If your plants continue to grow, and you aren't losing the leaves to patches
of black rot, then the best advice is to "keep doing what you're doing," as
you're obviously giving them what they need.

The question "is sphagnum the correct medium" - by itself - really cannot be
answered for two reasons: the plants use the medium for mechanical support
and moisture/nutrition holding only, and it depends a lot on your growing
conditions and watering habits. Going back to the theme of the first
paragraph - it appears to be working for you right now, I'd just keep an eye
on it for getting overly compacted.

What do they need to bloom? More of what you're doing and maturity. Gramms
tend to be pretty big plants, and even the smaller clones of G speciosum v.
citrinum can get to 18"-24" tall (or more) before blooming.

Last fall a friend of mine who grows only Cattaleyas gave me 3 of these
and when I asked how to grow them he shrugged saying beats me they where
given to me. Yeah, he knows I can't say no to a free orchid plant. All
three are planted in sphagnum. I've Googled all over the place and found
only one sight that claims to have a culture sheet but you have to be a
paid subscriber to get it. Right, pay for something sight unseen, NOT in
this lifetime.
What I did find indicates they are warm growing so I stuck them in with
the
rest of my orchids and kind of forgot about them. While doing some
repotting last month I found them with new growths looking happy but I
still don't know if I'm giving them what they need.

I figured I'd find someone at the annual orchid society auction that knew
how to grow them. Would you believe no one there grows these. The best
guess answer I got was I think you care for them the same as cymbiduims.

I must have a couple of things right because they are growing. But what
do
I need to know to make them bloom, is sphagnum the right potting mix, how
often and what do you feed them with.
