    Default Dendrobrium leaves thinning and dull

    Hi,

    When I purchased my dendrobrium 3 months ago, the leaves were thick and waxy, however the leafs have since thinned and appear dull. I initially noticed the thinning in leaves of the new canes, but it seems to have affected the mature canes. What is wrong with my plant?

    Not getting enough water. You need to check the roots to see if they have rotted. Remove the plant from it's pot, carefylly removed the bark from around the roots (soak in warm water for several minutes, that will help make the roots more pliable.) The dark, slimy roots are rotted. The squishy gray roots are also rotted. Trim them off. Repot in new bark. Do not water your dendrobium until the bark mix it is planted in is totally dry. This is just basic general 'rules'. I don't have many dendrobiums, so maybe someone with more of them will chime in with more specific instructions. Good luck!

    Cindi has given you good advice. It is weird to think that it is getting too much water when it looks like it needs more water, but that is what happens when the roots rot. Yours is not too far gone yet, so there is hope. Pot it up in new mix after cleaning up the roots and then let the medium dry out before you water again. You can mist it if you live somewhere that is very dry, but keep air moving across the leaves.

    Cheers,
    BD

    Thank you Cindi and BD for your response. How can I tell if the roots have rotted? Visually, it does not seem very different from when I first bought the plant. I have also attached a photo of the roots of my dend for your reference.

    Some additional information that might be useful: I water my dend on a daily basis every morning. The exposed roots and potting medium (charcoal) seem dry to touch by night time.

    How is it inside the root ball? Unpot that dend and take a look at the roots. It could be that the only viable roots are those on top of the medium.

    cheers,

    Makanmanna, welcome to the group! I really like the hard cane Den. phals and have 7. Mature canes will naturally lose their leaves. Still, your comment about the leaves on the newer canes worries me. I believe you are overwatering yours if watering daily. The plant stores water in the hard canes both leafed and leafless. They really like to have the potting medium completely dry out. The roots will keep sending water to the canes (rotting the canes) if the medium doesn't dry out deep into the root ball. Or, the roots will suffocate/drown and die. You should only have to water these den's every 7 to 10 days. Check out this care article:

    This type of Dendrobium does not re-flower on an old spike. So to save the strength for the plant, we trim the spike when the flowers have all wilted.
