Thanks to all the Chile Heads for their responses to my question about Scotch Bonnets ripening. Leave it to the List to provide twenty different answers for my "problem". I should clarify my problem a little. First the darkening of the fruit is only appearing on the end of the Scotch Bonnets. The fruits are still firm. None of my other chiles (Charleston, Tabasco, Peter) or peppers (Bells, Jingle) appear to have this discoloration. The chilies are in large containers in a partially enclosed greenhouse (i.e.. derelict-lots of broken glass) in Dublin. Being a transplant from Colorado and Arizona it has been difficult to cope with the lack of El Grande in Ireland but it is getting better. Thanks for the help.
