    Unhappy Den dying?

    I have a den. uniwai beauty which I bought a couple of months ago. It had four canes, one of which was a new one. Well, that one grew and made one leaf. Now, the canes' leaves are yellowing and now the new one's leaves are starting to yellow and fall off as well. After that happens, assuming they all fall off, will that mean this den. is doomed? That will make it an orchid without any leaves on any canes...is that bad?

    Did you say the new growth is still growing?

    Well, I'm not sure now...the bottom leaves on that one are starting to yllow and fall off, also. However, a woman put a classified in the local paper that she had orchids and exotic plants for sale. So I called her right away, of course . I went there and she had, literally, hundreds of orchids. Mostly dens, catts and hybrids, some species, oncidiums, etc. She had been doing it since the 70's.

    I was floored, but I couldn't afford the more mature ones...
    Back to the point, I took a look at her orchids for comparison purposes and noticed that they were ugly! They were all wrinkly and black dotty--and she had had them for years! So, I didn't feel so bad. Also, her mediums were getting algae (again, mature plants she had for years) and were moist. So, now I'm totally confused. They were all outside. I'm so green with envy. I did get three one year old catts that had previously bloomed and getting new sheaths. I wish I could've gotten more. I felt like a kid in a candy store! :lemmetell:lemmetell:lemmetell:lemmetell

    sounds like that plant needs to be repotted immediately. the leading cause of a drastic change like this is probably root rot. pseudobulbs can provide the energy for new root growth. dormant buds should still be viable in most cases and will send up new growth in time.

    Some dendrobiums are deciduous. They drop off all thier leaves before flowering, and then send off new shoots after the flowers died. As long as the canes remain green, don't give up on them.

    I agree with Jmoney and would repot this den to make sure the roots are not rotting away. Keep us posted!


    Cheers!

    Yeah, check the roots. What are the conditions of the canes? Green, yellow? Shriveled, not shriveled? I know that den canes can get shriveled if they're underwatered or overwatered. Without good roots, they're unable to take in more water so the canes start getting wrinkled and creased. If your canes are plump and green, then it may be OK. But, however, to be on the safe side, examine the roots. Root rot is a possiblility.

    Why would you guys suggest repotting of all things? Anyway, I mounted it this weekend. IT's down to 3 leaves, and the bottom leaf is starting to yellow at the tip. Other than that, I think it looks ok.

    Root rot is black mushy roots, right? Or does it look like anything else? TIA

    oh, also, the new cane has stopped growing. In other words. there were no more new leaves.

    I am thinking of potting it again, tho.

    a high percentage of cultural problems in general are root-derived. if a plant isn't doing what it's supposed to be doing, and there's no clear reason for it (i.e. rot), then i repot. most of the time i'll find my answer--hollow, mushy roots. even if the roots are fine, it's not an exercise in futility because now you *know* the roots are fine. and if the roots are fine, they won't usually mind a little gentle repotting. exceptions apply, of course, some plants like vandas or whatever hate to have their roots disturbed. that's just what i suggest, others may agree or disagree.
