I have several tubers in pots outside. The leaves haven’t all died yet and they are huge. I know to dig up the tubers, clean them carefully, dry them and then wrap them in paper. But can I cut off the leaf stems first?

Yes, you can cut the leaves off to store the tubers. Ideally, you would wait until most of the leaves died by themselves before cutting them off. But more importantly, you need to bring in the tubers before it gets really cold, so you can cut still-green leaves off in order to do that. Wear gloves while cutting the leaves, because they contain an irritating sap.
