    Default Cattleya pot medium

    Hi! I bought this Cattleya orchid this weekend at a plant nursery but the seller didn't told me which type of orchid it is (color, specie), he just told me it was the same as the national flower of my country. So, this orchid should be a Cattleya mossiae. They had a lot (and trust me when I say a lot) of this orchids in the same way I bought this one: clay pots and this medium which I don't know how to describe except as ¿soil?. I don't know if I should repot this plant into another medium or even mount it. However, the plant looks nice and I can see it have bloomed from all the previous pseudobulbs (which also looks nice) and I don't see any dehydrated leaves. It have two growths with a sheath and it's sending a new growth.

    Here is a good link to IOSPE .

    Time to dig down and see if it is a dirt/soil or just a deteriorating bark mix. IOPSE describes it as a epiphyte, so I don't think dirt/soil would be good for it long term.

    The plant looks about right for C. mossiae, but many other large Catt species and hybrids would be impossible to distinguish. I doubt the potting mix is really soil, possibly broken down bark mix, possible some cheap abundant local material, hard to say. It does seem too fine textured for long term culture of this plant. If it was mine I would try pulling it out of the pot carefully to see the health of the roots and better assess the mix, but I would probably wait until there is new root growth to repot in whatever mix I wanted to use long term.

    Concur with Kirk, potting medium looks like mix of husk and some other local medium. Would repot it when it is growing a new roots

    Digging a little bit, some roots looks bad but also I can see some roots growing right now. I'll see if I can find some fresh bark mix and charcoal to repot it. Do you think the repot will affect blooming the next year?

    Make sure that there are actively growing new roots. My experience is that if they aren't actively growing (Especially in the dry air of Colorado) they are likely to fail and die if repotted at that wrong time.

    Active root growth is exhibited by nice green root tips at the end of the root (color depending on the orchid type, I have some with red tips).

    IMO, it may actually help trigger a bloom cycle if it is repotted at the right time (active root growth).

    That looks like a nice, mature plant, but that looks like a tough potting medium to get the watering correct.

    If you are successful with other orchids, I'd suggest you use something similar to that.

    My other orchids are mounted, and a couple of them in clay pellets. I think I'll wait after it blooms to repot it into new media.
