Eli5: How a growing tree avoids growing branches into each other.

Question

Title. I’ve never seen a tree where two or more branches have collided while growing. How does the tree “know” where all the branches are while growing?

Answer 1

Not sure what you mean by “colliding”, but tree branches often grow “close” to each other, or overlap each other. Pruning one of them out will improve the health of the tree.
