Hi,

This is so heart-breaking to look at a tree that you've grown for years!

Did some pesty insect get into the trunk of the tree?

Look up "three lined fig tree borer" and see if that is it.

Good luck.

Thanks for the tip. That could be it. I'll cut off the dead wood tomorrow and see if I can find one.

It's fig borers. I cut off dead areas and found the caterpillars. I aggressively pruned it out so maybe I can put off their demise.
