    Default yellowing tip of vanda leaves

    Tip of leaves of a V. sanderiana is turning yellow. What might be the cause for this? It's summer in the Philippines so I water my vandas 4x a day: 7 AM, 12, 4, 10 PM under filtered sun. Other vandas in my collection did not show this weird behavior. I've just sprayed Dithane fungicide two days ago if ever this is a fungal attack...

    If you could post a picture of what you are describing that would certainly help us determine what might be the cause.

    I cannot be of help with this, but I find it interesting. The photo looks like damage, maybe from snapping against something or flapping (like a flag) in the wind. Like palm leaves damaged by wind.
    I have, and have had several vandas, but haven't seen that damage before.
    Does it continue? Get worse on same leaf? Has it spread to new parts of the plant?
    Wish I could be more help. Maybe someone will have other ideas.

    Thank you for commenting. Early this day, I noticed that the yellowing was climbing up to healthy tissues of the same leaves. So to prevent the infection from getting worse, I cut off those yellowing parts and sprayed fungicide. Hope the plant gets cured. I'll be posting an update if the yellowing continues.

    John I agree with you cut off the yellowing parts it's not good I dont know what organism it is but so infectious, after you cut please apply cinnamon powder or you can spray fungicide by the name " Benomyl' reduce the frequency of watering keep him dry, avoid the rain water for time being after he consider improved than slowly put back into your desire location. Another alternative use powder of Benomyl to seal the fresh wound. So far it's work for me hope for you too.
