Coming to dormancy in mid-December
Freshly harvested bulbs
I have grown this plant for many years, there can be a difference in planting but the blooms always appear around first week of June.
I have planted them in ground, pots of all sizes and even in tubs for mass effect. Multiple bulbs in a pot will not bloom at the same time; the overlap is in days and not in weeks.
The bulb has extensive root system, I have seen root at the bottom of 18 inches pot. The bulb develops roots before putting up a scape (in mature bulbs) or leaves (in smaller bulbs). The bulb keeps growing till dormancy early winter. During dormancy you may leave it in soil or lift clean dust fungicide and store at a cool dry place, preferably in a net hanging in shade.
Based on the past experience next year I will be trying new cultivation schedule.
