September: After risk of frosts

  • 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 18°C and 35°C. (Show °F/in)
  • Space plants: 40 - 50 cm apart

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?

Hello. What happens if I leave ripe chilies on the plant. Is there a risk they will start to rot? I have a few that seem to be starting to soften in places and splitting ?

Yes they will rot best to pick when ripe and freeze

I have a medium size Chilli plant that has been in the ground now for the summer period but it hasn't produced a single fruit. It is only starting to flower. I have never tried growing Chilli before so I have a few questions 1. When/what month should I expect some chilli's?(Summers finished here) 2. Are the flowers the base of the chilli's pod? 3.What can I use use to stop moths/bugs eating the leaves? TIA

Read the notes here. Plant during the summer. Has a long growing season. Take 9-11 weeks to produce fruit. Needs warm and airy space. 1. Flowers will produce chilli I presume. 2. Yes the chilli should come from the flower pod. 3. Look up a spray on the internet for spraying chilli. Or put bird netting over it.

Hello, I want to grow chili peppers (Scotch Bonnet) soon but I see that it may be outside of the growth period. What advice would you give? I live in Long Beach, CA.
