    Default Can this dendrobium be saved?

    I did serious damage to my dendrobium phalenopsis. Had bugs so I sprayed with malathion. Within a couple of days, all of the leaves turned yellow and began to fall off. When i saw what was happening I thougherly rinsed the plant and potting mixture with water. It seems to have helped as 3 of the 4 canes are green although there are no leaves. On one of the canes, the top is turning black in some areas, but the bottom up to near the top is still green.
    Should I remove the entire cane or just the affected area? If I do, should I cut the green part into sections in an attempt to clone the plant? When you clone a dendrobium, are you actually creating a near mature plant or is it similiar to a seedling?
    I really like this plant so any help would be greatly appreciated.
    Thanks.

    I am not sure the malathion caused your leaves to turn yellow and drop. We spray with malathion here (mixed fairly strong) and have not had that problem. I am thinking that maybe your dendrobium is one that looses it leaves in the winter? Or it could have been the bugs that you were spraying to kill. They may have damaged the plant so much that the leaves fell off.

    The black part of the cane could be caused by sun burn as well as a bug.

    If the canes are still green and there are plenty of good roots, I would not cut the orchid up and attempt to clone it. It will probably recover in time on its own. If there are no viable roots, then you can consider attempting a clone. This is a time intensive process though. It *might* be easier to simply repurchase the orchid and start anew.

    Good luck.

    Cheers,
    BD

    Thanks for the advice.
    One more question, this dendrobium had 5 canes when I bought it and 3 never had leaves, two are mostly brown and one is mostly green. Should these be removed? The person whom I bought it from said they are used to store water and nutrients and should not be cut. What do you think?

    I would agree in principle, but if you post a photo that shows their condition, I could tell you what I would do.

    Cheers,

    BD,
    Thanks for your offer to help.
    Here are pictures of my dendrobium.
    Hope they are clear enough to diagnose.
    Do you think I should leave it alone or cut and try to clone by using the cut sections?
    Any advice would be greatly appreciated.

    I would not cut it up at this point. It still appears very green and it does not appear to be going limp so it must have some good roots. Just because of the time involved, I would not attempt to clone this dend if I could purchase another. Look on-line if you do not have a vendor close by and see if you can purchase another copy of this dend.

    I suspect that yours in time it will grow a new growth and 'come back'. I have seen several that look exactly like yours that come back and bloom.

    Good luck with it.

    Cheers,

    In addition, the plant may produce keikis on its stem. If it does, once these have gained a bit of stature with some roots, they can be detached from the parent plant and potted up separately.

    Cheers,

    Good morning BD and Rob,
    Thanks for the advice, I really appreciate the help.
    Based on what you say, I will leave this dendrobium alone and hope for the best. If it did indeed grow a keiki, it would be my first and I would be more than very happy!
    Have a great day.
