Girdled main stem

[FarmerJake]

Had a full stem break sometime last week, staked her, taped her and all seemed fine. Swelling above the tape made me curious so I removed the tape and the outer green layer under the tape is rotting(sucks to think without the tape I’d be in a better position). Tapes been removed and I allowed the rotten part to dry so I assume the woody center is sufficient to transport water to the plant. But I think the out layer is how nutrients are transported and I can see deficiency starting. So far I have thought perhaps a foliar spray would help? Never done one. I also am considering caking rooting hormone on and above the rotten stem then burying it in potting mix in a sleeve. Not much to lose I don’t think but want the collective assessment of AFN because someone will know WTF to do. Would it shoot roots, do I need to make an incision in healthy flesh above the damage before applying the rooting hormone? Any recommendations welcome

Total carnage

I would make a splint for it. I helped my buddy splint a plant with a very similar break a few years back. We used three wood skewers and some zipties.

Movement is no longer the issue, the plants ability to uptake nutrients is what I’m most concerned about

Plants are resilient, it should recover, but most of it's energy will go towards repairing the break so don't expect much growth for a bit.

Feeling desperate I applied rooting hormone and buried it. I opted to make a few select 45 degree upward slices with powder on the knife above the damage to try and trigger rooting. Never done anything like this so it may just be dumb and may be like the tape and make matters worse but no stress on me either way so I’m trying flies were landing on the exposed dead layer
