It’s great how these bulbs become dormant after flowering, eventually the old leaves die down… Then they spring back into life when you water them about this time of year. Little and often is my way of doing it. Water but don’t drench. The bulbs swell, then suddenly a couple of leaves sprout, growing rapidly with a flower spike. I have kept one bulb for ten years. Each time it grows bigger. But don’t be eager to put it in a larger pot. It takes a few years, it likes being crammed in a pot. I only move them into the next size up pot. My oldest has grown a secondary bulb that also flowers….
