I agree strongly with what Kipp said. In nature, the tiny bulbs would be
growing in the ground, and would have roots reaching down to levels of the
soil that would still be moist and cool at this time in a normal year.

I've killed plenty of Calochortus over the year, so I can't say this for
sure, but I get the impression that they don't rot if you keep watering them
while they still show some green. When they're ready to be dormant, I think
the whole leaf will tend to go yellow at once.
Hope that helps.
