Thank you everyone for your comments. I did not prune them at all. The red one was grown in a larger pot, and the plant itself grew larger. The pink one is still in small pot. Here is a photo of the rest I am waiting to bloom. They begin getting full sun around 11am until the rest of the day. My plumerias are also in full sun about the same period of time. Our temps are predicted to push possibly over 100 this week, until a "cool" front on Saturday. I am thinking about moving them into a different location while I am off work today, to keep them from stressing. Do you think that would be necessary?
