Yes like tomatoes and peppers they go red when ripe.....

I dont grow chillis but the seed catalogues do have fun decripions like atomic, inferno, prarie fire etc

Also south devon chilli farm could be good place to start, try googling

Thanks Pamg. I have now been on this website. I would really like to grow different types of peppers all year round!

Couldbe fun next year, I prefer sweet peppers, the long ones are lovely roasted or barbecued
Have fun choosing ?

Some tend to go black before turning red.

Thanks Littlelegs. I'll watch out for this. They are all green at the moment. Does anyone know how long it takes for them to turn red? I don't want to leave them for too long in case they rot.

Keep an eye on them, bring them indoors if it turns cold, bananas are supposed to help things ripen, they'll go streaky first

Its an age thing too, maybe start them earlier if you can keep them warm enough
