Brandon, Florida is in USDA plant hardiness zone 9b. Its average last spring frost is around January 30 and the first fall frost around January 6, giving a growing season of about 335 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.
Brandon planting calendar
Each crop's windows are counted from Brandon'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 USC00087205. 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 16 | Mar 17 | Dec 25 | Jan 22 | 303 |
| 32°F (freeze) | Jan 30 | Mar 2 | Jan 6 | Feb 5 | 335 |
| 28°F | Jan 20 | Feb 10 | Jan 11 | Feb 4 | 365 |
| 24°F | Jan 9 | Jan 29 | Jan 8 | Jan 27 | 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) | 8,907 | standard warm-season base (tomato, corn, beans) |
| Base 40°F (cool-season) | 12,537 | cool-season crops (brassicas, greens) |
Hardiness zone 9b
Brandon sits in USDA plant hardiness zone 9b on the 2023 map — meaning its average annual extreme minimum winter temperature is about 25 to 30 °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 Brandon?
- Brandon, Florida is in USDA plant hardiness zone 9b on the 2023 map (average annual extreme minimum temperature 25 to 30 °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 Brandon?
- The average (median) last spring frost at 32°F is around January 30, from NOAA's 1991–2020 climate normals at the nearest reporting station. Roughly one year in ten the last frost is as late as March 2, so wait until then before setting out frost-tender plants if you want to be safe.
- When is the first fall frost in Brandon?
- The average first fall frost at 32°F is around January 6. That leaves a growing season of about 335 days between the average last spring and first fall frosts.
- When should I start tomatoes in Brandon?
- Start tomato seeds indoors about Jan 1 and transplant them outside about Feb 6 – Feb 13, once the danger of frost has passed. Estimated first harvest is around Apr 7 – Apr 27.
- How long is the growing season in Brandon?
- About 335 days at the 32°F threshold (NOAA 1991–2020, median) — the span between the average last spring frost (~January 30) and the average first fall frost (~January 6). Cold-hardy crops extend usable time at both ends; frost-tender crops fit inside it.
