You are asking the impossible. What sort of Dendrobium is the mother plant? Where do you have it in your home? What are the temperatures there? How big a pot did you use for the baby? etc. etc.

Hi arthurm
Don't know what kind of dend. it is. Got it as a gift that came from Lowes a few years ago, I keep it in the living room with my other orchids near a window and the temp is between 65-68. Pot is about 4" wide.
Thanks for your reply

A four inch pot for a Dendrobium keiki is way too big! You have to simulate how the plant grew in nature....on a rock or on a tree with the roots running over the surface. So you would start off with a tiny pot size and as the plant gets larger gradually pot on to a larger pot size.
