I'd like help determining whether this firethorn is able to be saved. Please see photo.
I had a baby six weeks ago and I probably was too careless with the care of this. I'm also a newbie so I'm very uninformed about bonsai care overall. I acquired my 2 bonsais during the fall last year and have yet to prune (except for removing dead leaves) or add fertilizer.
IF salvageable, I'd love help figuring out next steps. I stopped watering it so frequently when I saw the leaves turning brown. I've tried changing the amount of sun exposure, and I'm not sure if that's working. My next step I believe is to remove all the dead leaves. I've read I should use a water soluble fertilizer but I have no idea where to begin in selecting one, and how to use it. I also have never misted the leaves, should I be doing that?
