I thought I noticed a new cane starting to form at the base in the picture too.
I have a leaf tip on a new cane that is turning brown. So I too am looking for ideas. Orchid-man provided this link regarding dendrobiums in an old post (5-11-2006) that is interesting. It appears to be a research article.
I believe that Dendrobiums do not like repotting if their roots have not restarted into growth after their (winter) rest - assuming they require a rest. The reference to sulking may therefore be approppriate under these circumstances.
I agree Gin there does seem to be a new growth at the soil line. I just want to weigh-in on the watering factor. During the winter I had my dends inside and watered 1x a week and they looked awful! Now they are out under 70% shade cloth, getting rained on almost every day and they are growing like crazy. Go figure!
I have a Den that was overwatered by a helpful boyfriend. I have transplanted it. Roots white, dry and brittle. I do have new growth, one new stalk. One stalk is pale, has a leaf that is yellowing. Do I cut this one or leave it alone?
Leave the stalk unless it is obviously dead...a leafless stalk can still be providing energy to the plant...and some dends bloom from leafless stalks as well.
If it is pale, it may be that it has been sunburnt-new growths are susceptible to it. I would cut it off it goes mushy, but leave it on otherwise. If the roots are dry and brittle, they are older roots-just repot into a bark mixture, because most orchids LOVE the air around their roots (they naturally grow in trees or on rocks-epiphytes or lithophytes). Just water when the top looks dry, and im assuming its dendrobium kingianum? If it is, they LOVE water year round. Just dont let it sit in water, or any orchid for that matter, with one or two exception, and make sure it is not moist before you water, if it is, then dont.
My den looks just like this one, except it is totally leafless now. One stalk is pale green and the smaller one has shriveled, dry and brown at the top. Roots are thin, white and shriveled. I don't know whether to transplant it, water, what kind of light or temp to give it. It's in a small clay pot with bark/orchid material. I want to try everything I can to save it. Suggestions greatly appreciated.
