Curry leaves (murraya koenigii) turning black
I have a good curry plant where the leaves suddenly started turning black yesterday evening (Oct 6th). I believe it is probably because of the drop in temperature since it has started getting cold. This is a potted plant and I have moved it indoors the previous two winters. Please see the attached picture.
Do you have any suggestion on how to address the leaves that have started becoming black?
Looking forward to your suggestions.
