How we know it's a he?
K...next suggestion, given the emerging roots do not look happy...possibly owing to the base rot creeping up:
what I would do, given all you share and the odds of him or her coming back as he or she is....is to remove the lower leaves, it doesn't need many to come back as long as the crown is OK.... thus exposing nodes for new roots! Again, cut back the bad part of the base to new, verdant, healthy tissue....dust it, let it form some callus.
Then, I would pot it up in tiny clay pot with NZ moss and the two wooden stakes stabilizing it as I described....then, drench it with a fungicide solution and let the medium it dry before you drench it again whenever. That is what I would do....and have done in a coupla cases with some really sick ones which come my way I thought were beyond saving. Are some actually beyond saving? sure.
But, I only give up when I see I have to.....and just trying....bears infinite, precious lessons!
