A big one got small/-er

Today I transplanted a maple I got in 2007 in a tree nursery from one pot to another. Since the tree is already growing strong, I didn't cut almost any roots.

2007 still in the nursery.

 Two years ago.

Today. In the future I will have to plant this maple more to the center of the pot. This time the roots didn't allow mo to do so.

Some time ago this one was for sale, but now I'm not so sure anymore :-)
