If plant were mine i would slip out of pot inspect roots if severe circling of them i would take very sharp knife and slice from top to bottom just the outer ones not deep into root ball .

In your picture -

Its hard to see the nodes on the new growth if there are none i would take the new growth out and cut down to just above node on last seasons growth.

Plant would then be put into bigger pot as with annual fertilizing this season it will be rootbound by early summer if its not already.

The next dormant season i would take out of pot i would then save that main branch on right side of picture which is in middle of pot take out all others to have 1 main single trunk.

Thats if it was my plant only.

what Martin said

My fig tree did the same thing. I wintered it in a dark closet that I thought wasn't heated. To be honest I forgot all about it for a few months. When I went to check on it there was new growth, white leaves and even a creepy white fig growing on it. I'm not sure if I should let it ride and see what happens or prune it off now before it goes outside.

The whiteness is due to the lack of sun, if it were me I'd cut it back to the older wood, but it didn't hurt to try leaving it, as it warms up outside it should be fine

if you're going to leave it, I reccomend that you pinch off the tips to encourage lateral growth and strengthen the stems

I pruned two of the three as an experiment but I will go back and pinch off the top on the remaining one. Thank you for your input!
