    Default Yellowing leaves on phal orchid

    Hi,
    I'm fairly new to orchids and have had mixed results with the ones I have purchased so far, and am COMPLETELY confused . I've had one Phal for 3 years and it is FINALLY about to bloom, I only repotted it twice, once imediately after buying and initial blooms fell and about a year and a half ago. I then purchased a Vanda and a Dendrobium from the orchid show in Ottawa, both died Vanda was shocked with too much light and went downhill and I believe the dendrobium stood in water with the ceramic glazed pot I had put it in ( the half I seperated and gave to my mother is still alive however.) I now bought an "everblooming" Phal waited til blooms fell and repotted since it was in a plastic pot with nothing but sphagnum. I cut many dead/black rotting roots, it still had a good number of live ones, it stands at the same window as my 3 year old phal so I don't beleive it's shock from the light and since transplanting 4 leaves have yellowed and have either fallen off or about too and it doesn't look NEARLY as healthy as the other one. I don't want to loose another one HELP!!! Pictures will follow as soon as possible.

    Thank you!

    Stefanie, Welcome. It is common over time that a bottom leaf will turn yellow. How often do you water this plant? It looks like the bottom three leaves are a little wrinkled in the second photo. This plant might want a little more water. Good Luck,Rich

    Being in a glazed pot doesn't allow for air exchange with the roots easily. You may have root rot damage and that could cause your leaves to turn yellow. A sign of this is the wrinkled leaves that Rich points out in his post. It might be a good idea to repot and clean up the roots on this phal.

    cheers,

    Hi,

    Would it still be advisable to repot and clean up the roots if I just did that about 2 weeks ago? What are the signs of root rot and what can I do to stop it, should I transfer it to a terracotta pot? It's watered when I feel the first 1.5 inches of the medium are dry so every week week and a half.

    Thanks for the advice,
    Stefanie

    Hi Stefanie,

    If you recently repotted, and the damage has happened since repotting, then the orchid is staying too wet and/ or the roots do not get enough oxygen. I would put it in a plastic pot or terracotta pot (unglazed). Also, what is it now potted in? Is that sphag and coconut husk? It might be simply potted too tightly and retaining to much water. Is there some styro in the mix to hold the medium apart? Some charcoal? Anything?

    So sorry you are having trouble. Hopefully we can find the cause and you can help this phal recover.

    Cheers,
    BD

    It is strctly coconut husk and sphgnum as the other phal I have seemed to like it. The medium is so loose the plant moves.

    Should I treat the roots with something before I repot it and what mix should I use as well? I'd like to give the plant a break after this time

    Thanks!

    Then you should probably pull it out and take a look at the roots. It would be a good idea to put it in a pot that can breath too. I would also add in some styro peanuts to the bottom of the pot and some perlite and hard bark to give the orchid air and something to attach itself too inside the pot. It is very easy to over water sphag and coconut husk.

    One other thought: Did you wash the coconut husk well before potting the orchid in it? Sometimes, the coconut husk we get here in the states is washed in sea water instead of pure water and it retains salt. This salt can kill the roots of your orchid. I am sure you washed the coconut husk, but it is something to consider if you did not.

    If you take it out. Do let us know how the roots are doing. Good luck to you.

    Cheers,
    BD

    Thanks for the advice! I'll definitely post back when I repot.
