If a man hammers a nail in a tree that is 5 meters and comes back after a few years and sees the tree has grown to 10 meters – but the nail is in the same position – how does this happen?
The answer is that trees grow from the top. Each spring new growth (height) is added from terminal buds that are located in the topmost parts of the tree. So, a limb that grows from a tree 3 feet from the ground will always stay attached to the main trunk at a point that is 3 feet from the ground. The trunk will grow in diameter each year, so if the nail doesn’t do too much injury to the tree, it will eventually become embedded in the tree.
