I have grown these outside in a grobag and they are now about 6" long, but no sign of them turning red, in fact some of them are turning black in places. Any suggestions, please?
My chillis turn an ominous brown/ black - before turning red! Hope your peppers are doing the same...
I've got chilli peppers that go from green through black to red, but I didn't think sweet peppers did...
Growing chilli peppers for the first time, they are slowly turning from green to black (and then hopefully on to red).
