    Hello Gardeners,

    I'm having problem with white mold inside the pot of my one Phalaenopsis.

    I recently reppoted it with new barks,
    I'm worrying about it because I did holes in the pot and im afraid this might be the cause of the problem. It didnt happen to with the old one in a pot without holes before repotting it.

    The pot is inside the cachepot.

    I just tried to flush it with water and it didnt change quite nothing.
    The mold is like cotton. I post my other 2 big Phals which i also put holes along with the first one.
    The first is in the hall of my house near a window while my 2 phals are in my room. Do you think the problem is caused by holes? do my phals in my room gonna get this mold as well? Should i worry?
    Thank You.

    I always water the first one (with mold) a lot because it has few roots and because it was in leca clay so the roots are used to being in contact with water otherwhise it cant sustain its leaves and buds.

    I really doubt it has anything to do with the holes. If you have (or can get) Physan 20, you could mix some up at the recommended dosage and soak the pot in it for 30 minutes. Alternatively, I would probably use some 3% hydrogen peroxide (as it comes from the drugstore) and flood the pot with it or put it in a plastic container and soak it in it for about 10 minutes.

    Ok, i opt for the 3% hydrogen peroxide, even though i never understand how to use it.
    Is it 50 ml to 1 Liter of water (example)?

    Look at the label of what you have. Cosmetic and food service concentrations are in the 5 to 36% range. What we get in the US in drugstores is 3%. That is what I use just as it comes from the bottle. If what you have isn't 3%, let me know and I can calculate the amount you need to dilute it.

    You can try to kill it by following Marni's suggesion, but if you are not allergic to mold, it won't harm the plant. It's probably just saporophytic fungi (only decompose dead organic materials).

    I'll gonna try to buy 3% hydrogen peroxide, but first i going to move it in other place and if the mold get worst im going to proceed for the chemical.

    Thanks Marni a lot for helping, i appreciate it.:)
    Thanks to you as well Naoki. Im only afraid itll gonna multiply in entire pot and thats woud be a nigtmare.

    Have a nice day.

    UPDATE

    hello, I just resolve the problem by removing the cachepot/decorative pot. I didn't mentioned it because it was big enough to make the air flow around it but that's is the cause.

    Have a nice day.
