Can you grow chillies from seed in New Zealand?

Yes, you can grow chillies from seed in New Zealand, and it's easier than most people expect. The main thing that trips growers up isn't skill, it's cold. Chillies are heat-loving plants, so as long as you give the seeds enough warmth to germinate and a long enough season to fruit, they grow happily here from top to bottom of the country.

Start them indoors

New Zealand's a bit cool for sowing chillies straight into the ground, so nearly everyone starts them off indoors in late winter or early spring. You're aiming to raise strong seedlings inside while it's still cold out, ready to plant into the garden once the frosts have gone and the soil's warmed up.

Sow into trays of moist seed-raising mix, about 5mm deep. Keep them somewhere warm and bright.

Warmth is the whole game

This is where most first-timers come unstuck. Chilli seeds respond to soil temperature, not air temperature. A tray on a cold windowsill in winter is well below what they need, so the seeds just sit there doing nothing, and people assume the seed was dud when it was only cold.

Aim for soil warmth around 25 degrees. A heat mat under the tray is the easiest way to hold it, but the top of the fridge or a hot water cupboard works too. Get that right and most varieties are up within one to two weeks. Superhots are slower and fussier, so give those extra patience.

Growing them on

Once your seedlings have their first true leaves and have put on a bit of size, pot them up so the roots have room. When the frosts have passed, harden them off and plant them out into their final spot, whether that's a garden bed or a decent-sized pot. Chillies need full sun to ripen their fruit, so give them the warmest, brightest position you've got.

From there it's steady watering, a regular feed once they're established, and time. Everyday varieties will fruit within a few months of transplanting. Superhots take a good deal longer, which is why they go in first.

The short version

Warm soil to germinate, a sunny frost-free spot to grow, and the right variety for the time you've got. Do that, and growing chillies from seed in New Zealand is genuinely straightforward. The hardest part is waiting.
