My 20 year old plumeria was badly damaged last fall. Had to store it outside. (Normally kept indoors over the winter) Tried to save it by covering with plastic and putting Christmas lights inside plastic to keep it warm. It burned the trunk. This summer the outer bark peeled off. You can see in the photo these small roots? growing. Also the bottom is growing like crazy. Can I cut the trunk at the damage site and replant it? Thanks so much! I love the tree.
