    Sriram, how do you water your vandas? assuming they are in basket or bareroots?
    I was thinking: I was soaking them in container , so the one which is not doing great was sitted in basket kind of dip so lower leaves axels were sitting in water at watering. Could it be the reason? some kind of root? Soaking in physan 20 did not change anything

    Svetlana, most of my vandaceous's are bare root and some (top cuttings that i received) of them are potted in CHC + charcoal and all of them are grown outdoors. I have a battery operated power sprayer and I spray to the roots till they are completely green. I spray once a day and I have a misting setup that runs 1 minute for every 1 hour between 10 a.m to 3 p.m

Someone suggested to summer them outside to help. Butbi don't see any improvement! The one that was ok still fine with green growing tips but the troubled one still going downward. Leaves are drying up and no growing tips on roots. You can see on stem there are few bumps like new roots will grow, but month past snd they are in same condition.
    Do you think there is something else why these vandas leaves are drying?!
    Could be a number of factors - the bottom line is that they are losing moisture faster than they are taking it up. The humidity (as one poster pointed out) could also be a factor, too. Mine were exposed to a constant moderate breeze which would slowly dry them out to the point of dying. I had a 6 ft fence that blocked some of the breeze, but not enough. I covered the gaps for the most part, and that helped, but it is still a battle. If I don't give them a good misting daily, and sometimes twice daily, they will quickly shrivel up. If I had heat, low humidity and the breeze I could not keep any of them alive. Fortunately, the humidity rarely goes below 70%, and I use shade cloth to prevent the sun from heating/drying them too much. It will slow the blooms down, though.

    I'll see if I can get some pic's tomorrow.

    Well, it seems that I'm quite useless, because no matter what, it continues to die, she gets now one new yellow leave each day. It makes me so sad, I guess I shouldn't buy online, but here you can't find vandas and when you find one is really really expensive, because I think 90€ for a vanda is expensive.

    Dont loose hope!
    Like Sriram suggested treat it with some fungicide (i know mane pesticides banned in europe but try find some!)
    My vanda looks like yours except leaves not turning yellow but shriveled all to the newest ones.
    I took it to work so i can mist it anytime roots dry up. Lets see if it helps.
    I would try anything to save 90 Euro!

    I concur with Svetlana. Don't lose hope on it. I have pulled an orchid from the brink of death when I thought it had no hope. Wow 90 euros! That is expensive. I was wincing at $35 US dollars for my Vanda because I wasn't sure I could keep it alive.
