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.
