  • 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 64°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 20 inches apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chillies.

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.

I am planning to plan habanero peppers and love in the north of Johannesburg. When is the best time to plant and how do I maintain? Thank you in advance

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.

It's April. Summer is over. My chillie bush has produced many chilliest. Now leaves are showing signs of withering. Does not look healthy. Is this normal as Winter approaches? Or is my plant being affected by some kind of fungus or disease?

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!
