Our potted bulb/corms(?) begonias are dying off now but still not quite dead. We want the pots they are in for primroses but are not sure if we can just pull up the begonias and dry them off for winter or if they should be left where they are.

Dry sand or even dry compost will do if you haven't got sawdust.

lift them out and leave them to dry off. then brush off the compost and keep them in paper /sawdust somewhere frost free and cool until next spring.
