    Angry Dedrobium no leaf but keikis



    What's wrong with this Dendrobium: no leaf and flower but keikis. It had flower last year and dropped all leaves. Any suggestion and advice?

    These Denbrobs (nobile type) need a dry cool rest period which for you would start during the 2nd half of October right through untill new root activity is noted,most likely when the new growth is about as high as on the plant in the photo.Also a smal pot for this type as,I have one that has six mature canes and its in a 3inch pot.
    During the rest period do not worry about cane shriverling(sp),this is normal,but a missing say once every 2-3 weeks would be OK.The temps for this dry period can go down to 0 C or 32 F at night and about cat light or higher.
    The keikeis are nornamlly produced if the canes are not matured correctly,as they are where there should be flowers.

    ditto on what Murray has said... all that I have read about this type of orchid mention the dry rest period during the cooler months to initiate flowering... failure to adhere to this regimen means that they will throw up keikis instead of flowers...

    on the up side... look at all those plants that you now have!!!

    I have this type of dendrobium (soft-caned) as well, and I divided these keikis, so now I have 3 pots. This is one of the good thing of soft-caned dendrobium.

    Dendrobiums are the devil, best thing to do is toss them and buy some Paphs.

    I agree, I haven't gotten any dendrobium to bloom for so many years....

    My hard caned dendrobium bloomed this August and had lasted for 3 months, after I had been waiting for 4 years! It's not hard to grow, but I found that they really need a lot of sun before they bloom. Some people say it's easy to grow, but I don't really agree.

    Hey Smartie2000 and Tony, what happen to your dendrobiums?

    What I read is you need to cold treat them and whithold water until you seee buds on the spike. Water too early will turn the spike into keikies.

    I have warm type soft cane dendrobium which does not require dry and cold spell. I started put it outside at night and brought it indoors during the day, and water it once every week (I need to water it very 2 or 3 days when it was in active growth). It sent out a lot of spikes now, I hope they won't turn into keikies.

    My oldest dendrobium, which was a phalaenopsis type, got frozen by accident from a overnight frost. A soft cane dendrobium also died when I moved to my new house (too little light, stress and forgot to water):-(. I'm jealous because my grandma was able to bloom her phalaenopsis dend which was the same clone that we bought for her. BTW it was her first orchid too! She's lucky though because she has a small glass house growing area built into her house.

    I recently bought a variegated dendrobium moniliforme and a soft cane dend hybrid (one of those who don't need as extreme winter treatment as regular nobile hybrids). Hopefully I will be more lucky. I see little growth right now. I dont know if its a keiki or bud. I shouldn't have any problems providing cool temps because my windowsill gets really cool in the winter.
    ...still waiting to bloom my own dend....

    The soft-caned dend that I have is dendrobium nobile. Does this one need winter treatment?
