    You are right. I think the reason for this advice is simply to avoid
stagant conditions over winter. The temps are lower as well as the light
and this is a great time for diseases to attack. Keeping the soil drier, in
culture, is one surfire way of stopping disease causing organims from
becoming too numerous.

    Are you sure they died? D.cistiflora also appears to die as soon as
they flower, but are only dormant in their tuber like roots... I'm not
saying that it is easy to keep them alive over dormancy, but I have found
live roots in what appears to be a dead pot. Collect the seed though, it is
not an easy plant to keep for several years.
