Repotting / dividing dendrobium - Orchid Board

Have a very tightly packed den that needs to be repotted. Not sure if I should divide or just repot into a large pot. I've never dealt with type of den before so I'm a little lost on the best course of action.
Trying to attach a pic of the patient!

If it was mine, I'd break the pot, extract the existing medium and repot into a larger pot.

Dividing should be kept to a minimum of 2- or 3 old growths plus one new one, but that looks like a healthy specimen in-the-waiting.

I agree with Ray. A large specimen is much more impressive the several small divisions.

I wish I had not gotten the bug to divide some of my plants when I re-potted....sigh, I will lose some now, instead of having more. So take my advice and let them grow and let the experts divide!

Managed to get it out of the pot & remove most of the old material. I was leaning towards just repotting the whole plant, but wasn't sure if it would be better to divide. Will be repotting the whole plant.

Well, as has been said above, a large impressive specimen looks the biz. Far more so than a couple of small ones.

if its happy and not dead in the middle no reason to divide it so you did good

often with older catts they will start to die off in the middle, leave a hole and too many unsightly old canes that need to be culled. Then its times to cut it up.

Looks like Den aggregatum or one of the others in that group. They do well mounted, but perform best if allowed to grow large (if you can call a plant with 4" bulbs 'large').

Cut back on watering now. From mid Nov till it blooms, no water at all. If it has not budded by March, it is skipping this year, so you can start watering again.

I agree. Looks like my aggregatum. I have mine growing in a plastic Vanda basket.

Fairorchids, I could never get mine to bloom with the dry winters until someone at our OS told me two years ago that they water theirs normally throughout the winter and it always blooms for them. I tried that last year and it bloomed for the first time for me. No idea what to think as I had always read it needed that dry period, too.
