phal. cornu-cervi var. chattaladae out of bloom

[Kevinator]

Hey guys, Kevin here. My red phal cornu-cervi bloomed for around three months and now, all three flower spikes are bare and no new flowers can be seen. Is this normal? I know that the species can throw up multiple flowers from an inflorescence for an extended period of time, but the bare stems aren't dying. Should I cut them or leave them there? Also, what is the preferred potting mix for these guys? When I bought it, it came in pretty bad-quality sphagnum.
