    So I have had this beauty for about 9 month now. Slowly but surely the leaves have been falling off the stalks, and not replacing them selves. So do I cut away the bare stalks or leave them be. And when the leaves start to go bad they get yellow spots and slowly but surely the whole leaf turns yellow and dies. Not sure if this is a natural shedding or something else.
    One more quick question, are those air roots or something else part way up the one stalk, the second picture?

    As long as the old pseudobulbs are green, they are still contributing to the colony through photosynthesis and storage of water, nutrition and energy.

    If they "yellow" naturally, from the tip down, it is an indication that the colony is resorting everything from it, amid it will become a parchment-like "husk". If, on the other hand, it becomes soft and "squishy", I'd remove it .

    Jnowak, the roots midway on one of the canes looks like a keiki (Hawaiian for baby) which, when big enough, can be removed from the mother plant and potted or mounted.

    Many of this group of Dendrobiums are deciduous or semi-deciduous. Many also flower for many years on the bare canes. So, as Ray stated, the bare canes are very important to the plants well-being as well as the future flowering.

    Is this Dendrobium pendulum?

    Would you say that the "baby" is big enough to re pot, some of the roots are as long as my hand? I'm new to the orchid world so not 100% sure, This is the tag ImageUploadedByOrchidsForum.com1447526598.634404.jpg

    its just roots if it doesnt have a baby plant already growing. you could try some keiki paste, what ever its called, right where the aerial roots attach to the stem.

    Could you post a photo of where the roots are attached? It is hard to see in the other photo.

    Jnowak, it is certainly a keiki and it looks like there are two canes already. There are at least 2 ways to remove it. Many, perhaps most growers, say to use a sterile razor blade and gently and carefully slice the keiki from the mother plant. I have attached your photos below that I have drawn the separation line on.
    Personally, I grasp the keiki as close to the mother plant as I can then gently pull and wiggle it like pulling a tooth. Sometimes they will come off very easy. If you get too much resistance resort to the razor blade.
    You can pot or mount the new plant. It looks like it may be blooming size already.

    Sometimes a twisting motion helps dislodge the keiki. Assuming you are in the northern hemisphere, your plant will be going into a winter rest period and you may want to reduce the watering. You might consider waiting until spring when you start to see new growth before you take the keiki off so it will be ready to start growing again.
