That is the question. brief history of this tree
bought about 2 years ago and kept indoors until I noticed some of the growth falling off. I then read that it needed to be outside & needed to through a dormant period. It was moved outside during the summer and new growth started to appear from where it had previously beeen was very happy. well the first week it got cool/cold it turned brown, not gradually either just boom 48-72 hours all brown. I'm in louisiana so I figured it would've already come out of its dormancy, been rather warm for a while. I'm gonna attempt to attach some pics, let me know what you think.
Appreciate the help
