My plumeria is extremely healthy but come to find out it now has a hole on its main trunk.
Is this rot or too much nitrogen and organics causing it to just grow too fast? Should I treat it to try and stop the infection or better off chopping it and re-rooting? Thanks 🙏

Don't mind the tie backs, I'm slowly but surely correcting its angle to prevent it from becoming so top heavy. Could the gradual tightening be causing it? Every couple of weeks or so I untie it and tighten it slightly

I have observed some stem injuries that are undiagnosed in which the stems develop some dry, non-borer insect like, spots that eventually become holes and snap off. Only one side of the stem is affected and water does continue flowing upwards. Not sure if it is a winter injury, root rot or what. In the cases I have seen, the affected areas can be cut off so you end with a new cutting and a stem that will soon continue developing as well.

It should just branch back out along the nodes, right? Do you suggest I wait till fall right before it goes dormant?

You can cut above and below the hole now if you wish but if it is not growing larger, I would wait until it goes dormant and then cut.

with Luis, if the brown part where the hole is not spreading (meaning not a rot) I would wait since you might not have enough growing season for the roots to develop.

Not sure how tall your plumeria is but you will to cut above and below damaged part. A mature cutting can be Stored in a warm dry place until spring.
