Need help with Ludiscia Discolor

[Paul Mc]

So, I woke up this morning and my blooming Ludiscia Discolor had one stalk that was no longer upright. I investigated it and found that the base had separated from the rest of the plant. I looked at the separation and it was mushy brown.

Now, I've read that you can break them at the nodules and root them. Can I do that to save this portion? I don't expect to save the flowers as there are no roots, but I am unclear what to do to get roots. Do I put it in a thin layer of water like a vine, or just clean it off and put it in the soil?

BTW, I am not so sure that it rotted and then fell over. It was a very thin offshoot from a thicker branch. I was actually just thinking the other day that I should stake the flowers on that particular spike as it looked a little heavy and was leaning. Oops, lol...

Any advice is welcome for rooting and how to clean it. I've never had to deal with this before.
