Hi, I normally have my Madagascar Dragon Tree outside. I live in Louisiana and it does not get too cold down here. I went out of town for two nights and the weather dropped from 79 degrees to 32 degrees without notice (thats normal for down here). When I got home my tree's leaves had completely dropped to its sides. I have kept it inside for the last two weeks, and plan to keep it in from now on, but it does not look any better than the day I got home. Is there anything I can do, or is my poor tree dead? Thanks!
