Pruning top out of coral bark maple

Q: This will be the 3rd year for my Coral Bark Japanese maple. Until this past fall/winter it was very well shaped. Suddenly this wild thing sprouted out of the top. What should I do about it?

A: It looks to me like it became a teenager, growing taller daily on the way becoming an adult tree.

Coral bark maple is a comparatively large Japanese maple. It grows naturally to 20 feet tall and 10 feet wide. I suspect the new growth is just the tree’s attempt to grow to its mature size.

That said, there is no reason you can’t remove the limb to keep the tree at the size you like. You will get the best results if you make the cut at the base of the limb. This may leave a “hole “in the foliage, but the tree will fill it with new growth within the year.
