    I have found out that bleach works for getting rid of mold & fungus. I use nine parts water to one part bleach. I spray the whole orchid, then lightly brush it with a small brush. Then I rinse with regular water. Hasn't hurt my orchids, and got rid of the fungus!
    Try it...I'm sure it will work for you...Betty :-)

    Hi Espranch, I am having a nightmare with my orchids at the moment they all seem to have some root rot in their pots. It's not really bad but I would like to put a stop to it once and for all. I have tried dusting with cinnamon but I found that that worked only on the roots at the top of the compost so I am now contemplating using your method with the bleech. I am just wondering, do you spray the whole plant once it has been taken out of it's pot and then repot it in a new pot after spraying? I thought that it was submerged in a bucket of bleech and then repoted. Are both methods acceptable? I am going to buy some compost on wednesday so if I buy some regular bleech as well that should be alright shouldn't it?

    Susie...If you are going to re-pot them, be sure to soak the media overnight, first. Then, un-pot the orchid, and cut off ALL black or rotted roots first, with a sterile knife. Then soak them in a nine parts water to one part bleach. Soak for five minutes. Rinse with regular water, then, re-pot. Some where on this site there is a thread for potting...try to find it. I do hope that you have SOME live roots left...Let me know "how" it goes. By the way, my name is: Betty. Good luck. P.S. After re-potting DO NOT WATER FOR AT LEAST A WEEK TO TEN DAYS!!!

    Thanks for that Betty. I was unsure how to go about it. If I don't need to repot I'd rather not but I thought that it was necessary? So I guess if I don't repot I just spray them instead. The thing is most of the black soggy roots are right at the bottom of the pots so I just thought that to get to them I'd need to get it out of the pot. If I can just spray it all over instead that would be better for me as they are all blooming at the moment and I'd hate to lose even just one flower. Thanks for the advice Betty, I think I'm going to just spray them all instead and hope for the best.

    Susie...Be aware that rotten roots can & do affect the whole plant. If they were mine...I'd cut the flowers and put them in a vase to enjoy...Then save the plant by getting rid of ALL rotten roots, then re-pot the plant. However, they belong to you and you can do as you wish. I wish you luck...Betty :-)

    I haven't repotted it yet but I will be doing it on wednesday. I am just going to pour the solution through the whole pot and leave it for five minutes. However, if that doesn't work then I will definitely repot. Most of my newly acquired Orchids seem to be suffering so for now I will just pour it through and hope for the best. Fingers crossed...
