lemon AND leaves turning yellow...
The surviving one of two Meyer lemons that started out last April began to get yellow on one side just as our nights started to get really cold. And at the same time I noticed that the leaves were also getting yellow. They have been healthy glossy green since I brought it home last December.
I have brought it in the house, and the leaves have started to drop. The lemon continues to get a little yellower each day, and smells like a lemon!
It occurs to me that no leaf is eternal, but is it typical for them all to yellow at the same time? Will the plant defoliate? Should I feed it some nitrogen?
