Short answer: November is the temperate zone's frost-tender floodgate — the frost period finally closes, and five crops (climbing beans, courgette, pumpkin, Jerusalem artichoke and yacon) all open their sowing windows for the first time this year. At the same time, broccoli, coriander and tomato's sowing windows are closing, basil and cucumber start transplanting, and the harvest list is the longest of the year so far.

The NZ Temperate November Growing Context

The frost period runs April through November, so this is genuinely the last month of frost risk — not just "risk easing" as it was in September and October. That's why so much opens at once: courgette, pumpkin, beans and the two perennial tuber crops are all frost-tender direct-sow crops that have been waiting for exactly this month.

Typical November conditions in temperate gardens:

  • Frost period closes at the end of the month — the last of the calendar's frost risk
  • Five new sowing windows open at once, all frost-tender
  • Basil and cucumber start transplanting; broccoli and tomato continue
  • Broccoli, coriander and tomato's sowing windows close this month
  • Twelve crops in active harvest — the broadest list of the year so far

What to Sow This Month

Courgette and Pumpkin — the headline warm-season crops

Courgette's window opens in November and runs through February; pumpkin's opens now too but runs only to January, reflecting its much longer ~100–160 day season. Both are direct sown once frost risk has genuinely passed — courgette needs at least two plants a metre apart for reliable pollination, while pumpkin needs real sprawling room and dislikes root disturbance, so it's sown in place rather than raised in trays.

Cultivar picks: Black Beauty (Kings Seeds NZ) for courgette; Atlantic Giant (Kings Seeds NZ) or Austrian Hulless (Koanga Institute) for pumpkin.

Climbing Beans

Beans open this month too, sowing through to February for a harvest running February–May. Direct sow after frost risk has passed and get a support structure up before the plants need it — beans put on height fast once they get going.

Cultivar picks: Anasazi (Kings Seeds NZ), direct sown; or America (Koanga Institute), started in trays and transplanted at 10cm spacing under trellis to dodge birds, slugs and cold-ground rot.

Jerusalem Artichoke and Yacon — perennial tuber crops

Both open this month and close at the end of December, planted as tubers or crown divisions once soil has warmed past roughly 15–16°C rather than sown as seed. Pick a semi-permanent spot for either — Jerusalem artichoke in particular regrows from any tuber left behind, so treat the bed as a multi-year commitment, not an annual one. Koanga Institute is the only supplier with any record of either crop, and the exact month boundaries are this project's own frost-anchored judgment rather than a directly sourced figure, so treat November–December as a reasonable window rather than an exact cutoff.

Last call: Broccoli, Coriander and Tomato sowing

  • Broccoli — sowing closes at month end, open since August. Egmont lists a second Feb–May window not covered here if you miss this one.
  • Coriander — closes at month end, open since July. Sow now if you haven't already; it bolts fast once the weather warms further.
  • Tomato — sowing (not transplanting) closes this month. If you haven't started seed by now, buy seedlings instead.

Still open

Beetroot, carrot, lettuce, mizuna, pak choy, peas, radish, silverbeet and spinach all continue from earlier months — nothing new for these this month, but all remain sowable.

Transplant This Month

Basil and cucumber both start transplanting this month, both frost-tender crops that were raised in trays and can now safely go outside. Basil's transplant window runs through February, cucumber's through February as well — harden off trays for a week or two in a sheltered spot before moving either into open ground.

Broccoli (transplanting since September) and tomato (since October) continue. Brussels sprouts, transplanted since October, close out this month — get any remaining seedlings in now.

What to Harvest This Month

  • Garlic — coming into harvest this month and next, roughly seven months after planting.
  • Kale — harvest continues into January; flavour actually improves after frost.
  • Mustard Greens — ready this month and next from the October transplant.
  • Turnip — last call for harvest; it dislikes summer heat, so pull what's left rather than letting it sit into December.
  • Beetroot, Silverbeet, Lettuce, Spinach, Radish — all comfortably within their harvest windows.
  • Coriander, Mizuna, Pak Choy — cut-and-come-again from earlier sowings; take outer leaves rather than whole plants.

Garden Jobs for November

Get support structures up before the sprawl starts

Beans need a trellis, and pumpkin and courgette both need the space they'll eventually sprawl into marked out now — fitting a support or clearing ground around an established plant later risks damaging roots and stems.

Clear the last-call crops as they finish

Broccoli, coriander and tomato all close their sowing windows this month, and turnip closes for harvest. Use the freed bed space for this month's new frost-tender sowings rather than leaving gaps.

Common November Mistakes

Treating "frost period closes" as "frost risk is zero"

The frost period ends on the calendar at the close of November, but an isolated late frost the first week of December isn't impossible. Watch the forecast for new transplants rather than trusting the date alone.

Sowing tomato from seed this late

Tomato's sowing window closes this month for a reason — seed started now won't catch up to seedlings sown back in August or September. Buy seedlings instead if you're starting late.

Looking Ahead

December pushes courgette, pumpkin and beans toward their first flowers, while garlic and kale continue their harvest run. Beetroot, carrot, lettuce, mizuna, pak choy, peas, radish, silverbeet and spinach all keep going regardless, still inside their long sowing or harvest windows from earlier in the year.
