comment How does a plant decide when to grow a branch?
Great answer Richard. Upvoted. You refer to a chaotic process that determines new areas of auxin concentration between meristems as the plant grows, so I guess the simplest answer to my question is "chance, within the confines of a system". There doesn't appear to be any DNA-style central planning at work.
