Mounted DENB has yellowing leaves

boothbay(7)July 2, 2011

I decided to try a mounted Orchid a couple of weeks ago. My Denb had bloomed this pas late Winter. I attached it to a bark and all seemed well. I left the roots exposed cause of the heat of the day and the humid conditions we have been getting. I have it outside my porch in a bright light with morning son for about a half hour. The roots being exposed, I assumed that i had to spray them not only daily, but 3 times or so...plus douse it with water and fertilized weekly. At the beginning i had 1 leave yellowing , but today i saw 2 more for a total of 3. I suspect that i am over watering it with spraying. I did cover the roots with transparent plastic wrap, perhaps the roots cannot be exposed?

You probably have a hard-cane Dendrobium, i am assuming this because you said it flowered in winter.
Might not be a problem if the leaves are falling from the oldest cane/psuedobulb.
You might have to spray several times a day if you are trying to grow a cloud forest orchid, as for covering the roots with a transparent wrap, that might create a mini hot-house around the roots and cause damage.
Forget about all this tropical stuff, and read some hard cane culture notes on the net to get a feeling for the type of culture required.
Those pseudobulbs/canes are there to get the plants through hard times.
Does the plant have a name?

Yes, it is a hard cane and almost 2' tall. I lost the tag that came with it 5 years ago, so no name that i can recall. Two leaves that are yellowing are at the near top of the cane, and one is on the "pseudobulb/cane"

I have not successfully mounted hard cane Dendrobiums. Some died, others lingered without robust growth.

Hard cane Dendrobiums do best in any medium when the roots dry between watering. Daily watering (not just a little mist) is fine.

The wrap is not a good idea, and may be the cause of the leaf loss, or it could be shock from the re-pot.

I have mounted Den species, but I keep the hard-cane hybrids in rock. This are like Great Dane puppies, cute in the store but they will get larger and larger with each new growth.
