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!
