    Default Miltoniopsis psb and Masdevallia Leaves

    It's almost 2am here in Singapore and I'm still staring at my orchid and trying to figure out what is wrong with it.I would appreciate any advise please.It's very urgent as I'd have to buy whatever is needed to combat these diseases.The psb is turning reddish brown suddenly and affecting the leaves from bottom up.Maybe the coconut holds too much moisture and it's some fungus?My masd leaves turns brown from tip, not from fertilizer.I cut off into healthy leaves and sprayed hp on it and left the fan on.But it just comes back again.Trying to load pictures here...can't see an option for it.

    If you look at the bar just above the reply area, you will see icons. Click on the little picture image and it will give you the option to download the pic from your computer. Navigate to the file and then upload it.

    The picture needs to be sized no larger than 700 x 700, so be sure to edit before trying to upload.

    Reddish brown could be sign of too much sun or deficiency of magnesium. what is the light exposure?. direct sun or indoors?. posting a picture would help. inspect the roots if required. if the roots are healthy then should be ok.

    Sadly I don't think it's Sun.it looks like water soaked I'm guessing rot.But the roots are dried up not soft and mushy though.I just brought this plant though.has a funky smell too.I cannot see the option to post a picture via phone.will do so when I get to a computer.

    Miltoniopsis and Masdevallia are cool growing orchids & cannot take too much sunlight. In singapore, you should keep it in air-conditioned room or in cool place. If not , they will slowly deteriorate over the time. Even if they survive, it will be very difficult to bloom without cooling/temp drop.

    Falling leaves & reddish pulb is probably due to heat stress of singapore or due to new environmental changes or suddenly exposed to strong sunlight. Keep in cool & shady place & pray with Captan fungicide to prevent further infection.

    One of my Milt. also had that problem. The leaves would start turning brown and would die off. The pb turned orange. It slowly spread to the other pb's. The Milt was in my house in AC in the same condition as another one. When I finally got down to one pb, I unpotted it, cut off the orange ones and left the one out in a clay pot with no media for two days. I did mist the roots once a day with water. I also sprayed the cut area with Physan.

    I repotted the good pb. this was about a week ago and it seems to be doing ok. It has a new growth coming out of the side of the pb and the leaves are still ok. The issue seemed to be some type of bacterial or fungal infection.

    Good luck!

    Physan is a good choice for a possible fungal infection. A lot of people here use it regularly to keep their orchids healthy. It doesn't cause damaged tissue to become healthy though, the plant has to grow new pb's and leaves and roots. I find Masdevalias really hard to grow, its not cool here. I've kept mine alive for over a year and feel that is a success. Mostly I've tried to keep it damp but not wet and not too hot. If it dries out, it loses leaves, if its stressed, it drops leaves, if its too wet the roots go bad and it loses pb's and leaves. Recently I put it in S/H (semi-hydro) to see if it will like that better. I'm hoping the dampness and evaporation of the water in the reservoir at the bottom will keep it cooler and it will start to thrive. It hasn't given up yet, so I haven't either. It grows just about as fast as parts of it die... .silly plant! Sometimes we gain and sometimes it loses. I love Masdevalias though, so if I can dial it in, I'll get more of them.

    Default Masd. hirtzii

    Hello Carol!!! Nice to hear from you.I agree with you about masd.I have one just a try out.It's from ecuador. Masd. hirtzii is the name. I never liked it but it has grown on me.I agree with you about it being hard.I have no idea if I'm successful.I stare at it a lot.I know I seem crazy.But I just try to observe it frequently and try to see if it lacks something or has too much of something.I wish you lots of luck! I'm soaking everything in physan now.It's tiring.ten orchids to clean up.I'm happy to hear from you it's commonly used.so I'm positive now.
