Why do my bonsai trees save dying? ...
Answers: Bonsai trees are incredibly beautiful and one of the trickiest plants to hold on to healthy. If you over/under river them, over prune them or allow them to sit our in a dark chill they will die. Not to mention each type is handle differently. The only true suggestion I can offer is to be in motion to your local greenhouse that sells these plants and reach a deal to them. They will tell you the rough and ready conditions you will need to hold on to them in for their survival. Once you catch it right, they are a wonderful thing to hold around the house.
