Hello all, I purchased a bonsai about 4 months ago as well did my brother. I don't know the type but I keep it indoors and I have been faithful and taken the best care of it to the best of my abilities, my problem is that I don't know much about these beautiful trees and I may be doing more harm than good. It has been steadially loosing all of it's needles and turning really brown. I did repot the tree and put it into miracle grow soil. It seemed to get somewhat greener after a couple days. But now it's looking really pathetic. I don't water it directly, I have a spray bottle that I mist it with several times a day. It just donsn't seem to retain any water. My brother is doing the same process to his tree and it is in much better shape than mine. Any help would be appreciated.
