Thanks for your response.
This a.m. I looked and one more pb has turned yellow. I am going to cry.
I won't be able to see roots, bz I don't want to disturb it to see. I remember when I was repotting it, I noticed that each pb was a separate plant. I think they put individual pbs into the pot to make it look like one plant. This makes me want to buy another to see if that is how they grow naturally and if I can make it flower. Thanks again.
