Maybe I'm way off base here, and I expect the more experienced members to correct me if I'm wrong, but why not just wrap some sphagnum around the stem covering those root nodes? If they produce roots you can then cut and pot it up.
Well, I made some better pictures to make sure you guys understand I'm not torturing my plants
As mentioned, doesnt look unhappy. I was just worried bc I have had some spider mites and some brown scale on some different once that this here is not related. If someone now could advise me on what to do in terms of propagating, that would be awesome.
