Dendrobium lamyaiae

I purchased this last fall and have gotten it through it's dry period apparently successfully. I don't know when I should repot it so it is in a fresh medium and what it needs in the summer.
It is putting out a new growth and there are some indication of some growth on the old canes, maybe flowers?
It is in a 2" net pot lined with coconut fiber, I can't determine what it is actually potted in but it doesn't seem good.
This is the first I have grown so small a plant and needing a dry spell. I don't know how to treat it to keep it alive, suggestions please.

 

DPfarr, Thank you,
I am also wondering if I should repot it, the medium it is in feels not very good, it is almost impossible to see it in the picture. If so, into what it is so small?
There are some indications of growth at the old leaf scars on both sides of the cane at the bottom of the picture.

 

Chuck, Thanks, I hadn't thought about mounting it, I don't know why. You are right, the way it is now I can't tell if it is growing new roots or not. I am assuming that it is because of the top growth.

 

Here is an update from March, I mounted it on a piece of cork, it grew several new bulbs and the put out many beautiful flowers. It is now drying off this summers leaves and getting ready for it's winter rest.
