orchid leaves dying starting from stem

This is a discussion on orchid leaves dying starting from stem within the Orchid Ailments / The Compost Pile forums, part of the Orchid Culture category; I googled 'Aerides', and some of the flower shapes looked pretty similar, especially one that ...

    I googled 'Aerides', and some of the flower shapes looked pretty similar, especially one that was Aerides x Vasco. Also, the spacing of the blooms on the spike in that photo looked similar to mine (not as tight as the species Aerides). Do Aerides have branching spikes, though? From the photos I saw, the shape and quantity of leaves seemed right if this is an Aerides hybrid. But, then again, I don't expect to find anything at my grocery store except Phals, Dendrobiums, or Oncidiums. I think I'm more unsure than ever about what I've got. I look forward to getting opinions if I do get this orchid to bloom again. What I do know is that the blooms are adorable.

    Jen, I'm sorry about the lost mini, and I'm sorry you don't have an answer as to what went wrong (My guess would be the poor care it got at the store before it came to your loving home).

    Thank you to everyone for the advice so far. I'll let you know if this orchid hangs in there or not.

    A:
    When I was not quite a beginner, and trying to get watering right, I did a few experiments , like this. I weighed a plant ; no pot, no compost. Then I weighed the pot, then added the compost and weighed again, then watered very thoroughly, drained, and weighed again.This told me the weight of water in that pot when very wet.

    Next week I just weighed the pot again, and noted how many grammes weight lost - how much of that water was lost. I kept a record , without re-watering , week by week, which showed me that the loss reduced as the pot dried out. I then decided at what point to re=water ( 1/2 the water lost was the point I chose ). It also told me the typical proportion of water in any pot weight - at least it did after I had repeated this on half a dozen different pots.

    I ended up with a tag in every pot telling me the wet weight, and the weight at which I should water again. Kitchen digital scales are very good for this.

    So watering consisted of looking at the tag - “water below 250gm” for example - put it on the scales, water, or not... easy peasy, and after the initial experiments it added only moments to the watering day.

    I could go on, but you get the idea ? Science, not guesswork...

    another way to determine if watering is needed is insert a bamboo skewer into the potting medium (trim the skewer down so that it just fits in the pot). When you think it may be time to water, take the skewer out and feel it. Is it damp? Don’t water yet. If it’s dry, it’s watering time. You can feel the pot after watering and just before and get a weight idea.

    My big old 37 year old Phal started to go bad this spring. It didn't bloom and seemed to be sulking. I realized I hadn't repotted it for 2 - 3 years and repotted it in a slightly bigger pot. It didn't seem to like the medium and started dropping leaves like mad, very much in the style of yours, but fast, one after the other. I say root damage, either from repotting or rot (from its original potting?). In my case I think the new medium didn't drain well enough and my roots rotted. Because it was a large plant, I pretty much quit watering it and started misting it instead. It got down to one leaf and has stopped losing them. The roots are obviously sad and pretty well gone and I am babying it along, hoping to see a new growth. I'm scared to even pull it out of the pot it is in now, I don't want to give it more trauma. It is the one in my avatar and we used the flowers at our wedding, I really don't want to lose my baby!!

    Anyway, it looks like root damage to me. Be sure it dries out between waterings, but, as it is a mini, keep the humidity up pretty well and water it soon after it dries out. Good draining and good airflow and you should be able to bring it along. Good luck too!

    Wow this is pretty amazing!

    Also, very good info to know, so thanks.

    Well, this is indeed a mystery! I can't wait to see what the flowers look like when the plant blooms! I would be VERY surprised if a grocery/box store here in the North was carrying an Aeredis hybrid, but stranger things certainly have happened! Make sure to post pics when this plant blooms so we can solve this mystery! I know my curiosity is certainly piqued!

    my guess is that between the initial over watering you were rescuing it from, and some shock of being re-potted the plant is unbalanced and is just trying to adjust, it lost most of its roots, so it has diminished capacity to take in water, so in an attempt to keep itself hydrated, it is shedding a few lower older leaves. water comes in through the roots, and out through the leaves, so it is trying to conserve.

    i don't see any obvious signs of disease, or rotting from bacteria or fungus. the leaves would develop 'sores' first that spread. this looks more like normal leaf shedding, just happening faster due to the loss of roots.

    i have bought a few in this condition before. this is why we call them rescues. quickly getting them out of the rotten moss is half the battle. the few i have lost in this situation all died really quickly after bringing them home, like within a week lost all leaves and fell apart. i chalk this up to dehydration. they were just too far gone and weak to come back. meanwhile, i've had a few go right down to just a leaf and a half, and eventually come back. a long time later, actually!

    one thing i recommend is to take any questionable plant, and when re-potting, remove the old moss or bark, water the roots well, then dip the whole thing in the sink filled with water and a little bleach. it sounds drastic, but does not harm the plant, i'm careful to wet the roots first, so they absorb more clear water first, then dunk them in the bleach for a little while. rinse them off, then place them into fresh bark mix or whatever works for you (sorry, i do well with sphag???).

    during recovery, just like with any patient, a little extra care is needed. humidity helps orchids heal and grow, so a little less light and raise the humidity, but not just by watering more often, you need the air around the plant to be humid, this helps keep the orchid (i think) from losing water faster than it gets water, so you lose less leaves. you can place a glass dome over the plant, or set the whole thing into a clear plastic bag. eventually the plant will regrow enough roots to become balanced again and begin to return to normal. the roots will come first though, so don't panic when you don't see new leaves, give it time. once the leaves begin to grow again, you've made a full recovery.

    I hope this orchid is strong enough to recover. I want to see it bloom again.

    Carolla, that is such a beautiful Phal. How cool that it provided flowers for your wedding! I really hope it makes a full recovery for you. Keep us posted.

    Jenn, when I bought my mini, I definitely thought it was some type of Phal hybrid that I'd never seen before. And every time I think of the place I bought it, I still think it must be a mini Phal. For cultural reasons, I wish I knew for sure. Other than that, I mean I knowingly bought it as a NOID, so a name will not change my opinion of it. I was just captivated by the tiny blooms. I had never seen a Phal with such tiny flowers. It was so cute that my no grocery store rule and my no NOID rule went out the window. It followed me home.

    I'm worried now after clicking on the link in another thread about diseased leaves. The damage in the second photo looks like the damage on my orchid right now. Judging by the photo, it seems my orchid might have what they call collar rot (crown rot?). The info in the original link recommended Cleary's. I can get that, but is it safe for use inside an apartment? Is there another option?

    You can compare their second collar rot picture with a new photo of my orchid:

    I had that exact thing happen to a couple of my "bag baby" phals. It's rather insidious, and often by the time it shows up as an obvious problem, the plant is a goner. In my case, the orchids this happened to all came from the same batch... I believe the whole lot was infected. I bought one, which died, and then I bought another, and the same thing happened. I didn't know it was called "collar rot" at the time, but I could tell it was not good.

    See if you can pry that bottom leaf away from the base of the plant a little bit and get a good look down in there. Do you see any black stuff? Also, give the base of the plant a squeeze. Is it soft in any way? These are both signs of collar rot. I was able to halt the collar rot on the third plant I bought from the batch (I really liked that particular orchid) by pouring a mixture of water and physan down into the crevices and folds in between the leaves and the base. I also removed the leaves that were closest to the base so I could let it "air out," and I used a q-tip to get the physan mixture down into all the little cracks where the rot was setting in.

    Once that did its work, the rot was all gone, but it had eaten a large part of the "collar." The plant made it, though, whereas the two before it that had gone untreated died.

    If you don't have Physan (it's available online), you can use full-strength hydrogen peroxide. Pour it down into the little crevices where those bottom leaves are emerging. If the base of those bottom leaves are yellow (which it looks like they are), you may want to gently remove those leaves to expose the stalk of the plant. You'll be able to see if there's anything black or mushy inside, and you'll be able to treat it more effectively than trying to get past those bottom leaves.

    Basically, if "collar rot" is what this is, it IS treatable with physan or another sterilizing agent like hydrogen peroxide or a mixture of water and bleach (9 parts water to 1 part bleach is generally recommended, but this rot is REALLY aggressive, so I'd recommend the hydrogen peroxide instead). You have to catch it early, though... otherwise it will rot through the whole crown of your plant, and one day the whole thing will just be slumped over and mushy.

    Considering what you're seeing, I would advise being a bit more aggressive than using the "wait and see" approach. Get as good a look as you can at what's going on at the base of the plant, even if it means prying those yellowing leaves off from the base. Once you expose what's underneath, you'll be able to treat it if you see anything yucky. If it's brown or smooshy in any way, pour peroxide on it. Wait until it stops fizzing, then rinse the whole thing off. Keep a very, very close eye on it. You may need to treat it again with peroxide if the rot isn't all gone after the first treatment. Basically, the rot should "dry up" when treated properly. If this is collar rot, that's the only way you're going to save your plant.

    Regardless, if it does turn out to be collar rot, know that this is not your fault. It would have set in before you had transplanted it; it was probably there when you bought it, and it's just showing signs now. Still, the plant is savable if you act quickly. Pry those bottom leaves away from the base and see what's going on in there!

    Gosh, I wish you luck... I'll be biting my nails over here waiting to find out what you discover!
