While these are often called Fall crocus, they are actually NOT crocus , but members of the Lily family.

I planted three originally, they started to increase but I moved them to a better location when I replanted the bed they were in which was under a south facing wall, where I felt they weren't doing the best. The bed I moved them too became too crowded with other shrubs blocking out too much light and maybe taking too much water, they were growing leaves in spring but stopped flowering. I moved some once more, this time I had even more bulbs as they split making several bulbs. Moving is best done 'in the green', that is when they start to grow leaves in spring as they make flowers only in the autumn.
The bed I put them in is on a slight slope, they are planted around the bottom end of the slope where they keep moist but also get some sun as well as shade. This seems to suit them! I have sandy, free draining soil, the bed had been mulched well with home made compost consisting of mainly leaves. I have never fed them and they continue to do well, they have proved to be very hardy in the UK but should be planted deep. Leaves die back for the summer.

The leaves for colchicum come up in the spring and die back some time around June. Colchicum are marginally hardy here (zone 3a) so I mulch the plant in fall after the blooms have faded, if snow doesn't cover it first.
