I know these are terrible and die and split. But--my mother in law has one and I think it is dying. Tree is higher than a one story house. The vegetation and top looks healthy. On the trunk the bark is falling off in large sections. The wood inside has a white powder sheen on it. It is clear to me something is bad wrong. Live in a small town that has no tree surgeons other than someone with a saw. Anyone have any thoughts

other than a chainsaw?
