Phaius potting advice ?

[EdinAZ]

I wonder if my Phaius tankerville would do well in a large cymbidium pot? I have some of those nice ones from Tindara that are about 7-8" square and maybe 15-16" deep.

Mine was outdoors for a few years, and grew BIG planted directly in the ground, but ultimately just couldn't take the Arizona heat and humidity (almost total lack of) so I brought it into the greenhouse. It's doing fine there, but doesn't grow or bloom quite as "heartily" as it did the first couple of years it was planted in the ground. If it wants more root space, the cymbidium pot should provide that. It's planted in pure garden soil and fertilized heavily while growing/looming. I lay off a bit after it's bloomed.

I'm interested in any experience with this or opinions.

Then . . . what about Calanthe's in those deep pots?

Thanks all.
