i have a 4 yr old cherry tree. it has been doing great until this spring. it started to bud a month ago, but then never finished and never flowered. it looks dead. when u pull the bark apart it is moist and green inside. it does sit in an area where it is prone to a lot of water for a lenght of time. is the tree dead ??or because it is moist and the bark is green inside...will it eventually come back. or should i pull it out?
