    This withering looks disquietingly leaf in plant's centre.

    You mean, it could be the plant rots or suffers from the inside of the stem?

    The problems continue, and even increase!

    Now four leaves are starting to get yellow or brown, some at the root, some at the tip. Two leaves already fell down.

    Have of each root length remains brownish when getting wet instead of getting greenish.

    The plant is now as before in my bathroom to take advantage on the air humidity there. Each time I am using the shower (between 2x to 5x a day) I also spray the water over the hanging plant. One time each day I place it in a big buck of water with a trace of 20-20-20 fertilizer for between 20 to 60 minutes. Despite of being mounted at the window of the bathroom, I am certain the light conditions are not reaching 1,000 candle foot.

    Please assist me to save the life of my plant.

    Hi,
    In my opinion:
    You need to give this orchid ALOT of light plus when you immerse (just the roots) you then need to let it dry out & put where there is air movement so it dries out I think :
    1. you immersed too long... 1 to 2 hrs?.. If you ever do that again (I have forgotten it in it's bath for a whole night a couple of times) I then do not water for at least 2 days. I would not spray it either ...
    2. water has 'stagnated' in between the leaves and therefore rotted the joint between main stem & leaves.
    These are 'tough' plants so should not be a problem getting her 'fit' again
    just make sure you soak roots and give her alot of light.
    I have mine in a s/sw window and she flowers every year (mostly twice)
    I once lost 'a leaf' in the middle of the plant it just became yellow & dropped off. (I had left it in somones care for 6 weeks whilst on holiday) it only flowered once the following season ...
    Good luck & keep us posted

    Hi, thanks a lot for your advises!

    I decided to give a lot of light, and put it upstairs on our roof terrace, where I measured the amount of light with around 3,000 candle foot at 2 PM.

    Your thought that water has stagnated between the leaves and caused the rotting, is quite catching. I never thought of that, but i believe that you are right. Having the plant upstairs now in the Caribbean sun, I hope the remaining water will evaporate fast. To soak the roots with water, in the future I might just bring it down into my apartment and rest it agin in the buck of water, but this time only for 15 minutes. I wonder if I should do this each day or each second day?

    Or should I just take a wet wash rag upstairs to wet the roots, what do you think? And should I use plain water, or the rain water I find inside a (rusty) big metal tin upstairs, or water with a tiny dash of 20-20-20 fertilizer?

    I would use rain water but NOT if it is collected in a rusty/metal bucket!
    Can you not get a plastic bucket to collect rain water?
    Whilst you collect rain water you'll have to use the water you have (plain)....
    I do not think rags will be enough! especially in your climate.
    Yes I fertilise mine too in almost every 'bath' I give it. But use half the strength of fertiliser than it says on the packet/bottle of fertiliser.
    In your climate up on the roof you probably need to do it at least every day.You need to get her to start growing new roots and leaves first.

    Can you post a picture of the whole plant including roots & leaves?

    That all sounds plausible, Nen. Thanks a lot, again. My appreciation for your help!

    Sven immediately stop using fertilizer on your plant. Don't let the crown get wet and remove it from the bathroom, you also don't need to submerge the roots in water for 15 to 20 minutes. Check your water supply to see what is the hardness of the water, if it very hard with a lot of sodium in it, your plant will die slowly. Pot it in a basket with charcoal and styrofoam. Cover the top with coconut husk or good quality moss, so that the sun doesn't strike the charcoal directly (the charcoal can become very hot). Water it every morning before 10 am and in the evening before 4 pm. Don't wet the crown, just the roots. And don't fertilize till it produces new roots.

    Great advise, too! I will combine it with the advise above from Nen.

    One question: how to test the pipe water for hardiness and sodium contents?
    I need to submerge roots for only 15 to 20 minutes, or not (how then)? Wasn't understanding when reading that.

    You can get the water tested from a lab, but many cities publish details about the water supply on their websites. If you pot your plant in a basket with the above mentioned media and water it twice daily at the mentioned times, you do not need to submerge your plant. If you decide not to pot it and let it stay bare root, then you can mist the roots 3 or 4 times a day and If you don't want to do this, then submerge just the roots in plain water for not more than 5 minutes, you could repeat this for 3 to 4 times but not longer, keep the stem, crown and leaves out of the water.
