That's just gunna rot!
I root them by taking a cutting that's about as big around as a pencil, cut it back to one or 2 nodes.
Find a shady spot with relatively loose soil, push the cutting a few inches into the soil, then cover that with an upended mason jar.
In a month or 2 it'll start growing, it has roots at that point, remove the jar and water it weekly for the first few months.
It's the most fail safe method I've used!
