My Hippeastrum collection, mostly hybrids, has grown out of control for the amount of space and Chicago winters that I have.  I force and bloom mine in a greenhouse environment starting in December.  I end up with the same problem of “floppy leaves” that you describe.  My experience is that this is the result of the lack of sun and the leaves stretching toward the available light.  (My greenhouse is attached to my house and faces east so it gets only a half day of sun.)  I have not noticed any difference in leaf behavior whether I plant the bulbs with all but the neck exposed or half the bulb exposed.  

After the last frost of Spring, I remove mine from their pots and plant them out in the garden in full sun (after letting them acclimate to the sun or throwing a piece of shade cloth over them for reduced periods) and the new leaves grow quite strong and don’t fall over.  

Hope this helps.
