Dendrobium question

[Jayb]

I was given a Spring Dream Apollon for Christmas last year, very pretty and it flowered beautifully for it seemed ages. It's growing well and I have around 5 or so new shoots, which are about half the height of the last flowering ones So do I cut the previously flowering stems back or leave them? They still have some leaves on them if this makes a difference.
