Dendrobium Victoria Reginae with root problems

[JKeys]

I purchased a Dendrobium Victoria Reginae a couple months ago, and it bloomen nicely. One thing that struck me was the number of nice whit healthy roots is had! I potted in fir bark in a clay pot when I gor it. It was in sphag when I purchased it.

Now, its has lost a couple leaves, but has a new growth on one of the canes. There is also a weird greenish bump at the top of one of the canes. But whenever I water, the old root ball is brown, with half yellow/brown roots. I put it into an oxygen core pot so I could see the roots better. All of the visible roots (5 or 6) have brown tips. What should I do, if anything at all?

The new green bump may be a spike or keiki

Roots sometimes take on a brownish color from the bark. I don't know if that's what's going on with yours. Are the brown root tips shriveled or rotted looking?

The ones on the top are, its too hard to tell about the ones in the mix.

Hmmm... just the tips of the roots look brown?

how much do you fertilize?

[JKeys]

I fertilize once every one - two waterings.

Do the roots look plump and firm?

[JKeys]

i can't see that many - only tips - and the tips in the pot look plump, but the tips at the top are squishy. It may be because when I repotted into bark, I didn't completely remove the sphag at the top of the pot. I didn't want to remove it because if I did it would break all of the roots.

If the roots in the pot look good, I think it's fine. You could snip off the squishy tips from the surface roots, but it's probably not necessary to do so.

Is your avatar photo your victoria-reginae? It's lovely!

That's not of mine, mine flowered before I got a picture. But that is what the flowers on my plant looked like.
