Andrew,
I typically like to clean up the break on both the branch and the parent plant. Let the parent plant dry out once you have cleaned up the break and then seal with caulk or pruning sealer or liquid electrical tape. I use George's "Citizen Insane" pre rooting method...Once I cleanly cut the broken branch I like to dip it into rooting hormone so along with the sap it creates a "crust" then place in a humidity chamber or cover it with mulch in a box to callus. You can also wrap it with a damp shop rag/towel and leave it alone for a couple of weeks if you are pressed for time or space. Just find a way to let it heal in a high humidity warm location.

By the time its callused you will probably need a heat mat to help it root. So if you dont have one of those you should go ahead and order it or buy locally. After that its just a matter of the bag method or the clear cup method. Either one should work. Good luck and let us know how it turns out.

So, after I cut the branch, dip it in root tone, and wrap it in a rag before putting it in a mixture of perlite and soil?

I have no idea what callus means? I mean I do, but what should I look for?
