I don't know the name of this gorgeous red Epi or anything of its parentage, so please take this with a grain of salt :
Red Hybrids which have Disocactus ackermannii in their parentage benefit from a cooler dormancy during the Winter. Not lower than 40 -45 deg F. Years ago in Germany growers would place them over the Winter into their stone cellars and bring them back upstairs/outside in the Spring. I place mine into our frost-free garage in the Fall. They do bloom better this way than kept in the house over the Winter at room temperature.
Just a thought!
