It might take a couple of years of potting on and feeding before your bulbs get to flowering size, Bilje. My friend in australia had one growing outside, and it looked congested, so I dug it up. 34 bulbs later, we filled an area a metre square and gave them a good feed. it took two years for them to flower. I believe from seed to flowering size bulb takes 3 to 4 years.
I think if you are careful with the roots, you can split it and pot each one on individually at any time.
