Almost all the resources that bulbs need to flower come from the bulb itself, not from the soil. The only essential thing they need from the ground is water.
If you can lift a reasonable size block of soil around the bulbs, big enough not to break any roots, they won't even know you have moved them. Make sure they don't get too dry and they will flower normally.
The most important time is after flowering. If they are in pots, give them plenty of liquid feed and water until the foliage starts to die back. Stop watering and feeding and leave them to wither naturally. Then lift the bulbs, store them somewhere cool dry and well ventilated, and replant them at the same time as you would plant new bulbs.
