    Default this medium ok? possible mold...

    hi.
    i'm taking care of this orchid for somebody. i got it a couple days ago and i haven't seen an orchid potted like this before. it seems to be crammed in the middle of a few huge chunks of bark. the shape of the pot has even stretched to fit the bark. the roots have grown out the top. some of the tips look like they are splitting. that is mold that's starting to grow on the bark?

    so far the plant seems to be fine. it has some little green sprout starting to come up. i guess i'm wondering is it ok to keep it potted like this? and if it is mold can it spread to other plants?
    thanks

    That is chunks of coconut husk that box stores receive some dendrobiums in..in my opinion it stays way too wet. I think the round "balls" are a timed release fertilizer, but can't tell for sure in the picture.

    i thought they were fertilizer balls at first but i think they are tiny pebbles. the husk is damp and can easily be broken apart.

    Oh-oh! Do the little gray balls squish when you press them? If the answer is yes, repot this plant in fresh bark, as squishy balls are slime mold.

    Hey, also - those tiny white crystals on the chunks of bark - that appears to be salt that has seeped out of the bark chunks. Many times the coconut husk is washed in ocean water (salt water) and if it is not cleaned well, will release salts onto your orchids' roots. If that is salt - repot right away. It will burn the roots otherwise.

    Cheers,
    BD

    i'm gonna attempt to repot this orchid. i have a question about the roots that are growing up out of the pot. do i trim these or shove them down into the new medium which is going to be a mix of mostly bark? i've never repotted before.

    Nicki, since those roots grew in the air, they are best left in the air. Remember orchids need air to the roots, thats why planting media is porous. I would let the roots growing upward go unpotted.

    thanks for the help. turns those lil gray balls that i thought were pebbles are actually squishy. the plant has been successfully repotted. hopefully it takes fine to that.
