    Default Phal Orchid Leaf Rot?

    Hi everyone! I bought this GORGEOUS phal about 2 months ago (I love saving them and giving them a better home ^_^).

    This current phal is still in bloom, came with bark, and has 2 stems.

    Although the flowers seem to be okay, I noticed that there was always a "black dot" on the crown area of the leaf (it came like this from the store). I didn't know what it was, so I ignored it. About a month later, the leaf that had the black circle turned yellow and fell off. About 3 weeks later, another leaf (one that was underneath) turned yellow and fell off. Right now, there are about 3 normal leaves left. The top-most leaf tilted alot due to the sunlight's angle, and now is practically snapping off due to the weight. I examined the base of the plant, and saw tiny roots trying to grow out---but turned black and died, before being able to grow to their full potential. Nothing else has happened since. None of the other plants in the area are effected.

    I have a photo of the plant:

    Name:  leafrot.jpg

    What I am wondering is:

    1) How to treat this condition

    2) If there is any hope for the plant to survive at this rate, since the top-most leaf is practically snapping off, and I haven't seen a new growth at the crown.

    I really would appreciate any help anyone could give!

    Hi, I have had problems with my phals. such as yours. I believe yours has a bacterial infection, I have treated mine with PHYTON 27, either in a soak or spay. If you choose to try to save the plant it will take quite a long time if it survives. I have had mixed results when the top-most leaf is lost, I have almost thrown plant out when just happened to see a new leaf coming from the old roots, just remember it will take about (3) years before you get any blooms.Good luck if you decide to try Hank........

    Another remedy is lots of cinnamon.

    I guess since it's a natural disinfectant, it'll kill of the bacteria naturally?...

    This looks like crown rot to me. It's a fungal infection and needs to be treated with a fungicide, like Physan 20.

    Are you getting the crown wet when you water? This is a common mistake when first caring for phals. If Physan doesn't work, I'd recommend discarding it. You definitely don't want the infection spreading to your other orchids. I hope this helps and good luck.

    Ted,
    Cinnamon is a natural fungicide/disinfectant. It might not have enough "power" to treat major infection, but I used it on several cases of rot with success. I just cut out the effected area and plaster the cut area with cinnamon. After that I keep the plant on the dry side for few weeks. I also read a recommendation to soak cinnamon in alcohol overnight, strain it and then use the liquid as a spray. I try not to use chemicals on my plants, in the winter time especially, because I am a window sill grower. I have kids and pets, my hubby has a sensitive nose, and my house is small. So, if the plant is meant to live, cinnamon is the cure.

    I have dogs and children as well.
    My thought was that this crown rot looked quite extensive and may not respond to cinnamon. For my last resort I use Physan. I always bring it outdoors away from the house. I use clothing that covers the arms and legs completely, rubber gloves and a surgical mask. Showering and laundering the clothes follows the treatment. Leaving it outdoors for a few hours after treatment is best.
    Being in the medical profession I am very cautious about chemicals but also appreciate their benefits.
    Let us know how the orchid is doing.

    Wow...Ania...That is great info...Funny...Here I thought I knew EVERYTHING...(Just kidding). I have just read a few things about cinnamon.You got my curiosity up. I am now putting cinnamon in my vodka so I can avoid liver cancer...hahahaaaa...(again, just kidding).. Seriously, I had no idea that it has the benefits it does and will keep it in mind for the future in case my plants have a problem. Thanks so much for the heads up. Afterall, I am near the cinnamon hub of the world here...(but born in Mystic, Ct.) Cinnamon is everywhere here and so inexpensive.

    It's good to know that about cinnamon - I have cats and am leery of chemicals myself. Do you wet the cinnamon to plaster it on, or just dust it on? I've a couple of plants I'd like to try that with, they aren't in bad shape, but show signs of spotting and I'd like to be sure they thrive.
