Bonjour
the dormancy period in MEXICO corresponds to a dry spell, that's why, as the plants are succulent leaves,to protect and still succeed to live
the wet period in Mexico is between June and October
for me, begins a dormant period, and during the wet period that ends gives them insects (if they are outside they are in charge of themselves), or default, glitter for aquarium fish, but not too much or they will make a indisgestion.
if you respect the cycle I think they will bloom
