What to do after the bloom

[bouch113]

Hello,

My name is Alaina, I'm new to Orchids & this board. I have a Hard Cane Dendrobium & a Miltassia = Miltonia x Brassia, from what I'm told lol. They are both at the end of their bloom; the Miltassia's flowers are starting to wilt & the stem is turning yellow & the dendrobium's flowers are dropping (1 left barely hanging on) but the stem is still green. My question is, do I cut the stems back, leave them alone, not sure what to do from here? Will they bloom again this year or just once a year.

Thanks in advance,
Alaina.. Daytona Beach, FL
