    Default update on my den lindleyii - mixed success

    A while back, i posted a picture of my Den lindleyii, and was advised that it needed to be repotted. I did repot it that following weekend, took pictures,
    and have not had a chance to post an update. Here's a picture of the Ded out of it's pot -
    yeah, it kind of looks like it needed to be repotted.Name:  den lindleyii - pre-repot.jpg

    I was wondering whether to divide it - there was some growth happening down inside the pot, and wondered whether I could bring that out into the light without detaching.
    Well, the plant had it's own ideas and split into two pieces. Then,
    when i went to pot the 2nd one, that also split into two. I was being very gentle,
    so this plant was definitely telling me something! Name:  Den lindleyii - repotted.jpg

    All three pieces are growing roots, and some new leaves on 2 of the 3.
    The one without new leaves has just started to grow roots very recently,
    so I think it will send out leaves very soon. I had thought one piece was sending out a flower spike, but it turns out to be a keiki. I may end up with quite a collection of these plants!

    I am concerned about the older leaves.
    I continue to have problems with them yellowing from the tips inward. They turn yellow, then develop a brown stripe, this progresses as the leaf dries and falls off. Is this normal aging or some sort of disease?Name:  den lindleyy - leaf discoloration.jpg

    This time of year there shouldn't be a lot of growth but as long as there are still bright new root tips I'd keep watering. I don't know what is causing the leaves to die back like that but the plant could be drawing nutrients from them. How much light are you giving them? This is one that is in 1" chunks of cedar and charcoal. I was watering it daily through the summer but now only once a week and in November I'll cut back to every two weeks until January when the spikes start to show.

    Chris - that is a lovely plant! I hope that someday mine look that good!

    I wonder if mine need more light and water? Before re-potting I placed the plant on a table about 4-5 feet inside sliders with an overhanging deck. The deck is rather high, and the sliders are south facing, so this is still very bright. My plan was to move it to a sunnier spot after a period of initial quarantine. The leaves started to do their yellowing almost immediately, and the dark line concerned me, so I have continued the quarantine - perhaps for a longer period than necessary.
    As we're back and forth between two homes, watering is not ideal. If I go to the other house on Thursdays, I'll water then and then often water again on Sunday. Sometimes I don't arrive until Friday evening - will water then unless it's already dark - then will water on Saturday morning and just mist things on Sunday. Not ideal - look forward to moving in a couple of years and only having the one house. Humidity varies - often naturally at 60 percent or higher, seldom lower than 40, though an occasional dry, sunny and breezy day will drop it to 20%. If I'm worried about humidity, I water again or mist everything.

    I'm still setting up my grow area, so I will try to figure out a way to get this plant into more light without it being right up against some other plants. I have a large shelving unit in the basement of our first house - need to clean it off and get it to the second house - used to use this with lights when I grew orchids in a north-east corner of a prior home.

    My grow space with the orchids is south facing, with a thermal heat sink wall at the the back, floor to ceiling windows, with one pane that wraps around to the east and to the west, so it's very bright - almost like a greenhouse.

    You mentioned that when you re-potted that the plant broke apart into three pieces. I think (from that description) that the connecting tissue between the pb's had begun to rot. It will take a while to recover from that but it does look as though it will recover. The roots we can see are all aerial. If there are none going into the medium it may be that the medium is too wet and the roots are being maintained by humidity. The one in the Vanda basket dries in a few hours. As to the leaves dying back? Your plant looks as though it may have lost a leaf or two since you re-potted but also gained one or two. Try drawing a line with a marker where the living and dead tissue join. I'd be willing to bet that when you check back in a couple of weeks, that brown won't have spread. Worry plays tricks on the mind

    Hmm - will be interesting to see what I find tomorrow when I go to our other house. Last week, I cut two of the leaves - just about 1/8 inch into the green part. One of the leaves turned yellow beyond the cut, the other was green. I like your idea of using marker instead.

    There are aerial roots, and there are also roots growing toward the medium. When I think about it, the plant didn't have many healthy young roots in the medium before I repotted it - I think it was overdue for potting. So, maybe the damage that's been happening since repotting is just residual damage, and the plant will start looking healthier.
    Thank you very much for your support.
    I need to find more time to get to this forum - there's so much knowledge and willingness to help. Seems like a nice group of people.
