But...it it is below the graft, it needs to be grafted again.

I just removed 2 dead trunks out of the 5 that came in the pot when i bought it. I was inspecting the plant and noticed bark missing on one of the trunks, so i felt it and it was mushy. I just carefully removed the wire holding the braid and pulled the dead trunks out without disturbing the roots from the other trunks(I hope). I kinda just snapped it off at the bottom. I did it today so we will see how it does in the coming days/weeks. I'm wondering if it was a mistake to just snap the trunk at the bottom and pull out the dead wood pieces?

i doubt it will die as it's not a terribly old tree. Over time the "side leaves" as you call them will begin to compete to become the main leader. In several years you will not know that there was a dead piece to the tree. My only concern is that you were lucky that the tree was relatively small when the wind/lightning took it b/c if it were larger it would have certainly damaged your home. I would remove it just due to the proximity of the tree to your home, and not due to the durability of the tree. Pictures can be deceiving, but if the tree isn't very close to the house, I would just leave it be.

I see one trunk with green stem that might come back. The other trunks look like they are on the verge of death, and probably will not survive. A couple trunks are outright dead. Given the condition of the tree, it is impossible to say if any part will survive. But to give it the best chance, move it outdoors into the bright shade. If there is life, you will see new growth within two weeks. The next step after that, if leaves appear, will be to separate the dead trunks and re-pot the healthy trunk in new mix that is porous and free-draining. Josh
