I've had my Bonsai for over 10 years. Unfortunately, it was recently "cared" for by someone else and is now dying. I've been told that it was dropped from about a 3 foot height. Then, it was left lying there for a couple of days. No water or misting was applied for over a week. I fed and watered it but not to excess. It did get a few new green buds but the branches have since fell off. Is this a lost cause or can I try to save it in some other way? Thank you. Any help will be greatly appriciated.
