I'm honestly thinking this won't make a good bonsai because of the dead side, which is why I want to get my hands dirty now (but I am a newbie). I'm thinking of just removing the extra shoots from each place, so that there is only one "branch", therefore thickening up quicker.
I wouldn't mind loosing the whole tree from it being strangled, to be honest. I really like the look of interlocked roots on strangled trees, and I do love figs. I have some other privet that I'm watching recover and want to start some work in summer, depending on how much growth they get this winter and how they handle spring
On a general note, two years seems crazy to me for free growth. To me, even a year would result in a HUGE shrub/tree. Surely some basic branch selection and mild pruning would begin before this? Even some wiring before the branches get too thick would seem like a good idea. Or am I thinking about this incorrectly? This was collected not even one and a half months ago, so I can't imagine the growth after two years.
I know I'm pushing recovery and growth times here, but I have many other "waiting" projects going on, and I'd rather try something and fail or kill this plant than just watch it for awhile. Kind of want to improve my wiring skills and try other techniques (e.g. grafting etc.), and this guy seems like a good plant to experiment on.
