Don't be in a rush to get the seeds out. This year we've got a cold winter, so if you are sowing directly into the ground I would not sow earlier than mid September in Jhb North just to be safe. If you can start the seeds indoors you could sow early August, and plant out mid September. Plant in full sun at least 50cm apart. Make sure your plants don't dry out or your harvest will be affected. The best way to do this is to mulch well with organic matter around the plants (leaves, compost etc) to prevent moisture loss / keep moisture levels constant, but you will still need to water. When you see flowers develop, feed with a small handful (per plant) of Vita Veg Fruit & Flower - don't dig it in, just sprinkle around the plant. Leave your bushes to overwinter, they might survive!

It says plant seeds in Sept. Probably for soil temperature reasons. You could start inside in August but would have to provide warmth for them to germinate. Put them outside as soon as they germinate otherwise the might grow leggy, very tall and thin, looking for sunlight.

I bought a chilli plant, very small, and it grew into a lovely plant, heaps and heaps of chilis. My question, will it flower again each year and produce new fruit each year? Or do I throw it away, and plant a new one?

I try to take my chillie plants through the winter by protecting from frost and the ones that survive do really well, better than new plants, so I would try to keepit going

i have a jelopeno plant that is 5 years old (in a large pot ) It still produces chillies ..loads of them Its a small tree if you google it. produces mostly smaller fruit but . it does yield a few large ones ( probably more then a younger plant will ) pruning it back, sometimes pulling off the new buds, will transfer the energy back into the plant. of course using the right fertilizer, minerals and Nutrients will also help the plant survive overwintering looks like its dead. But it is survivable if done right

Best to google it and read up. Can be annual or perennial.

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!
