(Best months for growing Chilli peppers in Australia - sub-tropical regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • 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
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chillies.
  • Compatible with (can grow beside): Best grown in a separate bed as chillies need plenty of light and air circulation.

You can grow in a pot, make sure it is a big pot. If chilli is going to grow 50cm make the pot that wide also.

Look at the monthly calendar at the top of the page, set your climate zone, it tells you the best months to start planting - NOV.

I live in the Eastern Cape and my mom makes and sells chilli paste. I am thinking of growing the chillies ourselves because it can get difficult to find chillies. What advice do you have to make sure that we always have chillies growing? I will be making wooden creates / boxes to grow the chillies in, because the soil on our land is not very fertile if I grow but it will be outside and in the boxes I can move them around for different times of the year where the sun will be catching best.

I feel you would have more chance of a good crop if you planted in the ground than in boxes or crates. They need to be in sunlight all/most of the day. They are a spring through autumn crop I think, I have never grown them. You need to improve your soil by adding compost and manures regularly, yearly. Soil is only the medium that plants grow in. All soils need to have nutrients added to them, compost, manures, mulch that breaks down, fertilisers etc. Do some internet research on how to grow them.

Best is to plant a new chillie plant.i had a plant which survived winter but did not gave as much fruit as it did before.

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.

Wait until it says when to plant is a good idea. The guide here says this is the best time to grow it, to give yourself the best chance of a good crop. Now you can start a little earlier or later but you may not produce as good a crop. Then you have to take your weather/climate conditions into considerations. This website isn't spot on all the time. They might say plant beans from fall (autumn) to spring, but the bean fly kill mine in autumn so I only plant in the spring. Where I live it says grow egg plant in warm weather, spring to late autumn. I have picked it all through winter. Sometimes it is all about trialing things or just having a go.

I don't mean to be rude, but would like to clarify a few things that have been said here, and give a bit of information. The Bhut Jolokia is supposed to be ~1.5 million Scoville units in heat and is realistically about 1 million, compared to a Habanero, which is usually ~300,000 Scoville units. The habanero is too hot for most, and the Bhut Jolokia is only for the diehard Chilliheads. Scotch Bonnets, Habaneros, and Bhut Jolokias are all Capsicum Chinense, whereas the standard chillies (pointy-ended ones) are Capsicum Annuum, and are usually alot more mild. Sweet Bell Peppers (Capsicums) are C. Annuum, and can cross-pollinate with other Chillies. Kate - Chillies are usually fairly slow-growing plants compared to things like Tomatoes etc. Right now, it may be too cold for them to be in full swing. The flowers are self-fertile, so will pollinate themselves, but you need to help them along by sticking pollen to the Pistil using a cotton bud or similar. Swirling your finger around gently inside the flower works too. When the fruit is pollinated, the flower will go brown, and drop off, and the fruit should start growing. Flowers browning and dropping could also be due to a poor feeding regime. On most (all?) fertiliser bottles you will see a NPK number set. N=Nitrogen, P=Potassium, K=Phosphorus. General vegetative growth (leaves/stems) is encouraged by high-N analysis fertilisers, and flowering is encouraged by high P/K analysis fertilisers. At this time of year, I have my chillies inside on shelves in front of a large west-facing window. Usually, I find that if the overnight low temperature drops below about 5 degrees C then they will stop growing/flowering. I would try and be patient with your Capsicums and Chillies. As they are already established, you should get a good head start this season. Good luck!
