Dendrobium Aussie's Chip roots question

[catttan]

It is a an evergreen hard cane hybrid of the latouria type. (Den. Aberrans x Den. Atroviolaceum v pygmy). These roots sure look dead. I cleaned it up( I cut the roots that were literally falling off its string in the center) and re-potted and I am hoping for new roots in Spring.

Both aberrans and atroviolaceum are from the rain forests of Papua New Guinea and enjoy high heat and humidity year round. I have not seen D aberrans except in pictures but some of my fiends grow atroviolaceum and it has the most gorgeous lip not unlike spectabile only beautifully coloured. They are not deciduous like the soft cane types.

I think you have done the right thing by cutting off the dead roots and repotting.
