Glad you discovered rot on the thick succulent roots and have excised them. Good that you've hung up Clara before planting to allow the cut areas to heal/callous over. It will take about a week to callous. To clarify for readers, if there were no rotted succulent roots and had trimmed only "fine" roots, then it is okay to re-plant right away.
About overdoing by treating cuts with both rooting hormone and cinnamon...I say yep!
But I don't blame you for being cautious. As for myself, I don't treat root cuts, I just allow them to callous over.
Kate, maybe you could find planter bowls at yard/garage sales. Or maybe at the flea market. If I'm not mistaken, there's a Saturday flea market in Pearl City.
