How to get dendrobiums to flower?

[nancypantsy]

I have a dendrobium that has purple flowers. I lost the tag so I do not know its name. I have had it about 3 years and I have split the plant into 2 daughter plants and re-poted them. I'm getting vegatative growth on both, but not flowers. The leaves are a medium green.and look healthy. Do I need more light, or should I put the plant in a cooler area to initiate a spike (thats what I do to get Phaels to spike). Any suggestions would be helpful.

Try letting it dry out for a few weeks for a rest.

They like to be pot bound for blooming. If the recent growths are mature and the plants are in a south facing window and you are letting them dry out between watering then patience is all that's called for.

If you have different conditions, let us know and we can help out.
