Dire disappearing Dierama

I've found that Dierama corms in pots rot easily during the Winter if the
soil remains too moist.  For me, they like it neither too moist, nor overly
dry.  In the greenhouse I try to keep them on the dry side, and water from
the bottom only, if I think they're going to desiccate.  The ones outside
in the ground (well draining) fare better, but eventually succumb to the
less than ideal conditions for Dierama here.

I've also lost many geophytes, both in the minimally heated greenhouse and
outdoors, to predation by mice, voles, and the occasional chipmunk,
resulting in words vocalized by me that I can't repeat here.  Sometimes the
soil in the pot looks barely disturbed.  I keep traps set both inside and
out 100% of the time, which judging from the numbers caught has helped
reduce loss, but certainly not eliminated it.

It is always disheartening to lose our treasures, no matter the reason.
