Roots of new growth dying

[Moss1414]

I have a Cycnodes ‘Wine Delight’ producing a new growth, and it was doing well for a while. Now the root tips of the two longest roots have turned black and stopped growing.
How can I prevent this from happening to the other roots?
I’m growing indoors in a south facing window in sphagnum and bark.

This is actually the time that most catasetum plants are in dormancy. Did your plant go dormant earlier? And have you been watering? Watering too early can cause the new roots to die back, in my experience. A picture would be helpful.

I stopped watering in November, but it never really went dormant. It shriveled a lot and then lost it’s leaves, as opposed to my other Cycnodes which has been without water even longer and hasn’t shriveled at all.
Both of them are starting to produce new growths though. The new growth of ‘Wine Delight’ is starting to have leaves, and honestly looks a little thirsty. I’m confused.
I’ve had trouble posting pictures here but I’ll see if I can. Thank you.

A rule of thumb for judging watering is to let the roots be 2-4 inches long before watering. I water very carefully around the perimeter of the pot if there is substantial shriveling of the bulb from the previous year, but you have to be careful not to get the new roots and growth wet, or they can rot or stall growth. Good luck!
