Hello! I recently got my first bonsai tree from the store Lowes. Has anyone ever seen their bonsai? If so, you notice they are mallsai. I got a Chinese Elm from there as an early Christmas present. I am asking a question about all the leaves on the tree. They have all fallen off. It was not in correct soil. I put it in deciduous bonsai soil. When my mom gave it to me she said she got it in the indoor part of Lowes. I am also asking if this tree should be outside for the winter. Should it? I have it indoors next to a window. I need some advice please!! THANKS!
