With all due respect, that's not the course of action here....and there is more than just a little history of arbor culture care on the island. Wounds, large pruning cuts, cracks, etc, get covered with a relatively thin gooey substance, similar in viscosity to white glue. Not sure what all is in it, but it contains an anti-bacterial agent. Any gardner will have a tub of the treatment in his truck.
The photo reminds that Jerry's book gives some good reading and photos regarding gaff wounds in trees....changes over time.
