Greenly Garden

When to plant tomatoes in New Zealand: 26 October – 29 February

Tomato in New Zealand: plant out into open ground from 26 October to 29 February; the window opens earliest in Hamilton (New Zealand) and closes latest in Palmerston North (10 cities).

Each window starts on the Greenly calendar date and ends on the last day that still leaves the crop’s days to harvest (from its card) before the average first autumn frost, plus six weeks of picking for crops harvested over weeks (tomatoes, peppers, aubergines, cucumbers, courgettes, pumpkins, watermelons, beans) — our rule; earlier in the window is safer.
