Catasetum-confused-need advice

[Sandy4453]

Since there have been a few questions recently that have popped up regarding Catasetums and since they're ending winter rest, I've got a couple of questions, if someone (Steve ) can give me a little guidance.

I failed completely with mine last year, had no clue what to do and still, don't recognize when things are going fine or not or what may need adjusting with these.

I'm down to 2. The first one was taken out of all medium and rested in a net pot, bare rooted, all winter. It's been putting out this growth for the last month, the longest root is about 1/2", there are 4 new roots all together.

I left the other one in the pot with medium in tact. I stopped watering the same time as the other one but so far, no new growth. Yesterday, it poured all day and the one in medium, is still wet...a day later. Since I've read everywhere that no water until new growth with roots at least 2", should I take the plant out of the medium and let dry? Is it probably doomed now for the garbage bin?

I plan to pot these up in sphagnum with some tree fern to keep the mix open. Should I wait till the roots grow longer on the one putting out new growth?

In another thread going on now about these, mounting was brought up. When would it be appropriate to consider mounting over potting?

Anyway, thanks in advance for the help I direly need with these.
