Hi Matt (27th April 09). I have the same chillies growing as you do. Mine are called Firecrackers. I think they are the Firecracker Piquin from Capsicum Annuum family which i believe means you should keep some seeds if you want to grow them again. It may or may not survive til next year. A nice chilli though. We have been thoroughly enjoying the Black Pearl, Scotch Bonnet and White Habanero this season. Still got a few to ripen. Lucky the days in Perth are still sunny. The Jamaican Gold produced some beautiful looking fruit this year too and quite delicious!

I'm trying to work out what type of chilli plant i am growing, it was given to me, so i have no idea what variety it is. The chilli's seem to be pretty hot, they are about the size and width of your thumb from the knuckle down, they have a white flower and start off as a bright purple colour. As they mature they go a yellowish colour then to orange and finally red. I found a picture of what looks like a very similar plant called ABBRACCIO. But i cant find any more info on the net. Does any one know of a chilli fitting this description?

David, In their native Mexico, jalapeño peppers are eaten when they're green. Wikipedia has a useful article.

Like Ty (25/2/09), I too have small worms/grubs eating my chillies from the inside. Not sure what to spray them with.

Cliff. I have noticed my jalapeno chilli get a purple/brown ish tint before they start going red. It should start going redder in a couple (4) days

Tammi - could be mice or rats, they can do this also. Its happened to me in Perth. Megan - Chillies will only grow vigourously during the warmer months, depending on where you are, they will either slow down, go dormant, or die altogether, depening on how cold it gets, a severe frowst will kill them. Wait until summer, they will flower all over, and give you lots of fruit. If you want a hotter chilli, water them less, let them dry out a little (but not all the way). A stressed plant will give hotter fruit. If you want hotter fruit still, get a different variety. Look for a chinense variety. Gareth - Most people raise chillies in punnets/starter pots, then into medium pots (10-15 cm across at the top), then onto final larger pots or garden beds when they have outgrown the medium one. You can tell when they are ready to be moved as they will have roots coming out the bottom. Julie - feed them with tomato food, probably in liquid form, is pretty good for flowering chillies, also, mulch and compost the soil if you can. Murray - depending on the variety, chillies can take up to 6 weeks to germinate, and they also need warm humid conditions to do so. Chillies are originally grown in warmer humid places, so they better you can recreate this, the happier they are. Keep them moist, (but not wet or soggy), perhaps put half a coke bottle over them to keep the humidity up, put them somewhere warm, they dont need sunlight to germinate, so the top of the fridge will do. When they do germinate, move them to a sunny windowsill or similar until they are ready to be hardened off to go outside. Michael - an NPK ratio of 10-5-10 for when they are growing works well, then 5-10-10 for flowering, if using bought fertilizers. Otherwise, a well composted mix of garden waste should work well, with some animal manure thrown in. Dont forget to mulch the soil to stop evaporation.
