How do trees decide when and where their branches grow?

Also related, the Fibonacci Sequence.
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377…
If you divide each term by the previous, you get
1, 2., 1.5, 1.66, 1.6…, all converging on 1.618…, the golden ratio.
If you start at one point, shoot a branch, then turn 1.618…times around the trunk and shoot another, and go along that way, you get the most efficient structure for a plant to produce a canopy for maximum top down area.
Which is really weird.
