You have to tell the readers what sort of Dendrobium you are talking about because culture varies according to type.
Google Phalaenanthe Dendrobiums and Nobile Dendrobiums and select images to see the type or tell us what is on the plant label.

If you got it at HD then hard cane Dendrobium hybrid is a good guess. These are watered completely different from the Phals and need a LOT more light than Phals.

To water a Den, run water through all parts of the pot for 30 seconds, then let it dry. If it is a little dry, don't water, wait another day or two.

Arthurm I got the label and it says dendrobium pink baby, that is what is writen there with not much information. I will look up images for the phal on google.

Richardol thanks for the watering information. I am going to pickup another one today I will take pictures of this one.

If the name is Den. Baby Pink rather than Den. Pink Baby it is a Phalaenanthe or Phal Type Den with the ancestors coming from Northern Australia. Culture as Riichard said. Watm conditions, good light and less water in winter.
