Feb 10 - We've planted a black pearl capsicum - stunning black foliage & fruit. Just harvested and deseeded the ripe fruit (red). I will try my hand at growing some more from seed. I make the mistake of not handling them with gloves, so my hands are still stinging. The brother in law's a chilli fan, but these'll blow his head off!

In the supermarket they all seem to have a bit of stem still attached, so they've been cut off. I normally cut them, as if they are ripe then pulling them will split the fruit and cover your hands with chilli juice.

Hey, I raised some plants in the seed tray (with lid) they grew very tall and thin over about 2 weeks. Still only 2 leaves and no real leaves. I put them outside for a bit and some shrivelled up. Was it too sudden a change for them?

Have planted various kinds of chilies. 1- Habaneros are ornage when ripe but not hot at all. Anyone can explain why? 2- Something is eating the leaves of my Thai chilies. Plant is almost bald. Have used pyrethrum spray & snail/slug pellet but to no avail. Any idea what the mystery pest is & what can I do? 3- What's the best way to prune chili plants? Thanks & Happy gardening, y'all! :-)

Have planted some chilli plants from seedling in pots about a month ago. Plants are about 40 - 50cm tall. The are very slow at producing flowers compared to a mates plants. He isn't doing anything different to me. Any tips to get flowers and fruit?

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!
