    Was this leaf already yellowing to drop off or did the yellow spread after the spots appeared. Sometimes leaves before they drop attract more mold from sitting closer to the soil. Once the leave falls or is removed, no harm is caused to the plant. The second option is Edema, which is caused by overwatering where some defect in the plant causes it not to stop "drinking" even after its full, causing upraising water pouches that can cause damage to your plant through fungus, bacteria, etc.... best thing in this case would be to dry the plant out for 24 hrs then more closely monitor your water regimine.

    Hello, my friends! My phal is in a very bad condition. Mould is spreading time after time on the roots. I want to pour some remedy in the pot to stop the mould. What can I use?

    That's the way the roots look like. Right now there is no mould, I've cut all the roots in mould, but they look too bad. The mould appears time after time. The leaves are droppy. I don't know what to do

    If it is affecting ur plant that badly it my not be fungus or mold. usually in these two cases the best remedy is to dry the plant out and remove the soggy soil. If this doesnt help then I dont know what will. A Pic or better description of this so-called "mold" would be more helpful.

    Ok now that I see it I can tell u. When ppl see roots and leaves wilting because of lack of absorbtion it is in their instinct to water. Wrong move. At this point, it needs more air than water and it seems ur replant provides the perfect flow. Remove some of the lower leaves to try and boost the plant into regrowth. Too much watering can block airflow in the soil so try to keep it bare minimal and allow it to completely dry between waterings. By what I can see u are doing fine it just takes some patience for a severely distressed plant to recover. Kinda like if u got the flu and ur boss wants u to be better by tomarrow... not gonna happen until it happens. .

    The roots that you see is almost all the roots that my plant has. The roots are very dry, I don't water it often, but mold appears sometimes. And it is blooming now. Should I cut the flowers off? If so, please tell me how to cut the spike.

    Let it finish its cycle first. In order for mold to appear it needs standing moisture. The plant is receiving that moisture from somewhere. If its not from u watering it could be collecting moisture in the air. If this is the case try dipping the plant up to the closest roots to the crown (without watering the crown) in water since those look the healthiest. After that don't water it for a few days. It could b ur medium looks dry but is retaining some kind of moisture. I know moss works similar too. Even when it looks dry it may still have something retaining. Reason I say clipping those roots wouldnt hurt it is because they are basically lifeless now and not able to hydrate plant. They are nothing. Shortening them a little won't hurt. Avoid the ones that still have some green to them.

    Lijun, I'm really glad you told us about your experience of following the instructions on a video - (note to self, watch all of the video before following instructions!!!) In the immortal words of Homer Simpson, "DOH!"

    Has anyone considered that from this view the roots have very little medium around them and may not be getting sufficient water and too much air? From the size of the leaves I'd say it's a mature plant and should be in a bigger container with more medium around the roots.

    Considering the condition of the leaves it looks like an effective remedy is required soon. They are nice buds and flowers but for the sake of saving the plant - I'd repot. I've had phal's in bloom and successfully repotted with no sign of problems or loss of blooms. Good luck Annie, I hope it begins to recover soon, T
