I have two Mock Orange trees/bushes that we planted mid season last summer. They are both doing well and one is blooming. I believe they are named "Natchez" and "MN Snowflake". They seem green and happy. My question is, are they supposed to be all loose and floppy? Both are just kind of falling over and neither has a central leader. Should I cut them back after they finish blooming this summer? I'm not afraid to do this really but just wonder if that's the best way to proceed.

Thanks.
