Hi, I bought a mini calamondin orange tree about two months ago. Lately, I've noticed its leaves are turning brown or simply falling off. All of the fruit has turned yellow and a few of them have dropped. I've been giving the tree a little miracid once a week and watering it 3-4 days. Before doing some research, I transplanted the tree in normal miracle grow soil into a big shallow pot. I'm really not certain as to how much sunlight it is getting since I'm not around in the morning hours. Is it possible I am overwatering the tree? Should I try to transplant it in different soil? Thanks for any suggestions!
