    Default Help - Diagnosing Light Brown "Dented" Leaves and White Spot on Phal

    Hey there! I'm a first time orchid owner so I'm absolutely lost when it comes to orchid care. I picked up a miniature phal while I was at ---- Vendor information removed - see FAQs on Posting ----. The orchid has been sitting in my office cubicle for the past 3 days. I know it's not under the best lighting conditions, but I had read online that some people have had success raising phals in a lower-light office setting.

    I'm not sure if I hadn't observed my phal closely enough when I first got it, or if it's a recent development... But I started noticing some light brown dents on 2 out of the 7 leaves on the plant. After extensive research on the web, I couldn't really decide if it was due to mesophyll cell collapse from being exposed to the cold, or some type of pest infestation...

    There also seems to be a white spot on the edge of only one leaf. The spot doesn't seem to have grown any larger over the past few days... Not sure if that's anything to be worried about either.

    The root system of the plant seems to be doing okay... the roots are either green and plump or have that slight silvery-sheen to it. The flowers also seem to be doing okay. It's just the leaves that are the issue, it seems.

    I've attached a couple of photos of my phal's leaves. I would really appreciate some help diagnosing/treating these issues! Thanks so much!

    Overall Phal looks healthy to me. the first image looks like a edema. may be did you water the plant in the evening when it is cold?. Only observation appears to be that the Phal is grown in full moss. did you get it in full moss?. keep a close watch on the roots as they could rot if it remains wet always. BTW, do you grow them in a small aquarium bowl?

    The white spot on the top of the leaf is just damage of some sort, no worries there. I'm not so sure about the other two leaves, perhaps someone has seen that before and knows what's going on. It could be cold damage.

    I'd be concerned about what it is potted in. Did you repot it after bringing it home? Have you looked to see if, under all the other stuff, the plant is actually jammed into packed tight sphagnum moss inside the display container? They are often sold that way and it will kill them pretty quickly if so. What works in the greenhouse it was grown in usually doesn't work in the average home. Also, does the display glass bowl have good drainage? Orchids exchange air through their roots, not so much with their leaves. It's good that your roots look good now, but keeping them that way is pretty important.

    I concur with Carol and KsiramKumar.

    I would also suggest change the fishbowl with good drainage for better air circulation for the roots.
    if i really want Glass Or ceramic make sure it has many side holes.

    Thanks for all the informative and quick responses! I'm glad there's nothing urgent to worry about. Now I can stop staring at and worrying about my phal while I'm at work.

    The phal actually came in a plastic container packed ridiculously tight with moss. My mom told me that one of her friends had some success planting her orchids in glass, so I let her repot the phal for me. She used the fishbowl, added a layer of rocks to the bottom (for drainage, she said), and then used an orchid potting mix with some sphagnum moss added in as well. Is this okay for the phal or should I repot into an actual pot with drainage holes? And is it ok to repot the phal after it was already repotted once?

    I'll include an image of the bowl so you guys can take a closer look at how it's potted and what's going on. Thanks!

    Thanks for all the quick and informative replies! I'm so glad that there's nothing terribly wrong with my phal. I spent all day at work yesterday staring/worrying/obsessively-researching about all the types of pests and diseases my phal could possibly have, haha.

    My mom actually repotted the phal for me after I brought it home from the store. When I bought it from the store, it was packaged in a tight clear plastic container that was jam-packed with so much moss that the entire container was more or less a solid mass.

    My mom said that one of her friends pots her orchids in glass fishbowls/vases so I let her repot it for me. She put a layer of rocks down (for drainage, she said), and then used a mix of orchid potting mix (mostly bark, I think) and added some sphagnum moss to retain moisture since it's been pretty dry in this area lately?

    Do you guys think I should repot my phal into something with more drainage holes? And if so, is it ok to repot the phal after it's already been repotted within the past week?

    I agree with Jervis.

    Get it into a pot that allow air to the roots. Solid glass will cause the roots to rot!

    It's better not to be constantly re-potting them, but that set up will cause it more harm than potting it properly. The more you disturb it, the more harm you do to the roots, so be sure you know what you want to do, then do it and try not to have to keep changing it again. It's a balance regarding what's best for the plant. The bottom line is that it needs both moisture and air to the roots. Phals also like it on the warm side, they sulk if the roots are chilled (or so I'm told).

    I'm really glad you knew to get it out of the packed sphagnum that most nurseries use - it works with greenhouse culture, but not well at home at all. Although re-potting it out of that stuff is stressful and the change of media will damage the roots, it doesn't damage them as much as leaving the plant in that.

    Good luck!

    Alot of your questions are hard to answer since there is no info provided as to ur culture and climate. Some places do well with moss some dont. Some do well in clay some dont. Depends on where ur from.

    Potting questions would be a guess without location however to answer your first question it looks like cell collapse that can occur when an orchid is kept to cold to long and when water is too cold when watering. Just a warning they may brown and get a burnt look appearance. Symptoms usually occur over a month after the cause so it is sometimes hard to attribute it to cold. Late fall to early spring are the most common times for this problem to occur. Try to increase temps and airflow to prevent it from reoccuring on other leaves.

    So nice to see a Phal with the same leaf issue as mine! Those leafs are still living, and the new ones are undamaged. My plant is potted in a bark mix In a vented ceramic pot.
