S = Plant undercover in seed trays P = Sow seed

  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 64°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 20 inches apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chilies.
  • Compatible with (can grow beside): Best grown in a separate bed as chillis need plenty of light and air circulation.
  • Small, hot, chilli

Small bushy plants. Dark green ovate leaves.

Chilli need warm frost free weather, so protect with glass or plastic covers if planting outside in cooler areas.

Most varieties need a long growing period to produce many fruit.

There are many types of chilli. Some are more fiery than others. As a general rule, the smaller the pod the hotter the taste.

Culinary hints - cooking and eating Chilli peppers

Chillis freeze very well. Wash, dry, and free whole. Use them direct from the freezer (no need to defrost).
Wear plastic gloves or wash your hands thoroughly after handling and cutting to avoid accidentally rubbing chilli juice onto your mouth or eyes!

Can they grow in a green house

Probably depends what you line it with. Plastic might make it too hot, shade cloth might cut out too much sunlight, maybe insect netting is the go. They grow chili in Bundaberg (sub tropical) out doors.

About chilli peppers If you see the leaves have got burnt with frost better to harvest all chilli and grind in food processor or leave it whole and store in the freezer and use it when needed. Trim the trees heavily ie only leaving about 30 centimeters above ground. It will or may grow back in summer. You can add some mulch around the plants too. Seeds can only be obtained from ripe chilli. It’s much better to buy plants and grow them then trying to plant from seeds. Plant after Labour weekend only if the soil is not too cold.

My question is I'm in Queensland Brisbane wanting to grow chilli seeds over the winter ready for summer if I use a heat mat will that be sufficient enough to get them ready for summer

Think about whether you live in a frost free, then read the above again. Time to plant what temperature you need, time it takes to grow. It is all there.

I'm in Melbourne and grew chili seeds over winter successfully just by putting the pot in a sunny window over winter, then planted them outside in late spring. If that works down here it should work up there without a heat mat too... :)

G'day Adrian. I tried with the heat mat last year and did not get a very good result and a late crop. Having said that I now have 1.2m tall Carolina Reaper, Moruga Scorpian and Bhut Jolokia from which I will be striking cuttings for next season to increase production. I have previously got from three to five years cropping from well cared for and fed plants.

John, my son has had trouble getting his hot hot chilli seeds to germinate also, and he too used a heat mat. Not being accustomed to subtropical growing of anything, can you make a suggestion as to why this seems to be a feature of the hot varieties of chilli?
