    As you can see there is a giant bark? clump that the roots are in and then it was stuffed very tightly with sphagnum moss. From what I've read the pot is much too large and the moss is not a good idea.

    But how do I get the bark out without destroying the roots?

    This is my first dendrobium, I have 5 Phals as well. There was a tag in the pot, D. Salaya Candy, but my bloom is much greener than any that came up on Google images. The plant was rescued from a big box store clearance rack.

    Thanks in advance for any help!

    I personally have never seen anything like what tightly encloses your Dendrobium. Maybe someone else here at the Forum has. Your absolutely right about the moss being a bad idea. Dendrobiums like to breath and dry out more quickly than the moss allows. That 'bark' looks so compacted with roots This is probably going to be a hard pain staking job to remove it. Try soaking the root area in water to soften things up first. You might then try to remove the wood carefully with sterile tweezers and and a sterile razor blade. If your literally tearing the roots (a lot of roots) into many pieces, if it were me I would stop and pot up in a smaller pot (leave one inch from the pot rim and roots open). I would use lava rock as the medium or other rock that holds some moisture. After repotting wait at least a week before watering. If most of that wood is still bound up around this Dendrobium, with time, watering, and fertilizing it should eventually soften up and start to degrade and you can remove the stuff then. Use a clear pot and keep a eye out for this purpose. Good Luck and Much Success in this! AL

    It is some sort of coconut chunk. I bought a couple of Cattleya seedlings from France a while ago and they came in the same medium! I repotted them into bark, as that medium was too water retentive for my growing conditions.

    Yes that is coconut husk, this is how orchids are cultivated on a commercial scale in Thailand. The orchids are always potted in coconut husk stuffed with moss even though the medium is very moisture retentive it is not a problem in warm dry Thailand because they are way underpotted in tiny baskets and always hanging in air currents so the media dries out in a couple of hours. By growing this way they have to water twice a day and fertilize almost everyday. That is how they get to grow there plants so big and healthy in such a less amount of time.

    To gt rid of this media gently cut the string or a rubber band that will ave tied all those husk chips together, I can see one in photo#3 . Then soak the plant is water and using tweezers gently remove the moss ball in the centre, that is the problematic bit as it remains too moist for conventional bark potting or the SH media. Once you have remove the moss, you can again wash the roots and leave the coconut husk as it is and plant the entire plant with bark mix, The coconut husk will slowly decompose away and when you will do the next repotting in about 2 years you will find no trace of it whatsoever.

    Yes , I agree with Amey, - that is coconut husk. Almost all the dendrobiums and cattelyas in Thailand are grown in coconut husks and packed tight into plastic pots with slatted sides. I think the sphagnum moss was added later by the last vendor. Amey has given you very good advice re the coconut husk. I normally allow the plants to continue growing in the coconut husk until they have outgrown the pot they came in and then repot the new p/bulbs or canes that have grown out of the pot in charcoal (my preferred medium).

    ...And don't you love that flower?! Such a pretty green with a little bit of blue at the throat - great find at the clearance rack!

    Thanks to Gabi, Amey and Yew for the information about the coconut husks!

    Interesting. Never got an orchid potted in this way. Glad you are repotting that one.

    cheers,

    Just as others have said that Den has been planted in Coconout Husk. I cannot see where you are located, but for us here in the Caribbean, Dens. in that medium spells disaster. When we get orchids shipped in that the first thing we do is to remove ALL of that by soaking and gently pulling the the roots out. You might lose some roots but Dens are pretty tough. We then repot in charcoal & Aliflor.
    If the plant is left in the coco husk it is kept too wet and the roots rot, and the husk degrades in our climate very quickly.
    Good luck. It is a very pretty flower.

    I certainly wouldnt keep it in the sphag either, put it in bark, or a mix of small river pebbles and bark, as they sometimes like to grow on rocks (lithophytes) and dont like the moisture around their roots thats sphag provides
