I have a fukien tea tree that i purchased at a bonsai show at the chicago botanic gardens this past summer. it did GREAT during that season. But now it's about 50-60 degrees outside. so i keep it inside. I water it regularly (not too much of course), but i keep it in my bathroom so when people shower, the humidity helps it out. but what i noticed is that the leaves are falling. is it dying?? last year my bonsai died during winter. (my mom kept it on the floor next to a window where all the cool air can come in ..

)
i don't want to make the same mistake again this winter.. can someone please advise me on how to take care of my bonsai? i live in chicago and mother nature gets moody here. please help!! please tell me that my bonsai isn't dying..is there a reason why the leaves are falling? is it because of the temperature? thank you!
