Don't rightly know what the hell it was sick with, Jason. Perhaps it was frost damage from last winter, perhaps it was age.
You ever have a fig bush where some of the canes just die off and new ones come up?
The splintering of the trunk sure didn't affect the distal growth as it was putting out all those air layered roots, healthy leaves and figs. Don't know.
BTW, figured out why the root ball was predominantly on the underside. Duh!
