To cut or not to cut: Ansellia africana canes rotting
 

I hope you guys can help me save my gorgeous Ansellia africana. I was away for 6 weeks and bf was left with the orchid watering. He stuck to the once-a-week watering and didn't notice that the Ansellia africana had started rotting. When I got back a new growth of about 5 cm was totally brown and soft (I removed it). The 2nd new growth was green but now is also brown at the base and turning yellow. A few of the older canes are also going soft and dark :( What should I do? Should I cut the soft canes? It's not specifically any row of canes that are soft so I can't just cut a section. I would have to totally separate all the canes into individuals (which I imagine would weaken it quite a bit).

Odd thing is that the roots don't look too bad. They're a bit worse than when I left but there are definitely lots of functional roots in there. I haven't watered it once in the week that I've been back and the bottom of the medium is still humid :( It was repotted about 7 weeks ago and I kept it in rock medium.

I would remove them if not a group of canes that you can remove in a division .
I would dry it out un pot it and remove any soft roots . Be sure to use a sterile razor blade for each cut then throw it out as the rot can be spread to non infected plant parts and to others in your collection, isolating and gloves is a good idea . After you make the cut can pack cinnamon on the cut then a coat of an antibacterial salve to seal it ..Sorry about the trouble that is a nice plant ..

I would completely the bad ones. Also check the rhizome for any signs of infection.
