How do I grow chilli & pepper plants?

I've been given a pepper plant called Redskin and a chilli plant called Etna.

I have never grown either type of plant before and have no idea what to do with them! 

Are they happiest in the greenhouse?
Do they go in open ground, a pot or a grow bag?

Do I need to give them any special TLC?

Here's the Chilli:


and the pepper:


And have I lost it before I've started.... what are the black marks at the stem joints?


Any help greatly received.... don't let me kill them 

I am by no means an expert with chillies and peppers but am in my second year so will chuck in my 2 penneth!

They are easy chaps to grow, mine are planted in pots and last year lived outside tho they do need time to acclimatise so had them out for a few hours a day when it was sunny and eventually they were fine.

This year I have gone a bit mad and now have 25 living in the green house. They seem to prefer it there tbh its nice and warm and away from the slugs who seem to love them.

Dont over water them they are used to a hot climate and put their efforts into fruiting so I've been advised to let them almost dry out which is easy in a greenhouse!  
Add some tomorite to your water once a week and as they grow they will probably need some support as they can get top heavy.

However I will prob need to pollinate the flowers myself eventually they grow into a pretty bush which can be cut back and used the next year

Hope that helps - I'm sure someone far more experienced than me will be able to offer better advice!

Not sure what the black marks are but think its natural.......

They look really healthy plant. 

Just stick them in 8"-10" pots, perhaps add a cane for support. Feed weekly, with tomato food slightly stronger than normal. There's normally enough water in the tom food to keep them wet enough.

They're ornamental peppers so don't hide them away in the green house - they do like rather pretty covered in multicolour peppers.

They really need potting on ASAP though!!!

Not wanting to take away from this fantastic forum but if its Chilli information you want then have a little look on here... http://www.chillisgalore.co.uk/phpBB3/index.php

It was getting into growing Chillis that has led me onto veg growing and thus finding this superb forum!!
