks the estimated first harvest. Ranges are extension-guide planning guidance, not guarantees.

Frost & freeze dates
From NOAA's 1991–2020 Climate Normals at station USW00012815. The median (p50) is the average date; the 90%-safe column is the date the freeze has passed in about 9 years out of 10 (p10 for spring, p90 for fall) — the conservative date to plant after or harvest before.
| Threshold | Last spring — avg | Last spring — 90%-safe | First fall — avg | First fall — 90%-safe | Season (days) |
|---|---|---|---|---|---|
| 36°F | Feb 5 | Mar 9 | Jan 1 | Jan 31 | 326 |
| 32°F (freeze) | Jan 25 | Feb 26 | Jan 10 | Feb 10 | 355 |
| 28°F | Jan 16 | Feb 9 | Jan 13 | Feb 5 | 365 |
| 24°F | — | — | — | — | 365 |
32°F is the standard "freeze" line that damages tender crops; lighter 36°F frost can nip the most cold-sensitive plants, while hardy crops shrug off light frost down toward 28°F. Use the threshold that matches what you are protecting.
Growing degree days
Growing degree days (GDD) accumulate warmth above a base temperature over the year — a better predictor of crop development than the calendar alone. Warm-season crops need a long, warm GDD total; a short, cool GDD total favors greens and brassicas.
| Model | °F·days | Used for |
|---|---|---|
| Base 50°F (warm-season) | 8,428 | standard warm-season base (tomato, corn, beans) |
| Base 40°F (cool-season) | 12,053 | cool-season crops (brassicas, greens) |
Hardiness zone 10a
Orlando sits in USDA plant hardiness zone 10a on the 2023 map — meaning its average annual extreme minimum winter temperature is about 30 to 35 °F. That number tells you which perennials, shrubs, and trees reliably survive an average winter here; it does not set your planting dates, which come from the frost calendar above.

Frequently asked questions
- What USDA hardiness zone is Orlando?
- Orlando, Florida is in USDA plant hardiness zone 10a on the 2023 map (average annual extreme minimum temperature 30 to 35 °F) — from the USDA Plant Hardiness Zone Map 2023, matched to this location's ZIP. See the methodology page for sources.
- When is the last frost in Orlando?
- The average (median) last spring frost at 32°F is around January 25, from NOAA's 1991–2020 climate normals at the nearest reporting station. Roughly one year in ten the last frost is as late as February 26, so wait until then before setting out frost-tender plants if you want to be safe.
- When is the first fall frost in Orlando?
- The average first fall frost at 32°F is around January 10. That leaves a growing season of about 355 days between the average last spring and first fall frosts.
- When should I start tomatoes in Orlando?
- Start tomato seeds indoors about Jan 1 and transplant them outside about Feb 1 – Feb 8, once the danger of frost has passed. Estimated first harvest is around Apr 2 – Apr 22.
- How long is the growing season in Orlando?
- About 355 days at the 32°F threshold (NOAA 1991–2020, median) — the span between the average last spring frost (~January 25) and the average first fall frost (~January 10). Cold-hardy crops extend usable time at both ends; frost-tender crops fit inside it.
