My mango is 2yrs old about two feet high and has two or three branches, It has been kept inside except for the summer. It is inside now as temp here is 39F at night and 65-75 during the day. However a few days ago it started to get brown spots and dry leaves from leaf point back to stem and the leaves fall off. Has it out grown the 10" pot or is it too dry in the air or is it an infection. What can I do to save my plant?
