  • Space plants: 16 - 20 inches apart

Is there any one in Cairns successfully grow chillies Do you have to grow them in green houses or in the sun I have been told I will have to have a green house as it is to hot and wet Love to hear from a grower in Cairns Fred

I grow chili all year in Cairns. They do better if planted in the cooler months and the heavy rain in the wet season will kill smaller planta.

Look for when they say to plant. GROW in autumn/winter not summer.

I have that wrong with the melons etc. In tropics plant mid-late Autumn. In the sub tropics plant spring but you need to germinate the seeds in late winter- a problem with soil temps then as they are a little low. Germinate indoors in a warm area.

Hello. Does Chilli go out of season, if so, when?

Tammi - could be mice or rats, they can do this also. Its happened to me in Perth. Megan - Chillies will only grow vigourously during the warmer months, depending on where you are, they will either slow down, go dormant, or die altogether, depening on how cold it gets, a severe frowst will kill them. Wait until summer, they will flower all over, and give you lots of fruit. If you want a hotter chilli, water them less, let them dry out a little (but not all the way). A stressed plant will give hotter fruit. If you want hotter fruit still, get a different variety. Look for a chinense variety. Gareth - Most people raise chillies in punnets/starter pots, then into medium pots (10-15 cm across at the top), then onto final larger pots or garden beds when they have outgrown the medium one. You can tell when they are ready to be moved as they will have roots coming out the bottom. Julie - feed them with tomato food, probably in liquid form, is pretty good for flowering chillies, also, mulch and compost the soil if you can. Murray - depending on the variety, chillies can take up to 6 weeks to germinate, and they also need warm humid conditions to do so. Chillies are originally grown in warmer humid places, so they better you can recreate this, the happier they are. Keep them moist, (but not wet or soggy), perhaps put half a coke bottle over them to keep the humidity up, put them somewhere warm, they dont need sunlight to germinate, so the top of the fridge will do. When they do germinate, move them to a sunny windowsill or similar until they are ready to be hardened off to go outside. Michael - an NPK ratio of 10-5-10 for when they are growing works well, then 5-10-10 for flowering, if using bought fertilizers. Otherwise, a well composted mix of garden waste should work well, with some animal manure thrown in. Dont forget to mulch the soil to stop evaporation.
