Hello I am new to bonsai trees and this is my first. I have had it for a couple months but the leaves slowly all fell of and dried out. I don’t know what I have done wrong and if there is anyway to save my tree. The pictures below are how it looked like when I first got it and now. You can see that now there is a small green sprout in the moss but I am not sure if that has anything to do with the tree. I have seen those sprouts since I first got the tree. Someone please help me I don’t know if my tree is already dead or if it has a chance to live longer.
