    Default ATTENTION: Help! What's Wrong With My Phalaenopsis?!

    Hi everyone,

    this is my first orchid and I received it as a gift approximately 4 weeks ago. Today I re-potted the orchid in a new medium (the first medium was sphag; the new medium is bark) and noticed that about 70% of my roots were rotten, which I removed with sterile scissors. First of all, I really want to know how the root system is looking and whether or not my orchid will survive? Is there anything that I can do to promote root growth?

    Also, there are brown/black areas on the green roots and I didn't know if that could be an indication of root rot and whether or not I should take action and cut it off, which could then potentially leave me with no green roots. What should I do? Would it pose any problems to my orchid?

    In the third picture, there is a black area on the bottom of the plant as a result of the rotten roots that I cut off. Should disinfect it? How? Should I completely remove the area?

    Another thing that I want to bring to attention is that I noticed a blackened area at the base of the right leaf. There are also brown/black spots on the leaf above the blackened area. Can anyone help identify the problem and provide details of what I should do to remove and prevent it from happening again? I was thinking of cutting off the entire leaf right down to the roots. But the thing is, I'm afraid that I might remove a portion of the roots, since the black area is so near it.

    Finally, the underside of the top leaf is turning into a maroon colour. What is the problem?


    Thank you so much for your help!

    I am not an expert on phals, but I had one given to me in August in spag, and by the time I repotted it, it had fewer green roots that yours does. It also had reddish leaves. I trimmed as much black as I could without killing more good root, sprayed the whole thing with antfungal stuff, let it dry a few hours. and repotted it. It recovered well in bark, and now has great roots and is in spike. Still has reddish leaves.

    So, while I can't say if what I did is the "proper" way to handle it or not, it worked well for me. I do think you have enough root to hope for recovery. Good luck!

    Kathi's advice is good. The reddish leaves can be genetic or the plant may be getting too much light. The reason depends on the conditions the plant is growing in. When too much light is involved, the reddish color is like our skin when it tans-the reddish color helps screen out the excess UV. Some Phals depending on their genetic background have reddish leaves and that is normal for them.

    Are the reddish leaves a potential threat to the plant in any way? Also, I checked on my plant this morning and notice that the reddish colour has spread to other leaves; initially it started off on only one leaf.

    Hi Kathi,

    I'm going to attempt to trim off all the black rot. With regards to the antifungal spray, could we possibly use cinnamon as an alternative?

    With regards to the black rot ON the root, do you suggest that I cut out just the black or should I trim the root with the black on it?

    Hi npang, your plant doesn't look all that bad and I would not worry too much if you follow Kathi's advise. keeping the plant on the dry side for a couple of weeks after re-potting will improve the regeneration of roots and prevent further root rot. With regards to the 'reddish underside' of the leaves, from my experience of phalaenopsis growing, a reddish color often indicates that the plant is receiving the optimum amount of light and should be regarded as such as a good sign. I don't have documentation readily available with regards to this aspect but will post some if I could find any.

    I wouldn't worry about the color..it looks fine. As for cinnamon, I have used it on leaf cuts, pbulb cuts, but not on roots...I've been told it can dry them out too much. So, not sure about that one...maybe someone else has tried it on roots. I would trim the black spots off where you can, and not worry too much about the rest.

    I don't worry about it unless the plant actually shows signs of burn-yours looks fine at this point.
