November in Zone 12 is the cool dry season begins gardening, and it rewards gardeners who plant to the season rather than fighting it. This guide covers what to plant in november zone 12 — what to sow, what to start indoors, what to transplant and what to harvest in Zone 12 in November — using USDA zone averages and published crop ranges, so you can plan with confidence and check the details against your local extension service.
What November means in Zone 12
Zone 12 is frost-free, with average winter lows of 50 to 60°F. Nights rarely feel cold at all, and tropical plants grow year-round with only a gentle slowdown in the coolest months.
November opens the cool dry season — the most reliable growing window in the tropics. Days are warm and sunny, nights are pleasantly cool, humidity falls, and cool-season vegetables grow at their best with far less disease pressure than summer.
Frost dates are given here as zone averages, not exact dates for any garden. Zone 12 is frost-free, with average winter lows of 50 to 60°F.
Your November task list
- Sow the full cool-season range and keep sowing salads in succession.
- Transplant tomatoes, peppers and eggplant started indoors into sunny beds.
- Water deeply in the morning; dry-season wind dries the top of the soil fast.
- Feed brassicas with compost as they head up — hungry crops need feeding.
Work through that list in order if you are short of time: sowing and transplanting first, because they are time-sensitive, then feeding and mulching, then tidying.
What to start indoors in November
Starting seeds indoors gives slow crops a head start and protects young seedlings from heavy rain, wind and pests. In Zone 12 in November, the indoor sowings worth making are:
- Tomatoes — tender, start indoors; germination 7–14 days, maturity 60–85 days.
- Bell Peppers — tender, start indoors; germination 7–14 days, maturity 60–90 days.
- Eggplant — tender, start indoors; germination 7–14 days, maturity 70–85 days.
- Basil — tender, start indoors; germination 5–10 days, maturity 60–70 days.
Use clean trays and fresh seed-starting mix, keep the mix moist but never soggy, and give seedlings as much light as you can — a bright windowsill is a minimum and a simple grow light is better. Use the watering calculator to plan this month's seedlings before they go outside.
What to direct-sow in November
Direct sowing suits crops that dislike transplanting, or that grow fast enough not to need a head start. In November in Zone 12, sow these straight into prepared beds:
- Lettuce — hardy, both; germination 7–10 days, maturity 45–60 days.
- Carrots — hardy, direct sow; germination 14–21 days, maturity 60–80 days.
- Peas — hardy, direct sow; germination 7–14 days, maturity 60–70 days.
- Radishes — hardy, direct sow; germination 4–7 days, maturity 25–40 days.
Sow into moist soil, cover to the depth on the packet, and keep the seed bed damp until germination — in warm weather that can mean watering lightly twice a day for the first week. Thin seedlings to the spacing in the table below; crowded seedlings grow thin and weak, while properly spaced plants grow into the full harvest the packet promises.
What to harvest in November
November harvests in Zone 12 reward the sowings of the last one to three months:
- Broccoli
- Cauliflower
- Sweet Potatoes
- Tomatoes
- Lettuce
- Cilantro
Harvest in the cool of the morning when leaves are crisp and flavours are at their best, and pick little and often rather than letting everything mature at once. Leafy crops regrow after picking if you take outer leaves and leave the centre growing, and fruiting crops such as tomatoes, beans and cucumbers produce far longer when picked regularly.
Frost and cold protection in Zone 12
Frost is not a normal concern in Zone 12, so frost protection is mostly about rare cold snaps and wind. The coldest nights of the year may dip into the 50s, which is enough to slow basil and chill young tropical seedlings but not to kill established plants. The real protection jobs here are different: shade cloth for cool-season crops in warm months, windbreaks against salt-laden or drying winds, and drainage so heavy tropical rain does not drown roots.
November planting data
The table below uses published ranges from standard horticultural references — germination and maturity vary by variety, soil and weather, so treat them as guides, not guarantees.
| Crop | Germination (days) | Maturity (days) | Spacing | Cold tolerance | Sowing method |
|---|---|---|---|---|---|
| Lettuce | 7–10 | 45–60 | 8–12 in | hardy | both |
| Carrots | 14–21 | 60–80 | 2–3 in | hardy | direct sow |
| Peas | 7–14 | 60–70 | 2–3 in | hardy | direct sow |
| Radishes | 4–7 | 25–40 | 2–3 in | hardy | direct sow |
| Tomatoes | 7–14 | 60–85 | 24–36 in | tender | start indoors |
In Zone 12, think of the year as a long tropical season with a short, mild cool season inside it.
Watering, soil and pests in November
With lower humidity, fungal problems ease, but aphids and caterpillars still find young brassicas. Check under leaves weekly and hand-pick before numbers build.
Watering in November should be deep and at the base of plants, in the morning where possible, so leaves dry before nightfall. In the dry season that means a thorough soak a few times a week rather than a daily sprinkle; in the wet season it often means watering hardly at all and watching drainage instead.
Looking ahead
December stays cool and dry, so the same sowings continue — it is the easiest month of the year to keep a salad garden going. For the full year, browse the planting calendar hub and compare the same month across zones — the neighbouring months in your batch are a good place to start:
- October in Zone 12 — the same month in a neighbouring zone, for comparison.

Frequently asked questions
What can I plant in November in Zone 12?
Lettuce, carrots and peas are good direct sowings in November in Zone 12, and tomatoes, bell peppers and eggplant are worth starting indoors. Zone 12 is frost-free with average winter lows of 50 to 60°F, so the main limit in November is heat and rain, not frost — check your local extension service for varieties suited to your area.
Is Zone 12 frost-free?
Yes, Zone 12 is frost-free in USDA averages, with winter lows of 50 to 60°F. That is an average, not a guarantee for any single garden or year, and a rare cold snap can still chill tender tropical plants — keep frost cloth or old sheets handy and check your local extension service for your area's actual cold history.
When should I start tomato seeds in Zone 12?
Tomatoes take roughly 60–85 days to maturity and germinate in about 7–14 days, so start them indoors and transplant sturdy seedlings into warm soil. In the cool season that usually means starting indoors in the autumn and winter months; in the hot wet season, grow them where they get morning sun and good airflow, and use the seed-starting calculator to work back from your transplant date.
What should I harvest in November in Zone 12?
Broccoli, cauliflower and sweet potatoes are typical November harvests in Zone 12, from sowings made one to three months earlier. Harvest in the morning, pick little and often, and use the days-to-maturity ranges in the table above to judge when each sowing should be ready.
How do I keep cool-season vegetables going in Zone 12?
Sow them in the coolest months, choose fast-maturing varieties, give them afternoon shade and plenty of water, and harvest young before heat makes them bolt. In Zone 12 the cool-season window is short — especially in Zone 13, where it is more of a brief trial than a full season — so succession sow every two weeks while conditions suit them.
