You need to water them as often or as little as necessary to provide what they expect. Frequency of watering depends on many things, the type of mix you're using, how warm it is, how dry (high or low humidity), how much air circulation you have, etc., etc. It's best to look at what the plants want then figure out how to give that rather than say something like "water once a week".
First the Promenea:
I found this article on Promenea that seems to give competent cultural advice. They like to be a little moist, never waterlogged and never allowed to dry out. You may find that during warmer, drier times of the year you water more often and during cooler times of the year you water less often.
Now the Den.: What species is it? This will help to give you advice on its watering needs.

My understanding is that they can bloom almost any time though I'm not sure about that. Maybe someone who grows a lot of them can give a better answer.

Probably if it is dead, brown and dry, but let me double check when you tell what species it is.
